How would I check for the worn bearings? Are those the ones I just shimmed from the back? How much movement tolerance is to be expected around the rods? There is some movement in these areas.

jhngardner367

The rods should be a slip fit,and very little movement side to side.keep them clean/greased. As for the bearings,grab the pulley and try to move it sideways/up/down. ANY movement,other than in/out is bad. In/out move ment should not exceed .010.

If there is excessive plays around the rods, how do I repair that?

jhngardner367

If the wear is on the rods(you'll see the wear)replace them.If the wear is on the slider block,you'll have to have them reamed,and some bushings fitted,or replace the slider block(NOT CHEAP!).

What is the Troy Bilt tolerance between the rods & the sliders? How would I check for excessive movement between them?

jhngardner367

As I said,thy are a slip fit.If theres any sloppiness,refit them,with new pins,and/or bushings. If you can actually seeany tilting,or sideplay,when the slider block moves during forward/reverse engagement,then they are worn.

I'm going out now to see how much slop there is in the system. How do you normally repair tillers that have this condition? Where can I get the rods?

DaveCraw

No slop in the rods when shifting from forward to reverse. You mentioned earlier that the rods should be greased. Guess I have mis-read the owners manual all these years 'cause I've always been using oil on them. Do you feel that grease works better? Could all my premature disc wear been solely from the exceesive main shaft slop?

Answers???

Sorry Dave didn't mean to leave ya hanging.The rods are available through troy-bilt.As for bushings,you would have to get the rods,and go to an auto parts store that sells bronze bushings,and check them for fit.Then,have the holes in the block reamed for a press-fit to the outside diameter of the bushings.It's not difficult,if you have a drill-press,and get the right size reamer.I've done 3 of them,over the years,and I also drill a hole, to fit grease fittings,in them. It's always possible that these problems can be caused by looseness,in the parts.One of the reasons they changed to the rubber-rimmed disc,is that it's more "forgiving",and it also grabs the pulley surface better,so you get better drive.

Excessive slop in any of the parts,can cause problems.I've seen them so loose in the shaft bearings,that it jammed the gears,and broke the casings!Lube types are up to you.If you feel that the manuals' method is good,and it hasn't worn,keep doing it that way!I put the grease fittings in, at the customer's request,because he didn't want to have to keep oiling them.Whether it was better,or not...?

Thanks again for all your help & info!! I'm going to clean the rods up real good & then grease them per the owners manual; I don't know how I went from grease to oil 'cause I'm usually pretty fussy about following manufacturer's service recommendations.

DaveCraw

Looking back on all your correspondence, ther is one question you did not give a real solid answer to. Could the excessive main shaft play been the whole cause of the premature disc wear? Can you give me any more things to check that might contribute to my problem?

jhngardner367

Just got on site a few minutes ago. Yes,the excessive mainshaft play could contribute to the wear you've described.It causes the disc to hit more to the sides,than center,and in exteme cases,can shatter the disc,completely.It can also cause accellerated wear on the gears,especially if the gearlube is low,for any length of time. As far as I know,the things I've told you are about all that would account for the problem,except for a defective disc.
