Cust brought 656 in for different repairs and said tractor stopped ONCE (1 time only) in TA. I have tried to but can't get tractor to slip/stop by riding brakes and repeated shifting. The guy will "hold still" for a TA job$$$ but my conscience tells me tractor is OK. In 40+ yrs I've never screwed anyone that didn't have it coming!lol Is the TA out?

Did you try to make it act up before or after you have worked on it ? Reason for asking is if the clutch and TA adjustments are off it could possibly act like that and afterwards not act that way. Meaning that maybe the slipping the customer talked about was just things out of adjustment.

The TA probably did slip, when the worn parts of the ramp and rollers lined up just right. It will eventually start doing it more often until ultimately it won't hold in TA at all.
Should the TA side go out, he can still run in direct indefinitely. These mechanical TAs rarely go out on the direct side unless they are BADLY out of adjustment for a long time.
The question is, how long does it have? It could run for years. It could fail tomorrow.
Personally, I would recommend to the customer that unless he ABSOLUTELY wants to dump the money into a TA job now, he should just continue to run it normally until such time as the TA no longer functions.

One other thing that might cause slippage is heavy gear oil in the rear end. Odds are since the tractor is using the transmission lubrication fluid for the hydraulics and those are necessary for power steering if nothing else, it isn't filled with heavy gear oil.
Respectfully, though, I am pretty sure that there is no adjustment you can make to a perfectly good mechanical TA that would cause it to slip.

It might last for years and it may last a week. Here is what I used to do on those if they were questionable. I take that little cover off, block clutch pedal down, then tap lightly on the 7 inch clutch pressure plate with a hammer handle. If it is really in good shape you will not be able to make it go back wards. (should have said tap toward opposite way it normally turns). If it goes back wards once in a while it is probably not going to last very long.
I never had much faith in making them slip with the brakes, but pulling it back and letting tractor free wheel while moving at a good speed will also often times show up a bad ta. Works even better on the larger tractors with hydraulic ta's while pulling lever to middle position and letting them free wheel as they slow down they will some times slip if going bad. Very first 806 that I repaired the ta on would only slip on rare occasion and that is how I got it to act up. Tractor was only a couple years old.

Like Pete said and i might add here it's WINTER TIME and even with Hytran with everything COLD she could have hug once . Myself i would tell him to run it and see how it goes , he may get a week , he may get years out if it . My own first tractor with a T/A did not like winter and at times slip till she warmed up and never miss a beat after .
