I Recently purchased a 1996 750C (serial # T0750CX815491) with 4,136 hrs. Was told it had series 2 updates but I’m unaware exactly what the series 2 updates are. Could someone fill me in? Also I’m getting a F629 code and it’s doing some miss tracking. Was told this could just need re-calibrated. Any insight on that issue as well? Thanks in advance!
Welcome to HEF Troy ! Thanks for posting the serial number. To answer you question on the difference between 1 and 2, mostly cosmetic like park lock lever placement, grips on the levers, etc and software changes. Engines are different as well I believe. Your code is for the left motor speed sensor. Yes you could try a calibration. That is the first thing I usually do. If you don't have it you will need the Operation and Test manual TM1588 for the procedure.
Thanks for the reply mg2361. Yes, I have a stack of books that came with it when it was delivered. I will look through and find the calibration procedure. I guess my biggest question at the moment would be, what would it cost to do the series 2 updates? Mainly would like to have the ground travel speed buttons on the FNR handle instead of having a lever to the left of the handle that you slide back and forth to adjust your ground speed. I have a 2000 650H dozer and I love the way the controls are for the travel and the blade. I’m completely fine with doing the work myself as I’m a mechanic, I just don’t know if it’s possible to switch it over to a handle with the speed settings on it. Thanks!!
Are there any 750C series 2 owners on here? If so would you mind to take some pictures of the inside of your cab of the controls and gauges so I can compare them to my 750C? I’m trying to get everything in order to convert over to the series 2 controls. Thanks all, and any input at all on doing this conversion would be appreciated more than you know. I started my own excavation business 2 years ago and I’m growing and expanding my fleet. Trying to keep my machines simple and easy to operate for maximum efficiency!!
Unfortunately it can't be done. Deere offers no kit/instruction or even a detailed description of the differences.
Hmmm, well I can be stubborn sometimes and since you say it can’t be done it challenges me.. lol.. I’m going to tear into it and see what I can find out. I know my series 1 750C has what appears to be a potentiometer that adjust the speed settings as you slide a handle back and forth. I’m going to take my 650H apart and see how the handle functions on it and see if I can make something work. I’m sure a guy could probably eventually make something work. Thanks for your input!
