Painting of the air cleaner box, My old parts … etc. (The original blog was written on 20th Oct. 2007)

I cleaned the air cleaner box because it had to be removed for the WEBER overhaul. Now I was thinking to paint it.

I was considering the color of the air cleaner box. However, as a primer paint, I tentatively painted it by brush with the gray rust prevent paint I bought before.

After painting I installed the air cleaner box on the engine as a trial. But immediately I found it was bad color combination. Which color would be interesting except for normal black?

I had several old parts I was thinking to install on my onboro ALFA.

One was the Abarth steering wheel that I used for the 1st generation Honda Civic I drove when I was a student.

It looked not so bad on the picture, but actually the leather condition was very bad with lots of cracks. I liked it very much, so I could not throw it away. I was thinking I wanted to use it at the first time in 20 years.

The other one was this wheel.

I found it on the auction 2 years ago. The seller said he used this wheel for Alfa Romeo and it had PCD 108 and offset 19mm. I had never seen this type of wheel for Alfa Romeo, but I liked and got it.

(Well, here is a quiz, but does anybody know the name of this wheel? ☺︎)

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 )
