WEBER was installed! (The original blog was written on 30th Sep. 2007)

Despite the WEBER was already assembled, I was busy recently and could not find the time.

But today I could manage to find a time and installed the WEBER on the engine!

I also wanted to try the engine start. But I found that the cam cover was dirty and for some reason I began to remove the cam cover to clean it. As the result it became dark and I withheld to start the engine at night.

I became very hungry so we enjoyed a barbecue with “Shichirin” for our dinner.

(“Shichirin” is a small portable stove for cooking with charcoal made by clay.)

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 )

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...

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...
