Anybody got a pic of a valkyrie ujoint that has the cap off?

How hard would it be to put in a drill press and drill a hole in each cap and tap to put a zerk in? Once greased, unscrew zerk and screw in a plug.

Wouldn't it require one drilled into each cap, and after greasing, why remove? With 4 it should be balanced, and even with one in the corner of a universal there is no thought of being out of balance.

I dont think the ujoint is cross drilled. If you leave the zerks on, they may stick out too far.

If the cross is hollow you could just drill into the center of the cross and install a zerk fitting just like the do on automotive applications

I have no idea if the ujoint is hollow......???  If I had a ujoint with the cap off, I could see if it was hollow.

Most u-joints are hardened, making drilling and tapping a challenge.

Will this work? If you can see it in the picture the center is NOT hollow.



I thought the bearings on this end cap would be toast when I pulled it apart but they looked ok, this is the cap that was spinning inside of the yoke, original u-joint with 32k on it. It had a clicking sound I heard just pushing the bike back and forth in my garage. New u-joint installed, no more clicking sound.

Hope this helps.

Thanks Magellon,
From the pic, it looks like the indention in the T is about 1/4" to 3/8". If the caps are drillable and tapable, there may be enough room for a zerk. Grease would reflect off the indention, fill the cap and ooze out the seal. Only problem I see is the fact that there probably will get metal filing in the cap. You could use solvent to wash it out really good, maybe use a little teeny tiny magnet, and then grease the snot out of it. HMMMMMM

FWIW I had a modified yoke on my I/S trike.  The joint used was the part used in the  "my rebuildable u-joint  linked at the top of the page.  The grease zerk was in the cap & it rubbed on something.  Had to replace it with a plug & replace the zerk when greasing.  The swingarm on the trike was different than stock, so this might or might not be an issue.  Stan

 Most U-joints are not able to be drilled with home tools. A sealed U-joint will not have a drilled cross. Another option for a grease zerk in a grease able U-joint is a needle fitting. It has a small ball bearing opening that is nearly flush mounted. It is greased with a needle like attachment on a grease gun.
