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 with minus screw driver.

It took time, but the result was not bad.

Paste the JB weld in the piston hole.

And screw in the cut bolt with minus screw driver.

Then, grind the bolt and piston with the grinding stone.

Using power drill,

Grind, grind, grind….

It took longer time than I expected to make the piston and bolt becoming flat. Steel is much harder than solder.

I reassembled the clutch master cylinder right away.

I believe finally the overhaul of my clutch master cylinder has finished!

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....

Fuel tank repair: Day 1 --- new mission started!

I ’ ve started the new mission that the repair of rust fuel tank. The replacement of the rear bearing at the rear axle was still on the way , however , during summer holiday I could secure a longer time , and the hot climate would be good for the chemical reaction of the rust remover and drying the inside of the tank. Therefore , I wanted to repair the fuel tank in summer holiday. The target of the 1st day was to remove the fuel tank from a car and to put the cleaner “ MARINE CLEAN ” into the tank. At first , as a preparation for the tank removal , I removed the equipment in the trunk room , such as the electric fuel pump , battery , which may interfere with the work. Next I removed the fuel sending unit and extracted the gasoline inside the tank with hand pump. Considerable amount of rusty objects came out together with the gasoline. After extracting the gasoline I started to remove the fuel tank. Firstly I removed the screws at t...

Brake master cylinder overhaul #4

I disassembled the brake master cylinder again I repaired on the other day because the behavior of the piston seemed to be not smooth enough. When I removed the piston at the last time , I checked the condition of the rubber and it looked good. Therefore , I reassembled it without replacing the rubber. However , again I disassembled the brake master cylinder ’ s piston and checked its condition carefully in order to reassure myself. I disassembled and cleaned the piston and the spring. The condition of the original rubber was not bad , but I replaced it once with the rubber part of the repair kit. Again , however , I felt that the quality of the rubber parts of the repair kit ( left one ) seemed to be poor…. I also assembled the piston into the cylinder as a trial , however , the tight contacting feeling was not enough. As my conclusion , I judged the condition of the original rubber parts were good enough and decided ...
