Apparently there was no shame with red loctiting everything in place. The front bearings did not want to come off the shafts. And there was some slop in the rear needle bearings.

Front Bearings NTN 5204 $22ea
Rear Needle Bearings INA 1612B $5ea
Seals TB2 149 100 $ still looking

I assume there is no adjustment for gap and timing. No shims were found.

Nice work bud. How was the coupler/shaft? Any play in the splines?

Good question, didn't even look at the snout or check the play. Maybe I'll head back out to the shop tomorrow and try to disassemble that. I think I left it sitting in the solvent tank, lol.
Any idea on removing and replacing the Teflon strips?

Mild, or anyoune else, have you ever re-Teflon stripped any rotors? The Teflon looks to be in there good. That looks to be this weekend project.
And I found the best deal on bearing kits for our Power Chargers. The bearings are a little more than my ebay quotes.

I have not had to replace them in my 250's or 420s, as they were still pretty good, esp on my 420's. The blowers had very little time on them. I think mike tkach has replaced teflon strips over the years.

i used to do a lot of them,different brands use different stripping so it,s important to get the right material.i had a fixture for holding the rotors,that really helped,i would put the new strips in really hot water to make them pliabel and pull the strip in with some heavy duty pliers.you leave an xtra 3/4 of an inch hanging past the end of the rotor as it will shrink up a little,the next day you cut it off even with the end of the rotor.it should be a fairly easy job being as the rotor only has 2 lobes and they have no twist.forgot to mention,i used atf for a lube to assist pulling the strips in.

Thanks, I'll order the strips when I order the bearings. So, installing the strips is just like installing rub rail. Lol

One thing I just found out is to fill the front with the proper amount of fluid...NOT till it comes out the front plug. I have been doing it wrong all these years. Just figured it out while talking to a tech at The Blower Shop. It is to be filled above the front plug.
