Setting a Porsche 915 Transmission Differential

[@adanreinosa7599]

Thank You...I am rebuilding my 915 81 911SC with 455k miles original following your great tutorials..Best

[@klassikats]

Glad to help Kurt

Apparently, your training included the “leave no stone unturned” schooling. Can’t believe that i made it through both vids. I’ve been thinking about the 915 transmission for importing into my 914-6. If it ever happens, I’m sure to go looking for an expert.

Don't forget that in a 914/6 you will need to flip the ring and pinion otherwise you will have 5 reverse gears and 1 forward gear Kurt

Very much appreciate the time and effort you put into an excellent production. Cheers from Adelaide.

Thank you and thanks for watching

Super great of you for doing this! If I might suggest, it would be really helpful if you could spend a moment showing the tools your using with model or part numbers and manufacturers brand name.

[@klassikats]

Great suggestion! Although I will say almost if not all of the tools I am using are no longer available. Sometimes you can find them on the resale market but be prepared to pay a lot. The last time I bought a set of the differential setup tools for a customer it was around $15,000 and took a bit of searching to find everything. Kurt

Straight from the WSM this is probably as close as one can get to going back in time and taking part in factory dealership training. The instructor my dad had demonstrated a unique quick check method for ring and pinion setup that involved rolling papers… For those of us w/o means to check pinion depth would you say gear marking compound would be a good indication of an incorrect depth ?

[@klassikats]

Daniel, As a matter of fact yes I was taught this technique in 1990 while attending the factory Porsche training school for transaxles as part of my apprenticeship training. When it comes to using marking compounds to set up a diff, it will work for giving you a rough idea of how the gears are meshing. However, it lacks the degree of accuracy that you need to guarantee a quiet running gear set. Now what I would suggest if need to set up the diff, would be to have a shop that has one of these tools do the setup for you. Then you can finish rebuilding the rest of the transaxle yourself. Thanks for watching Kurt

Thats a nice tool you use for checking the backlash and preload... did you make it?

[@klassikats]

Michael, No i did not make that one it is a factory Porsche tool. Thanks for watching Kurt

[@billswim]

Where can one buy one of those tools?

[@klassikats]

The VW 383 tool is not available new any more, I do see them from time to time being advertised on forums and other auction sites. Be prepared to pay a lot of money though the average price for a complete set up with every thing you need to set up differentials will set you back around $10,000

One of t h e best videos on the 915 I’ve seen to date. Such an amazingly, thorough production. Ive seen some of these tools from time to time, not easy to obtain let alone everything you need to do the job well and right.

[@klassikats]

@@thinkerdoit Thanks for the kind comments. Yes, these days it is tough to find a lot of the tools required to do the job. Most of the tools you see in our videos I have had for over 25 years. Thanks again for watching...
