K-45 Drum O-Ring Size

Buckshot · Nov 12, 2024

Can anyone that has a K-45 measure the O-ring for the drum housing for me? I’m out of town all week and need to order some ASAP!!

The OD of the rear housing where the Oring sits is 32mm.

It is a 2MM cross width section Oring.

Thanks, Ronnie, but I’m actually looking for the size of the O-ring. I know it is smaller in diameter than the drum housing

Buckshot,

There is a recess in the drum housing that yes is smaller than the housing itself. I measured that area.

If you order an O-ring that is 32 mm ID x 2mm
Oring width you will have what you need.

Thanks,

Ronnie

Buckshot,

Just got back to the shop and double checked. The O-ring on this motor does stretch quite a bit more than normal to fit the housing.

It is a 2 mm thickness O-ring and the outside diameter static is 27 mm.

Hope this helps.

Thanks,

Ronnie
