Question about rebuilding/refreshing your own 915 trans

[85RedCarrera]

What can you accomplish on the 915 trans without possessing Porsche specialty tools?

I haven’t opened the case yet, but I’d like to know whether I will be able to at least disassemble, clean and inspect/check most dimensions.

Any input appreciated.

You can do everything, just harder.

That’s encouraging- thank you!

Thanks Matt- that is an incredible resource… lots of detail and step by step!

Although, I would buy the special tools (especially the syncro tools) and then resell them to get some of your money back. You can use your house and an old clutch plate as a holding tool, that's free. With the tools, it's so much easier, safer, faster and more pleasant.

Yes, I definitely am not interested in breaking anything. Alignment of things during re-assembly seems to be one of the major problems with not having ANY specialty tools. No doubt, I will have to buy some of them. Hoping to make a couple, as well...

I'm interested in making the holding tool made from a clutch you are talking about... do you have any pics of it?

Many here have DIY'd a 915 rebuild. I bought some tools and made others. Thread here:
