Anyone know when removing the wick on the rear of the crankshaft of a Detroit 2-71 that lubricated the clutch pilot bearing, is it a 1/8 or 1/4” pipe thread or something else? Freshening up the clutch and want to remove it replacing the open pilot bearing with a sealed bearing. Loader is 150 miles away to check. Thanks.

It's NPT - or plumbing thread -
Then replace pilot bearing with a sealed bearing (pre lubed)
Did that on mine back in 1972 when I bought my machine
