1920 Transmission Sluggish or slipping?

[theghoul]

Hey guys,

Love this forum. I've gotten a lot of good advice.

I have a problem with my 1991 1920 SSS. I was moving some snow with a backblade and it piled up pretty high. The tractor started jumping or lunging forward a few times. I lifted the blade and pulled forward and I noticed that the pick up and go I had, got up and left.

The engine is revving fine, but it takes more to move it forward or reverse. All the fluids are good and none of trouble indicators are on.

I let it sit for an hour, went back to drive it and its the same.

If I'm going up hill at the lowest idle point, the tractor will hesitate for about 5-10 seconds, then it will slowly creep up and gain speed.

Before this happened, I could climb this hill at the lowest idle point by just releasing the clutch on 1st gear.

Note, it is about 21 F outside.

Is my trans dying?

Thanks

Is this the 4speed/2range hydraulic shuttle with 2 stage clutch?
Do you have clutch free play? If not the clutch, it does sound like the shuttle. How many hours? Are you the original owner, or know the history? Keep us posted, thanks. Those of us with the shuttle are interested!

It sounds like your clutch is slipping. Check your freeplay. You may have to have the clutch replaced.

Its the 4speed/2ranger.

I have 1700 hrs on it. 2nd Owner.

I'll check that freeplay.

How bad is the shuttle repair?

I imagine the shuttle is expensive to tear into. I'd certainly warm up and drain the hydraulic fluid and change filter before giving up, though. First be sure all linkages are set correctly.

Yaay! That did it! I staved off the NH dealer for a little while longer.

The clutch pedal free play went to 3/4" to 0. Not sure how that happened?

I adjusted it back and power has been restored. I guess it was in "riding the clutch" mode.

Funny thing is I adjusted it last year. Maybe the clutch is starting to get worse.

My PTO is still stuck, but I have yet to take off the FEL and mounts to adjust it through the hole in the housing. That would be my last shot before carting it to the dealer. Replacing the clutch will be a little more than a first timer like myself can handle. I'd like to try though.

Thanks guys!
(ignore the pic with just the cotter pin holding the linkage on it. I wanted to test the clutch before putting the washer and a new pin back on it.)

1920's don't have the hydraulic shuttle option.

The SSS he mentioned fooled me I guess. Wonder what that is?

You may need to adjust your operating technique. If you are keeping the engine reved up going from forward to reverse this can cause excissive wear.Let the rpm's come down some when shifting. Maby use a lower gear.glad you got it fixed.
