Modifying the "Slave" DW 9002 Pedal
Posted On 06/04/2008 15:14:08 by nullmuse

This entry is to provide information to anybody out there who already owns a DW9002 double-bass pedal.

If I were buying the pedal again, I would buy the 9002ACS which is infinitely harder to find, but has the footboard as one entire unit thereby eliminating the heelplate.

I bought the DW9002 awhile back, and thought to myself, "Now I can play double-bass on one drum, and if I ever want to, I can always use this second pedal as it's own 'stand-alone' pedal or use one on each drum!"

It turns out that's easier said than done! You can add an additional beater to the secondary pedal and use it on a second drum, but because the "secondary" or "slave" pedal derives all of its spring from being connected to the primary pedal, if you ever intend to SEPARATE them and use it on it's own, you're going to need a whole slew of additional parts.

Unfortunately, the parts list for DW pedals is quite involved, and they're all written from the perspective of the "primary" and don't consider modifying the secondary pedal to stand-alone. With the benefit of hindsight, I would now just tell anybody who wants to modify the secondary 9002 pedal to look at the manual for a DW5000, which can be found online at the DW website.

After researching it on my own and talking with the guys at the drum shop about it, I even contacted DW Customer Support. They were immensely helpful and gave me good information, and they also pointed out the "modified" pedal would feel more like a 5000 than a 9000.

The way it turned out, I STILL needed additional parts beyond what DW Customer Serivce originally told me I would need. So, to benefit future generations and hopefully save some trouble and heart-break, here's my list of parts (what they cost me in June 2007) and a brief explanation of what each part is FOR in case you decide you want to make your DW9002 secondary pedal stand on it's own.

  • DWSP032 T-Screw for Toe Clamp - This is the handscrew you would need put underneath the pedal to clamp the "tongue" of the pedal to the bass drum hoop. I don't move mine often so I just tightened the locknut and the alan wrench screws to hold mine in place, otherwise you'll definitely need this to easily tighten and loosen the pedal from the bass drum. Sorry I can't give you a price on this.
  • DWSP025 ($21.00) Spring Assembly - This is the entire spring assembly for a DW 9000, which is actually composed of about five or six different parts. Ordering them as one part ensures you will get all the nuts and parts you need.
  • DWSP066R ($4.95) Stroke Adjustment - The 9002 has an "axle" that connects one side to the other, this is how the "secondary/slave" pedal gets it's spring from the primary. Since you're not connecting them, this is how you're going to connect the axle to your springs. Because this part is powder-coated, you might need to use a small file to clean some of the powdercoat out of it's hole or even use a rubber mallet for some gentle persuasion putting it on, but I assure you "it fits", and BE CAREFUL not to damage your axle putting this part on!
  • DWSP018-3 ($9.99) Rocker Hub - Sometimes called a "Turbo" Rocker Hub, this is sort of a hoop that goes through the loop at the end of the springs. The bolt below connects to the Hub and the Stroke Adjustment, and allows you to bolt the Stroke Adjustment to the springs without torquing the springs each time you fire the pedal.


  • DWSP015 Slotted Screw - This is the bolt that holds it all together and connects to
  • DWSP061 Square Nut

I eventually went to the hardware store with my various parts and simply found a bolt and nut that would do the job, but I -did- eventually figure out what the parts I needed were and have written them down here to help you!

Note that the DWSP015 bolt is not threaded all the way to the head. My total cost for the nut and bolt via hardware store was under $3.

Below is a picture of the 5000. I supply it for two reasons--

  1. You can see what it looks like when the footboard and heelplate is one unit. This is what the footboards of a DW9002ACS look like as opposed to the DW9002 with the standard heelplate, and
  2. You can see the axle, spring assembly, and everything else on the right side of the pedal. This is what the assembly that can make your 9002 it's own stand-alone pedal looks like when it's completed.


I hope the information helps. Best of luck and Happy Drumming!

I wrote this to help other people with the same issue, but writing this entry helped me work it out...until now nobody, not even DW Customer Support, explained it as simply as "You're going to need to slap the spring assembly from a 5000 on it" which is basically exactly what you're doing.

Thanks for the comments!

Wow!! Thanks a lot for this amazing guide! Modifying ANY drum pedals is usually a pain if you dont have a shop full of parts behind you! But you lay it out so well it feels like it is not such a big deal and can be actually accomplished pretty easily!!

Thanks again!
