Gents, I have sold my race car and am thinning my treasures! This came 14 or so years ago from Roger Sheraton when I purchased 2 race boxes with 901 shafts, etc I have a 914 LSD, which Matt Monson says fits the 914, 1969 mag 901, 70-71 mag and 72-74 915 with 7:31 CWP. It worked like a charm for my vintage Type 4 E Prod. I have not disassembled the unit for inspection. As you can see with pics, I have the flanges and bolts. Not interested in separating at this point. Shipping from DFW area. Prefer local but am willing to work with purchaser. $2500 plus shipping, etc. Thanks old914dog

I would post on the 911 parts for sale on Pelican. You might have better luck there.
You can buy a new aftermarket LSD for $1500.00.

Food for thought.

I've been watching this post with great interest as I'd like to eventually obtain a LSD.

However, a complete Trans with a Quaife recently sold for not much more than what you are asking.


http://www.914world.com/bbs2/index.php?showtopic=337062

Quaife has advantage over factory LSD in that it is a helical gear LSD that doesn't require maintenance and/or new plates like factory LSD with friction plates eventually will (especially if raced previously).

I do understand that it is factory LSD which holds some appeal for purists. However, not knowing the condition of the internals is a show stopper for me. Replacement of the friction plates, the metal drive plates, and the springs can quickly add up.

I'll keep watching. I missed out on the the other one, and maybe I'm wrong about the value of this one. I'm still learning the true value of some of these rare 914 parts after having been away for so long. (IMG:style_emoticons/default/beerchug.gif)

Problem with a Quafe is that they induce corner entry understeer and they also are not adjustable in any way.

All limited slip's will add under steer - nature of the beast. Helical's are indeed adjustable - bias ratio can be varied as a function of design typically about 2:1 but can be varied. Less bias = less under steer = less ability to transfer drive torque. No free lunch!

Likewise most friction disc LSD's are not adjustable other than by design (# of plates and by spring pre-load at the time of build-up).

Most importantly to all conventional LSD's - get a wheel in the air. No torque transferred. In practice - not an issue for most 914's operating on the street (IMG:style_emoticons/default/biggrin.gif)

Unless you're talking electronic LSD's or torque vectoring differentials but that's another animal altogether.

Everything wears. It's just a matter of degree. However, friction plate LSD's wear much faster.

Still pretty neat that these are floating around and glad to see the parts offered up for sale.

I've been trying to track down the part number that seems to be inscribed on these - not matching PET. Don't seem to follow Porsche numbering.

Anyone know what they are?

Going from an open dif to lsd or quaife is an eye-opener the first time you hit the gas in a corner!! A locked or welded dif is another world! First time for me was Road Atlanta with a welded dif in the rain....you have to sling the car, just like a dirt tracker!! After running all 4 difs, I think my best times were with the lsd. Anecdotal, yes...but true for me. Best aide to going fast is more seat time!!! Spend less on "stuff" and practice more and read about chassis setup. Track tire temps, all of it. Just saying!

The inscribed numbers appear on both the ring gear and the pinion gear
They are manufactured and machined as a pair and are marked to keep
them from being paired with the wrong partner.
They are not part numbers.

Hmm. Could be, but in the case of this LSD, it wouldn't be matched to a ring and pinion would it?

Maybe numbers to match the two parts (case and cover) of the LSD?

Any factory part numbers on the LSD itself? Per PET should be 901 332 053 13

I see your point and I agree.
It's unlikely the LSD is marked to match the gears.
The inscribed numbers in your photos are most likely ZF production
marks. Not part numbers.
As you point out, probably to match the two major components of the diff.
Much like a pair of transmission gears.
My bad.
