Fuel tank repair: Day 5 --- tank sealer

Next process was the coating of the tank inside using the tank sealer.


At first I opened the can and mixed the sealer well.  The viscosity of the sealer was lower than I expected.


I poured the sealer into the tank carefully to prevent spilling it and closed the inlet of the tank with duct tapes.


After this, with imaging the movement of the sealer inside the tank, I held the tank, turned over, swung around, or jumped in order to spread the sealer completely inside the tank.
(There was no picture that I was dancing with the tank because my both hands were occupied.☺︎)

In 30 ~ 40 minutes my breath became rough and I stopped dancing.  I opened the inlet of the tank and returned the sealer to the can.


Surprisingly, the sealer used to coat the inside of the tank was only 1/5 of the full quantity.  I remembered that on the label they said the quantity was enough to repair 100L tank.  It seemed 4 more tanks could be repaired if remained sealer wouldn’t be hardened.  (But I didn’t have rusty tanks anymore.☺︎)

The inside of the tank was like this.



It looked that the inside of the tank was nicely coated by the sealer.
The instruction said “to dry the inside at least for 24 hours, preferably for 4 days after coating”.  So, I kept the tank with this condition to dry the inside until next week.


Before starting the repair of the tank I had lots of concerns, such as the removal of the tank from the body, the cleaning and the rust removal, making holes on tank by rust removal and so on.  However, in the reality, it went well although it took time.

It was much cheaper than the replacement with a new tank.  Moreover, it was good for me that I could use the original parts of my Alfa. 
I spent more than half of my summer holiday on this repair.  However, it was really good for me that I could complete the rust removal of the fuel tank, which was my homework for summer holiday. ☺︎☺︎☺︎☺︎☺︎

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.
