Working on a Cat 973C track loader S/N 3RZ00740. Having one heck of a time getting the track speeds calibrated/synchronized properly. My question has to do with the max track speed calibration in submode 17, the monitor/ecm will not let me lower max track speed below 10.9 kph. Book says to lower it to around 9kph. Everytime i try lowering it I get the not accepted symbol. I can get the rest of the settings fairly close so the machine runs/tracks/operates pretty decent in "turtle" mode, but it is still kinda herky jerky when steering/ changing direction. I've also noticed that trans pilot pressure is about 70psi higher on the right side vs left (according to ET). Can't find any info on adjusting these pressures in the service manual. I've had success calibrating other machines in the past but it's been afew years since I've fooled with one. Reason for needing calibrated is pumps and motors were sent out for re-sealing (3 of the 4 were leaking) Any suggestions or advice would be greatly appreciated... Thanks for taking the time to read my post..hope it makes sense as i dont type to well or post much but have gotten a wealth of knowledge from the forum. Many Thanks
