Need a part number - Please Help!
 

Hi All,

I'm looking for help sourcing at least a part number for my MR4-BC slipper conversion.

Can anyone advise the part number for the replacement spur gear for this option part? can't find it anywhere on the web :( it basically looks like a B4 spur, but has a larger hole in the centre. (NO! I can't just drill out a B4 spur, would be off centre with my drilling skills...)

Thanks in advance

How much bigger is the centre hole? Maybe the B-Max4 spur gears fit.

10mm bore on the MR4/MX4, Bmax is 12mm, and the Schumacher Catsex is 8mm... looks like I'm stuck, will have to get my drilling skills improved!

In this case, I'd use a small piece of 12x10 mm brass tubing as an adaptor for the B-Max4 spur gears, should be the most precise solution. ;)
