Gearbox mounting bolt sizes

[David_17]

Anyone know how many and what size/thread bolts are used for a type 9 gearbox to zetec??

Need to get myself a handful :)

Just popped in to catch up on some of the recent posts & noticed this :)

I have just had a look on my engine ( I used the original Zetec bolts )

They are M10 X 40mm set bolts ( Fully threaded bolts ) standard metric thread.

One difference over a standard M10 set bolt is that the head size is reduced to take a 13mm spanner .... I believe there is still enough room for a 17mm standard hex head though ;)

If memory serves me right, 6 bolts will do the trick.

Hope that helps Dave :)

beware some earlier posibly kent engined 4 speed bellhousings had UNC a thread that looks like M10 but will break bell housing so clean the thread out cafully dont force the bolts and you will be fine all later bellhousings are fine and deffinatly M10 hope this helps.

There was a slight clue in the word ZETEC :rolleyes:

Metric only on the Zetec engine ;)
