Rear axle cleaning

Continuing the cleaning of the severely oil soiled rear axle.

At first, according to the advice from my friend, I attached the tape on the opening of the brake pipes to prevent the intrusion of small insects.

After that I cleaned and cleaned and cleaned … the severely oil soiled rear axles.

My plan for this day was to start the painting, but I couldn’t reach to it.

And far from the replacement of the oil seal and bearing that were main topics of this repair.

Repair of the car that had been left for a long time took long time always because unexpected problems were found as usual. ☺︎

It seemed that the rear hub bearing had backlash. I decided to replace them to be free from worry of troubles.

I also ordered new wheel nuts together although still it would take long lead time to use these wheel nuts for the shakedown of my “onboro ALFA”.

I was considering how I could remove the hub bearing from the axle shaft.

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....

Brake master cylinder overhaul #1

I started the overhaul of the brake master cylinder after the clutch slave cylinder. This day ’ s work was removal and disassembly of the brake master cylinder. My “ onboro ALFA ” is early type ( Mk. I ) 1750GTV RHD. The brake master cylinder is made by BONARDI and it is installed on the frame under the floor together with the clutch master cylinder ( this is made by BENDITALIA ) . Regarding the removal , there was a little try and error. ( 1 ) Remove the pipes Then , I tried to separate the linkage rod connecting to the brake pedal. However , the fixing nut was so hard that I changed the process. ( 2 ) Remove the bolts fixing the brake master cylinder on the frame. ( These bolts were also fixing the clutch master cylinder penetrating the frame. ) ( 3 ) & ( 4 ) Separate the linkage rod from the brake pedal , and remove the brake master cylinder together with the linkage rod. ( The linkage rod and the pedal were fixed by a split pin. ) ...

Fuel pump (The original blog was written on 15th Aug. 2007)

Although the gas was refilled , the gas didn ’ t come to the carburetors. The electric fuel pump was working , but it still did blank beating. I replaced the pump soon after I bought this car…but it was about 20 years ago! So , I decided to replace the electric fuel pump to new one , and to change the location of the pump from the engine room to the trunk room ( because for the electric fuel pump to push the fuel is better than to pull the fuel ) . I bought the Mitsuba electric fuel pump , fuel hoses and a fuel filter by auction and installed them in the trunk room. ( The wiring is tentative. But I am ashamed because the trunk room is so dirty… ) However , even the new fuel pump was working well , the fuel didn ’ t come. I guessed that the inlet of the fuel sender unit in the tank was sticking. I remove the unit from the tank and found the rusty unit and its inlet was perfectly blocked by the rust ( I forgot to take the pictu...
