secondary chain oiler

[dusty1]

I removed rear chain oiler fitting from case which has a 45 degree downward angle and a nipple coming off it which goes to chain oiler nipple on pump. I would like to replace it with a straight fitting as a crankcase breather,threads are 1/2x20 i think. Cant seem to find a fitting like that anywhere

     I think that those are 1/2" NPT fittings. Here's a link to one. I've got one, don't remember where it came from, I'll try to find out for certain what the thread size/pitch is later today.    Bill

Pretty sure the case breather threads are 1/4" Pipe US

     I think you're right. I was thinking OD though it's the ID of the fitting that gives the measurement.

Thanks! I thought it was the OD also
