933C HystatNon-Current
933C - 1999, NACD, LACD, APD
Overview
The 933C has a single lever joystick control for speed, direction and steering. Full powerturn capability is made possible by maintaining power to both tracks at any ground speed or turning radius. Operating a loader of this size has never been easier.

Overview
Outmaneuver every job you tackle
A single lever joystick control is all that is needed to control speed, direction and steering on Cat 933C Hystat Track-type Loaders.
Power Train
Hystat Power Train System
Quick response and acceleration plus better maneuverability decrease cycle times and increase produce.
Caterpillar 3046 Diesel Engine
Smooth, responsive power, excellent fuel economy and lasting reliability.
Track Motors
The high pressure motors are 2-speed type (turtle/rabbit). The Hystat motors convert hydraulic power to mechanical power.
Hydraulic Lines
Hydraulic Lines XT-6 hose is used to connect pumps and motors. O-ring face seals ensure tight and reliable connections throughout the Hystat system.
Power Train Oil
One filter is located in the charge pump outlet from each of the hystat pumps. This location assures that all oil is filtered before entering the piston rotating group portion of the hystat circuit.
Parking Brakes
The parking brakes are a multi-disc design. These parking brakes are spring applied and hydraulically released.
Final Drives
The Hystat final drive is a double-reduction unit, similar in design to that of the current hydrostatic track loaders.
Cooling System
The cooling package is a stacked configuration, with the configuration of fan - oil cooler - radiator. The blower fan forces cooling air first through the oil cooler then through the radiator.
Drive Pumps
The pumps are over-center style, providing forward and reverse directions by changing the direction of flow from the pumps, and are controlled by a hydraulic pilot control system (joystick).
Hystat Control
Joystick Control
The joystick control is simple and easy to understand. The joystick is ergonomically designed to fit comfortably in the palm of your hand.
Direction/speed
Machine direction and speed are easy to handle with the four easy movements on the joystick.
Steering
With the machine moving in forward or reverse, moving the joystick to the right results in the machine turning to the right; moving the joystick to the left causes the machine to move to the left.
Operator Station
Ease of Operation
All major machine work functions can be accomplished with just two hands.
Reduced Operator Fatigue
Low control lever efforts help increase operator productivity each day. Day after day.
Tinted windows
A continuous, three- piece glass windshield and a large, single-piece door glass provide excellent visibility to the work site.
Control Console
Control console is back-lighted and contains controls for cab temperature, fan speed, the front/rear window washers, and two-speed wipers. A cigarette lighter and ashtray are also included.
Contour Seats
Ergonomically shaped seat cushions comfortably support the lower back and thighs, while allowing unrestricted arm and leg movement.
Center Brake Pedal
The center brake pedal is located towards the floor of the operator's compartment (cab and OROPS) and can be used to stop the machine by pressing the pedal all the way down.
Footrests
Since Hystat track loaders are not steered with foot pedals, two footrests, one on each side of the center brake pedal, are provided for enhanced operator comfort. Footrests are also adjustable.
Joystick
The joystick is used by the operator to control the speed, direction, and steering of the machine.
Bucket Control
A single lever control handle is used to control the bucket. The control lever operates on two axis: fore/aft for bucket lift, side to side for bucket tilt.
Updated Dash Panel
All gauges are backlighted for clear viewing when lighting conditions are poor.
Bucket and Lift Arms
Buckets
There are 2 durable, high quality buckets available for the 933C.
Arms
Solid-plate lift arms provide strength and durability for excellent lift and breakout capacities.
Hydraulics
Hydraulic System
State of the art hydraulics. 17 percent increased pump flow provides faster cycle times, resulting in more work done per hour.
Undercarriage
Updated Rear Track Guiding Guards
The new guarding prevents material ingestion into the sprocket and rear roller area. The result is the introduction of bolt-on rear guiding guards which enhance rear guiding due to increased length over current rear guiding guards.
Track Roller Frame Update
The track roller frame provides the mounting points for all major undercarriage groups and determines the different configurations within the individual models (Standard or LGP).
Updated Recoil Guards
The recoil guards protect the recoil mechanism from impact damage and reduce the amount of abrasives entering critical wear areas.
Double Flange Bottom Rollers
The double flange bottom roller group serves the same function as the single flange group, but it is designed with an additional outboard flange to increase its guiding ability.
Track
The track group serves to transfer power from the final drive to the ground through the use of links, bushings, pins, and shoes.
Optional Full Length Track Roller Guards
In order to increase the protection of the roller wear surfaces from abrasives and rocks, full length track roller guards are offered as an attachment for all undercarriage configurations.
Serviceability
New Engine Enclosure Panel
The 933C loaders are built with an updated enclosure panel which incorporates a built-in grip handle for easy removal and access to the vertically mounted, spin-on engine and oil fuel filters, SOS valve, and fuel priming pump.
Filters & Change Intervals
The combined power train and implement hydraulic system uses two 7 micron spin-on type filters located inside the rear access door for easy accessibility.
Fluid Check Points
The engine oil dipstick, engine oil fill cap, and radiator cap are located inside the access door on top of the hood.
Fluid Drain Locations
The engine crankcase drain plug and the radiator drain valve are accessible underneath the machine by removing the access covers from the bottom guards.
Grease Points
The loader lift, tilt cylinders contain grease zerks on both ends of the cylinder pivot pins.
