Message: <blockquote data-quote="terryt" data-source="post: 66492" data-attributes="member: 9276"><p>Recently acquired a Bobcat M600 for my wife on the cheap which features major engine trouble (busted rod). The unit is (was) powered by a Wisconsin VH4D engine. In order to remove the engine for repair, it appears that the variable speed drive sheave needs to be removed from the engine. I am in posession of that really bad copy of an old M600 factory manual that is being peddled all over the internet for 5 to 20 bucks but the illustrations of various sheaves employed on these machines appear to be entirely different than what is installed on mine. Makes me feel real special. The hyd. hose on mine screws at 90 degrees into a pipe threaded hole on the side of a swivel boss that protrudes from the end of the sheave. The swivel extends through what appears to be a large thick round washer covering the outer end of the sheave and the swivel is held in place by an internal snap ring. I was able to remove the snap ring and the swivel/fluid inlet assembly leaving a hole in the end of the outer sheave where it was mounted. Beyond this, there appears to no means for further disassembly. The large washer/end cover remains in place on the end of the outer sheave hub which can be turned independently of the outer sheave half but cannot be pried off, tapped off or removed by any reasonable effort I have applied. There appears to be no means of gripping it or even employing a little more axial persuasion with a slide hammer. The manual, at this point, describes just sliding off the outer sheave but nothing budges with reasonable effort and there are no other snap rings or fasteners visible. Before I began this disassembly attempt, I loosened the belt as described in the manual by pulling up on it and releasing the sheave with the speed control. I have been advised that these sheaves are somewhat pricey and really do not wish to attempt to go further until I have some idea what I am doing. Anybody out there recognize this description or successfully remove one of these on a 600 or maybe even a 610 while rendering it suitable for reuse afterward? This really hurts my pride as I was a heavy mechanic for 25 years but this concoction has me stumped. I do know how to get this thing off but it really wouldn't be pretty. My apologies, I would post a few photos and forgo 90% of this long boring monologue but I do not see that capability here. If you reply please type slowly, I am old and my vision is bad.</p></blockquote><p></p>
