moe1965 738 #1 Posted June 11 I'm currently working on an 857 the drive belt calls for a 70 inch by half inch belt which is on the machine now it is a brand new belt it still seems to be quite sloppy first gear catches ok but 2 and third the belt slips and that takes off. I wonder if previous owner changed any of the pulleys the drive pulley is 4 inches across and the pulley on the engine is 2 1/2 in across the. Thanks in advance Share this post Link to post Share on other sites
rjg854 11,361 #2 Posted June 11 My first thought is what shape is the return spring in? Is it stretched out? Hooked up right? Share this post Link to post Share on other sites
squonk 41,118 #3 Posted June 11 (edited) 1/2" X 70" is correct. What is you belt # ? If you got an A70 that belt is actually 72" long. I have an 857 and the belt that's on it is a 4L700 Edited June 11 by squonk 2 Share this post Link to post Share on other sites
