TYPE 915 tech info ?

[ty901]

all;
i tried searching and, unless my search arguement is faulty (entirely possible ), i came up empty. i have plenty of tech info on 901, 902 & 911 transmissions, but nothing on the 915. can anyone point me in the right direction, please ? i'm interested in knowing the contents (R&P, gear stack, etc.) based on type as stamped on the case. eg; 915/55, 915/45 etc.
any help greatly appreciated.
TIA

It must be your fault.

There is a wealth of info here on Pelican.

Try typing using different words and not the numbers.

complete porsche P/N list with diagrams

See this post. Get P/N book from Porsche in .pdf for free online. Use search function with Acrobat

I find these invaluable for nailing p/n's. especailly if things are messy like mid year changes.

great reference and you don't need PET loaded on your machine. i'll mark that site. thanks!
what i'm after in this case is the contents of a given 915 by type. 915/55 , 915/45 , etc. the search engine doesn't like the '/' apparrently. i tried searching on 'gear chart' and came up w/ this

<Re-gear tansmission - 915?>

the first response listed the gear stack & R&P ratio based on 915/67
this is what i'm after. i've sent a PM to Bill inquiring further.
hopefully that will do the trick.
thanks all!

I'm looking for the same info. Recently a chart was published here for the 901. Shows tranny number and gear ratios. We are looking for the same thing except for the 915. Searching pics up bits and pieces but not all for comparison. Soooo we need a chart like this one but for a 915

3 25:27(PR)

HI ty901 do you have the gearbox No' as the spec books do not list a 915/55 the nearest is 915/65, if you have the box No' it will then give the year and narrow the type/box down for info.

Just a follow up and for future searching.... I found this info posted by 2.7 racer in another thread. Good stuff!

Jim Sims did a great write up on rebuilding the 915 a few years ago. It's extensive but a home run of info.

I've been looking for it for over a year and can't find it. I printed out about 20 pages and the borrower misplaced it when he moved his repair shop.

One of my most used threads is the "Ultimate Brake Upgrade" thread. We need a similar one for the 915 where the good threads are condensed and listed. It would be a daunting task though.....

close but no



it's like he wrote a book in 2 different posts about 2 weeks apart.

each one was a few pages of hard info. And Jim hit on all details you'll never find in book text.

thx for trying
