Keybal,
Welcome to TBN.
I put mine on last night as well.
Mine came to the dealer as K756-97420 at the same price you got it.
I called the dealer the next day and they checked with Kubota. PN K7561-42334 (which is what I ordered for $14.25) is no longer available?!?!? They said there was some defect in the part and they're not selling it anymore. Well, as of now, I don't believe them and think they pulled a switch to get another $10 by including a piece of paper that has the 2 step instructions (take off old one, install new one). I'm hoping the issues I'm having with Kubota are limited to the RTV but I'm not real happy with Kubota right now. I'm not going to even look at them for a new tractor. I'm going with either blue or green.
OK, enough venting. On to the new part.
Pretty easy to install. A pair of snap-ring pliers would speed up the process but I got by with needle-nose pliers. Other tools needed are a 12mm + 13mm wrench and pliers. Had the old off and new on in about 1/2 hour.
It was raining so I only did a short ride.
In low-range. Very nice stopping. It stopped relatively quickly but took the abruptness out.
Medium and high range: It took awhile for it to stop when at full speed in each range. If you don't plan ahead, you may need some brakes.
Although my ride was short, I haven't encountered shifting issues (hard to switch gears) that I've heard about on some of the new ones with this part installed from the factory (thanks Neil). I'll keep an eye on this. There does seem to be some linkages that are adjustable that attach (directly or indirectly) to this part. I may need to do some adjusting. Take a look at the attached pic.
The new part is on the left side. Vertical bar with sleeve for grease zerk and plate on the right.
I noticed the notch on the plate is not centered directlly on the stop. (see gap on top where they meet). The old one sat centered.
I'll ride with it for awhile. Not sure if I'll keep on or revert to the original but will post my findings as I have more time to try it out.
