Trigger Valve Kit TVA6

First thoroughly clean your nail gun [ I use various little brushes, compressed air, carb. cleaner, rags and then air tool oil ]. Set up an area with good lighting and work over a surface where you will not lose any small parts. "Cradle" the nail gun on some rags and carefully use a hammer and a small straight punch of the correct size to remove the roll pin that holds the trigger and its spring in place, next do the same to remove the roll pin that holds the valve assembly, make a bag full of rags as a "catchers mitt" - put this around the trigger valve location,put on safety glasses or face shield , briefly attach the air hose at less than 90 p.s.i. !!! [ start at a lower p.s.i. ], this should pop out the old valve assembly into your "catchers mitt". Inspect that the nailer is clean inside this opening, lightly oil this area, Apply a uniform thin layer of grease to the valve assembly then make absolutely sure that the new valve goes in "square" / straight to the opening and that the retaining pin hole lines up with where the roll pin must go back [ USE THE SUPPLIED ALIGNMENT PIN TOOL ! ]. Gently reinstall the roll pin, make sure the trigger and its spring are clean and reinstall these and the retaining roll pin that hold them. Of course visually inspect everything along the way : that new valve assembly is complete [ o=rings in place, no housing cracks in gun frame, no debris inside gun, etc... ]. *** using too high of air pressure to pop out valve during repair can hurt you or others - as it will fly out like a bullet or shatter plastic parts ***

Use punch to push trigger pin out. Remove trigger. Hold rag over trigger valve, connect air for brief second which pops valve out. Oil new valve liberally, replace in pocket careful to line up correctly. Replace trigger and pin. Done

1.Took pin punch and removed pin that holds trigger and spring in place.
2.Removed trigger and spring.
3.With pin punch removed pin that held trigger valve in place. Didn't drive either pin completely out but drove out just far enough to remove trigger and trigger valve.
4.Removed trigger valve by using a small awl to force out. Instruction say to hold rag over it and hook up to air and let it force it out but it came out without any problem using awl. I wasn't worried about damaging valve since I was going to be replacing it anyway.
5.Lubed new valve assembly, cleaned trigger housing and checked for burrs, and reassembled
in reverse order.
6.Works like a new gun. Complete repair including tear down took less than 30 minutes.

Using a small hammer & a flat bottom punch, removed the roll pin holding the trigger in place. Using the punch again I removed the roll pin retaining the trigger valve,& covering the old trigger valve with a rag I hooked up the nail gun to the air supply & it popped out the old trigger valve into the rag. Using the supplied grease I lubed the o - rings on the new trigger valve & installed it into the gun, & then reinstalled the roll pin retaining the new trigger valve.

I followed the instructions that were included with the kit. The repair was completed in no time.
Thank you for the quick delivery.

I opened the package, followed the step by step instructions, used the long pin provided to push out the pins holding my trigger assy (I also used a hammer to drive/push the long pin - the instructions didn't suggest this.), used (some of) the packet of grease supplied, reassembled the tool with the new part and now everything works like a dream. Things took me longer because I'm a bonehead and took the trigger apart. Do NOT take the trigger apart - it has small parts that are assembled by people with 6 hands - a total PITA.
I will definitely use ereplacementparts again.

1. Drove out the pins holding the trigger and the trigger valve with the enclosed pin driver.
2. Pulled the trigger valve out gently with the pliers.

4. Slid the new trigger valve into place.
5. Reinstalled the pins holding the trigger valve and the trigger.

2. Remove the trigger and spring and set aside.
3. Remove the roll pin holding the trigger valve in place, pay close attention to the position of the trigger valve.
4. Carefully attach the air hose to blow the trigger valve from the gun.
5. Lube the o-rings of the new trigger valve with the included lubricant.
6. Insert the new trigger valve, paying attention to the roll pin location.
