Im looking for feeder spring for a hitachi roofing nailer

I have looked on-line for a local store in cincinnati ohio that sells feeder spring for a hitachi roof nailer. I'm unable to find somewhere that sells them. I have found them to be shipped but all of them take 3 weeks shipping and I don't want to wait..

You can use an oring in place of the feed spring until you get the factory spring. If no supply for orings, use several of the rubber bands that come on the coil nails. Remove the broken spring and streach oring between one side of the retainer pin and the other. If the oring is snugg enough, it will have same spring action on the feeder as torsion spring. Have several torsion springs in stock for future use. Also check the condition of the retainer pin. If the pin shows signs of wear, replace it because a loose pin will allow the feeder to move around too much.

SOURCE: My brand new hitachi NV45AB2 roofing nailer leaks

Take off the back cover and make sure it's not too dry inside. Spray the inside with some WD40. You can take off the top cover. Pop the piston, cylinder, and head valve out, making sure all the seals and rings are seated correctly.Sounds like the piston is momentarily sticking. Does it shoot at all? Lemme know. Please rate me

SOURCE: my nailer leaks air out the back

Hitachi nailers are built on very close tolerences. Dirt /grit will prevent cylinder from resetting causing air to leak out of top of gun. You can force a reset by striking the gun head first against a rubber mat. Only one or two hits because you could damage the head. If the gun does not reset you will have to take apart and clean out grit and replace orings as needed. Good Luck and post again if you have other questions.

SOURCE: my new (used once) hitachi roofing nailer wont

Remove nails and disconnect airline. Open door latch and check for back and forth movement of the feed piston. It should move with little force and should have spring tension when you push on the leading edge of the feeder. If very hard to move then most likely orings are swollen or stuck from lack of lubrication or water entering gun. Remove head being carefull not to tear gasket and check piston/ oring for tight fit( the piston will not come all the way out, just enough to repalce oring). If very tight then all orings should be replaced. If just dry, lube with silicone paste or proper oil. Check that the cylinder retracts into body of gun and rather easily pulls back up. Do not use pliers on the the cylinder; it is spring loaded and shuld move with finger pressure. Parts are available at www.toolpartsdirect.com. Good holidays

Skiping nails


Usually caused by weak feeder spring, however if new spring does not fix problem then check or replace orings on the feed piston (3 orings) , replace the driver oring and make sure that the driver sheet seal is not broken. The sheet is located at the very bottom of the inside of the cylinder area. If good, the driver will not pull out of the gun from the top of cylinder. To see the condition of the sheet, gently pull up on the driver just enough to look down the cylinder past the bumper. If the sheet is missing a piece, air leaks past the driver and does not push the driver all the way back up to top of cylinder causing miss-fire. Good luck

How many rubber washers should my feeder spring have


The feeder pin used by hitachi has a shoulder on one side and a rubber washer /retainer on the other. There is only one groove and the retainer fills the groove and if the correct pin and spring, no extra room to fit an exstra retainer unless the shoulder is worn so bad that the pin is falling thru the plunger. I have seen a lot of creative ways that owners use to hold the pin in place due to lost rubber retainer or lost pin. I also see many guns that have installed a retainer pin from porter cable which has two grooves (one on each side of the pin and no shoulder ). Porter cable pin works fine and fits perfect. Good luck

Looking for a Cental Pneumatic 41209 roofing coiled nailer bucket replacement


Usually the only place for parts for
Central tools is their 800 phone number listed on the document below. That gun was a good copy of the bostitch N12 roofing nailer and also close match to Unicatch roofing nailer. Look on ebay for a photo of the N12 and unicatch. Harbor freight got a lot of returned nailers. Maybe one of the local stores have returned nailers for the ;parts. ;Good luck

I have a craftsman roof nailer with plastic cover for nails broken where can i get one to fit


Best place for replacement parts is the address below.
Ez to order from and usually only takes 10 to 14 days to get the parts. Click on Hitachi logo then select coil nailers, then your model number. For local parts, look in the yellow page directory for fasteners. Fastener companies that sell nails and other supplies to contractors also have parts for Hitachi nailers. Check with several. Some will even repair the nailer for you if you buy nails from them.
Good luck.

Nailer will shoot a nail, but will not foward the next nail. Gun is new maybe 15 lbs of nails or so.


If the nail will not advance, easy test will determine problem. Open door and remove the nails. Lightly tap the nose of the gun against coiled rubber hose or soft wood with door open. If the driver falls to bottom, the piston oring needs to be replaced. The driver should stay at top of cylinder. Next pull back the feeder to rear position and check for tension. The feeder should spring back towards you when you push. Finally, the check paws on the door should return to extended positon when you push on them. Replace springs as needed. Connect air to gun and rapidly bump fire the gun against rubber. The feeder should move back and forward just as quickly as the driver moves. Good luck

My hitachi nv45ab2 roofing coil nailer misfires and only shoots every third nail


Hitachi coil roofing nailer will skip nails if the piston oring is worn, the feed spring is weak or lower bumper is cracked. Easy to check. Remove nails and air supply. With side door open point nose of gun up then down again. If the piston moves up and down in the cylinder, replace the piston oring. If piston does not move and is in the up position, check the feed spring for tension. With air supply removed and door open, slide feeder back and press on feeder from door side to check tension. It should spring back to position against rails.If is feels loose, replace spring and retainer pin if the pin is worn. If piston oring is good, and the feeder has good spring tension, suspect lower bumper and the plastic part below the bumper called the "sheet". Remove head and pull the cylinder to examine lower bumper. Parts are available at www.toolpartsdirect.com. Good luck with your repair

Bostitch roofing nailer wont return driving pin but moves freely


If the driver moves on it's own then it's o-ring is shot,replace it. Pop the feeder cap and clean all the roof crud that's built up underneath it.Now you can see the feeder spring,check to see if broke or old and replace.The feeder plunger is air assisted so hook the air up and depress it, it should depress hard and pop right back up. If not it needs to be cleaned and new o-rings. If this doesn't work then it's a new feeder plate you need. good luck.

Nails


Yes there are many different kinds of siding nails from all over the world. Stores that sell nails buy/import nails from where-ever the labor/cost is cheapest. The importer uses a private label so the nails from one company in China will produced according to requirements and will be sold under many different brands in the US. The result is that the nails are not exactly the same from batch to batch. I have seen coils that measure from 3/16 to 1/4 inch between the nails. Closer to 1/4 inch is more ideal for your nailer. The (nv65ah) is listed as a 16 degree canister angle, however you probably purchased 15 degree nails because nothing else is available. Should be no problem assuming everything is working ok. When you insert nails into feeder, make sure that the first nailhead is positioned under the driver and not too far to the edge because the driver will bend the nail if not hitting dead center to the nail shaft. Ask for a sample section/ roll of different brands and type of nail to find the best nail for your gun. Best place to find nails is a fastener company that only sell nails/ nailers/compressors to contractors. For best results, make sure that the driver is squared/flat at the tip. If is not, remove the driver and grind it flat (do not grind too much). If driver and nails check out ok, then it may be time to replace springs/orings in feeder area. Go to www.toolpartsdirect.com and take a look at the breakdown of your gun and notice that there are several springs in the feeder area that will weaken over time/use. There should be two springs in doorlatch area, one on the feeder itself, and one large spring pushing on the feed piston. Good luck with your issue and email if you have question.
