modify a 359 snowblower gear case for a 855
Post a Followup
||I'm mounting a 359 snowblower off of a 650 onto my 855. I've got everything mounted and running BUT the blower/auger is reversed. Parts diagrams indicate that some of the 359's have an idler gear (I assume the 650 mid-pto must run opposite of the 855). However some 359's have the same part #'s as the 59 blowers with the exception of a larger helical gear input and without the idler. Has anyone tried removing the idler gear and changing the helical input gear to reverse the output direction?
||FYI after studying the TM, parts, and both the 359 and the 59 OP manuals I decided to try removing the 19T idler gear (altogether) and replacing the 15T input gear with a 19T input gear. The idler gear roller bearings (pressed in) were just left in place. Runs like a top, in the reverse direction (output shaft now running opposite to the input shaft.) The whole gearbox has to be re-oriented on the blower to accommodate the the 855 hitch assembly (as alluded to in the 359/59 manuals). The 19T input gear (p/n M86075) costs $150, as opposed to $1380 for new gearbox.
