Pneumatic Squeezer Overhaul

I have a C style squeezer that isn't squeezing like it should and is probably in need of overhaul. I know Bob Avery used to do that, but I'm not sure if he still is or who else might be doing that.

Any suggestions?

Thanks,
Scott
 
I’ve used Yardstore. They specialize in new, used, and surplus pneumatic aircraft tools and repairs.

I recommend you doing the service yourself. They're pretty simple internally and generally just need the o-rings replaced. You might just pull it apart (take photos for reference as you disassemble it) and measure for replacement o-rings. My old Chicago pneumatics (made back when it was actually made in the US...) uses a harder durometer BUNA o-ring, but you can use Viton as well. Any simple hydraulic fluid will work; I use MIL-5606H, but jack fluid from Harbor Freight will do the job as well. If you have a newer unit, it might have teflon rings as well; both are available at various suppliers. Reassemble with silicone grease and you should find it's working much like new.
