As above my speedo drive has gone on me clocks checked the cable and it ok disconnected it at the gearbox end and spun it up using electric drill and its fine..............

So its the drive in the box been told this now means that the diff bearings could be going or gone however there has been no noise????

Is it possible that the drive gear i believe being plastic? has bit the big one or is the drive gear on the diff also plastic and that could have gone too.................................oooooooo also its not a lsd but a xr box as i couldnt get a good box for mine when putting it back together??



cheers

you can change the part what the cable goes into on the gearbox, they normally fail aswell

 

One out of 2:

1) If you are lucky, its only the smal gear that the wire connects to thats broken, its a easy fix, up with the old, down with a new

2) The plastic gear inside your gearbox has failed (mine did).
Replacing means dropping the gearbox, and taking it apart! (or get a replacement gearbox)
Yue can see the brown plastic gear here, next to the dif bearing:

Have a look at some pics from my rebuild here:

Lets hope its just the replacement gear thats failed!
Good luck

Edit: They are both plastic

 

anybody tried changing one of the small plastic speedo drive gear in the car i did snapped the pin and now i cant get it out anybody had the same problem dont wanna have 2 drop the box help me

sorry for hijackin ment to ask about this for ages

 

so if i take the pin out of the side how do i get the drive out of the gear box do i require a special tool ??? or need to know the special method of removing it??? (slide hammer etc???)

cheers ppl

 

If you manage to get the pin out (its a bugger to get at!) you connect the speedo wire and pull it up using the wire its just hold in place by the little pin. If the small gear you take out looks ok, and the speedo gets a reading when you spin it _fast_, then its gearbox time I am afraid

Good luck, hope my english makes sense!

 

ive snapped the pin looks like box out if nobody has any ideas how to get it out?

 

It is snapped close to the housing? if its a few mm left, try using a wire-cutter or something. Also, you could try sliding it out from above, using a screwdriver & hammer, as you shuld be able to se the pin from above.
Probably not too much space around tho.
If your speedo don't work I guess thet the gear behind the diff has given up, so the box need to go out anyway

 

gavintwopies,
What you need is a really sharp pair of side cutters and put them on the pin and lever them against the casin it will slowly come out bit by bit! i've done thousands! if they snap you have to drill m out and to do his its a box out job!
the cause for this goin is usually the diff side bearings, you wont usually get any noises, the speedo ill fuctuate then stop workin, by this point it chews the plastic speedo drive! really common mate!! new beaing i think

 

i've herd this off a few ppl now........

But i had this great idea if i keep my fingers in my ears for long enough it might just magically jump out the gear box and fix its self ..........sorted!!!!

 

ill have a go at the weekend dont think there is anythin left to get hold of though

 

gavintwopies,
I like ya style dude! i ve been meanin to put that into practice!!!!!!!!lol

 

rite then had a look tonight and its odd , very odd

the drive gear that is on the diff has come loose and with the worm removed i can freely turn it round the diff its mounted on with my finger end through the hole.................. so its box off then
luckly its only a xr box and not a lsd turbo one
so i have a spare and i'll hoy that on before this weekend as its ment to be going to york raceway for the 1/4 mile rwyb day on sunday

 

gavintwopies,
You better get another box just in case for sunday night! lol

 

rite well box now swapped and speedo fixed just discoverd now thart the syncromesh on 2nd on the old box was knackerd too so double score............
