![]() ![]() If they had offered it in a six-point version - it might have worked better - but - with only six points I'm not sure there would be enough room for movement with the crawler on the ground. those that had never been apart before - it sometimes worked - and sometimes did not and just stripped the bolt-head. If we're talking about the same wrench - it had a 12 point box end. But, they did not hold up - so we splurged and bought from Snap-On. At first, we cut down John Deere wrenches - made by Bonney or Utica Tool Works - because we got them cheap. Those are the wrenches we adapted and hooked the chain to. I don't remember if it was 1 1/8" or 15/16". We had the Snap-On pipe-handle wrenches in the shop. Re: John Deere 350C transmission in reply to Roy Suomi, 06-04-2006 19:38:01 Maybe someone out there has come up with a better way to do it? In our shop - we tried just about everything - and Deere engineers had no good answers (they rarely did). I mention all this - because it seems the cause of the many bad transmission and reverser cases in 350s is caused by those two bolts never getting tightened properly. We got so, with new machines - we heated them red hot until they stretched and got ruined. ![]() And - to take the bolts out for the first time with a new machine - again - pretty difficult. Even with that, we had trouble getting them tight. We used special short box-wrenches with a chain hooked to the end. So, with a complete and assembled machine - there not very accessible. We were told by Deere engineers - that at the factory - the bolts got tightened with the trans and reverser out of the frame. They are near impossible to tighten properly. I suspect the main culprit is the bottom two bolts that hold the reverser to the trans. If you have a case with worn dowel holes - fix it or don't use it. They tend to get egg shaped after years of being run loose - and when that happens - the trans and reverser get out of line and the splines get ruined on the shafts where the coupler goes. If you plan on swapping cases - be very careful about the dowels and holes where the trans. We took a few and, with a grinder, reshaped the remaining gear stubs so they could be used a little more. So, after years of shifing while moving and clashing gears - they get worn down to a point where they will no longer stay in gear. That because they use sliding-gear transmission - not constant mesh collar shift. They do not shift well on the fly if equipped with a hydraulic reverser.
