Permanent lubrication for machine heads

Both Grover and Kluson now make solid units that don't fall apart. The new Klusons found at Stew Mac are a transformed hybrid, I wouldn't want them, but they're there, for anyone's consideration... http://www.stewmac.com/shop/Tuners/Guitar,_solid_peghead_tuners/Kluson_Waffleback_Guitar_Machines.html

The cover on the tuners that I believe you are referring to are shown here with arrows, and they just crimp on in 2 places. In the middle pic, it shows a slot or gap beneath the hole, and that is repeated twice to secure them.

In the bottom pic, the second or bottom crimp goes through the base right under the "PP".

Let us know if that's not what you meant. The gear inside just screws into the post.

I think a good white lithium lubricant, or regular grease works well, inside. :)

And the two tabs that are bent or crimped are seen on these bottoms.

I don't think those unsealed Klusons are meant to be "permanently lubricated." I trickle a little gear oil in them now and then.

Agreed, the oil goes into the hole, as you've been doing. I use a PTFE Microlubricant from Radio Shack or the Source.

The question was a little ambiguous but reasonable, and if they ever come apart, you can put some heavy stuff in there, if you seal them up again, or reassemble the pieces. 8)

Gotoh has a version of those tuners - the SD510 - that is permanently lubricated. They work great. They also have them in a locking version SD510MG (Magnum lock). The SD90 tuners on the same page look similar but aren't permanently lubricated.
