wastegate nut

[fred633]

What is the part number to the nut that holds the wastegate on? Can not find it on the diagram. It is a M8 stud coming off the manifold for the elbo. Fastenal nor mcmaster have one with a 10mm head so have to order from bmw but can not find the number.

Should be the same nut as #13 in the top diagram which fits the identical #10 stud on the side of the housing.

P/N 11651271988

The housing is held on with 11621273590 (#9 second drawing) and #10 in the first is for the exhaust. Wanting to be 100% sure before I start ordering $10 each nuts.

Good luck to you. You should probably search google images for 745i turbos.

Regular m8 nuts work just fine.

Regular m8 nuts work just fine.

no they do not. The clearance is to small for a regular m8. Standard m8 is 13mm wide and the stock ones are 10mm wide. Mcmaster carr and fastenal both do not have a 10mm wide in any m8x1.25 pitch nuts.

I have a bunch of M106 hardware. Looking at some nuts right now. On closer examination they are all M10 for the manifold studs.
