Demon drive Z-link slop

[bbeyer]

I have a double demon drive pedal.

The u joints in the driveshaft (z link) are awesome, and have NO slop in them... However, the roll pins that secure them to the shafts, have slop, which is a silly thing.

I figured id drill them to the next size up, just a hair.. and get a machine screw through it.. or find a slightly larger roll pin.


anyone else had this issue?

I don't own a demon drive pedal, but if the problem is as simple as some worn or wrong sized roll pins, it's an easy fix. If Pearl won't send them to you, they're easy to find and cheap at many hardware stores. Chances are, either the roll pin or the hole are worn.

Im pretty sure the holes are worn, and its an easy fix for me.. I just wondered if it was happened to other pedals out there

So I took this thing to work and decided I'd drill the things out and put some 4mm bolts and locknuts through where the roll pins were.. I was a little small on my holes (my drill bit set isn't metric so I went to the next size down thinking it would be good to be snug)
Well, it got a little too snug and seized the 4mm bolt and subsequently broke the bolt.
No biggie.. I just repeated the bolt insertion and snapping on the next side, and cut them with a rotary cut off tool

Now if only this shaft would work on my dw pedals..... (I plan to run the demon drives as two singles with double bass drums)

Dang! Pretty good work. You may have very well permanently fixed the problem. The only downside will be if you ever have to re-do this. If so, you'll have to drill out the bolt and that could be a mess. A roll pin would have been an easier fix. But I'm betting your fix will outlast the pedal (and possibly even the drummer)!

you should check trick percussion,,,,,,they offer the whole shaft assembly off there pedals ,,they have different versions for different pedals

I believe that this shaft was actually designed by trick. I read somewhere that pearl paid them for the design or something.

Nice Job!

hmm .. if its true it wouldnt surprise me ,, for example : many of the tama iron cobras features were paid for by tama to dw , for the rights to use patented design features,, like bearings on the hinges and such

It worked out that this shaft WILL work on my DW pedal. Even though dw uses the square shaft and pearl uses a d shape, the fact that the pearl shaft has dual set screws where it attaches, makes it feasible
