Ok... my 1377 makes a kind of creaky sound when pumping , at the end of the pump movement , right before closing the fore grip against the tube . I think is the friction of the piston , so I put a couple of drops of Pneumatic oil on it but the thing keeps creaking . Is that normal ? The gun works ok and fires well, with no issues ... I am just curious as to if this is normal . There is also a little bit of play on the pumping mechanism , right on the big pin at the end of the barrel . It is not the pin which is hold tight but on the pumping lever the the pin holds ... if I open the lever to pump and I move it slightly sideways , there is play . Can I insert a washer of some kind to eliminate that ? I wouild like to get the pumping lever to just move up and down with precision , with no sideways play , if possible ... Thanks
its the check valve making the noise
try a different check valve.cleaning it doesnt do any good you can try to mod it but cant say if thats going to change anything
its one of those weird things that happens some do it most dont
Or loosen the piston setting up a bit. That took some of the creak out of mine...just dont over loosen it!
If the pistol shoots well, ignore the noise. As 1377x stated, he had this problem and the check valve caused the noise, possibly from a slightly out of spec part or the way it seated against the valve spring. I have had a variety of squeaks; some pass while others are chronic.
As to your pump arm wiggle, that is common. Some have had some improvement by slightly bending the two tangs at the end of the pump are with the holes for the roll pin. A very good idea would be to order a replacement pump arm pin from Mellonair. Why? Well, first, he supplies a washer that fits betwen those tangs to help reduce the wobble, and second, removing the pin is 1000x easier than banging a roll pin. Probably would be the best $8 you spend on the gun.

TOTALLY!!!
all the 1377's ive owned have made that sound. no noticeable issues.
I just ordered the solid pin kit with Charlie by Paypal . Any idea of how long waiting time will be ? he seems pretty busy .
I will forget about the noise ... no biggie . The wiggle at the end of the pump arm , however , it bothers me . Hopefully the kit from MellonAir will solve the problem .
I have to give this Forum a high mark , guys ... Tremendous help , great advice and tons of information ... I am glad to join with such good company .
If he has them in stock,may3weeks . That was for mine If not 3 to 6 weeks ??? Hard to say. Just forget about them and one bam they are here LOL
He is now working on orders in the order they were received. Today he is working on 16 September.

No, I got all the information from his web site.

I got my first order (Jul '12) in 3 weeks. Starting 23 Sep '12, I made six orders. I received order #5 (barrel) almost immediately. When I looked on his web site he posted that he had no more barrels and was now filling orders in order of receipt, and he posts what day he is currently working on. I hope he gets to my orders before he gives up and takes a vacation.
Well, I can understand if you order a custom part that has to be made specifically , like a valve or a hammer or a barrel , etc , you would go into the wait line , but if I order a solid pin kit that most likely is in stock , I can`t see why I would have to wait 3 to 5 weeks ... it just seems not right if you ask me ... just saying

All his parts are custom parts. They are so popular that he can not keep up with the demand.

That's very true. Same goes for Don Cothran...get in line :D

hate to say it, but you can expect this as the norm for most airgun parts purchases. not saying I don't agree with you, just speaking from experience from a couple different sources. my guess is that most parts mfgr's recognize this is our hobby and since their parts making venture is probably a side business, I haven't found there to be the sense of urgency you may see from other vendors.
unfortunately, this isn't amazon.com.
I guess that`s how it is ... unfortunately, we need the parts , so no way around it .
i do not remember mellon being so frikkin busy. maybe its because of the time (hunting and holiday season)

that and when accustoms stopped making parts mellons work load went up
accustoms had competitive prices with mellon and everyone else has double priced items.they domibated the market.now these other guys are getting business back because mellon is so busy and people want their parts now.hope that doesnt result in mellon raising his prices like airgunsmith did his
