Rebuilding a Porsche 915 Transmission Final Assembly. 

Thank you Kurt and wife! Nicely detailed, excellent vid!

Excellent and thanks Kurt! It would be beneficial to your viewers to see you cover the maintenance of the 5th/reverse detent system. It was somewhat glossed over in this video. I highly recommend that anyone who services one of these transmissions take the time to remove the two roll pins and remove the components for cleaning both the components and the bore. I once saw a gearbox that was freshly rebuilt by a local shop get stuck in 5th gear because there was 50 years of worn synchro debris and gunk built up to the point of preventing the detent system from moving freely. Under these circumstances the components will not freely fall out of the bore for servicing. You can insert/force a series 7mm steel balls into the bore from the 5th/reverse shift rod hole to slowly force the components out of the bore. Then take an 8mm ream or pipe brush to clean the bore. Thanks again!

I just finished the rebuild of my 915 (synchro, dogteeth, bearings, miscellaneous, preload, backlash, pinion clearance). Never worked on a gearbox before. These videos were a extraordinary complement to the 'Zimmermann' Wiki files. The occasional email got answered too! Thanks Kurt for helping me out!!!

Thank you SO MUCH for producing these videos! I’ve got a 911 trans that I damaged and partially disassembled and have been slacking on putting it back together.

Awesome series. Thanks so much for posting. I’m about to send my transaxle out for rebuild and this has helped me go into the process much more informed.

Awesome video, thanks for sharing.

Great set of videos. Thanks

Well done everything is according to the rules of the art :) Just Perfect, I download because really excellent work

Your videos are always appreciated!

Thanks Kurt. Excellent series of videos.

Lovely, as always.

Incredible workmanship . Best I've seen .

I just bought a 79' 911 SC and it will not go into first gear, all other gears are fine, no noise or grinding. It's like a hard stop trying to select first. Is this a common problem? The vehicle has 75k miles.

Argument with a friend over downshifting and whether double clutching, with a throttle blip in neutral to match revs, or a single shift with a throttle blip to match, is better for the 915 gearbox. Seems to me both methods match revs, shift fork and selector move and by matching revs, the synchros would experience less abuse. Friend maintains that only double clutching saves synchro and wear. What is your opinion? Great video series, thanks!

I would like to attempt this. I have rebuilt my 3.2 engine with no previous experience but this looks more complicated with tolerances. and special tools required.

This has been an excellent and very informative series, much appreciated! I do have one quick question; can you explain why it is important to assemble everything without oil? Thank you!
