I have a Benjamin 312 and need the rebuild kit. Does anyone know if this kit will work. I'm sure the 312 I have is at least 40 years old.

Yes I was able to repair my Benjamin air rifle with the kit. The plunger on my Benjamin had dried and cracked and the plunger in the kit fit perfectly.

There is a kit available for pre 1995 Benjamin models when they used the soldered valves. I did some research and I am not sure if all the parts in the kit would work in the model 312

Hey Roy, I've never seen that on a BB. Is the old BB a three piece design? If you're moving to a cartridge style you'll have to measure, but likely a 118mm or 123mm spindle length will be what you need. Read this page http://www.parktool.com/blog/repair-help/chainline-concepts it will help.

You probably just need a new cup for the recoil starter. Sometimes, they come with the recoil starter sometimes not. It should work if you have the one to mate up.

You can look up your serial number to find the part number or part numbers of the parts in the kit. Look at the pictures to compare the parts. As long as they look the same they should work.

Ask the seller, & I believe they have other kits. If not there are others available, google the number.

If your Benjamin has a dovetail, it will work. If it has a piccatinny rail these aren't needed. Some do some don't. Google dovetail to see what it looks like, then piccatinny to compare and see if you need them.

I believe I had to get a fitting from Pyramyd to attach to the end of the hose so that it could be used on Benjamin. My memory is fuzzy, and I no longer have the pump...

The Leland cartridge in 2 7/16 in length. and should work fine in your Benjamin . Other brands available are 2 9/16 in length and may or may not fit. I suggest you try the Leland first. I tried several before learning the leland cartridge worked best in my restored 1960's Plainsman. Ron

I am not a small engine mechanic. It has been a while, but from what I remember it was a simple process. It comes as a kit. You take I believe for screws out. Take broken recoil off. And the new one is easily replaced. I was surprised. That is what I remember. Also, the Recumseh has worked very well since it was replaced. 2 years I think.

Yes. Amazon, air pyramid, walmart and many others sell the special mount kits. The part # is B272.You do have to use these special mounts designed specifically for a Benjamin.

They only sell the complete kit. You might try looking on ebay or a salvage yard but your chances are slim!

Not enough information, look at the rpm on the old one, it probably won't be exactly the same as the new one,but that's ok, as long as it's close within 100-300rpm is ok, I recommend Buying the fan too as the old ones are tough to get off, the set screw breaks inside, this happened to me twice, again, look for your RPM'S and Voltage

The reason I bought the 357/303 was to replace the LR44. The 357 / 303 is working fine so far.

That would probably not be worth the effort. It operates at different pressures so it may need some other mods too; and likely not be as cool as new. R290 comes up in a search at as replacement, but its flammable. The R22's oil wouldn't be compatible with r134 either.

I can't say for certain that this will fit a Benjamin 312 but it looks like it would. I would not think the barrels would be much different in diameter than the 392 or 397 barrels. You could always return it I guess.

if you have the old style or AMERICAN style, that is NOT threaded inside the frame, punch out the races and use the TRUVATIV BB conversion! YOU WILL BE VERY HAPPY YOU DID! There are a TON of videos on how to do this, check out bikeman (I think that is his youtube handle) and you wont be let down! JUST MAKE SURE YOU INSTALL THE DRIVE SIDE PROPERLY AND LINE UP THE CONVERSION BEFORE YOU SEAT IT INTO THE FRAME! The screws to the conversion will pull it TIGHT but make sure it is in far enough to not strip the screws or adapter! THIS BB is one of the best values in the industry! I dont recommend any UNDER this model, even though they are VERY RELIABLE. THIS is a small price to pay and while you are there, I recommend an upgrade to your crank set to bring you an upgrade that will breath life into that nice HARDROCK! IF YOUR FRAME IS ALREADY THREADED, no worries, this should work!

My 430 is two months old, used 30 min 4x week, and has developed that knocking sound - that's why I am on this site, looking for advice. Looks like a tech call is in my future. I'll report back.
