[DG11] M81137 rotary drive unit
I'm interested in adapting a M81137 rotary drive unit to replace my original Neco 17Dr8 drive unit. Can anyone tell me the shaft diameter and length on the Raymarine DU? I was hoping to use the same chain and sprocket off of the Neco unit.
Thanks

Hi johnspeetjens

Thankyou for your enquiry.

We have attached a pdf of the generic sprocket shaft and keyway details, please note this is for a standard 3/8" pith sprocket, whilst the sprocket details will change, the shaft dimensions remain unchanged.

You will need to check the correct reduction ratio is applied since the NECO drive will have a slower output shaft speed than the Raymarine drive.

Regards

Derek
