Good morning,

Thank you for your inquiry. The size of the grease zerk fitting is M6 X 1.0 (pitch). If it is clogged, you can always soak it in some solvent. Let me know if you have any further questions.

Thank you,

But it's not the zerk fitting that gets cloged. It's the hole in the bolt gets pushed hard against the brass bushing.

I guess when you re pack the bearings yoru should pull all the bolts and grease them. NOT.

During assembly,the bolts get installed without any attention to the orientation of the holes. If they happen to end up at 6:00 or 12:00, they will not accept grease. It is a simple matter (usually) to loosen the nut, drive the bolt out far enough so the the knurling is not engaged, turn the bolt until it will accept grease (which means the holes are now at 3:00 or 9:00) and then tighten the nut again. On my trailer the specified torque was 40#. Once done, you will never have to mess with it again. I grease my bushings every 1K-2K miles, which may be overkill, but grease is cheap and replacement parts not so much.

Hope this helps somebody.

I had the same issue with 3 morryde zerks not accepting grease. I removed the wet bolts and turned them 90 degrees. The bolt grease holes should not exit at the top since the grease can't exit to the bushing.
Which is what WNDOPDLR said.

Thanks for posting that, I was just about to ask about indexing. I have 2 fittings that will not take grease. Next time I will be trying that.
