42' snow-blower question

Recommended Posts

roma3112
hi all had 2 quick questions for the masses, i am in the process of going through my 42 blower before snow hits us here in boston, and i noticed that the chain that drives the auger has alot of slop in it, i measured the slack and its not quite enough to remove 1 link and fix it. Is there such a thing as a 1/2 link to tighten things up or should i replace the chain. The second question (one which has been asked i think) is what do you all reccomend putting in the chute to help prevent clogs. I have the whole thing painted nice and smooth, would you guys reccomend any kind of spray or chemical to help keep the snow blowing? thanks john

I assume that you have already used the complete adjustment range available on the sliding rear drive gear. If the chain has stretched that much, you should probably replace the whole chain. An ag/farm supply store should be able to provide you with bulk #40 chain and repair links (both full and half). The chain comes in 10 feet lengths (about $10-12 the last time I got some). A selection of links would be something like $5. Carl

John I have worn out four blowers and have never really had a chain stretch much. The biggest reason for slop in the chain is worn sprockets and loose auger bearings. You do not want to run this chain to tight as it will wear the spockets faster and put unnecessary side pressure on the auger bearings. The adjustment for the chain is in the mounting bolts for the cross shaft from the drivebelt pulley to the small chain sprocket. Loosen the two bolts in each end and slide back an equal amount making sure the sprocket is running square and true, with about 1/4" of slack or droop in the top side of the chain. Anything free is worth what you pay for it This & $1.00 might get you a small Coffee Maynard aka/UCD

thanks carl/ucd Actually i had no idea there was an adjustment for the lower chain sproket, i just replaced the auger bearings yesterday and i noticed all the slop, so much so that it has pur a grove 1/2 way through the stud for the chain cover. I will head out later on and try that adjustment. thanks all

I have an 80" blower that I use on the back off my Farmall 460 tractor. As far as the chute I haven't found anything that last for keeping snow from sticking. But for the impellers I bolted a piece of 3/16" thick teflon. It's a bit expensive but for something as small as snowblower props it isn't too bad. Check with a machine shop or industrial supply store. Works good for me Stan

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
