Default Rockshaft pins
Hello. I was plowing snow with my 149 today, and I heard a "thunk" sound, after which I could no longer lift the plow. After removing the tunnel cover, it appears that the rockshaft is not engaging the lift arm to which the plow lift rod is attached. The lift cylinder is still operating. It looks like there is a pin that goes through the lift arm sleeve and through the rockshaft that might have sheered off. I circled the two spots on the attached diagram that have the pin holes in the rockshaft. The one that may have sheered is the one on the right in the diagram. Anyone else ever experience this happening? Are these pins replacable? It is part #715-3002 in the 149 parts manual. If it is replacable, how is the old portion (broken???) removed and also how is the new pin inserted? Thanks in advance!!

EDIT: Looked at it again, and I guess it could be the lift arm bracket circled in red in second pic. For that matter considering my inexperience..could be some other problem, too, I guess. Any help appreciated

Edit again: Perhaps the lift cylinder went bad? Wouldn't the cylinder leak then if it went bad?? Grasping at straws here!!

My 149 had a broken roll pin a few weeks back exactly where you described...only found out because I tried to lift my snow thrower. Anyway, you'll need to get it out with a roll pin punch (make sure you have the holes lined up before you start beating on it). Roll pins are still available from Cub Cadet. I am going from memory here, but I think it was a 5/16 x 1 1/2" roll pin. Just line up holes and beat it into place with hammer and roll pin punch. should be done in about 5 minutes.

FWIW
If by chance you can't get the coiled pins @ your local Cub dealer, Case/Ih Ag dealers stock them as well as Granger and as always, our sponsors

I wish I had just sheared a roll pin instead of breaking the rock shaft! Good luck with your fix.

Wow, that seems like a very time consuming task. The hardest part of just replacing the coil pin was the access to the rockshaft, such as the angle of the punch, and not enough room to swing the hammer. Replacing the rockshaft itself...I guess you have to remove a bunch of these coil pins to remove the old rockshaft? Hope your fix goes well also.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
