Replace motor on MTD 5hp chipper shredder—shaft?

[Modrob]

Odd, but I’ve replaced carbs on a couple of lawn mowers, small tractor, and chainsaw with cheapies and so far so good. But yes, I believe it would be better with OEM parts. But EXPENSIVE. When I can, I’ll get the good stuff. For example, I’m having to do a lot of top end work on a finicky Kohler 25hp, so I’ve been using OEM on it—sure don’t want to have to tear it down again as it’s on an articulated tractor with hydraulics…
So…for the small stuff, the Chinese units get me by…

Modrob, I am not sure if you still need information on engines with MTD tapered shaft. Assuming you might, briggs no longer makes the engine with the tapered shaft. MTD and Troy-Bilt now have a relationship with a Chinese manufacturer for their engines. I found on ebay a Zongshen Engine 6hp 208cc with an MTD tapered shaft. If you search ebay for this, it will pop up for $135.45 free delivery from Small Engine Warehouse. In looking at the photos, it looks like a standard MTD taper 7/8" to 1" inch. There is a contact seller link. I would think they could give you the complete dimensions on the crankshaft and mounting bolts. In looking at the engine, the form factor matches what is on my Troy-Bilt chipper shredder. While it might not be the best quality (who knows), at $135 it is not a big risk. I am thinking of buying one and keeping it as a spare. It only takes 1 rock in the chipper to shear the crankshaft. Hope this might be helpful

I think that this is a AI bot post. I could be wrong.
