Does anybody know if the change from the locking collar to the snap rings on the new max IV axles was because of failure in the field (sprockets coming loose, chains coming off, etc) or just pure maintenance convenience? I have had people tell me both. I have read of one failure on here.
Also another question. Rather than heating per the factory to remove the setscrews why dont people just cut the lockrings off with a die grinder?
Thanks,

Bill I think you may have some info mixed up. The lock collars are not on the sprockets. The eccentric lock collar is on the outer bearing, outside the vehicle. It also has a set screw to tighten after the collar is locked, but this is not the problem area. The sprocket assembly on the rear of a Max IV is a 34 and 26 tooth combo. The set screw holding that sprocket in place is between those two sprockets. That little screw is all that holds the sprocket in place. After some run time (even sooner with a bigger engine) the sprocket begins to rock back and forth. Once that happens, the sprocket can slide down the axle and there goes your chains. The new snap ring design eliminates that possibility. A ring is on each side of the sprocket so it couldn't possibly move out of place. The set screw hole was replaced with a grease zerk, to allow you to grease the splines (supposted to increase life even more).
The snap ring update was done mostly to get rid of this problem. It also makes it easier to replace/remove an axle if you ever need to. Some set screws in the old sprockets seize up (like the one recently on this site) and will never come out. I've had Max IVs with set screws barely finger tight or almost welded in were drilling is required. Snap rings are the only way to go. |
