Attex 400 Chief to 23hp Briggs Vanguard conversion

ATTEX Chief Vanguard engine conversion:

Attex 400 chief came in for a complete engine conversion. Our job was to install a new Briggs & Stratton 23hp Vanguard engine, along with all ducting, to provide cool air to the engine. Build a enclosed muffler box to expell hot air upward and out the factory Attex engine cover.

Most of the work centered around building the muffler box to expell all the hot air, as to not melt any plastic body parts.

The exhaust exits through the rear of the machine. Cool air is drawn in through the engine cover too. We were able to retain the factory backup pull starter from the Vanguard engine.

The motor installation in order to have factory engine cover shut, required lowering the engine mount, therefore adding a chain roller to provide chain distance from the mount, This roller mount was built out of 1/2 steel to prevent future problems.

Finished product was real quiet and has tons of low end torque with a burst of around 25mph possible, overall a nice machine.

Only work we did on this machine was the conversion, the owner has already rebuilt the frame, axles and the trans.

So this Attex was brought up be better than new machines.
