Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a gnashing noise when I engage the auger on my snowthrower. All the belts and pulleys are adjusted properly.The pulleys and sheaves are running true and are secure on their shafts. All the tensions are correct. The gearbox is filled with 90wt.hypoid to the proper level. The auger is properly greased and free on it's shaft and the shear pins are the correct ones for the machine.They are not grooved and are torqued to 11ft.lbs as called for in the manual.The brake arm is adjusted to 1/4" clearance with the handle depressed as called for in the manual.There is about 1/32" lash in the auger which seems to be normal for this kind of set up. I drained the gearbolx and poured the oil in front of a flashlight and found no metal fillings so I assume the gears are ok.The machine has about ten hours on it and and has made the noise from new.

The unit is a TroyBilt 42010 .It is the last of the Gardenway produced machines before MTD bought the name.I bought it at a deep discount in a crate in 1997 and used it for the first time last year. I did the assembly myself according to the assembly manual and no short cuts were taken.The noise has been present ever since the first use. The machine works flawlessly but the noise bothers me as I am afraid something is amiss. Any suggestions?

MM14: Take off belt guard. start motor and let it idle. BE CAREFUL!!!. Engage auger belt slowly. Look very carefully!!! Does anything move slightly forward or backward? Shaft moving foreward or backward? Impellor moving foreward or backward? Check inside of impellor housing, does it look like metal scraping metal. Piece in the shaft that set screw tightens against too far in or out and is rubbing against belt guard? Recheck all adjustments, maybe something slipped during assembly? Roll pin slightly bent? Sheet metal straight?

Am running out of swag (silly wild a$$ guesses) Hope you find out soon!!

Spent the day disassembling /reassembling my blower. No bent roll pins or areas where rotating parts are rubbing.Before taking the machine apart I did take off the belt housing cover and looked for the problem with the engine running.Nothing is moving back and forth,all of the bearings pass inspection and the alignment of all the blades seems to be ok.

The bad news is that after taking a whole lot of time and care tearing it down and putting it back together the noise is still there! The good news is I am now fully familiar with my machine.

Either the problem will become worse and the cause more obvious or I'm just going to have to learn to live with that noise.

Thanks to all for the effort on my behalf,

I wouldn't worry about it anymore, sounds like it's just is a part of it.

Robert I was because of the PIC problem you were having, you have since figured it out.
