Want to get a 90 degree zerk fitting for my 08 Uultra classic. Does anyone
know what the thread size and depth is? Thanks

 

Did this last wwwk. Took out old fitting and went to Auto Zone. There were only two size fittings, multi, in small boxes, one fits the other too big. By the way, how much grease?

 

It's 1/4-28. Get the multi pack. You may not be able to get the 90 degree in. If so, use a 45 degree.
You may also have to get a different tip for your gun.

 

45 worked best for me.

 

Me too.

 

45 here too, and didn't have to change tip

 

45° works the best. Hard to get the grease gun on a 90° zerk

 

I just today removed a zert on the neck of my 08 RKC, and installed a 90 deg.
I had one!!! Ever now and then a plan comes together......I emptied what was
left in my hand pump grease gun and loaded a new Aimsoil tube and pumped
till it had right much resistance. Never did get it to exit at either end, think I
should pump it till it BLOWS????? Tenn.Vol.

 

Actually its a 1/8 inch pipe thread.

JUST DOUBLE CHECKED< I WAS WRONG- It is a 1/4-28 straight thread not a pipe thread, as I thought.

 

I'm gonna buy one of these, http://www.sjdiscounttools.com/the418.html
