[marty]

Marty want to split fire wood. Was a big beautiful half dead maple tree. Now its a mountain of cut up tree. Ants are having a great time eating the wood.

Problem - There is a bleeder screw on the hydraulic fluid reservoir. Idiot put a normal screw in female part of brass fitting. Original bleeder screw probably fell out and is lost. Splitter works great but hydraulic oil leaks at stupid bleeder screw. Tried some Teflon tape on screw. It still leaks.

Original bleeder screw looked like this:



Note - Knurled part is lost. There is a regular screw in there.

Looking for this part. W1265V0220 SCREW, AIR VENT. Internet takes me to this. W1265V0220 } SCREW AIR VENT } USE ARD23871



Great! Ordered it. Backorder 2 - 6 weeks. Wanted to get rid of my ant infested wood pile yesterday. Give me a little brass fitting and some imagination. Having a issues trying to figure out what thread size this is? Set caliper to mm. Outside diameter of threads is 9.1 mm OD. Open caliper to 6 mm. Measure thread pitch with caliper. Best I can tell is there is 6 threads in 6 mm. So that be called thread pitch of 1 mm. If I am measuring correctly. I have no thread pitch gauges. Fitting also could be inches or who know what? Note this is not a bolt.

Will try this?

That looks like NPT male tapered thread. The teflon tape is the giveaway. Tapered thread is about the only thread that teflon tape (or other sealant) is supposed to be used for, despite whatever handyman hack jobs you come across.
