Need Tap for Oil Screen (Cont A-65)

[Peterroy]

The female threads that secure my oil screen to the engine are messed up and I need to tap them. My best guess is, the threads are 1 3/4-16 (does that sound right?). The cheapest tap I can find is selling on eBay for $96. Does anyone have one I can borrow?”

I don't have one. I have a 2"-16 and a 1.5"-16.

If I was in your spot I might try taking a smaller tap that had a 16 pitch and use it as a thread file to clean up the internal threads on the accessory case.

Ever used a "poor man's tap"? You take a bolt with the right thread, spin a nut down to the head, use a DREMEL to cut a length wise slot down the threads and unscrew the nut to clean up the thread. Steel bolts are good for a number of thread clean-ups before you wear takes them out, Especially good at cleaning up threads in aluminum. Cost? Under a Buck. Be VERY careful of chips in the threaded hole!!!!! (I know YOU know that, but remember EVERYONE reads these posts.)

Might check any machine shops or automotive machine shops in your area to borrow one maybe. Surplus store?

Large hydraulic fittings might mean asking a large equipment maintenance shop for help. Places that maintain and repair trucks or farming and construction equipment for example.

That one is NOS from 1981! WOW!

[Peterroy]

Thanks for all the suggestions. Considering the small amount of space within which to work, I like the one from DeKalb that Dave found. New NOS too. Can't go wrong with that or the price.

Thanks again for the suggestions.
