PTO Shaft Bearings..... why so many sizes ?

[Agent Blue]

Finn rock rake, 72" wide. Tore the small bearing from the U joint. I was at my local farm store, Tractor Supply, and ag dealer. No one carried the correct bearing size. Metric, American, we must have went through twenty plus sizes. Either the bearing cap was to big / small or the U joint was too wide / narrow. No numbers on the casting. As Finn no longer makes these machines and I can't find a replacement it looks like a complete new shaft is the answer.
Can't they just make a lite & heavy duty model shaft ? The replacement parts people sure would appreciate it..... me too !

Try NAPA. The other alternatie is tocut the old fork off and weld a new one on with a sizes U-joint that's rated for the power and torque it has to transmit.
