I've got the same buffalo 200 (the 14" I believe) and can't seem to remove the final shaft and gear.

Cheers!
The gears ate held on with tapered drift pins.

Carefully drive them out and then stabilize the shaft while you rotate the gear.. there is a burr that forms internally..

Also, in the last photo, it seems there is the making of a small crack along where the "set screw" (for lack of a better term) piece is. I don't want to go tapping on the shaft trying to knock it out if the crack is going to widen itself and break the gear.

The whole contraption works as is... but there is a ton of gunk and rust on the bottom that I want to give a very thorough cleaning to before putting it back in service.

Thanks for any help.
I'm a gluten for punishment so I'd probably remove it. The danger will be when it goes back together and you reinstall the pin.

That being said.. if you disassemble the bottom you won't have to touch the top gear and shaft. ..

So Jenn, what RPM are the blades turning with the gear reduction?

It is variable speed. 0-? Depends on how fast you can move your arm..

It's actually a gear increaser vs reducer.. IIRC its 1 = 8 turns.

Okay, I was way off on the ratio.. it is 48:1..

I worked on the blower yesterday and used some of the 6001RS bearings or where they 6000RS..

Anyhow, I need to find real oil seals for this..

With the bearings in there it ran super smooth and actually very quite for having rust pits on the face of the spur gear..

The factory bearing is a Magneto bearing which instead of making you guys look back is 12IDX32mmX7mm

The 6000RS are 12mmX32mmX10mm So either these with real oil seals installed or something

There is an outer lip on the outside which could fit a seal with no hole.. and is 1.625 ID The other side has the same ID but with a 12mm shaft running in it..

So need one blank off plug and one oil seal.. This would make the is blower outstanding as then it could be oil bath of the gears..

On these blowers you would add oil at the start of the day but within 5minutes the oil would be on the floor..

Help please.

I got an idea for the side with without the shaft.

You could make a tap in cap for the one without the shaft. My band saw gear box is not sealed and grease is used instead of oil. I am sure that shade could find some grease that would work. Otherwise one could buy a seal that would fit the shaft and make a cap machined to except the seal and use the three bolt holes in the case to attach.

Interesting idea.. and based on that idea, I think I'll make a cap with an oring on the outside edge.. Problem solved on that side.. Thanks..

The original seals were just felt with a piece of heavy paper board behind it.. Stuffed into a cap that went over the shaft and into the body..

If you read any of the old journals that was one of the biggest thing that was bad mouthed about Champion or Buffalo blowers.. They were oil spewers.. Canedy Otto came with an oil filled blower that was sealed properly and touted it..

So, for years I poundered why would they have an oil fill on top and a level screw at the back side then there is literally no oil in there once in use..

The level screw is about level with the top of the spur gear inside the case. Yet the wiper seal is lower than the shaft? Both leaked anyhow as they were just stamp steel and to fit the case they had a groove cut in..

So the idea of getting a seal and fitting a cover is a good one..



I looked last night and there are no 12mm X 1.625 seals even made from what I found..


Making a seal carrier isn't much of a problem.. I was hoping someone might just happen to know where to find the right sized seal..
