i always have this dilemma when repairing this cb15 bowl bearings? do I recommend the customer purchasing the hole assembly with the bearings and seal already in place for around 500$ or is repairing it, installing new bearings and seals.
But the problem is i always have issues getting out the cracked bearings because this thing is so small, so it turnes out customer is paying so much more in labor.
Sometimes I get those bearings out in one piece then customer lucks out and pays Much less.
It all comes down to if you have a arbor press and a fixture to hold the shaft for proper removal and replacement of the nut. It’s still $275 for parts, and about 40 min. labor. But the real problem is if the customer/user knows not to immerse the blade assembly. Or leave liquid in the container for extended periods. After all, there is no seal other than the bearing seals, a “V” ring and a labyrinth. Now if there product ph is far off 7, the bearing housing will corrode. That would be a good reason to replace as a cartridge. Also if they have been immersing in a strong cleaning solution Any shaft damage or wear would also indicate cartridge.
I want to caution you that the 2 washers, nut, blade, bearing cap, Bearing inner races, bearing spacer, and shaft shoulder have to be clean and benefit if a thin film of anaerobic sealant is placed on them to prevent wicking of liquid along the shaft.
