I posted some of this on the old forum but never got around to working on the blower.

A friend gave me his 1978 Bolens snowblower . It has not been running in 5 or so years. He told me the motor, augers and drive were working but he stopped using it because the impeller was "clanking around in the housing"

I am guessing the problem is whith the impeller bearing?


I contacted MTD about getting a manual/parts guide. I was told they dont have one. any body have any ideas on how to get one?


I am guessing this is a 7hp 26inch cut based on the model #. I will have to check the engine model # since my friend told me it was replaced in the late 80s early 90s. with a new tecumseh snow king. He let the oil go down and threw a rod through the original motor :(


I figure I will try to get the motor going first and if that works then look at the bearing


if I do get the engine running what war the steps to replace a bearing or how would I even tell if thats the problem?


I'll post again as soon as I find out if the motor will run





:lol:

John,

Pictures might help someone that knows.

I would take the auger belt loose or off and try to see how much the impeller moves up and down. I have no idea what would control the thrust. But shaking stuff around to see what seems to move too much might be a place to start. At least then you could tell folks what you found. Also when you take the belt off you might find a pulley or belt that might have been making the racket.

I finally had time to get this machine over to my house. It looks in OK? shape. I think it was a good machine in its day. (heavy duty with grease fitting etc.)

I fixed the pull start it was just rusted a bit
I put in gas cranked the electric start and it turned over ! :lol: So the motor is still good. although it runs with a lot of vibration so i think it need carb adjustment.


the tires were flat but they just needed air. so that was good.


Now here are some strange things. The control panel on the handle bars has levers to engage auger , control the speeds and the the shoot.

and the handle bar has just one lever . Here is the strange part, with the engine running and the drive lever set to any gear except "N" the blower moves until you squeeze the handle then it stops????

In other words squeezing the handle LIFTS the friction wheel off the platter??? this is the opposite of any other blower I have seen. any ideas on why it works this way???

MOving on to the impeller bearing it looks like it is shot ! you can move the impeller shaft up and down and if you engage it while the motor is running it clanks around in the housing, I think it can be repaired . I will probably have to tackle that in the spring as I have no garage to work in :(

I think it is worth saving . I have to put it on the back burner right now while I try to get my "good" blower running. It has a spark issue I am addressing on another post.

I will keep you informed as I continue on this one.

Yeah the reversed clutch is just like my old Hahn-Eclipse Snow Giant from the 60's-70's. Safety wasn't a concern in that design apparantly but it works well as long as you remember to use the clutch when shifting and put it in nuetral when don't want it to move. Good luck on your restoration.

Wow thats how it is designed to work! :shock: Lets hope I dont fall down in front of it. It moves by itself and the augers stay on as well !
