[QUOTE="7LBSSMALLIE, post: 59822, member: 6879"] back in the the day it was cheaper to replace an (ANGLE DRIVE) than to rebuild one now not so much, first belt lenghth on these is somewhat in the air s/n differances make this a make it work rather than this is my model this is my s/n thing, rather embarrisining i think. , so that being said a few facts. sevral changes have been made to both pulley size and belt length, as a genral rule first verify angle drive belt tenninoser spring and arm are good( belt off should snap back with no side to side play) backwards and fowards than verify it is not bottoming out on drive belt spring if it is go with shorter belt or bigger pulley (s/b i dont care # improved cooling etc) what you want is bolt that extends thru angle drive teninsoer arm to be about 1/2 inch off large spring, to reiterate this can be accomplished by a larger pulley or shorter belt.. now a couple of facts always going to be noisy on start up (takes a second to catch up wit eng speed a little knock normal. now to the heart of the matter the angle drive is a simple ring and pinion,! rear end on a smaller scale, take it apart clean it set backlash reseal and reassamble GRAVY parts avail at decent price be sure to ave shim kit, set it up at 2 to 5 backlash good to go, [/QUOTE]
