The day my "onboro ALFA" would revive

Last time when I did the maintenance of WEBER , I found fuel leakage from the fuel hose connected to WEBER. I recognized that the gaskets of the fuel union had to be replaced. I bought a gasket sheet with 0.8mm thickness at a motorcycle part store.  I guess it is cheaper if I order it at automobile part wholesaler.  But I bought it at motorcycle part store because I wanted to get it quickly.  I found there are lots of parts , which can be utilized for a historic car repair , in a motorcycle part store. ☺︎ I copied the gasket shape on the gasket sheet and cut out them with a cutter , but to cut out the rounded shape was little difficult.   It took more time than I expected.  I should buy a circle cutter in next time. The appearance was not very good , but it should be no problem functionally.  And it would be invisible after the installation. After the installation I activated the electrical fuel pump and confirme...

Recently my onboroALFA had a difficulty in engine start. The phenomenon started before the restoration of the fuel tank I did almost 1 year ago.  Regarding the engine start of Giulia , normally push the gas pedal several times to operate the acceleration pump , then the engine should be started.  It didn ’ t work.  But the engine could be started with choke.  After the engine start , there was no problem.  So , I guessed the acceleration pump had some problem and cleaned it.  But the problem was not solved.  That was the situation. I overhauled the WEBER carburetors , but 2 years had passed already since then.  I thought probably the gasoline deteriorated , or some foreign matters may be clogged in the fuel line. However , when I was looking at the WEBER manual , I found some points , which could cause the bad engine start. There might be problem in these parts shown in the following picture and it could be cleaned wi...

I got the new weapon to clean the inside of the clutch slave cylinder.  The honing tool for the master cylinder ( attached to the drill ) I bought at the tool store.  Cost was about 1 , 000 JPY.  It looked like a ray gun ☺︎ Fix the slave cylinder in a vise. Drop the engine oil to the inside of the slave cylinder , insert the honing blades in the slave cylinder and power on the drill.  Then , the honing blades were spread by the centrifugal force and polish the inside of the slave cylinder equally.   The inside of the slave cylinder became like this. The other parts were also cleaned. ( My original blog was written on 20th Apr. 2009 )

On one day before I started the repair of my onboroALFA , when I pushed the clutch pedal , I felt the feeling like something was bursting at my feet and the clutch pedal lost the reaction force suddenly.  Then , I recognized the slave cylinder of the hydraulic clutch became useless. At that time the brake calipers were also perfectly sticking.  So , it meant all of the hydraulic system of my onboroALFA was dead. The overhaul of the brake calipers was finished , however , I had to repair the brake master cylinder , clutch master cylinder and the clutch slave cylinder yet.  At this time I started the repair of the clutch slave cylinder.  I would remove the clutch slave cylinder and checked whether I could overhaul it or I should replace it with a new part. This was the status at this moment.  The cylinder piston popped out and the boots came off.  It was rusty and looked very bad condition.  At the front and rear side of the clu...

I continued to work on the assembly of the rear axle shaft on the left side. I started from the installation of the new hub bearing.  Method was in the same way as I did for the right side. Insert the new hub bearing to the axle shaft , put the old bearing on it , put the long pipe on the old bearing and insert the new bearing by hitting the pipe.  The diameter of this pipe was just fitted to the hub bearing. After installing the hub bearing , fix the hub bearing with the retainer nut. Next was the replacement of the oil seal for the axle shaft. The oil seal on the right side could be easily removed with a minus screwdriver , however the left side one was sticking. Therefore , I looked for something in my garage that was good to remove the oil seal and I found the metal bracket that was used for constructing my garage.  The oil seal could be removed using the metal bracket and a hammer. In order to install the new oil ...

I started the assembly of the rear axle on the left side. First of all , I cleaned the rear axle housing which was heavily dirty with oil mud , and painted it with chassis black. Next was the assembly of the parking brake drum. I assembled the linkage of the parking brake checking the illustration. And went to the assembly of the brake drum springs. Also this time I used the vise grip to grab the spring and pulled it with my full power. Finally the revived rubber boot cover was attached.  It was little bit hard because the cover became thicker by pasting the tapes and adhesive.  But it became more robust maybe! Next would be the installation of the new hub bearing and the replacement of the oil seal. (My original blog was written on 3rd Mar. 2009 )
