MDT Snow Blower (maybe 5 or 6 hp) has worn out (destroyed) bearing, single speed forward/reverse, two stage.?
on one end of a shaft that that is supported on the side of the gear box (bearing bolted to the left side of gear box (left side as you stand behind snow blower). The bearing is destroyed, caused slop in the shaft and the chain came off (bearing was probably going bad for a long time). Anyway, was this bearing (and other bearings) sealed or should have the bearings been lubercated some how? If so how and with what specific grease, what about chains and ???, should they be lubricated, I don't have any kind of manual, I don't know if anything on this machine as ever been lubricated except for engine oil change, it is probably 20-30 +/- years old. What other maint. is required, what should the bearing cost, any special tips for install (I got it out with great difficulty, had to remove other bearing, remove chain that goes to auger drives from shaft). Where do you buy a bearing like that. Any other helpful information appreciated greatly (accessed gear box by rope supporting handleba
Try a mower shop, small engine parts or industrial bearing supply house.
The easiest way to match up new bearings is by using the number which is stamped on the bearing itself. Since it was destroyed you might need to resort to Plan B.
Plan B is based on using a mfg parts list. This is a pain as the engine is prolly a Briggs or another manufacturer other than MTD.
Chances are the engine’s identifying numbers (model, S/N) were originally stamped on the sheet metal cowling and difficult to read at best when new. Good luck reading them a coupla decades later.
MTD has been bought/sold/reorganized several times over the years and oftentimes is no help when it comes to replacement parts. Every now and then you’ll get lucky and reach an old timer at the factory w/good memory. Failing that your local mower shop or small engine parts can be a Godsend.
Good luck…
Wow, what a project. The bearing wasn’t intended to be greased unless there’s a grease zerk by it. As for replacing it – that could be tough. I live in a rural area and there’s an implement dealer here. There’s a section devoted to bearings and there must be a thousand different ones. Probably won’t have access to a collection like that though in a city. First, you’ll need to get a hold of a caliper and write down the inside, outside, and width measurements of the bad bearing. Then go looking for an identical one. Sometimes machine shops have random size bearings available. Who knows? Maybe MDT still uses that dimension of bearing in some product. But finding someone who would be of help at MDT would probably be the hardest part of the whole project. One place to start on this information quest, is an auto parts store. One that has machining services too. They should have a catalog of bearings along with the dimensions. Remember, these dimensions are in thousandths of an inch. That’s why you need to barrow a caliper.
get the model and serial number off the unit not the engine,go to a web site emerichsalesandservice.com in charlton ny,look in the parts look up system on web page it will give you a blow up on the machine with part numbers,pick out the bearing and part number and call me I ship orig factory parts,most of the time thoes types of bearings are sealed and just wear out.or just email parts dept with your numbers
