Help request from England O&K RL1C

Hi, we are restoring an O&K RL1C at Leighton Buzzard, and the parts described as Mitmerkmehrlotz are missing - item 15040 on the parts diagram. They are the couplings between the flywheel and the gearbox.

Can anyone help with a picture or a specification for these?

Many thanks,

Simon Lomax

Hello Simon,

originally, these are of flat steel plated on both sides with leather or rubber. As you say, they transmit the torque between the engine and the gearbox and should absorb shocks.
Nowadays, it is possible to replace then by rubber blocks with a textile inlay.
