 |
|
Hey Guys,
I'm removing the transaxle G31 (1980 Turbo), just wondering if anyone know which size the XZN type bolt is that holds the shafts in place..
As a guess i would say a 4 or 5 but looking at the socket kits with this end at a few places they only seem to be starting at 5. Wouldn't want to buy it and then find out it's a 4 haha
Cheers |

Are you talking about the triple square bolts on the CV joints?

Yep sorry for not making that clear.
I'm actually going to need at least one as well (well see if i strip any lol) if somebody has any i could grab.
someone must have lost one.. and put another type of bolt in. it was just loosely sitting there :S |

I have a whole complete set of brand new OEM-spec bolts I do not need. They came with the new pair of half shafts that I just installed on the Club Sport, and I don't need them because I put Stage8 locking bolts in. You should consider replacing the whole set because they are stretch bolts and are not meant to be re-used. If you want this set, you can have it for $20 + $15 USPS priority mail shipping. Let me know. Oh, and I believe these bolts are hex-head, not triple square, so much better for installation, removal and wear on the head.
The triple square that I use on my bolts is 8mm. Not sure how that equates to the sizes you mentioned...

They are not 6 point T40 or T45, whatever. Completely different series.
As Ideola says, they are triple square if you`re a Yank or 12 point in the modern (metric) ROW. M8 12point.
Have a heap of old ones you can have for postage cost. However I suggest a trip to your local fastener store. Buy 24 or 25 of M8 x 50 cap screws, 12.9 grade in black. SAME grade as OE. and theoretically superior to any ZP bolts, like I understand the Spec8 ones are. Not rocket science, merely basic bolt science. Around 50c ea.

What the heck are ZP bolts?
Like Ideola, I replaced mine with the same Stage 8 ones he has mentioned. I have 23 OE bolts left (one was missing its head). Just cover postage, but I'd imagine that would be a bit more pricey than what RC is offering.

Yep they are tripple square also known as XZN. Although i might get further searching for 12 point/tripple square.... which i did. It might just be best to buy some new then if they are the stretch bolts as Ideola suggested.
Thanks for that Guys |

You understand incorrectly. The stage 8 ones I just installed are 12.9 in black oxide finish.

ZP == Zinc Plated?
No, Spec8 ones are not zinc plated.

Thanks for clarifying that misconception.
