Defender bonnet tyre mount

**pop058** · 18th October 2021, 11:46 AM

Anyone know what thread and pitch the hold bolts on the bonnet for the spare wheel are ?. Contemplating putting my spare back there and need to run a clearing tap down them The threads are a little weather beaten to say the least.

TIA

As far as I am aware, bonnet mount for Defenders has never been sold (or at least) approved in Australia. This being the case the mount you has most likely been designed for or copied from a Series mount, and as such is most likely 9/16" BSF.

My 92 has the ( pictured) mounts from factory. Inc's 130 also has them. I tried a 12mm as well as a 1/2" UNF and they both ( just) start but I would prefer to run the correct tap down them first.
I tried the one from my 2A and it is way to big.

Thought you would have had a thread gauge Paul.

My 84 110 has a similar mount but the lock pin goes through a wheel nut hole not through the centre.

By memory I replaced the bolts a few years back from my metric collection if that helps. Cannot find my thread gauge due to a shed rearrangement that is incomplete.
