Going to pump my C362 to 7 pumps max, but will using 8 pumps hurt it ? The brochure says 8 pumps max, but is that true, will 10 pumps smash a seal or ? As I stated before I'll be using 25-29gr ammo
For me 7 pumps is what I want as my max and 5 pumps as a standard with lighter pells for fun.
What are your thoughts on hurting the gun with 8-10 pumps ?

I'm sure there is a safety margin built in. Over pumping on a gun that was not beefed up for it just puts extra strain on the linkage, pivot pins and the holes for those pins. It also puts added strain on the screw that retains the valve.
At the end of the day... it's your gun, you paid for it, treat it however you want.
For me, I live by the rule.... if the gun I have is not up to the task at hand I will go in the house and get one that is.

Ya, that is why I said 7 Pumps is my max pumps --- just wondering about more ?

Understanding the issue of the 392s and its not so strong pumping arm leads me to believe that I should and will stick with the specified 8 pumps max to prevent premature failure and will do the same staying below or under the 8 pumps until the 1 year warrenty expires and aftermarket pumping arm and other beefed up components come along, then is game on.
However, for those already making changes the warranty does not matter, I am glad they are in this position to make modifications sooner rther than later as it allows me to learn what future modifications will be most effective beyond a steel breech that I may want to make. To these members I say thank you for leading the way as I am looking forward to what is possible.

As long as the guns properly lubricated, you should have no problems with the C362 linkage at 8 pumps. We recommend one drop of pellgun oil every 250 shots on the Pump lever pivot, linkage rivet, and piston pin. This procedure is followed when this gun is cycle tested to 10,000 shots w/8 pumps. (Yes.... that's 80,000 pumps.) Proper lube goes a long way. jk

There you go. Straight from a Crosman engineer.

That is exactly what I wanted to hear --- Thank you very much !

Let us know when you get to 80,000 pumps. Yikes!!!

80,000 will pellgun oil. I wonder how long it would last with some moly lube? I'm getting tired just thinking about it. 😁

Moly lube is the best, and a little of that can go along way and it can be mixed with nd30wt oil.

I have been working moly powder into the pivot points Should help with long term wear, the piston gets pellgun oil. Happy with the 7 pumps, in overall performance, kind of a sweet spot in many brands of pumpers.
I better order my next 362, I'm already 800 pumps into this one LOL, the next one gets the mods, so wont be long :)

You're not kidding. I bought a small jar back in my springer days (early 90s) and still have most of it left.

I have pell gun oil here, I think I'll go with the engineer's suggestion... ;)
Who would know better than he?

I'm thinking about ordering 2 from the start. I should know how long my wife's hospital stay will be by tomorrow, so it should be soon.

No warranty for me, I barely had a hundo of pellets thru it before taking it apart and putting lube in the trigger pack (SHAME on you Crosman for not lubing anything in the trigger pack!!)
Seriously, completely dry, just a touch on the bolt sear but all the linkage was dry. >:(
I took her to 10 pumps and got a clean 700 FPS with a 14.3 gr CPHP, that is pretty nice but I'll use 8 pumps for the 675 fps as it seems it plateaus at 8 pumps anyway.
-
Is the trigger in this better than the one on a 1377 or 2240 ?
I have asked this q on another thred but no replies there.
Hope to get an answer from you.

My last 1377 was purchased in 1990 so It's not a fair comparison for me but I did find my 362 to have less slack and a crisper let off, the 1377 was/is spongy and hard to guess when it would break.
The good news is that even though I got some very rough parts in my trigger group, a little work on the contact points, a tiny dab of molly and a simple spring change gave me a sub #2 trigger and a nice crisp break. It's no Geissele by any means but it' serviceable.

Thank you so much for your reply. So it is better than a 1377/2240 trigger.

Apples and bananas, it's a complete different monster.

Maybe I got a Monday trigger group on my C362 but it was horrible at least by my standards. Followed Bill on his trgger mod and put the Baker brass trigger in with a spring mod as the Baker spring and screws won't work. It's a dream now compared to stock. See the thread this is my C362.
-
I've got a small hone stone I found digging for metal with my metal detector and sure have made a lot of use of it for a long time now on especially any steel that needs good polishing, it does wonders on trigger mechanism's.
-
Exactly what I used Wayne. I have them in 4 graduated grits from my tool and die days.
A knife sharpening stone is also useful to get that mirror finish.
As for it being my trigger mod... not so much, I think Van was the first one to bring the oversized spring to light.
I eluded to his mention of it in the fist couple posts in my thread.

This gun I built from a 2200 tube with 2200 pump linkage and Mountain Air flat top 1377 valve with extended pump rod has been pumping up to 12 pumps for years when hunting with no problem. Does the 362 have weaker pump linkage? The tube is shorter than a 362 by a few inches but still gets 670fps on 8 pumps, 705fps on 10 pumps and 725 on 12 easy pumps with 14.3g pellets with this setup. Just added a Melon Airgun flow through bolt that added about 15fps to the 12 pumps shot over the usual Disco bolt. I thought the flow through style might get less FPS but it got more on every gun I changed out. I would think 10-12 pimps should be fine on occasion if kept lubed. I use Mac1 Secret Sauce on the rivet and my solid pivot pin in front. The 362 should be just as strong as a 2200 pump linkage unless the extra length of the arm is a problem or not supported by a hollow synthetic stock. (http://)

That's the same number I got with 10 pumps using CPHP's.

Sounds like the Mountain Air Flattop set up with the longer threaded rod extension would make some serious power at fewer pumps then with the extra swept volume of the 362. Going to have to try that just add a longer threaded rod if necessary to take up head space.
