I have five Crosman/Benjamin breakbarrels, and I want to put them in all of them.
Please guide me to the source!
Thanks, in advance!

go to Lowes and purchase a set of brass washers(5/16), put a piece of say 320W/D on a known flat surface and use your finger to rub the washers down to your desired thickness. After that take a buttoned head screw and slide the washers over the thread and lightly lock down with a nut, then chuck this assembly up in a drill and use some of the left over 320 on say a 12 rule from a carpenters square and run down the OD and wala! just my 2c. and for the special touch you drill some grease retention holes around the perimiter.

Same song, different verse. Go to Ace Hardware (if you have one). Purchase a pair of 3/8" bronze bearings for each gun. Nominal thickness is 1/16". That works out to 0.0625" - almost perfect. Put them on a 3/8" bolt and tighten down the nut. Chuck the bolt into your drill press (hand drill will work, but press is easier.) Apply flat file to outer edge until desired diameter is reached. It's been awhile but I think it's about 0.68".
Without sanding them thinner, try them in your gun. They should be very close to perfect. Apply moly on the barrel side where it pivots.
I do not like Lowe's for brass washers. Nominal thickness for 5/16" brass washers is 0.062". I have found some to be thinner than that at Lowe's. Too thin is no good. The pivot screw bottoms out before the forks begin to clamp the barrel.

Make sure that you ask for "3/8" bronze thrust bearings" or else your local salesperson will be confused. Just bought a pair this afternoon.

Are you guys really finding these at Ace?? They just give me a dumb look when I ask for them.

Look in Ace's specialty bolt boxes. It's a set of shelves with slide out boxes. They are there. I bought some from my local Ace.

Man, that is unheard of. A guy goes into a hardware store and ASKS!! How do you know what you want before you've looked around to see what they've got? That's how I found bronze bearings in the first place - and that's what my ACE calls them.

thanks for the info guys,
you are the best. 8)

I used to know where everything was at the local ACE, then they stirred the store. :o :o :o Paint is now where electrical was, roofing is where some of the plumbing was. :o Now I'm lost and have to ask where they put things. ::)

LOL!! When I walk in the front door of my Ace there's about 6 guys standing there saying "what can we help you find". I hate to say leave me alone and I'll look for myself. ;D Now I know better and I'll do just that.
-
Walked into my local Ace yesterday and ask if they had and nuts and bolts and the guy said no. I noticed a lot of big trucks at the front door the last couple times driving by. They went out of business. Found the hex head bolts for stock at the local Rual King.
-
Lowes to get the Hillman brass washers then lathe them down yourself. That is what I did when I had a Trail and performed this mod.

Jerry,
I picked up mine at the Indian Hills Ace on the NW side of Wichita. I would think that the ACE in Andover would have them.

OK, thanks Mort. I did too much thinking last night and got myself somewhat confused about size. I've been using 5/16 brass washers and now you guys are talking 3/8. Which size should I be looking for, and why the different sizes??

Don't know. I have as yet to crack open the Titan XS to even look at the bushings. I would imagine that the ID of the bushing does not matter as the pivot screw keeps the barrel and the frame aligned. The washers are there to prevent side to side wobble and are held in place by recesses in the sides of the frame.
-
Mort, I think I answered my own question. I'll bet the 3/8 bronze bearings/ thrust washers are held to a tighter tolerance than the stamped out brass washers. The bronze ones would have a more consistent thickness vs the brass which is all over the place. Not sure, but it makes sense to me. :P
-
If you go for a brass washer 5/16" is the proper size. The 0.062" thickness is close to ideal but at Lowe's the thickness varies. There is no bin at Ace for 5/16" bronze bearings. 3/8" bearings are 1/16" thick, which is 0.0625". Both are about 3/4" O.D. and will need turned down to about 0.68" to fit.
I put them on a bolt, tighten a nut, and spin in my drill press. I press a file to the side until the desired diameter is reached. If you're lucky enough to find an 8mm washer I have been told to filing is necessary. The outer diameter fits in the gun's recess just fine.
I think stores rearrange stock periodically so customers have to look harder for what they seek. While they're looking they buy more stuff.
-
Yeah Tom, my son and I have done the brass washers on 5 different rifles. It was always hard to find matching thicknesses of them. I finally figured out that the bearings probably had tighter tolerances so I got a few to try. The darn Ace in Augusta didn't stock any so I took Morts advice and drove another 10 miles and found plenty of them at another Ace. Darn near a buck a piece, but that's no step for a high stepper.......right?? I think I'll put the first set in the Phantom, it's the one that needs the most help.

I never had much luck with the Quality at Lowes hardware of any kind . Best to stick with a Ace hardware . Or mcmasters online
-
The first Ace I tried didn't have the bronze bearings, so I measured the 5/16 brass washers they had. Not even useable at around .056-.058, way too thin. Just a heads up to bring your calipers if you have one.

I was told by my local Ace that different suppliers/vendors stock the individual stores. I think that's the reason the variance in the inventory.
Max, yer a sight to behold...........got any sisters?? ;D ;D

my local home town hardware has 3/8" ID bronze washer (thrust bearing) with an OD of 5/8" that are .064 thick for $2 each...gonna give em a shot in a Fury II and see how they do....
-
Dang Hyspd, and I was complaining about my .0625 washers costing $1 ea. :o
-
Just scored some bronze 3/8 bearings from Ace, definitely much harder than the brass ones. However, I still recommend measuring them... they ranged from .061 to .064-- you can actually see the difference in thicknesses. Nothing like fixing a Chinese rifle with Chinese parts. Two issues down( trigger/pivot washers), on to the alive jam...
-
The thrust bearings are bronze-which I agree is harder then brass ; but since the orig. one's on the gun are plastic ...I thought the softer brass washers would work more efficiently !?
Anyone know where to get those Forearm Screw cup Stock inserts that " Gene" used to sell but no longer doz ?
-
Wait, what? Yet another thing I was not aware of, cups for the stock screws. What do those accomplish, keeping the screws tighter and not cracking the stock? Oh, the reason I like the bronze bearings are because they are sintered-- so the surface has small holes in the material to hold the Moly lube. I found those screw cups, they are for the wood stocks only to keep from compressing and cracking the wood.
-
Good Thread fellas,
You've helped lots of us out; BIG TIME!
I like Tom's 3/8" Thrust bearing idea, but that doesn't mean it's the best, just the one I like! ;D
In Kingman, AZ there's both a True Value and and ACE so I have two choices. They both have rows of those pull-out drawers with fastners etc.
Thanks to all of you for the advice.

At first I was using brass washers. One pair from Gene and I made the other pair. Ever since I noticed both my RWS Dianas use steel washers instead of plastic, brass or bronze I switched to steel washers too. Make them to the correct thickness and they should last forever.
