My plastic wheel gear teeth were wearing on my lawn boy. Before replacing any parts I first tried to diagnose why it was happening. This is what I discovered. Worked perfect and years later is still working. Hope this helps. https://studio.youtube.com/video/RVK_po7BRZs/edit
Look at this video and see if it is your problem. My wheel gears were wearing off on the outer edge because the wheel mounting plate was not parallel. I corrected the toe-in condition with an inexpensive solution. If wheel gear is plastic then the wheel teeth were wearing, but if you have a...
Check to see if there is any wear in the wheel gears. I have a lawn boy that is about 15 years old. About 10 years ago I heard a grinding noise coming from the wheel gear area. I removed the dust cover and re-installed the wheel. When turning the wheel by hand I observed that only the outside...
Grinding can be caused by misalignment of pinion and wheel gear. Had Lawn Boy with wheel gear wear. Pivot arm (wheel mounting plate toed-in as the result of height adjust arm pressure) was not parallel with the mower body. Corrected by installing a simple "nut stop" to the rear of the wheel...
The height adjust arm is causing the pinion not to mesh correctly with the wheel gear. It causes the wheel mounting plate to toe-in to the front. I bet your wheel gear is steel. Originally the wheel gear was plastic. In that case the wheel gear teeth wore out on the edge. When people started...
A question. If you remove the wheel, does it have a dust cover? If so remove that cover and reinstall the wheel and see if the gear and pinion mesh correctly. You can raise the front of the mower and rest it on something so you can move the wheel by hand. If the pinion and wheel gear are only...
Did you click on the link and see the photos? If you remove the "dust cover", reinstall the wheel and lift up the back of the mower and set in on something and view the pinion/gear meshing and just see the tip of the pinion contacting the gear on the outside edge, then that is probably what is...
When you say left side pinion gears do you mean the gear inside the wheel or the pinion on the end of the axle. I have an older model in which the metal pinion did not mesh correctly with nylon gear mounted inside the dust cover of the wheel? I have attached a link to show how I made mine mesh...
This is how I fixed mine years ago and it still works. The wheel height adjuster is putting too much horizontal pressure on the wheel mounting plates causing a toe-in condition. Read comment with each photo Hope this helps...
Yes I agree that the front of the deck should be lower. All I had to do it loosen the nuts holding the J-bolt to move it down slightly from level. Thanks for the reply.
Can you remove the dust cover over the inside of the wheel? If so then remove it and then reinstall the wheel. Set the back of the mower up on a jack stand or block of wood and turn the wheel by hand and see if the wheel gear is meshing correctly with the gear that is on the shaft. If it looks...
Since mower was given to me this is how I did it. Also fixed steering link. See comments with each photo. https://www.flickr.com/photos/24045457@N02/albums/72157719169006174
