TD edit hyperlink to non site vendor removed search for dtechproducts

I ran across this while searching for PMD modules. It sounds promicing. Thought you all may like to read about it. Any of you vendors out here a dealer for Dipaco? Have they released them yet? Anyone have a price on them?

1 year warrenty or 7 year warrenty? My minds made up...

I understand about Heath's warranty if you buy the package. Just passing along the fact someone else has stepped out and tried to pay attention to the common faults with the old unit. Dang, pig headed around here sometimes. Its just information people.

From their site Why use a DTech PMD?

Higher Temperature Rated Components
The components used in a DTech PMD are rated to an average operating temperature of 125o C versus 85o C for the original equipment PMD. Using the temperatures in the chart above, you can see the DTech PMD components are rated well above the expected operating temperatures while the original parts are not.

Flexible Material Inside The PMD
If you take apart an original equipment PMD you will see it is filled with a very hard epoxy-like material. As components heat up they require a certain amount of expansion room. The hard material used by the OEM does not allow for expansion thus causing additional stress on the components and circuitry. The DTech PMD uses thermoset flexible potting material, which allows for thermal expansion as well as providing vibration absorption.

Thicker Heat Sink
The DTech PMD uses a thicker 11/16” anodized aluminum heat sink providing for greater heat dissipation. The OEM only uses a 9/16” thick heat sink.

Improved Transistor Mounting
The two transistors in the original equipment PMD are mounted to posts using nuts at a very low torque specification of 2 to 3 in. lb. Due to heat and vibration the nuts can back off and the transistors can become loose, causing intermittent problems. The design of the DTech PMD allows for a higher torque specification for the nuts. Then, an epoxy is applied to the nuts after installation that bonds the metals together. The result is a more stable assembly.

The DTech DT76301 PMD includes the PMD, mounting bolts and pad. The wiring harness, part number DT30882, is also available.

Could be a soultion emphasis on the could, again I'll offer up same advise if it is THE SOLUTION where is the warranty that backs it as being such.

There is another product RemarQ SOL-D wholly different design warranted for 5 years, good thing as many folks using it have had cold weather issues & it not being able to start.

Remember new & improved isn't always so, sometimes it is just new.

Not pig-headed, just skeptical. Why, if their product is so good, they are only confident enough to back it with a one year warranty? Heath is willing to back the old, crappy design with a seven year warranty. If a company is going to tell me something is new and improved, they had better be willing to back it up. Thanks for the info, it will be interesting to see if these go the way of the Sol-d.

I just got off the phone with the guy. $149.00 1year 50,00 mile warrenty. It sounds like they just totaly redesigned it eliminating the inherent design flaws. He is working with a guy that will offer a remote mounting kit. The PMD will be available in mid september. Did I mention $149.00 and can't you find pre made harness extensions. Arn't the heat sinks just a hunk of aluminum? I won't be suprised if the heavy hitters like Heath and Kennedy look into this. It has passed all it's trials in heat and cold but it's still new so........We will see.

Any site vendors Dipaco dealers?
I know the injector install kits that kennedy sells are made by Dipaco. At least they were 3yrs ago when i bought one. Dont know if that means hes a dealer or not.
 
#10 ·
What I do find interesting is that they seemed to have addressed the heat issues - which being in Arizona, concerns me greatly.

I don't necessarily have an opinion about this new makers, too early to say. But I know one operation that is very,very,very nervous:

edamweb

this jack-leg on gaybay that has been peddling used pmd's like this:

This PMD is in very good condition TESTED on a 50,000$ BENCH and also tested on a running truck for 1 week (about 1000km of running). Our PMD have to pass all these tests before selling them. We dont just test them 20 minute as many other sellers do. They are in fully WORKING condition and that's guaranteed for 2 months.


If I had my choose of a new, redesigned PMD with a 1 yr warranty for $149 or an intake valley baked OEM unit with a 2 month warranty for $69.99 plus $20 shipping, I'd probably would buy the Duramax(JUST KIDDING).

Time will tell the tale on this one. It would be a great option for someone who already has one of the "other" coolers.

One more thought, exactly how much clearance is there between the PMD and the lower intake on IP-mounted drivers? The description says that it has an 11/16" heat sink VS 9/16" OEM, will an extra 1/8" thickness clear the lower intake?​
 
#12 ·
Well, I know that on a Hummer (using the 6.5L TD van engine), there is likely not enough clearance because of various components that are crammed in there.

Of course, a lot of owners (myself included) have already remoted our PMD's - so converting to this new DTech unit won't be a hard thing to do.

Well, for only $149, I guess it could pan out for use as a replacement for someone who has killed one by putting it on a heatsink under the hood and wants to use the same heatsink somewhere else.
 
#14 ·
If only Heath or Kennedy would endorse it all the walking talking billboards here would call it a god send. Till then,...
Me, If I could grab one for $149, I'd whip it out and order it today. Dipaco seems to have a sound reputation in the diesel parts market. If I can hold out till they are released, I'll guinee pig one for the mases.
 
#15 ·
Bud for whatever your feelings about "talking billboards" guess I fall into that category at times, I don't know of any "billboarders" that do it out of any brand loyalty for loyalty sake.

I've been a 6.5er since 2000 myself, member of multiple 6.5 boards, and have seen many a "new product" come & go, most times they go after guys jump on the bandwagon to be the first to have the new & improved & the new product has left them light in the wallet & still broke down as well.

As a group the 6.5er has been so burned by GM/Stanadyne to begin with, & multiple "improved" products we are severely jaded; so until someone shows us without a doubt it works we cheerlead what works & throw up the caution flag on any new promises.

Far too many times have we seen empty promises on driver longevity, only one that has proven to be up to the task has been the Heath backed by the warranty no other vendor matches.

Bear with us if it appears to be "cheerleading", but there is a reason for it, if it weren't true what many say here about a particular vendor it would get out fast the vendor did not live up to the commitment.

The vendor list you see in the vendor listing is about as good as it gets, so please bear with us when we talk billboard, we have seen a lot of good & bad stuff over the years, & have healthy skepticism to new, maybe overly so, but how many times can one get burned by unsubstantiated claim and not tend to get jaded.

I don't know where you come off with this thinking. I've been trying to call every 6.5 related sponsor on this board out over a product they all sell, and none of them will step up, but when something works, I'm going to give credit where it's due.
 
#17 ·
I'm with the masses, Why if the (FIX?) was so easy?........Why didn't standyne upgrade their own product?......(Is it to sell more PMD's?.....Isn't their reputation as important as their bottom line ($)?).......and also, wouldn't stanadyne have the most working knowledge of their own product?......I really don't know the answers to these questions......but untill it proves itself for the LONG RUN....(Sol-D being the perfect example)... IMO you'd have to be at least a little leary.
And why such a low price? If they truly corrected this horrid PMD problem.....I think it would be worth at least twice their amount.
Then of course you got the warranty........Thats were Heath has them all beat......
Just food for thought.......You've got to be a little skeptical, at the least!

TD, I hear you! I'm new in the 6.5 world. (probably says it all) If and when Dipaco gets the PMD modules on the market, if the pocket can afford it I'll try it out and speak from experience, till then I'm gonna let it go and Thank everyone for their feedback, insight and words of wisdom to use caution when its new and improved/unproven. Thanks everyone!:)

"As a group the 6.5er has been so burned by GM/Stanadyne to begin with, & multiple "improved" products we are severely jaded; so until someone shows us without a doubt it works we cheerlead what works & throw up the caution flag on any new promises."

Sounds like experience shining here TD,(something I don't have yet) Thanks for helping with the board and being so polite here and in pm!

rhino, I understand Heath's warranty. He's proven get the PMD out of the heat and it will last. His warranty is definitely his proof in his confidence in his product.

Glad I could share something new and thanks again for keeping it real.
Sorry it hasn't been proven yet, maybe I can change that down the road and say its been running for 1,2,3, years or say it lasted 12 months, 1 day and49,000 miles and everyone will get to say "Hey Jackass, told you so" and it won't be the first time I've heard that.
NOW :beerchug: :stirthepo :pig: :saluteusa: :anitoof:

Thanks again for everyone's opinion! I do understand the new and improved usually isn't. Knowledge is power my friends, thanks for all the power on this place. Back to searching for poor MPG threads.
PEACE!

You got to get yourself a lot more experience to back up statements like this one, bud...

Your statement is truly irrelevant. Heath and Kennedy don't make the PMD - Stanadyne does.

All Bill Heath did was find a way to keep the old Stanadyne product from failing. I respect anybody who displays the guts to stand behind their product, something that I'm not yet seeing from this new wundertoy.



But I tell ya what... if my Heath unit ever dies, outside of the 7-year warranty, I'll sure consider your DiPapco unit.

However, since nobody I know has been able to come up with a genuine failure of a Heath PMD Isolator, I doubt it'll be an issue.


And welcome to the 'Place, by the way. You might think that we're all Heath/Kennedy fans, but that's likely because you waded right in here talking, instead of listening. There's a lesson in there...

Only reason I can think of is to "buy" the market.

Sell enough cheap units to chase competitors out of the market, then raise prices.

Can't think there is enough money to be made in 6.5 FSDs to buy a Caribbean island and retire in comfort, so who knows....;)
 
#21 ·
I will take one "for the team" and order one for my remote setup. Considering that my DieselC_re and Performance "good used" PMD, which was actually a hack repaired-job, only last about 5 weeks on my remote cooler (in the bumper nostril). I am now running on the faulty backup unit on the pump that throws the DTC 35.

Assuming that these Dipaco units are available now, I should have one in my grubby little paws by early next week. I will document the experience with the Dipaco unit from start to...?

Regards,

TY for the warm fuzzy welcome. Must be the fur.:D
I have listened to a lot I've read j. I was trying to share something new, didn't think that was a bad thing. I was kinda hoping I'd get responses along the lines of dipaco makes junk, don't even try it or I've installed dipaco products for ??? years, they make a good product, this may indeed be worth checking out. I realise my "pig headed" comment set the tone for being bashed-I apologize for that, still my intention was letting the board know about a possible improvement on what seemed to be an old nagging problem. Heck, if they stand up to pump mounting, think how long they may last on a heath setup or some other remote locate design-other option is they burnout quick and cause more problems than they are worth. Hell man, I don't know just sharing, its my way. Not just sharing, everybody gets their own. ROFE:)

I asked Kennedy for a price. Hoping I'll hear back tomorrow. He did state they were untested and not released yet. Somebodies gotta test them. From what TD said, you guys have been burned by many'a new and improved products. That said, I'd still be willing try one but not so sure the old PMD is gonna make it till they are released. I'm gonna try and hold out though.

Did stanadyne's cost to manufacture go up or did they realize they control the market on this unique part? From what I've read, the old PMD units didn't start out with the over $400 list price. Its like wallyworld, when you have no competition left, you charge what you want.

Goldsburg, sorry your unit died so fast. Stories like yours has kept me from stepping out on fleabay and buying used. As its been stated around here, once the damage is done, its DONE.

Was it TD that tried to keep an old one alive by tightening the screws, sanding contacts and other TLC type things but in the end it died, it was just a slow death?

Well ladies and gents, it certainly got things riled up. I'd still like to try one, put my money where my mouth is and see how it goes. We can't take it with us.

Peace People
 
#24 ·
OK bud, sorry I poked back.

It was the comment about Heath/Kennedy and walking billboards that got me riled, BTW.

I like it when people share new things, or question the norm... we need that, just like everybody else. However, I don't think the comments you got back about the 'comfort factor' of Heath's reliaility and 7-yr warranty were out-of-line, either.

I'm quite pleased that Golds is gonna try one out on a remote cooler - that will get us some REAL data.

The PMD thing is a very contentious issue, bud. Lots of guys on here and other diesel boards look at Heath's price and run out to buy a competitor or build their own... most of the time, they save $100 because the PMD is $400 by itself. Then theirs dies and they're back here complaining.

I figure it's like the Fram commercial... "pay me now, or pay me later". I always want to ask "so, how do you feel about saving that $100 now, huh?

Sometimes I do... I just can't help myself.

Some guys, like Golds, build a solidly-designed remote kit and try to see if a used-but-good PMD will make it out there; on purpose, knowing that it might fail, but willing to take the shot just to see how much abuse a PMD can take and MAYBE save a little $$. So you see, there's 3 levels of PMD user here...

--the safe (bought a Heath kit),
--the sorry (bought a competitor or tried something they were warned about and now are doing it again),
--the searching (trying to find another way).

Those of us classed as 'safe' live with both the others just fine, but then again, they usually don't get uppity because we don't have a love-in with their trials and experiments.

Know what I mean?

This board as do most of them; has a low threshold to guys new to the forum throwing darts regardless of experience they may have, takes time to get established as "one of the guys", sort of like visiting a new neighbor and first thing you say is Hi, gosh that is one ugly dog you have, may be true but not best way to make new friends. At some point the owner may even comment my dog sure is ugly what do you think, meaning you are in, you just are too new to throw darts yet, so you got some backlash there, give us a little time to get to know you, I'll bet you fit in.

Lets move on guys to the question at hand nuff said

As was in the point to ponder study the PMD did die on it's own accord eventually lasting a little less each time, so damage is cumulative from my experience, which is why I try to steer folks from the "used but good" driver suppliers, unless you get 2 one to run and the other for the spare when it dies.

I still carry a spare even though I'm Heath remoted, it is still a Stanadyne driver & may fail, the warranty isn't so much to me the Heath remote driver won't ever quit, nut that if it does beyond normal circumstances of control/mfg quality it will be a covered item.
 
#26 ·
^^ this is why I like this place

OK - as was stated, Golds trying out the critter on a known good heat-sink should give a good test. At $149, it's a heck of a lot cheaper than a Stanadyne, and as long as it doesn't have the electronic and reliability issues of the SOL-D, this might well be the next great thing.

I still can't see it lasting on the IP, but here's a thought... if it works as well as the Stanadyne on a remote mount, I'll bet Bill Heath might be interested in mounting IT on his PMD Isolator... dropping the price and retaining the reliability. He might even make a little more money on each one, which I wouldn't mind if we could also save some $ on each one...

Something for everyone... finest kind.
