BX 2660 possible cracked case at PTO bearing housing

[marktm]

Hearing protection!! Did not hear the clanking of the PTO U-joint hitting the surrounding metal - including an upside down installation of a bolt for Pat's swing arm system (replaced with yellow bolt correctly)

A small leak is evident around the bottom third of the PTO bearing housing. Can this be fixed externally?

Looks to me like your leak originates about 2 or 3 o-clock and runs down to the bottom. You need to clean it up good and see for sure where the leak is. It's going to be a challenge to get it clean enough for an external repair but certainly worth a try.

I agree. Original thought was the seal, but after several "cleanings" there was no evidence of any fluid in the seal chamber - then noticed the "sheen" was around the housing. Considering the damage from the U-joint, it's likely the bearing itself cracked it's own housing.

The best I can do is lower the fluid level well below the seal/housing, solvent clean the entire area several times, letting any fluid reappear that remains then lightly sand the outer housing crevice area only, then use either liquid nails or epoxy to form a bead from 12:00 the 12:45. Let it set and spray paint the repair area to match. Note that the PTO shaft is not "loose" at all - feels rock solid.

The real issue is how did the U-joint ever hit these areas?? Got to figure that out. I've been using the shredder for 10 years. Something recent has changed.

I would use JB Weld, and you want to roughen up the surface so it has a surface it can grab. I see no crack but there is a suspect pin hole in the casting that might be the source. Check your u-joint at the coupler and the coupler itself.
