Snowblower Rebuild Model 96-42ST01

Recommended Posts

Last season the blower auger of my single stage blower wedged on a large rock which stopped it dead. The drive belt from the tractor snapped, luckily it didn't hurt the tractor but bent the pulley and shaft on the blower. I went ahead and disassembled the blower, replaced all the shafts, bearings, sprockets, drive chain, pulley and will be adding skids to raise it up so I won't scoop up rocks. Before I put it back into service (a bit behind the curve for this season) I was wondering if anyone has successfully incorporated a centrifugal clutch pulley or other device to protect the drive system if a lock-up does occur. I know shear pins are common on other units but wasn't sure how to incorporate one or what type pin to use.

 

Thanks for any insight, much appreciated

I have to say I wondered why there was no shear pins on my single stage and then after thinking about it, the belt is tensioned by a spring loaded idler so I have to believe that is what Wheel Horse had in mind at least for my model.  The belt will slip.

Yeah, this one has the spring idler also, I guess I may have had too short of a belt installed on it because it sure didn't slip when it jammed. Snapped the band new belt like it was a shoe string, I was lucky it didn't damage the PTO on the engine. I just checked the manual for my unit (which I tracked down and downloaded from this site..) and traced the part number to a 5/8" x 69" belt, so I'll be sure to get that size when I get it spinning again.

You might try loosening up the clutch adjustment on the pto so that it slips before the belt breaks or something gets damaged

one thing ive learned is how important it is to keep the area to be cleaned has to be kept free of foreign objects or bad things happen

So far this winter the chain on mine has been acting as the sacrificial part on the blower.  Have a problem with the area where the idler pulley mounts.  It took a really hard hit and bent the side, twisting a link in the chain and jamming the whole works.  I used a 2"x 3" piece of 1/4" bar and backed up the mounting area after doing some body work.  New chain and everything was working until it broke the hydro belt.   Had about 5-6 "  from the storm that finished up this morning, van stuck in the driveway,  Waiting on UPS.  Got a text from UPS.  "Attempted delivery, unsuccessful, will try again tomorrow."   I SAW YOU DRIVE BY! :banghead:

lae51967, one thing I have learned from this forum about snowblowers is you have to make a choice.  If you are going to use it on gravel, you have to keep it up a couple of inches or be repairing the blower more than you are using it.  One of the solutions I have seen on here is for skids that mount on the sides of the blower.  If one of you reading knows of a link for those skids please list it.

I have been using a plow for most of this season and have more success with that.  However, like everybody else, the snow has now gotten to the point I need to get it up and out of the way.

Craig, AMC Rules has photos of wider shoes welded onto his skids.  If he sees this post I'm sure he will chip in.

I found some skids online (http://www.snowblowerskids.com/) I decided to just buy the longer ones and save some fabrication time (plus I'm not the best at building from scratch). I'll try to get some pics posted of them and how I chose to mount them. I'll look into the clutch adjustment, thanks for the suggestion.  I figured it was worth leaving snow on the paved areas to save damage from the gravel areas. Hopefully I'll get my Massey 14 (not a wheel horse but it is red) going good and use it with a blade to trim up what the blower leaves behind.

U tube the horsefixers snow throwing videos. I took worn out skid shoes and bought some flat steel 2" wide and about 14" long. Welded it to the old shoes. I heated and hammered the tips on some round pipe in a vice. I got the idea when I saw the skis he had on a snowthrower powered by his C-120. I have a gravel driveway at the farm. The snowthrower works great now. I have it set maybe 3/4 of a inch above the ground
