Next task is to overhaul the rusty clutch master cylinder

The overhaul of the brake master cylinder was finished and I’ve started the overhaul of the clutch master cylinder located at next to the renewed brake master cylinder.

I started from the removal of the pipe lines.

In one of the pipe lines, however, the flare nut and pipe were stuck together. The pipe would be twisted in case the flare nut was turned. I tried several methods, such as blowing the lubricant or knocking the nut, to avoid collapsing the pipe. However, it seemed there is no way. So, I gave up rescuing this pipe line.

I separated the other end of the pipe (clutch slave cylinder side) and removed the clutch master cylinder with the pipe line.

I had to create the new pipe line by copper pipe.

I’ve started to look for the pipe flaring tool on the internet auction.

I did one another small improvement.

The O rings at the acceleration pump jet plugs of WEBER carbs were deteriorated by gasoline so that I replaced them with the gasoline-resistant O rings made by fluorine rubber. However, the size of them were little too big.

When I ordered the tool chest on the internet store, I also ordered the smaller O rings.

The new smaller O rings were nicely fitted to the plugs!

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....

Pad spring repair

One of the springs to hold the brake pads was broken. At first I thought to buy it, however, I tried to fix it using rivets. It seemed to be strong enough just to hold pads. Later I removed the rust and cleaned them. Note: I have been using this repaired pad soring for 10 years and there is no issue. Pad spring is not an expensive part ptobably (I don't know the exact price), but it is easy to repair if you have ar1750gtv hand rivetter. (My original blog was written on 10th May 2008 )

Body repair around the fuel tank

I found some rust at the flange in body around the fuel tank as I expected. I believed this level of rust in this area was quite usual for old Alfa Romeo. It seemed that this area didn ’ t influence on the body strength , however , I was considering the method what I could do by myself. Anyway in order to prepare the sheet metal for the repair at first , I started to look for the store where I could buy some sheet metal near my house. I tried to research the store on internet , but I couldn ’ t find appropriate stores. Finally I asked the person at repair shop , who did maintenance of my Renault 5 , about the store I could buy some sheet metal. They kindly taught me the store , but at the same time they gave me some sheet metal for free. That was enough volume for what I wanted to do. I didn ’ t expect it. Thanks a lot!!!
