Tipi's '69 LWB

No wonder gear change was 'a bit' loose. Shift rod bushing was completely missing! So I guess easiest way is to loosen that wire secured bolt and take the cup off? I have the gear box out of the car.

that's a classic area that and the link to the gear box at the back of the tunnel you will be amazed there is lots of web sites saying about it but I helped one 912 owner out in the US with my pictures he has sent me a thank you card because he was about to send the car away for a full GEARBOX rebuild!!!

all done for under 100 bucks and 4 hours

Yep, for me it took about ½ an hour to tear it apart and the same to put back together. And I only used that one 10€ bushing. So the cup and rear bushings were left over, as they are 'very tight' (pronounse like the Goldmember) I left them as is.

This week I decided to disassemble the brakes. I'll rebuild the calipers and machine the rotors. Rear protective shields must be renewed, but they are not very expensive at porsche dealer, about £20 each. I see that it should be the same parts from '69 all the way to '89. Other parts are rebuildable. For more pics, click here.

Damn it was slow, it took almost two hours to clean one rear caliper for painting! Mostly I used angle grinder and wire wheel, and then light sand blasting to the spots the wire wheel was not able to reach. Next question will be what colour I should paint them? I believe they were originally plated with yellowish zinc coat?

Cad plated look is the way to go in my eyes.
Any other colour, especially body colour looks plain wrong

silver is the norm or black

Best done with 2PK paint it lasts longer... I have a set here I need to do ASAP

Don't worry, no way I'm going to paint them red. I have some what originality in mind, but I don't think I'll try zinc or cadmium plate them at home. Black or silver are the top choices at the moment. There's some caliper paints also available, have anyone tried those?

save your self the money and go straight to the paint shop

I dipped 912 brake discs into mild citric acid for a couple of days and the result was impressive. This was the first time I tried the acid dip for rust removal and I think it works beautifully. Now I got the calipers boiling. More pic's here!

that's a good idea I have some that need a clean I could dip them before painting them..

Will have to dig some out at the weekend..

And what is best thing is that, this mild citric acid is almost grocery! I used 99% acid, which ca be bought for agricultural market for about £20 per 5kg can. It's used as piggy diarrhea medizine as is!

I had pretty good rust removal results by soaking parts in vinegar for a day or 2.

Just went to the local netto and bought a couple of litres - v cheap

Tipi_dwl · Post by **Tipi_dwl** » Wed Jan 14, 2009 11:21 am

I used 15l water and about 8dl acid making it about 5% solution. I read that too strong solution doesn't work that well, OK being 3-5%.
