T350 Sump Plug

[ca700470]

Hi,

Does anyone know the size of the allen key required for the sump plug at the back of the engine, between the block and the gearbox?

Looks about 13mm to me but I need to make a short tool to fit. So i
ideally need to know before I start grinding up a perfectly good Allen key.

Thanks

I used a 13mm bolt and a 13 nut.. did them up tight.. and sawed the remaining thread off.

No need for an allen key.. insert the bolt.. and use a ring spanner on the nut..
