OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers SB 45 resto

Ok ill get the pics up tomorrow, I bought a new clutch half anyway, could someone tell me what the bearing number is for the 112 picture in the diagram above I can get most bearings for free at work so i need the bearing number

Item 112 is the Engine Clutch Thrust Race, SB part number 3534016. In Outdoorking's on-line parts store it is part number 020501-160. Unfortunately I don't know the bearing number. Isn't there one stamped or etched on the old bearing in your mower? If not, perhaps another member will know what it is. Of course it is possible that it is a non-standard item, only available as an SB part. At $21.83, it is not all that expensive.

Hi All,
That thrust race does not have any numbers stamped on it and as you thought grumpy, it is specific for Scott Bonnar. You were correct also with the woodruff key, that goes under the clutch cone in the cutter clutch engine shaft.
DJ, what I would have done was to buy a new 5/8" inner clutch half complete with the grub screws, a new PTO engine shaft key to suit; new thrust race bearing, cutter clutch spring and a new clutch cork.
The 3 screws that hold the 2 clutch halves together I purchased are high tensile with nyloc nuts and washers to suit.
Still waiting to see those pics....

ok im having another problem with this mower, every time i stop and start or go around an angle the catcher comes off!!! is there a way to keep the catcher from sliding off the pins???

Hi DJ, if you post some pics of the machine and catcher, I will tell you what the problem is.

Hi to All,
As DJ did not come back with the results, this thread is now complete, and I will now close it. If any member has anything to add, please PM a moderator.

It is a shame when a protracted thread, such as this, comes to an end without a positive result.
