DK40SE Squeal When Moving in Reverse.

[k0ua]

My 2 year old DK40 with 76 hrs on it just started to having the reverse squeal. It is going to the dealer next week for some other HST issues and I hope to have them address the squeal issue as well.

It is a pretty easy fix, the dealer put the kit on mine, no charge.

Yes, due to the excellent work of Coyote Machine's, K0UA's and others' researching and documenting the solution in this thread it is an easy fix. You can easily do it yourself if you prefer to avoid the time and work of sending it to the dealer.

Curious what HST issues you have in addition to the reverse squeal?

When I take my foot off the forward pedal, tractor keeps driving for 3-10 seconds, temperature dependent, lower temps longer drive times. If I try to push on the reverse pedal while tractor is still driving forward... I can't push down on the pedal, or I can push down on the pedal but it seems to not have any effect until tractor stops driving forward. My dealers service manager says he has seen this before on a DK50. He was able to clean some control valve and fix the issue, apparently the entire HST unit needs to come out to get at this control valve. This time Kioti has agreed to just replace the entire HST unit.

Bummer to hear of the problems you've had. I haven't seen any of these issues with my DK40se.

The patch kit fixed it, and likely became a part mod of all tractors made after it.

Well its not an official part of my machine as it came from the factory. I have not had any problems with noise from the machine yet but have taken the time to copy the part numbers down for just in case. Anyway thanks for all the time you guys invested in dealing with the problem and getting us a solution.

Could be wrong but I thought the reverse squeal was a HST only issue..

Has someone shown it to be present on non HST machines?

My DK40SE is a HST not a gear. We have 2 HST tractors and 3 well 2 shuttle and one with what they call a torque converter.

I had the reverse squeal issue with my DK40SE HST also and brought it to the attention of my dealer at the 50 hour service and to my knowledge from following this thread and looking on my tractor they installed the kit to fix my tractor and it worked great for about 50 hours. Then the squeal came back. Has this happened to anyone else? I plan to check with my dealer again tomorrow, but I thought that I would check with you all to see if anyone else had that to happen to them.

Thanks.
