Message: <blockquote data-quote="tima" data-source="post: 7949" data-attributes="member: 880"><p>Are you sure the sheave is actually frozen. See if you can get some slack in the drive belt by pulling up on it. This should make the driven pulley open up, then you can wedge a 2x4 between the loader side and the drive pulley and see if it will compress. When you move the speed control all the way forward does the engine show a little speed change as if you are getting hyd pressure to the sheave. If not you probably have something wrong in the spool valve. I rebuilt my sheave with a seal kit but still could not get it to close all the way at full throttle. When i received the service manual i found out that there was a closing and holding pressure adjustment on the spool valve. Made the adjustments and everything works great. By the way my sheave was not frozen , it just leaked like crazy and would not operate. There is a grease zerk on both sheaves and if you do not have a hyd problem maybe a little grease will do wonders. If you need to rebuild the hyd portion of the sheave it is pretty simple. The only problem with mine was it was severly pitted in the bore , but after about 2 hours of honing it was like brand new. In either case a service and parts manual is a neccesity. If i did not mention it before i did get mine from my local dealer and they were 1/2 of what the fellow on Ebay wants. What a surprize. After replacing several bearings,hyd lines,rebuilding tilt cylinder,bearings and seals on 1 rear drive axle and some other cobble-ups mine is almost like brand new. Still need to change all the hyd hoses though. No leaks but they are looking pretty ratty. I just can not stand to see a machine look like a peice of junk. I have used it to remove 5 stumps and grade the driveway a couple of times and i am very pleased. I think my propane vaporizer needs a little attention next. Wants to die after dropping from full speed load to an idle. Adjusted the main and idle mixtures but it did not make any difference. Need to check outlet pressure at the vaorizer. Anybody out there have any other suggestions???? Good luck and if i can help you out in any other way let me know. Tim Schuldies/Tim's Electric</p></blockquote><p></p>
