Added a support bearing

37chief · Jan 30, 2017

I don't know why the mower company didn't put a support bearing near the gear box. I was getting some serious vibration on my mower. I thought it was because of missing lades, which will also will cause a vibration. I found out the universal joint near the gear box was going bad. With the belts pulling on the pulley it was causing the U joint to take more strain than it could.I installed a support bearing and so far it is working ok. I have seen some mowers with a sleeve, instead of a U joint,but every thing needs to be perfectly level. Even then with the flexing of the frame it would still put strain on the gear box bearing.

Good Idea. Well done. Some engineering is done on sight. All products are prototypes. Jim

That pillow block should take all of the whip out of the shaft. nothing like a little on site engineering. Many years ago me and my dad did something like that on the field chopper with a couple of wood blocks and a chunk of Teflon plastic. even threaded in a grease fitting.

Hello 37chief,

Excellent solution, should last a very long time,

Guido.

I like the repair, you did a nice job. However if the framed does flex it will still load the U joint if the joint is tight. Two U joints or a Lovejoy type coupling wotj a soft spider would take care of that. Does the frame flex though? It looks pretty rugged.
