Circle Saver

This system extends component life by keeping the pinion gear lubed without requiring anyone to climb under the machine. The process is faster, safer and cleaner, reducing maintenance downtime.

Front Axle Guards

These skid plates and cylinder guards protect both the front axle and hose routings from external debris, resulting in longer life and decreased wear that drives down maintenance costs and increases availability.

Steering Cylinder Update

These updated steering cylinders offer better sensor protection for longer sensor life, and they also eliminate the need for trim files. This upgrade is compatible with front axle guards.

Engine Compression Brake

This upgrade enhances the machine's braking capability and reduces overheating of the brake pads for longer life, higher uptime and lower total cost of ownership.

Stroke-Limiting Collars

This low-cost collar reduces the chance of drawbar-to-frame contact when lifting the blade, reducing the need to replace or repair the frame and drawbar. The collars are designed to be wear items and can be installed and removed in minutes using only hand tools.

Advanced Control Joysticks

These joysticks allow operators to easily control Cat® GRADE and Cat GRADE with Cross Slope by locating those control buttons on the joysticks themselves. They also allow operators to control auxiliary hydraulic functions. This improves efficiency and increases comfort for more alert, productive operators.

Long-Life Circle-Drawbar Wear Strips

These wear strips help your machine stand up to harsh conditions, and also make for more efficient operation in applications where frequent adjustments to the circle and drawbar aren't possible.

Long-Life Blade Rail Wear Strips

These blade rail wear strips last up to three times as long as standard wear strips, dramatically reducing the time and cost of replacements.

Long-life tip bearings

These tip bearings last up to three times as long as standard wear strips, dramatically reducing the time and cost of replacements.

Greasable Blade Tip Pin Assembly

This pin assembly features a recessed grease zerk and allows you to extend the life of your blade tip bins.

LONG-LIFE LIFT AND CENTER SHIFT CYLINDER INSERTS

These inserts last up to three times as long as standard wear inserts, reducing the time spent on adjusting and replacing them for lower maintenance times and costs.

Moldboard Wear Plates

These wear plates increase the service life of the moldboard — meaning less time and cost for replacements and repairs and more time working.

Capsure ripper tips and shank protectors

These hammerless retention ripper tips offer improved safety and easy installation, for quicker replacements and lower downtime. They also last longer and can be used on any Cat ripper shank with no modifications.

Next-gen filters

We offer a variety of cartridge-style filters. Our hydraulic filters offer excellent flow characterstics with low pressure drop, and our fuel filters provide unsurpassed contamination contorl. Both filters feature a reusable housing, lowering disposal and replacement costs.

Gen 2 Steering Upgrade Kit

A new steering control valve improves performance by reducing fault codes, eliminating external PRV and including an internal pilot bleed warning circuit. Reduced connections mean improved reliability.

Front Frame Doubler Plate

Improved welds on the front frame bottom plate give the frame longer life for lower total cost of ownership.

Fornt Frame Fish Plate Update

This redesigned fish plate is easier to weld, resulting in longer life and lower maintenance costs.

Plate Addition to Drawbar

This plate closes the back of the circle to prevent cracking from center shift contact with the bump pad. That means reduced risk of unscheduled downtime, as well as the maintenance costs and lost production associated with it.

Torsional Coupler Update

A 20-bolt coupler, piston and seals offer longer service life to better align with scheduled transmission rebuilds. They also protect against transmission failure for lower costs and reduced downtime.

Thrust Washer Update

These replacement thrust washers prevent damage to the lip seal and tandem or top hat housing, as well as preventing leaks.

Tie Rod Update

These robust replacemetn tie rods are 15mm wider in outer diameter, offering longer life and reduced risk of front tire misalignment.

Tire Monitoring System

This system monitors tire pressure and temperature to prevent failure and prevent operators from working on hazardous tire conditions. It also helps improve fuel consumption and operator performance for reduced downtime and assists your team in scheduling preventive maintenance.

Driveline Upgrade Kit

This driveline upgrade kit offers an average of 10% lower fuel consumption, as well as lower vibration levels and reduced exhaust temperatures. It also improves engine response at low idle and makes for smoother, quicker shifts while working uphill or under load. For T3 engines, it also increases high altitude derate from 5,000 ft to 9,500 ft.

Mesabi Radiator Upgrade kit

This clog-resistant radiator is more durable and reduces plugging. It's easier to clean, and the ability to replace individual cores reduces overall maintenance time.

Powered Arm Pods

This motorized pod height adjuster replaces the standard manual unit and increases operator comfort by making it faster and easier to adjust arm pod height.

Hydraulic Fluid Monitoring

Real-time hydraulic fluid monitoring helps improve warning levels and simplifies maintenance by logging events and providing accurate diagnostics that help your service personnel stay on top of hydraulic fluid levels.
