Sorry, we couldn't find any existing installation instruction that matched.

My Dewalt coil roofing nailer, model D51321 was misfiring more often then the drive pin started not retracting.I considered buying a new one.

I replaced the O-rings,as well as the trigger assembly.A straight forward procedure and with the parts from eReplacement parts,they fit without any problems.Parts matched perfectly with the old ones.
I will look to them again for quality replacement parts that fit,when I do the next repair.
