Sir, would you be kind enough to tell me the size of piston for ZB and BB 33 BSA motorcycle.Secondly how many ball bearings are used in the crank case of ZB,BB 33 and 31 engine.What is the exact horse power of 33 and 31 respectively.
Are you aware that BSA had produced BB 31 twin 350 cc? Here they have used BB 31 frame and Triumph 3T motor but this model is not recorded anywhere.Probably only few samples had been made.
I will appreciate for a quick response.
try these guys - they have supplied me with BSA parts a few years ago when I was running a 1942 BSA WM20. My local shop closed down at the beginning of the year. I can't tell you the correct size, am not very familiar with the other engines, but maybe this link will help?

It is likely to be a BSA Meteor or a BSA Airsporter. I am from Birmingham UK and owned one.
Here are a number of links for you which will help identification. I will put the Google link at the very bottom of the post which lists a lot more info. Write back as a COMMENT below my post if you need any further help. I am one of the air weapon experts.

Sources of noise from craftsman oil free compressors (could be Made by Campbell Hausfeld or Porter Cable) include loose fan, failing bearing/s on the piston rod and housing, failing seal ring on piston, air filter intake and loose motor mounts. With the housing cover off, check the fan blade for cracks or loose screw. Turn motor by hand till the piston is at top of stroke. Examine the cylinder for scratches close to top. If scratched, air is leaking past vinyl ring making noise and causing longer fill time. If everything looks ok, suspect noise coming from bearings. Hard to tell if bearings are failing by looking at them. I have seen many failures of the piston bearing on the crank (fairly easy to change, I use alternator bearing from auto parts ) , however, the bearing in the housing just behind the crank bearing is much harder to replacable. Good luck with your fix-it project.
YOU HAVE TO REMOVE UNIT FROM CAR.REMOVE THE CONTROL VALVE ASSEMBLY AND THE ACTUATING LEVER.REMOVE THE PITMAN ARM SHAFT ASSEMBLY.REMOVE THE CAP SCREWS HOLDING THE UPPER END COVER TO THE HOUSING AND REMOVE THE END COVER.USE A SMALL PUNCH OR SCREWDRIVER TO REMOVE THE OIL SEAL FROM THE COVER BE CAREFUL OF THE NEEDLE BEARING.NOTE THAT IDENTIFICATION NUMBER OF THE BEARING IS INSTALLED TO THE OUTSIDE OF THE COVER.PULL THE RACK PISTON BALL NUT AND THE WORM ASSEMBLY FROM THE HOUSING.REMOVE THE PISTON RINGS FROM THE PISTON REMOVE THE BALL NUT RETAINING SCREW. TURN THE RETAINING SCREW HOLE DOWN SO THAT THE BALLS AND THEIR GUIDE DO NOT DROP OUT AND SLIDE THE BALL NUT AND WORM ASSEMBLY OUT OF THE RACK PISTON.REMOVE THE BALL GUIDE FROM THE NUT AND TURN THE HOLES DOWN.THEN TURN THE WORM BACK AND FORTH UNTIL ALL THE BALLS HAVE BEEN CAUGHT ON A CLEAN CLOTH.THERE ARE 23 BALLS.THEY HAVE A DEFINITE SIZE AND MUST BE REPLACED AS A SET.THEIR SIZE IS STAMPED ON THE END OF THE BALL NUT.REMOVE THE BALL NUT AND ADAPTER FROM THE WORM.REMOVE THE RETAINING RING WASHER AND SEAL.FROM THE NUT SIDE OF THE ADAPTER.CHECK OVER THE BALL RETURN GUIDES AND CLIPS THE RACK PISTON THE BALL NUT AND THE WORM.THE WORM AND BALL NUT ARE A MATCHED ASSEMBLY IF ONE IS DAMAGED BOTH MUST BE REPLACED WITH A NEW SET.DO NOT DISTURB THE END PLUG IN THE RACK PISTON UNLESS IT IS LOOSE.IT CAN BE DRIVEN OUT FROM THE INSIDE OF THE RACK PISTON.STAKE THE NEW ONE IN PLACE AT FOUR POINTS.THE END PLUG IN THE HOUSING IS DRIVEN TO THE OUTSIDE BUT IS INSTALLED FROM THE INSIDE.IT SHOULD ALSO BE STAKED AT FOUR POINTS.
If there is not a retaining ring, the ball should just pop out. If there is a
retaining ring, turn it counter-clockwise to remove it. There may be a hole
in the bottom that lets you push the ball out. Inside, there are two things you
need to clean.
Look for three little bearings about the size and shape of a BB. They will
probably be covered with fuzz, so they may look like little felt pads. Carefully
brush away the fuzz. Be careful because if you pop one of those bearings out, it
is next to impossible to get it back in.
There should also be a little black rectangle. This is the window that the
sensor looks at the ball through. Clean it with a damp cloth or Q-Tip. Don't use
any other cleaner since it could fog the window.
