Also looked at the subs, but they are a casting without any numbers on them.. At www.mittelmotor.de you can however chase down most all numbers for original porsche parts in their catalog and order them at the same time if you feel like it ;-) Rich: not sure what there is to rebuild as only the original brass disks can and do wear, even if they seem original thickness. Learnt this from Paul. See pics on former pages, its quite simple once you see the inside. Last edited by Wally; September 13th 2011 at 15:29. |

Just removed the ring gear and bearings so both could be compared in detail.
All the important measurements that would impact ring-gear distance are extremely close (beyond my accuracy anyways), for all practicle purposes I would say they are the same. Lets hope I am correct... The only thing I really need, is a set of new ring-gear bolts ($$ no doubt) as the flange of the LSD is 2mm thicker (to the direction that doesn't impact ring gear distance of course ). |

No issues though ... used G64 front diffs are going for ~$200 on EBay, going to try another local source first. Good luck with the swap ! Sandeep |

I am still looking for the correct new (longer) bolts I need for the swap over of the ring gear. Its a M12 x1.25 bolt in 12.9 grade, but would be nice to have the part number. Mittelmotor don't list inner diff parts. I'll look at auto-atlanta in return |

If I'm looking for Porsche part numbers I just go to the Porsche online PET rather than via a 3rd party.
http://www.porsche.com/uk/accessorie...artscatalogue/ I had an issue accessing the 996GT3 catalogue but the 996 catalogue list two possible options for the ring gear bolts (with LSD). 999 217 152 01 or 996 332 276 00 depending on which diff (can't quite read the full number in your photos). The GT2 catalogue lists the 999 217 152 01 bolt for use with the 996 332 083 9B (40/65% GKN) diff. The bolts are M12 x 1.5 x 22,5 Hope that helps. Last edited by Bruce.; September 14th 2011 at 06:01. Reason: Edit part number as per Wally below. |

oh..... and the front diff axle flanges from a 964 C4 are "964 332 209 01", if you need that number.
Interestingly, the gears inside that front diff (which I guess the subs splines attach to) have a 950 part number and are straight from a G50 box (plus 928 & 968) Last edited by Bruce.; September 14th 2011 at 05:34. |

You wrote 999 332 276 00 but I am sure you meant 996 as first 3 digits for this one. I could open de 996GT3 as well as the 996GT2 and both list the same pic and part numbers for that 9B diff.. I do indeed have that GKN diff however, so I am a little confused now which one I need... Could you check if your assesment is still correct, pls?

The 996GT3 catalogue is perhaps clearer (i got it to open at last).
http://www.porsche.com/all/media/pdf...T3_KATALOG.pdf Like the GT2, it lists the LSD (the only diff) as part number 996-332-083-9B. It is hard to read from your photo the last two digits but could this be your diff (or does it end "00" or "01"). The GT3 & GT2 use the 999-217-152-01 bolts (only option listed). (also corrected the part number above for the other bolts, as you mentioned) Last edited by Bruce.; September 14th 2011 at 06:02. |

Thanks Bruce, the diff number ends with 9B, so its spot on.
I'll order the 999.217.152 bolts then It will be fun to later couple a 1200 T1 engine to a 996GT2 equipped diff with a Gears Transmission friction plates upgrade |

Bruce,
By any chance, do you also know the correct torque setting for these bolts? I did came across it once, but didn't save the info then...:-( |

Steve:
From what I can gather, that is the "street" LSD. Wally's LSDiff is the motorsport version which is tighter than an inappropriate simile. Wally: For the torque settings, I think the safest plan would be to send another email to Guard. I'm sure he will spare 2 mins for a customer. Internet chatter suggests 50ftlbs+90degrees with locktite for a standard diff but I wouldn't trust that spec without confirmation from a reliable source such as Guard.

Hope to be able to pick up the bolts tomorrow afternoon as they were in stock at the central porsche dealership over here. |

Wally, sorry for changing the topic, but could you detail the modification you did to the oil filter pressure relief ball/spring setup? I was surfing the keversite.nl forums with google translate, but it's not that good :P
Thanks!

Easy: drill 5.0mm hole in top above ball-spring, tap with M6 tap and install M6 bolt with lock nut. Install with loctite
These are/were the original bolts: 22.0 mm shank length. I need 2mm more (i.e. 24.0-24.5mm). I do hope the ordered bolts are the correct length, but how could they not be? |
