Case 450CT

Keep the oil changed in the final drives (my book in my TR320 says every 50 hours). There were durability improvements made I was told from the older CTs to the newer ones concerning the drives. Rexroth builds these finals for everyone practically. They are not perfect. Keep the undercarriage clean (mud caked in and left builds heat which is bad). The S-3s are nice machines. I am sure you will be fine.

Thank you so much for the advice I'm going to change the oil right away what do you recommend (synthetic) maybe the brand even I hope I don't regret this purchase

I think synthetic at the weight recommended in the book would be a good choice. I am curious what the change interval is recommended on the 450. If you have a manual with the machine perhaps you could post what they recommended for the 450-3

CASE builds a quality unit. The 450 CT and wheeled have some of the fastest cycle times in the industry for that size machine. That machine has 285 foot pounds of torque the only machine with more torque is the ASV PT100. The S-3 cab is comfortable and much improved over the 1st series 400 machines. The push power of the 450 is incredible which you will soon find out. The weak point with all CTLs is the drive motors regardless of what color the machine is. Since there is few options nearly all OEMS use Rexroth. I have a friend who is a destructive engineer for a major OEM. He laid out the issues with those drives. The issue is at this point no one is building a better drive motor. So it appears the best solution is changing the fluid often, and keep the drives clean.

Looking for motor/drive also.

People tend to lose track of time or simply don't have much of it to spare for maintenance. But if you change your hydraulic fluid, filters, flush the planetaries and use recommended fluids routinely, these issues can be brought to a minimum.
When buying a used machine, it's always best to change out all fluids, grease all fittings, regardless of what the previous owner/dealer says.
If you are buying a new machine never put faith in a $25p/h shop employee to confirm your machine is up to snuff. Always educate yourself on the maintenance intervals of your piece of equipment and read the book. If you have no book, find one, it will be your best friend when issues arise.

I purchased a 1997 IT14G with 2 speeds,
1. creep-mode 0-6, energizes creep solenoid on drive motor.
2. Creep-lever all-the-way fwd moves over rollover switch de-energizes creep solenoid (mounted on drive motor) allowing 0-12.

Been told Rexroth pump & drive motor.. Hydrostatic
Wanting to road this machine at 22mph per machine specs.

Does anyone know if I need to swap (change-out) theses solenoid-valves on the motor per pics?
Or any other info to go 22mph??
