Hi all,
I am new to this website. I've been following this thread for the last few days because I had the same problem with my Honda HRR2169VLA.
After watching many youtube clips, I cleaned the drive shaft and bushings but my problem is not fixed. I was convinced that it is something else other then the rusted drive shaft or undersized bushing which was mentioned in the technical bulletin #107 per Honda.
What I found on my mower was the V-belt (drive belt if you will) was installed incorrectly. Not sure if it was by the factory or it just jumped of the guide. See the photo:
The belt should not be on top of the metal guide. it should be under. See photo:
.
After I moved it to the other side of the metal guide, it fixed my problem.
While you are working on it, inspect the drive belt, it may be damaged too.
I am not planning to replace the belt. I will see how it runs. I was almost order the bushings and the adjuster arms. But I found this and I stopped the order.
I was able to pull it backward now easily. Should have some friction, but not much compares to before I fix it.
Not sure if your problem is the same, but it worths to check.
Oh, BTW, I also used Lithium grease to lub the bushings.
I am planning to make a youtube video to show the fix.
If anyone need more info or questions, feel free to email me.
