Removal of the rear axle hub bearing: Tough job

In these days I was considering about the method of removing the hub bearing from the rear axle.
When I was reading the workshop manual one idea came up.  Today I tried it.

What I prepared were a robust steel bracket (a part of the shelves for heavy items) and a puller.



I cut the bracket with a grinder to fit the holes position of the hub.
Then, I returned the axle shaft to the rear hosing to make the work easier.  The retainer nut for the bearing was already removed.  Therefore, the bearing could be removed by pulling the axle shaft in my thought.

I set the bracket, bolts and puller on the axle shaft and the housing of parking drum brake.  Pulled the axle shaft by puller and pushed the drum brake housing by bracket and bolts.  By tightening the puller, the bearing should be pushed by the drum brake housing, then the bearing should be separated from the axle shaft!!!


But, the bearing could not be removed as a result!!!  The fixing of the bearing was very tight and the bracket was deformed. 


I did some trials with other sturdy materials instead of the deformed bracket, however, the results were same.  I stopped the trial to avoid the damage of the drum brake housing made by cast iron.

I also tried another primitive method: fixed the bearing with a vice and hit the shaft with wooden hammer.  But it didn’t work … I gave up!


I had confidence in this puller method … Hmmm …

Tip to repair rubber parts

I disassembled the rear axle before.  There had been no progress on it because I started the repair of the fuel tank during my summer holiday. While painting the fuel tank , I repaired the torn rubber boot of the parking brake wire. I guessed it didn ’ t cost high because it was small rubber part.  But I wanted to try the repair method I read on the magazine article before. This was the condition before the repair.  The rubber was torn apart and separated almost. I used this self-adhesive type butyl tape.  I pasted lots of small pieces of the butyl tape on the back side of the rubber boot.  As time goes by , these tapes would melt and stick together.  After this I applied plenty of adhesive “ Super X Black ” on the rubber boot.  On the magazine of MOTO MAINTENANCE , I read the article that the motorcycle seat was repaired with this method.  So , I wanted to try it. After drying 1 day , it became like this....

Clutch master cylinder overhaul #5

Regarding the clutch master cylinder which I repaired the hole at piston with solder , one of my friend advised me that the solder might not be hard enough.  Therefore , I tried the repair again in another way. Disassembled the clutch master cylinder again. Now I can do it very quickly because I disassembled brake master and clutch master cylinders many times J Heated and removed the solder at the piston hole. I used the soldering iron instead of the burner because I heard giving too much heat on piston should be avoided. In this time , according to the advice from my friend , the repair method is to screw in the thread with strong adhesive into the hole , then grind the thread head to make the piston surface flat.  In order to do it I bought bolts and a grinding stone at the hardware store. Cutting the bolt to adjust the length to fit the hole depth.  Engrave the minus groove at the cut bolt head to make screwing in possible ...
