wd 350 front oil pump plate
Hi, could any one tell me what thread is on the front oil pump plate that fits the nut for the pipe to take oil to rocker box, I have tried all sorts of gauges and nothing seems to match cheers Richard

Re: wd 350 front oil pump plate
Thread not stated in the parts list. Nut introduced in 1937 pt. no. 37-12-E365. New Part number 017180. It was used from 1937 onwards. Same on my 55 single. Not sure when the pipe from crank case was in use until. Anyway use the new part no. and remember, its a part used on singles for many years from 1937 onwards not just WD. Opens up your search for the part. Or are you just curious as to what thread type? Which I am sure would be a gas thread. Like petrol pipes etc.

Hi thanks for the help, I broke the thread on a original one, as the metal was poor quality aluminium. I obtained another which was made of steel. I thought that I might be able to make one in the future if I could know the thread. The nearest I got was a 7/16 SAE American thread

Ah plate not union nut, you can get a new plate from club spares.

You will see its pt. no. 000773, the old pt. no. was STD 773 as seen in your WD parts lists. The plate was used from 1930's onwards
I am sure it is a gas thread.
