diff rivets in 020 8v gti

[spankier]

Ive read in a few threads that the diff rivets are a weak spot in th 020 and 02a boxes.... whereabouts are they, obviously on the diff, duh, but do they hold the ring gear on the outside of the diff, or the planet gears to the outputs or what- got a proper gti box to replace the nasty diesel box im running at the moment (old gti one spat its dummy out after santa pod, oops!) and i thought i might aswell have a go at servicing it and bolt or dowel wherever the weak point is if possible.

they hold the ring gear on the outside of the diff

They secure the crownwheel.

There are bolt-kits available to replace them.

ta- should be easy enough to make bulletproof

They are a known weakness and will write the gearbox off if they let go, well worth replacing them with a bolt kit if poss.

they aint a weakness in 8v's, just 16v's. 8v's dont rev hard enough to wear them out

[Gambit]

seriously? ive never heard of an 8v box go ever - hence why majority of valvers now run 8v boxes - never stressed as much as a 16v box - they all go eventually though!

in syncros the 8v  can happily munch the rivets,   tho there under more stain in low gears due to grip 

[Gambit]

eh? 8v syncro? your talking 4x4's??

gearbox is stll scairly the same for most of it.

yea diff rivets are a big problem.. I have lost two boxes to this.  My daily at the moment must have 2 left MAXIMUM!!  Clunky clunk everywhere I go, lucky it hasnt got much power left or it would have gone ages ago!
