Onan P224 Starter Motor Tabs

Hi,

 

My father in law has an old Toro Wheelhorse zero turn with the Onan P224. Its been a great machine but unfortunately the starter motor stopped engaging correctly and after ripping it out we found the bolt mounts that are cast to the cylinder are cracked and allowing the starter to come away once loaded up during starting. Has anyone here had good success tig welding these? If not it looks like I can fit a sump and starter from a B 43E, B 43G, or B 48G but I haven't seen this done with the bigger P224. Every site I look at lists the smaller P220 or 218. The sump gasket is the same part for the P218, 220 and 224 so I'm hopeful but can anyone confirm the B 43E, B 43G, or B 48G sump and starter can be used for a P224?

 

Thanks,

Patrick

I see no reason why welding it would not work. Allow some input from some others though.

I would guess welding would depend on how it's cracked. Got a pic?

Aluminum casting and near a precisely machined cylinder? 

I’d be looking for someone having deep, demonstrated precision equipment welding experience managing thermal stresses and material transformations in aluminum.

Thanks Guys. I haven't got the motor with at my place so I'll try grab some snaps when I see it next. Its very much cracked but I'm hoping to get away with welding. Would love to know of someone throwing a B series pan on one as it looks like a good fit comparing to pics online. 

 

Cheers,

Patrick

The P engines crack there alot...my P220 was repaired by mig welding.  I pulled the engine, thoroughly degreased it, took it to my buddys house, i had modified some old cheap welders vice clamps to hold the split sections closed.  He wire wheeled the damage; welded about 3/8", ground it down, wire wheeled..welded another 3/8", etc etc..until both were welded up.  I ran a bit down the holes as one was partly closed from welding.  This was an opportunity to offset the hole slightly closer to the flywheel.  I put on a new starter and used cheap feeler gauges to shim it until i liked the mesh pattern.  Bad mesh is what usually causes it.

Thanks Red, this is great info and good pics. My Father in laws looks very similar to yours. Inner tab is cracked right through opposite the cylinder and has a smaller one like yours at about 4 o clock if that makes sense. The motors out so I'll pull the flywheel and what not and see if I can find someone to weld it then report back.

If you do, stress penetration over building it up, the starter body sits nearly flush with the length of the mounts so if it gets built up you will have to grind it down.
