4300 Range Shifter Broken

[paulcapasso]

Hello Everyone!
So I have done some research on this forum and found that the 4300 series has a issue with snapping the range selector shaft on the side of the case. In result you need to take off the rockshaft assembly to access the pin ot remove and reinstall the new range shaft. Deere wants $86.00 hour labor and said it's a 12-14 hr job. I'm 3.5 hours into it and waiting on the new shaft from Deere to install. I'm thinking maybe 4.5 hours more with paint to dress it a bit better and no loss of fluid to complete. Who else has this problem and how was the experience. I have pics I need to upload for everyone to see. This is not as bad as the dealership said it was going to be.

I've not had this problem yet. Sounds like you're coming along ok,good luck with finishing up. Keep us posted.

IIRC it was a issue if where the original shaft had a o ring groove cut in the shaft made it weak. Correct?

Something like that...this is one of those problems that can be prevented (or at least lowering the probability) by lubrication. On my sync-reverser transmission, the shift lever is used frequently, the range selector not so frequently. I would imagine most HST owners leave their range selector in B range.
I use Fluid Film...will that guarantee no breakage...nope, but it lessens the possibility.

BTW, I started lubricating both the shift and range levers after reading that original thread.

Roy,
I replied to a 2010 post that you were involved in with a very muddy rental 4300 that looked like it was really neglected. Well the parts will be here tomorrow and hope to get it together by tomorrow afternoon and use it tomorrow night. I use the range select a lot with mine. It's a HST and I go all around my 2.5 acres of property moving trees and other BS. Low gear for digging and scraping or hauling large logs, Med gear for moving across the property and High if I'm going to the neighbors properties that is frequent. I'm again not that far in to the disassembly and should go back together rather quick.

Paul, would you mind posting a picture of the left hand parking brake linkage where it goes into the case? I'm pretty sure mine is dragging sometimes, and heard the retract springs get weak, plus it needs lubed periodically. Looks like you have it fully exposed.

Brent, I'm trying to figure out the picture uploads at the minute, The parts will be in tomorrow, I plan to have it mostly together for tomorrow night. When I reinstall the parking brake I will get the pic up here for you. It's currently removed off tractor.

Look at the Syncro set on right. Does that look broken to you?
