Hi Mark,

The driver not returning is most likely cased by a bad check seal. The seal acts like a valve letting air out of the cylinder. I would recommend installing an Overhaul Maintenance kit. It will replace the check seal plus all of the other seals and rings that typically fail. The kit is part #60079 and is available from http://www.ereplacementparts.com.

Good luck with your repair!

Hi Joe,

The driver for your gun is discontinued and no longer available from the manufacture. They used to offer a driver maintenance kit which included the driver, the bumper and the lower seal. The kit was part #60011. You may try a couple of your local tool stores. I don't believe that this kit has been discontinued for very long. I hope you are able to find one of these kits as the BN200 was a very good gun.

I hope this helps with your repair and good luck!

Hi Magoo, One of three things can cause the driver not to return. 1. the driver is bent and is causing too much resistance as it moves through the nose.After you shoot a brad and release the trigger low pressure ( air escaping out the exhaust) sucks the piston driver assembly up.2. Look closely at the nose guide(This is what the brad travels through as it enters the nose chamber.See if a piece of brad is lodged in it.3 Your bumper is starting to break up and parts of it are getting stuck between the piston and cylinder.Did you take the top cap off and remove the piston driver assembly?Hope that helps.

Thanks i will look at that

My BN200 was doing the same thing. The seal, ref #104, in the cap that the spring, ref # 105, goes against deteriorates and causes the piston, ref # 107 to not work properly. Replace the seal and it should fix the problem.

My BN200V12 just broke on me. The compressor hums and hums but does not shut off and none of the lights light up- no green, no red. Nada. Anybody have a clue as to what the problem might be?

Hi! Most of the parts for your Porter-Cable BN200 are still available, although a few parts are now obsolete. A parts diagram and parts list is available here:

The driver maintenance kit is not available anymore, but that's about the only significant part that is obsolete. I hope this helps!

Much thanks for the help, Mike.

Hi there,
You might not be completely out of luck with the maintenance kit. There is a person on eBay that sells generic brand o-ring kits for a BN200 and several other tools. I have used him for an old obsolete Bostitch framing nailer, ( N16 I believe it was ), that I couldn't get parts for and the o-rings worked just fine. You can give him a shot if you want. link removed PARTS repair KIT-PORTER CABLE BN125,BN200,NS100 - eBay (item 110434137818 end time Nov-11-09 10:41:15 PST) I hope this may help.
