I WANT TO USE MY 6.2l DIESEL TO POWER A PORTABLE SAWMILL. IS THERE A GOVERNOR AVAILABLE FOR A STATIONARY 83 GMC 6.2l DIESEL?

I moved this from FAQs, which is a reference area, not for adding new posts, post may become part of reference material but initial posting needs to be in main forums.

Why not use a cheap Audiovox cruise control system. Like $100 from jcwhitney or pep-boys. Just an idea.

There is a pump...I can't remember the model number, but it is specifically designed for use on a 6.2 generator. I'm sure if you take your pump to a diesel shop they will be able to make it for you.

Thanks for moving the post TD. As for the 6.2, I have an old 70's vintage hobart welder that uses an inline 6 cylinder engine. The goveror is belt driven and has a rod that connect to the throttle. It seems this type of system would be fairly simple to make work on a 6.2.;)

The nice design feature of the Roosa-Master pump is that the governor system can be tailored to the load and speed of the intended use for the engine. I believe a good pump shop could modify/calibrate the pump to a load advance for use on a constant speed application.

I might be all wet on this but I inquired about this years ago, wanting to use a similar setup for a PTO generator. The authorized factory repair center that I contacted said it could be done without much trouble. The info they gave me was "tractors and industrial applications use the same Roosa pump as automotive applications, the differences are in setup."

Sorry TDG, didn't see your response before I added mine!

A Woodward LC50 would work perfect on both setups. Works well on gensets. We have used them on gas, propane, and natural gas along with diesel units. The one for the diesels actually replaces the top of the IP

Thats cool! Do they make it for different Roosa pumps? Who do you contact for info?

I know they made them for CAV and Delphi's. I think they do for Roosa. If not hook on to the throttle shaft with a linkage. It would be the way to go to get a constant stable rpm for generating electricity.

Barber-Coleman makes one like what you mentioned coal bucket, I've heard they work well. But they are a much more involved swap than a woodward governor.

How precise or a speed do you need to maintain Fred? your not running a genset so I would imagine a little bit of wandering would be acceptable. Why not just use a 'tractor style' throttle lever that you can lock close to the RPM you want? The pumps governor is designed to respond to load changes and should be able to maintain speeds fairly well.

I'm just plotting and planning for the future. I have a PTO genset that mounts on a 3pt. (tractor), with standard 540 rpm pto shaft. The gear drive housing is readily changeable as to final rpm. I was dreaming of hooking it to a 5.7 that I just happen to have available. (about 12 spare, running cores plus two daily driven cars) I wanted to use the stock Roosa IP and set it up for constant rpm (somewhere around 1800 rpm would be the easiest to achieve) and variable load. Just thinking at this time. Thanks for the info. Fred

How many watts is the genset rated for? Need to know inorder to determine the hp load for engine. If it is only say 20-30 kw you should be able to just adjust the idle screw to set rpm just allow a little over the rated speed to allow for droop in the gov.
