1450 PTO clutch smoking
 

Hello all
I finally got my 1450 mostly back together, but having problems with the magnetic coil rubbing the back of the pulley hub. I added some shims behind the pulley hub, and a washer under the springs to put additional pressure on the coil backing plate.

any ideas?

Did it have shims and washers prior? You may have the rotor to close to the winding field...What gap do you have for the clutch and rotor? Run it too long like that and you will short it out.

There were no shims (on the crankshaft) behind the pulley hub.

question, does the plate holding the coil plate bolt directly to the block?
That makes sense to me except the holes in the sheetmetal are wallowed out from moving around which suggest that it floated on the studs.

Go to Partstree it will show you all that is needed to reinstall back to OEM..The ones I have taken off bolted directly to the block...HTH

The diagram doesnt really show.
I agree bolted to the block makes sense.
I tried it that way but the back side of the plate didn't sit flush across the block and where the plate hit the crankshaft seal, maybe I don't have the seal seated all the way.

Most of those on the Kohlers have 4 small tabs on the plate with the coil that fit into the bore that the crank seal fits into to center it. If your seal is not in deep enough that could be your problem.

welp, it lives!
I set the crank oil seal deeper, ground off the deformed metal from where the backing plate had walked around, centerfed it, bolted it tight. I will be looking for a replacement coil eventually.

Made about 2 trips around and stopped again, did a little troubleshooting and found the wire harness had slipped off the rectifier.

Overall it ran very well, still have to tweak the governor, because it wasn't running at full rpms.


thanks for the input.
