Rustyred 58 #1 Posted January 14, 2018 Here's a question regarding the pulleys on my 1979 C-81. As I assemble my tractor I see that the previous owner had the drive pulley located so close to the engine on the shaft - literally touching - that there is a minor groove left in the engine from the spinning drive wheel. What is the distance I should locate the pulley from the engine and then, how do I ensure that the 3 pulleys are aligned correctly? And should I use thread-locker on the two set screws? Thanks again, Rustyred Share this post Link to post Share on other sites
formariz 11,849 #2 Posted January 14, 2018 (edited) It depends on a few factors including where the transmission pulley is also. The best way is to place a straight edge across the face of all pulleys. Straight edge should be touching both edges of all pulleys in question. Now they are aligned. Check to see if they clear everything specially belt guard. If so you should be OK. If not you are going to have to move all pulleys in or out to achieve clearance. Pulley at engine probably got loose and moved inwards towards engine. That is known to happen. Make sure that set screws are tight once alignment is finished. Its a good idea to check that occasionally specially after extreme temperature changes. Here is an example on something else but same principle: Edited January 14, 2018 by formariz 4 2 Share this post Link to post Share on other sites

Will be close to the block but not touching. What is the distance I should locate the pulley from the engine and then, how do I ensure that the 3 pulleys are aligned correctly? As stated above by @formariz And should I use thread-locker on the two set screws? Yes, I always use the blue. Thanks again, Rustyred 1 1 Share this post Link to post Share on other sites
