What is the proper lube for the gear box on snow blower,I took mine apart last night to clean it out and check every thing ,It had a thick long fiber grease in it that looked quite cruddy and was just laying in the corners not doing anything. 

what should I refill this with? I was going to use grease but I see no way that it would get into the one bearing that is in blind hole behind bevel gear.I think gear lube would run out and there is no check hole to check it if I would want to only a fill plug on the bottom of the side cover.

My idea is to pack the bearings with wheel bearing grease and then jam some in the gear case for the bevel gears before putting on the cover.

Ant other Ideas out there would be most welcome----------Thanks Bill

D not use grease in them. Plain old 80/90 weight gear oil. You will have to fill it to the top of the fill plug. There is a gasket on the back and a oil seals that will keep it from leaking.

Thanks BHTS I should have read the manual but when I took the cover off seeing the grease gave me a brain cramp thinking that maybe Bolens had a different idea,After reading your post I thought for few seconds and remebered thats what I put in all my snow blowers.Someone must have packed it with grease sometime in the past 30 years,maybe bad seals? will check them and if bad off to napa.

Also thank you DR Bolens no synthetic,

I don't want to start a fire storm here but I myself am not sold on synthetics yet,they may have there place but it not in my garage.

Thanks guys,Bill

Yes, the synthetics are great for the "New" machines but were never designed or meant to run in our older equipment. It will actually eat away some of the brass parts in the trannys!

QFT!

Not only that, but you have to be careful wiwith just 'plain ole' 90 wt oil as well.

Make sure that you get the older GL4 spec oil rather than the newer GL5 spec.

 

GL5 contains additives that do not play nice with the yellow metals.
