Sorry if this already discussed, its my first time posting and I couldn't see anything about this specifically. I saw that this is an issue that a lot of 1023/1025/1026 have had issues with the rockshaft snap ring coming off. I was plowing snow with my 1023e, which has 25 hours on it, and the entire rockarm came off. Unfortunately I only use this tractor for snow removal and occasional yard work, so it is currently over 2 years old and not under warranty. Also the nearest Deere dealership is 84 miles away. I am going to try to deepen the groove for the retaining Snap ring and replace it with one from fastenal. I called the dealership and they were of no help, even after I sent the repair paper that another poster had taken a photo of. My issue is that the L snap ring was not in the groove, and when I set it in the groove, and moved the rockshaft and rockarm snug with the housing on the L side there is play between the arm and the ring groove on the R side. I just wanter to make sure that that is normal, or if I should shim it with washers or something. IMG_2467.JPG

This is with the arm on, that gap between the arm and groove is the concern.

This the on the R side, which is more snug.

Thanks for your help.

Interesting topic ... After reading it, I couldn't help but wonder what my rock-shaft and snap rings looked like, with 28 hours on the tractor
As I looked at the left side rock-shaft splined end, I immediately saw there was NO snap ring, nor a grove for one.
What I did see was the mower lift bracket attached to the rock-shaft lift arm. Under closer inspection, I see the snap ring sandwiched between the rock-shaft lift arm, and the mower lift bracket.
This must have been done at the dealership when the mower deck was installed when the tractor was new in 2013
I'm thinking with the mower lift arm holding the snap ring in the proper position, there won't be a problem with losing the snap ring and the shaft sliding in.

BTW ... The snap ring on the right side rock-shaft is in the grove where it belongs ... no problem there.

Perhaps this a possible remedy for others to consider ... :dunno:
