5 bolts that mount engine/trans to frame

Pdr206 · Oct 15, 2020

I'd have to look again at my 69 norton, but I believe it is 5 different length/diameter bolts. I for the life of me, can not find them on Andover's site and I've been away from my parts manual for two weeks. Would like to order new ones as the bolts that came with my basket case were pretty chewed up.

Can anyone help me find the part numbers for these bolts? Again, they are what bolts the drivetrain to the frame, nothing else AFAIK.

Thank you!

Are these what you are after? They are studs, not bolts, but bolts can be used. This is from a 1971, but your 1969 should use the same parts.

Front:

Rear:

Hope this helps.

Check to see if the cradle stud holes are not oval or worn , particularly the rear 3.

I bought a very nice engine mounting kit from CNW. High strength stainless steel, 12 point bolt/nuts.

Studs work better than bolts since you can remove them without removing the inner primary cover if one breaks. Ask me how I know.

The pedantic response could have been there is one bolt and one stud that mount engine and trans unit to the frame, through the Isos. There are 5 studs that mount the crankcase to the front Iso bracket (2) and the cradle (3), and 2 that mount the gearbox to the cradle, but since you now know what you are looking for...good luck!

LAB must have been busy elsewhere.
