Hydro question
 

My trunion has two corners worn pretty bad. Will this cause the hydro lever to be unresponsive for most of its travel in both forward and reverse? There is quite a bit of side to side slack in both plates and the end of the rod that rides in the groove has two flat spots on the end but I can not see any obvious ware in the groove.

When you watch the linkage move the first plate moves immediately but the second hardly at all then it rocks forward all of a sudden. That's basically what I have to do when mowing is rocket forward and then back it down to an acceptable speed. If you push the lever forward a few inches and leave it it almost like you were riding the clutch really bad the way it builds up speed then you have to back it down to set your speed. Is this all related to the trunion?

Yes, to all questions. :ThumbsUp:

Yes, that amount of wear will not allow smooth action. Weld up those corners and square it off. I'd have a look at the end caps on the spring for possible replacement.

Jonathan in this picture the plate marked with the arrow on my tractor seems to have a lot of slop in it...side to side slop is this normal for this or is it worn and needs attention?

Simply remove the snap ring, add an appropriately thick washer to take up the slack, and put the snap ring back on. Fairly common thing to do. :beerchug:

Ok sounds cool it flops around pretty much so I will see how much shimming I need and give it a try!

This is my stock answer for trunnion problems.

If you have or suspect that you have trunnion problems with your Cub Cadet hydro, start by going here.

There is a lot of good debate here.

After you have fixed your trunnion your forward-reverse lever and foot pedal may be out of wack, so go here.

Personally, I see no need to add extra metal pieces to the square hole, unless the ends are worn crooked. I have never had this problem with any that I have fixed. So I simply weld the slots in the corners and then file them back square again.

I think someone said one of my links is dead, I don't know for sure, haven't checked them in awhile.

All good info Sam...I was talking to Jonathan about this and over the weekend I was messing around and my trunnion isn't worn like I have seen them, but none the less I still have that speed lurching at the most inopprotune times LOL!!!

If the only problem is that the lever is creeping or even quickly moving itself in the direction of travel, that could quite possibly be just an adjustment (depending on the machine that you have). If you have an early style Wide Frame, the plastic bushing at the bottom of the forward/reverse speed control shaft could be worn out and need to be replaced and then adjusted.

I will look into that this weekend, I have a late '74 149, just to many things to do and not enough time. I need to get it looked at before I kill myself this winter :bash2:
