Do not adjust this bolt adjustemet. It is usually not the problem and if you adjust it you may never get it adjusted correctly.
The problem is usually the reverse disc that is worn out.
Replace the reverse disck
240-398 is the stens aftermarket number.
he Troy-bilt number is XXXXX
these part numbers are assuming that the drive disc lining is a rubber drive disk. the much older units used a Fibre drive disc of a different part number.
Sorry, the Correct Troy-Bilt part number is XXXXX
Do I need a pulley puller to get it off? There is no room there, does the entire engine need to be removed? Is there an available manual and parts list and diagram? Thanks
Hi, I am still waiting for a response on how to take it off or get a repair manual.
The drive disc is held on with one bolt. then it should come off easily or if not then just a few light taps with a hammer should get it loose.
Here is a parts manual Go to page 20 and you will see the reverse disc. http://www.mymowerparts.com/pdf/Troy_Bilt_Troy_Built_Service_Repair_Manuals/Troy_Bilt_Horse_Master_Parts_Catalog.pdf
There are two large pins that hold the engine onto the frame. there is a bolt in the side of each of these. usually you only have to take one pin out by loosening that one bolt on the side. then take a punch and punch the large pin through the botton to remove it. Then the engine will rotate on the other pin so you can get to the reverse disc. Many times you have to work the belt off before the engine will rotate far enough to get to the reverse disc.
One you are that far, then you should be able to remove the bolt that is holding the reverse disc in place and then tap it off. Replace the disc and you should be done. Then put it back to gether. It is ALWAYs a very good idea to replace the blet while you have it off.
Great! Thanks for your help.
