I think I broke it.... How to rebuild my G1???

<< < (2/6) > >>

Bentong:
Springs and seal are consumables. That's all I've used on my G1 & Sierra Pro to bring them back better than specs. I always order spares from crosman for they're cheap with fixed $4 postage. When decompressing your spring, place a piece of wood on the low side of the plastic plug to your compressor. The plastic will crack before you can take the pin out. Just don't forget Newton's 1st & 3rd law of motion so you don't get the 2nd law like Mike.

the crossman springs seem to be pretty decent actually... see the things with springs are is they break :) doesn't really matter from who they WILL break LOL a good tune will prolong the life of the spring along with a good diet of appropriate weight pellets... other then that seals and springs are consumables they eventually wear out.. (seems the average is around 5k or so before failures but that varies so much too LOL)

well with your background I would suggest finding some good articles(check the library here there are some great articles on tuning) build your spring compressor and then get your hands dirty :)

yea thats a good point there... I took a peice of 1/2" copper pipe cut it to length and then flattened it out till it filled in the "step" on the back plug that way the force is acrossed the whole peice of plasic and not just on the top part....

oh and yea... the 2nd of newtons laws can be a b$$ch LOL!

Springer25:
Thanx for the tip guys.  I plan on building the compressor here shortly.  I just took a picture and the spring looks like it broke and coiled around the other one....  

Springer25:
Well Here are the damage pics...  I didn't even have to use a spring compressor to disassemble.  Just observing that the spring was broken multiple times.  I still took precaution and  I first tested to see if there was any pressure on the spring guide assembly and it was just floppin around...

The spring was not only broken multiple times But it also was twisted


One good thing was my seal looked to be in good condition no tears frays, etc
