Landing Gear Grease Fitting Sizes?

[corn_flake]

Does any one knows the size of grease fitting on M20E's landing gear?  

My IA and I broke the one all the way in the more recess area of the gear.  Now I'm on the hunt to find replacement.

They are in the parts manual.

And given 50+ years the size is the size find what fits.

They qualify as standard parts, and they're pretty common, so no need to overspend.

The part numbers specified in the parts manual are all available on line for little money. You might as well use the right parts.

The right parts often don’t fit anymore because they were fitted with larger fittings when the original snapped out.

Mooney used these fittings:

It was supposed to attach the whole catalog, but it only did the cover.

At least on the M20J, some were screw in and some were press fit.

LockNLube has a neat tool to extract the grease fittings and retap if necessary. Zerks on my M20C are not standard. 2 different sizes on NLG. Some 7/32" others seems to be 7mm. IDK how metric can be on a 65 American airplane.

Somebody may have tapped it with a metric tap if it got stripped out or something.

They are all in the above catalog. With the exact part numbers from the parts manual.

Thanks guys!!  

Well, I went with the parts catalog and orderd MS15002-1.  Let's hope it works when the broken piece comes out.  Finger crossed.
