Kubota b-7800
I have B-7800 that has play in the forward/reverse pedal. What I found was a worn bushing mounted lever mounted way inside on the transmission I think this looks like a problem. What it does is make the forward/reverse pedal have travel in the neutral position. The year is a 1993 HST B-7800. I have parts manuel and a owners manuel so I am trying to find what I need. Any help would be apprieated. I am thinking #20

It looks like 20 is the larger overall bracket. 40 looks like the bushing. What is 50.. dust cover?

You may just need the bushing #40, if nothing else is wore out. Best thing to do, would be to take it apart, inspect and measure.

The #50 is the shaft where the bracket #10 pivots with the bushing #40.

You could be right with a borescope it look like 20, and you be right. There is a upgrade from the orginal which I think is the bearing. I think the only way is to open it up and inspect it. Thank you for the advice.

Your right It is a 1993 and the neutral holder are the bushing failed. I am hoping the rolller which is a upgrade will fix it. Have you change one before the shop manel does not show a procedure to change.

Will my 2003 Kubota B7800 should be repair tomorrow as soon as the bearing gets here from Messicks. It was not the most fun job. Getting the race off was the hardess part. Also looking for my gray Kubota paint was my next job. Here are some pictures.
