Need 2 custom fit sealed bb to new rt bearing cup being made for me. Comparing the 122.5 and 127mm, are lft/rt lengths 50/50 or rt longer, as needed?

lft/rt lengths are 50/50 on the 2 bb's I bought. Not sure how to how to adjust for that. Maybe by using a spacer between the frame bb????

You need to buy a longer BB to account for it. I'm going through the same issue. What I haven't seen a comment on is how this affects the non-drive side. Would you notice it when pedaling, especally if you "clip-in". This chart gives you the symetrical equivalent - http://sheldonbrown.com/bbsize.html . My 3T spindle would need a 130 symetrical BB.

The bearings consist of two sealed cups that thread into the bottom bracket on each side. The crank is attached to a hollow shaft that slides through these cups. This design is called Hollowtech II by Shimano. I'm not sure about the width, as it may work for a range of widths. I used this to replace a 68 mm English threaded BB on my 2008 Specialized Hard Rock XC Disk and it worked out well. It comes with plastic spacers that allow you to adjust the chainline (distance between the seat tube center and middle chainring). I believe all of the spacers must be used, but you shift the cranks side to side by changing the number of spacers under each bearing cup.

The kit includes the 130-036 and complete 1322-013 assembly, ready to install. I suggest ordering an extra 130-022 (the o-ring sealing air to the pellet) as well as an extra 130-035 (o-ring on end of valve assembly), and a 760-140 (piston cup) . If yours has a metal ring retaining the pump handle - piston assm. - to barrel, order a roll pin 130-030 (available at many hardware stores 9/64 x 1 in.) or replace with standard snap ring. Be sure to sand the inside of the pump chamber using 220 grit sandpaper flaps stapled to a wood dowel to remove burrs which will damage the new soft parts. Watch several of the online videos to get repair info. Talk with the parts guys at Crosman, Toll free: 800-7AIRGUN (724-7486) they are quite helpful. Are the trigger and sear in good shape? Good luck.

130mm BCD is the spacing. It did not work for me. I wound up getting a new crankset, which also required a new lower bracket with longer spindle. It all worked out in the end.

this one is a 5/16 24 bore , check the thread size (24) . I hope this helps.

This kind of bottom bracket is different than the older type with two separate bearings. it's referred to as J.I.S. Japanese industrial standard. I used a little heat on the BB to be easy on the tool and it worked for me.

Get the Wolff Xtra trigger spring to make it worthwhile. That's the only way to get it down to a 3.5 pull. Connector leaves you with a 4.5 pull

The 19B is designed for 2" Outside Diameter (OD) bearing assemblies. Sizing of the Bearing Buddy is not determined by tire/rim sizes. Check OD of your bearings.

I believe the 15" should work fine. My 5 1/2 " barrel is 11" long. I got the 13" and it's a perfect fit. I assume a 7 1/2" barrel should be 2" longer, so a 15" makes sense.

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.

UTG high 30mm rings or GGG high 30mm on my RRA Operator it barely cleared the barrel. Mediums would not have worked.

I am using my engine for a custom built hydraulic log splitter. There are two bolt mounting patterns. One recessed around an inset circle and fits standard hydraulic pump brackets perfectly. The other is a square bolt pattern 'on top' of the circle. Those are I believe 5.25" on center, but I can't measure at this point because the pump bracket is mounted. I believe the documentation noted their size. Based on the bracket I am using, I would guess they are a very standard size because mine worked flawlessly...

The second picture for this regulator shows off the bracket shape the best. I would go with that one - it is what matches our inventory. Thanks.

It has a standard external bearing bottom bracket w/shims to fit 68 mm or 73 mm shell widths. The external bearings are also sealed to help keep grime out. I used this to replace an old Octalink bb crankset. I don't believe you can use this for press fit bikes since I don't think they are threaded.

Mr.Olson I lined up the factory stock of my Mini 14 GB model. I had placed a 1 inch rubber stock extension on this stock. I lined up the two stocks and the Hogue that is currently on the rifle lined up with the factory stock including the 1 inch extension. Both stocks gave me the length I needed, I just like the Hogue better. Hope this helps. Dave

These are outboard bearing cups with integrated bearings. There is no adjustment other than installing or not installing spacers depending on whether your BB is 68 or 73mm wide

you are correct the 19b is too big.I contacted my local marine dealer and received the correct information about my boat trailer wheels. there is also a site with a chart on it. http://www.bearingbuddy.com/select.html
