Is there anyone near the Ann Arbor MI area that works on old Crosmans my July 1976 1400 seals went. I would really like to get it repaired local if possible so I don't have to mess with shipping. If it isn't to difficult to do myself I would consider that too. Also will I need to replace the valve too? The gun is new in the box it has only had 4 or 5 pellets shot threw it. Thanks Tim A

givin it a nice shot of oil try to pump and shoot it through. sometimes that's all they need.

Tried that seem to work for a couple shots then started leaking again. I'm gonna try it a couple more times but I am afraid after 30 years of not being used seals have went bad. The gun is brand new it has only had a few pellets ran threw it.

You may be able to send out the valve and pump pistonhead for a rebuild. These are not hard guns to work on.
AB airgun, Precision Pellet and Mac-1 are my preferred airgunsmiths. Dave

Do you know of any online instructions other than just schematics I think I could do it with a step by step guide. Thanks Tim A.

Another airgun blog. These guys do what I wish I could.
Follow the links. The 1400 is an updated 140, essentially the same rifle. Dave

Might check their site to see if they have a kit for the 1400.

Bought a reseal kit for for my father's 1950's Benjamin 310 from them and the kit contained step by step instructions as well as a photocopy of the original owner manual with a complete parts list and the valve tool needed to work on a Benjamin. With the instructions in hand and a couple questions posted here when I hit a snag, it was a pretty easy job.

Great guy too!

Sometimes they sell the 140/1400 Seal Kit at A "Buy it Now" Price of about
$35 Unless you can get Precision Pellet Kit for $20 Has all O-Rings ,Plus
the Quad seal,that comes with Blow-off cap! Like Dave sais, these Guns aren't that difficult to work on! For the Transfer Port Seal,use 1/4"O.D. Ice-machine Poly tube,Use Only a few drops of Pellgunoil at joints where Pump arm ,felt wipe(on Piston Rod) & trigger housing & Breech Probe o-ring!
