Question about Stanley Bostitch Air Nailer Trigger N60 Fn
I have a N60FN Bostitch nailer. It's loosing air around the trigger guard. I suspect it is the trigger valve. 1. Where is it located and what are the steps of removing it.
2. I have found a TVA6 repair kit on the internet for much less than the Trigger Valve assembly. If the Trigger Valve goes out, what are the chances it can be repaired or should I purchase a new Trigger Valve Assembly?
Any help would be appreciated.
Thank you very much
Your nailer uses a trigger valve part # tva6 (or tva1, but use tva6) (cost about $20) and is sold at www.bostitch.com or ebay for generic. If you have a source for orings, you could try to repair the valve. Remove the roll pin that holds the trigger to expose the tva6 valve. There are roll pin/pins that hold the valve in just above the valve in the body (Use punch for 3mm hole). Remove these pins and apply air pressure to gun to pop-out the valve. Use caution when you do this. Remove nails, lower pressure to gun and use glove or rag to catch valve because it could come out with force. Note the two grooves on the side of the valve where retainer roll pins hold valve. Remember to insert the valve with these two groves aligned with path of roll pins. With tva6 valve in hand remove two pins that hold valve together and remove inner plunger. The middle oring/seal on plunger is cause of leak. Try using an oring with smaller inside diameter than the broken or loose fintting seal that is present. It must fit pretty tight and be slightly thicker than 1/16" to work. Remove the outer orings to valve and clean and re-use same. Clean the valve port in body of gun and check for sharp edges to prevent cutting orings before inserting the valve. Use silicone lube or oring lube on the orings and the valve port (Danco silicone paste sold at Lowes in the plumbing department). Good Luck on your repair and email if you have other questions
