My 76 YM 155D has blown the bearings out of the steering worm gear AGAIN!
I either need to get a new steering column shaft w/gear block or figure out how to rebuild mine properly.

Last winter, I ordered Hoye’s parts, but they were the wrong length/dia, so I tried to straighten the tubes and put it all back correctly, but it let go after only a few hours of use.
Are there any used parts suppliers you folks have dealt with I could get a column or full steering box assy from or possibly a unit from another model/manufacturer that would fit close?
Or do you have any options for getting it rebuilt or new parts manufactured?

Best to ask these explicit questions in the Yanmar vintage section on the site here,


or on the YTOG.
