I am pretty sure that the problem is not slippage because of oil. I seem to have an inordinate amount of play in my pedals. using all the spacers, deck belt is adjusted properly (1 inch between pulleys) but it is slipping as bad as before I changed the worn out yoke. Maybe the liner is bad? Looks OK. did not have the problem until I changed the drive wheel with brand new one from dealer. Will put old one back on. Any other suggestions? OK, thats not it , put the new one back on. If I press down on the yoke,it grabs.I do not understand. Seems like it is not engaging fully. I dont want to take it to the dealer. Help!!
