Turning problem with HD5-G

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello again everyone! Finally got my outboard bearing issue fixed (see other post) and while doing some brush clearing, have noticed some issues with turning left.  I am new to crawlers, and would appreciate any advice...
I have gone through the manual and have adjusted the main clutch, the steering clutches, the brakes and in general have serviced most everything possible.  What is happening, is when I try and turn left (during forward travel),  I pull the left lever back and the tractor stops...it's like the right track isn't moving...but it seems to pull and work fine traveling straight.  It turns right just fine.  Same symptom in reverse, pull left stick and tractor practically stops.  There are times that there is some turning to the left, but just occasionally and it isn't a strong turn...
If the left steering clutch wasn't releasing, why would the tractor stop when pulling the left lever?  If there was a problem with the right side drive, why does it work fine going straight?
Can someone help me diagnose this issue...trouble shoot the problem? And then, what is the fix?

	Sounds like the Right side is not fully engaged - When pulling either lever the machine will have a tendency to steer to that side going fwd . with a light stab on brake it will turn quicker to that side - Holding the brake down should stop track moving and opposite side should drive track - and machine into a tight turning radius. Check the clutch by pulling both back - then apply brake - release clutch on opposite side - machine should lock one track and drive the other - do it on both sides - should have no movement of machine with clutches pulled back . remove inspection covers and check if throwout bearing is releasing or engaging fully . could be oil soaked clutch plates in which case washing them with diesel or stoddard solvent will be necessary.

	how much initial free movement do you have when pulling back on the levers? I believe it should be 1 1/2 inch.

	Steering clutch free play is 3" The clutch will function correctly with any free play. As Coke says the problem is with your right clutch not engaging.

	Thanks everyone... I adjusted freeplay by the manual...I have also adjusted the primary clutch per the manual... I can understand right steering clutch not engaging completely could cause the turning issue...but why doesn't this affect the straight line operation?? Wouldn't the tractor continually creep to the right when traveling in a straight line? Or when digging or pushing? When I pull only the left lever, the tractor will stop. No engine bogging or loading. I have not tried pulling both levers at the same time as suggested...I will try that next time I run the loader (have it at a friends...was trying to clear some undergrowth for him) Also, what really worries me, is it worked great when I first got the tractor (inherited from my father)...at least the turning part...but I was moving some fill around and I think I got a big rock in the right track...it jumped and jerked and clanged and acted strange...and I naively thought "steel is tougher than a rock"...and kept going... Now I am wondering if I could have caused some damage? But if it was a shaft or gear teeth or something on that side, wouldn't it be an all or nothing condition? As I said, sometimes the right track does move...just doesn't seem to be "strong" movement.

	Was the outboard bearing you replaced on the right side? Which outer bearing? It is possible that your steering clutch is functioning but you are not turning the sprocket under power.

	Hopefully it is only out of ajustment,and that will fix it. But if it does not, I have seen a shaft broke in the final drive cause the same problem you are having.I don't know how many other things could also cause this in a AC. This condition would be in agreement with Dozer's guess of what is going on. In a Cat D6 I have had the shaft in the steering clutch brake and also cause this problem. Your comment that a rock went through the running gear and had a loud pop,it leads me to believe something broke. But I sure hope not,good luck.
