Wish we had a clutch....

[AVIVIII]

There must be another option. My old Hyster H50 forklift from the late 1950s has an electric clutch that is engaged by a microswitch on the parking brake, which is about all I know about the system as it hasn't broken yet (knock on wood). It also has a manual clutch/brake pedal, so that probably plays a part in the system too, but there is notably less load on the engine when the brake is set / clutch is disengaged. You can still use the vertical, tilt, and steer controls when the parking brake is set, so its not a complete disconnect, but it does share a hydraulic reservoir for whatever its worth.

Just wondering what motor oil are you running.....I realize your concern with the hydro pumps

It is probably a automatic transmission with a solenoid that puts it into "neutral" when the parking brake is on. That is how the forklifts at work are setup anyway.

Pardon my ignorance of your machine, but if it has a choke, have you checked to see that it closes completely? A number of cold weather users have found they get insufficient low speed jet flow and the choke not being completely closed. When readjusted, its a 3 second start.

Any of these clutches would go nicely with those cute little PTs. As a bonus, you can carry a few tools in them :wink:

Well, I found my bolt circle. It's 7.75". So I searched for 7.75" circle clutch. Guess what came up first? :laughing:

something like this, but it's all discontinued

Looking at my engine-mount-pto pumps picture below:



I think the pump mount is mounted to the engine on the 7.75" bolt circle.
Then there's some coupling inside there (lovejoy or shaft? I do not know).
Then there's an SAE (number unknown) two-bolt mount that the pump mounts to.

I've not found any clutches that'll mount to the 5.625" or 7.75" bolt circles on this engine (if that is in fact the correct bolt circles, just using what I found so may not be correct, so don't go doing any research based on those numbers yet).

I have found clutches that will mount on SAE 2-bolt mounts.

That would add about 5-6 inches to the length of that installation, and won't fit.

However, if I could find a clutch that bolted directly to the engine an had an SAE 2-bolt mount on the other end, well, it appears that would be about the same length as the pump mount that's in there now.

Hmmmmm..... I wish I could find more specs on that Kohler mechanical pump assembly listed in the maintenance manual for reference.

Well if you all don't find an easy way to de/couple, maybe a multi grade synthetic hydro oil that meets spec for your machine might make life better:thumbsup:

Lot of work pumping Aunt Jamima when its cold out.
