Refurbed the 1377

MigraineMan · Sep 18, 2014

My son and I took the 1377 apart, swapped in new o-rings, and gave it a liberal lube before reassembling. Had to patch the split spacer block, but other parts were in good shape. Seems to put BBs downrange better than before, but it was hard to tell in the twilight when we gave it a test fire ... actually several test fires.

No, my wife isn't home. Why do you ask?

Cool where did you get the replacement o rings. I have one too it won't hold any pressure and needs rebuilt badly. It was very accurate when I was growing up, minute if a sparrow :innocent0

Bought 'em on eBay from seller "anthonysauctions2".

Crosman has the EPLs online, which were very helpful for figuring out how things go together. You'll need to select the correct one - mine has the older rotary bolt cover versus the newer side bolt handle. If you remove the trigger/grip assembly, be very mindful of the safety detent spring and associated ball bearing. Also, remember to re-install them when putting it all back together ... :innocent0

There are a number of disassembly videos on youtube. This one is pretty comprehensive, in spite of the guy talking too much.
