Fuel leakage from WEBER

Last time when I did the maintenance of WEBER, I found fuel leakage from the fuel hose connected to WEBER.

I recognized that the gaskets of the fuel union had to be replaced.

I bought a gasket sheet with 0.8mm thickness at a motorcycle part store. I guess it is cheaper if I order it at automobile part wholesaler. But I bought it at motorcycle part store because I wanted to get it quickly. I found there are lots of parts, which can be utilized for a historic car repair, in a motorcycle part store. ☺︎

I copied the gasket shape on the gasket sheet and cut out them with a cutter, but to cut out the rounded shape was little difficult. It took more time than I expected. I should buy a circle cutter in next time.

The appearance was not very good, but it should be no problem functionally. And it would be invisible after the installation.

After the installation I activated the electrical fuel pump and confirmed that the fuel leakage from the fuel union was fixed.

One other small repair. I found the wire harness for the water temperature sensor was degraded. When I touched it for replacement, it was broken.

I replaced the connector with new one and added the reinforcement with heat shrinkable tube.

Now it should be no problem!

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 #3

I was still struggling with the sticking piston of the clutch master cylinder. I thought I should give up and look for the new part for the replacement. And to for my curiosity , I started to destroy and disassemble the clutch master cylinder piston by drilling. When I was drilling the piston halfway , I didn ’ t have any specific idea , however , I thought to tap the piston to make the thread. I started to turn the tap handle , and I felt the feeling that the piston was moved. So , I tried to pull it , and then suddenly the piston was removed from the cylinder. Finally I could extract the rusty piston! I observed the extracted piston. It looked there was no risk of the leakage of the fluid because the hole I made in the piston was not penetrated. Thinking the function that this part only holding the rod connected with the clutch pedal , it could be reused if the hole would be filled by the hard material. However , be...

Clutch master cylinder overhaul #2: tough match

I disassembled the removed clutch master cylinder. And I found that the piston was heavily rusted. I tried to hit it with a hummer , Pushed the piston using the vise clamp like this. However , the piston was heavily sticking by rust and it could not to be moved today. The brake master cylinder was replaced in the past , however , the clutch master cylinder was not. Therefore , the condition of the clutch master cylinder might be worse. Tentatively , I would spray the rust-penetration lubricant from both sides of the piston and try again in a few days. If it doesn ’ t work , I would give up the overhaul and order the new part. ( My original blog was written on 2nd July 2009 )
