PS: hmmm, maybe not--just refreshed my memory with some pics--cam bearings are not blind...

Maybe tailshaft bushing tools? Or something along those lines? How bad are the bushings? Is a little slop OK?

Is here gear oil in the casing or just smeared grease on the gears for reassembly?

An expanding mandrel that can grab the inside of the race which is basically just a hardened piece of angle iron not unlike a bicycle style bearing.. If you look at the pictures closely you will see the housing is higher than the bearing.. Looks like it was not designed to be fixed..

Same deal as mentioned.. Problem is there is nothing to grab onto.. And expanding mandrel would be best.. Not exactly sure of the size yet.. I will measure in the next few days..

There is gear oil in the case.. Well.. Back in the day it was any oil or bacon fat or any other item they had on hand..

I'll use some Mobil DT Heavy.. I'll also work on sealing up the box so it doesn't leak oil as heavily..

So made pretty good progress again today..

Got the handle/drive shaft thrust bearing installed.. It is just a ball bearing locked into the end of the shaft..

This rides against a threaded rod with lock nut on the other side with the same bearing installed.. The to rubbing together is the bearing surface.. Works pretty well..

The next thing was to make the new intermediate shaft thrust locator and new intermediate shaft.. Shaft was easy as it's just 1/2" cold rolled cut to length..

The intermediate thrush locater on the other hand was probably the most complex piece I have ever made with the off center hold..

This is screwed in until it locates the intermediate gear at the correct clearance for the pinion gear..

The input gear is located but the position of the gear on the shaft and is only adjustable by adding a shim to the handle side and moving the thrust bearing outwards.. Only adjustment is in and out..


The intermediate shaft has 360 D adjustment for correct gear mesh and correct gear clearance as well as left or right int he housing..

The bottom pinion is also held in place by the thrust bearing on the outside bearing block but only for thrust same as the input handle/shaft..


So I still need to add the 2 small pin holes to make rotating the intermediate 360 adjusters easier.. I also added a 1/2" threaded hole to one side so I can add a thrust bearing here also though the intermediate shaft does not turn.. Its more for oil control..

This thing reminds me of a 2stroke diesel... Oil everywhere and you can't kill it..

I shot some video of just moving the gears by hand and so far I am very excited.. It sounds gear even with no bearings on the output shaft..

Few more days and it will be done.. I'll try to locate a pinion bearing next..

One other factor about this blower the output shaft actually has an oil hole to pick up slung oil to feed the shaft..

Here is the inside with the intermediate shaft in place with the new parts..

Also a picture of the old one..

The puller I made removes the bearing using the inside race.

Sorry there is no inside race.. only thing left is the bearings outside race which is still stuck in the housing..

The expanding idea is brilliant.. But there is not really anyway to grab it..

here is a picture again of the race inside the housing...

The little booger way down in there? I still say some weld to shrink it or the Nuclear solution. I will preface this by saying I am not a huge fan of this method it either works or FUBARS shit in a hurry. Take a small OXY/ACT welding tip and heat a slice/section of the race to cutting temp ( For me when sparks start to fly) when you have it to temp cut the fuel and crank open the Oxygen as the race melts/ blows away chase it down to the dark division between the race and the housing don't tary and don't use a good welding tip.

I think I will try to hit it with the tig torch.. I have a long lens so should be able to get down in there..

My skill set isn't good enough to get in there with an A/O torch.. I'd be afraid to gouge out the housing.

The bearing is junk so no matter what I have to replace it..

anybody know where I can find a cone and cup bearing?
