Replacement of the rear axle hub bolt

On this day I was busy with home tasks so it was difficult to find the time for the repair, but I could manage to find a little time in the late evening.

Regarding the hub bolts of the left rear axle currently repairing, the thread (left handed thread) of one of the hub bolts was damaged in the past.

I thought I should order it to replace, but I found it while I was checking my stock parts a few days before. Thinking about it, it might have been ordered when I had ordered many parts a few years ago. Recently I often forget the parts or tools I purchased in the past…that is bad!

I had little time on this day, so I just prepared for the replacement. Since the tip of the new bolt was very edgy as it was cut, I refined it with a file.

The other work I did on this day was the replacement of the O rings at the accelerator pump jet plug of the WEBER carburetor.

I found that the O rings at the accelerator pump jet plug were melted by gasoline. Probably the quality the O rings included in the WEBER overhaul kit I used before was not good. Therefore, I replaced the O rings with new ones which had better anti-gasoline durability.

But the size of the new O rings seemed to be little bit too big…

I would replace them with smaller ones in next time.

It was fun for me to do this kind of things while listening to FM radio at night. ☺︎

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!!!
