Detailed Description

The 3B1472 LOCK CATERPILLAR is a flat, dual-hole mechanical lock plate used to provide positive secondary retention to bolted connections in Caterpillar machinery. Designed to be used in tandem with bolts and nuts, this locking plate holds fasteners in place under conditions where movement, vibration, or torque cycling could otherwise lead to loosening or failure.

Unlike spring washers or thread-locking compounds that can degrade over time, this lock plate offers a mechanical advantage by physically restraining fastener movement. It can be used to connect adjacent bolts or serve as a tab that bends against a surface or nut face, effectively ‘locking’ the bolt into place.

Constructed from high-tensile carbon steel, the 3B1472 LOCK CATERPILLAR is durable enough to withstand bending during installation and strong enough to maintain locking force over the lifespan of the joint. Each plate is precision-cut for an exact fit and designed to be used in high-impact zones where structural integrity is paramount.

Compatible CATERPILLAR Models

The 3B1472 LOCK CATERPILLAR is used across a variety of Caterpillar machinery, particularly in bolted joints that require long-term integrity. It is commonly installed in structural, frame, or pivot assemblies where rotational forces or vibrations might compromise standard bolting systems.

Typical compatible Caterpillar models include:

• CAT D6R Dozer

• CAT D7G Bulldozer

• CAT 966H Wheel Loader

• CAT 930K Loader

• CAT 320D Excavator

• CAT 325C Excavator

• CAT 980G Loader

• CAT 345D Hydraulic Excavator

• CAT D5K2 Track-Type Tractor

• CAT 777F Off-Highway Truck

Lock plates like the 3B1472 are often located on fasteners securing equalizer bars, track frames, undercarriage joints, and engine mounts. By maintaining bolt alignment and preventing loss of torque, this component ensures long-term safety, efficiency, and machine longevity.

How Lock Plates Improve Equipment Integrity

In heavy machinery, bolted joints are constantly exposed to forces that loosen or stretch hardware over time. Vibration, torque cycling, temperature fluctuations, and operational shocks all contribute to fastener movement, which can ultimately lead to:

• Reduced structural stiffness

• Increased wear on joint components

• Risk of catastrophic failure

The 3B1472 LOCK CATERPILLAR helps mitigate these risks by holding fasteners in place — even when other methods fail. Its dual-hole tab design ensures it can either bridge multiple bolts or be bent against a bolt head or nut for mechanical interference.

It’s simple, effective, and durable — a small investment with a big impact on machine uptime and safety.

Maintenance and Replacement Guidelines

While extremely durable, the 3B1472 LOCK CATERPILLAR should be inspected and potentially replaced during any major bolt retorque, frame overhaul, or disassembly. Here’s what to check for:

• Metal Fatigue or Cracks – Replace immediately if bending weakens the plate’s integrity

• Rust or Corrosion – Surface rust is normal, but deep pitting can weaken the part

• Loss of Tension – If the locking mechanism no longer contacts the nut or bolt head

• Deformation Beyond Use – Severely bent or twisted lock plates should be replaced

Installation is straightforward: simply place the lock plate over the bolt(s), torque the hardware to specification, and bend one tab securely against the fastener.
