my victa mulchmaster self-propelled is up for a new donk, it has a briggs 850 on it - can someone tell me the shaft diameter & length I need?it's the MSP564 model

Hi Redeye, In order to look up the replacement engine, I need the existing engine's Model, Type, & Code.

The numbers are etched/stamped into the plate above the exhaust.

See the red circle in the picture below:

A great opportunity to put a powertorque on it.

it's a 122Q42-0013-H1



lol, got sick of mixing 2 stroke many years ago

This engine has not been superseded. You should be able to order a new Briggs & Stratton with the same model and type.

The crankshaft part number for that model and type is: 796924

It is worth checking the existing engine's shaft as Victa may have modified it from standard.

See the attached technical drawing below:

Ps. what happened to the existing engine?

its been worked almost to death (l'm a contractor) and not worth my while rebuilding it - thanks for the info, much appreciated...and yes, l need to know if the self-propelled victa boss is 7/8" or 1" internally https://www.outdoorking-forum.com.au/lawn-mo...icta-pulley-engine-4-stroke-vsd-ee14475a

It is most likely 1".

However, Victa may have altered the shaft from the standard 1" size.

Hopefully someone can confirm for you.
