Hi All,
I’m troubleshooting a problem with my project Honda HRX217HZAA lawn mower’s hydrostatic transmission. After completing the engine rebuild and getting it running, I tested all systems: blade clutch and transmission.
The blade clutch works well, but when I engage the self propel the mower barely moves itself forward. I changed the hydrostatic transmission fluid last night and reassembled the mower. Today I try using it to mow the lawn, the same problem exists. Also there is some resistance when I push the mower forward; to me it seems slightly more effort is required to move the mower forward when compared to my other HRX217HYAA.
I used genuine Honda hydrostatic transmission fluid and turned the input shaft counterclockwise with the drive engaged, the axle spun close to the same RPM as the input shaft. I tested spinning the input shaft clockwise, but nothing happened which may be by design. The drive is still engaged at this point. I think I got all the air out. Let’s reassemble then test.
My questions are:
1. Could overfilling the transmission cause this problem? There wasn’t instructions I could find online to follow that I could find after doing a quick internet search to perform the maintenance.
2. Could the transmission need a full rebuild?
3. Did I not get all the air out of the transmission?
Appreciate any help and suggestions!!
Thank you,
