Thrust Washer Function

Unlike a standard flat washer primarily used beneath a bolt head or nut, a thrust washer is designed to provide a bearing or wear surface between components experiencing axial forces.

On compatible equipment, 532001370 may help:

• Absorb applicable axial loads
• Maintain component spacing
• Reduce friction between adjacent surfaces
• Limit unwanted side-to-side movement
• Maintain shaft or axle positioning
• Protect surrounding components from direct wear
• Maintain the factory assembly geometry

Its exact installation location depends on the equipment model and assembly in which it is specified.

Thrust Washer vs. Standard Flat Washer

Although the components may look similar, a thrust washer and ordinary hardware washer should not automatically be considered interchangeable.

Thrust Washer

• Provides a bearing or wear surface
• Handles applicable axial loading
• Helps control end play
• Maintains spacing between moving components

Standard Flat Washer

• Commonly distributes fastener clamping force
• Protects a mounting surface
• Typically installs beneath a bolt head or nut

Always use the washer type and part number specified in the OEM parts diagram.

Common Applications

The Husqvarna 532001370 Thrust Washer is used on select equipment assemblies such as:

• Riding mower drive systems
• Lawn tractor assemblies
• Axle assemblies
• Transmission-related assemblies
• Transaxle-related components
• Wheel and shaft assemblies
• Pivoting components
• Rotating equipment assemblies
• OEM applications requiring 532001370

The exact location varies significantly by equipment model, so the illustrated parts diagram should be used to determine its installation point.

Common Reasons for Replacement

Replacement of the 532001370 Thrust Washer may be appropriate if the original washer has:

• Become excessively worn
• Developed grooves
• Become scored
• Bent
• Cracked
• Broken
• Become distorted
• Developed corrosion
• Become excessively thin
• Developed uneven wear
• Been damaged during disassembly
• Been lost during equipment service

A worn thrust washer can increase end play or allow adjacent components to contact each other improperly.

Possible Signs of Thrust Washer Wear

Depending on its installation location, a worn or missing thrust washer may contribute to:

• Excessive axial movement
• Increased component end play
• Abnormal mechanical noise
• Metal-to-metal contact
• Uneven component wear
• Improper spacing
• Shaft or axle movement
• Component misalignment
• Increased friction
• Premature wear of neighboring components

These symptoms can also result from worn bearings, bushings, shafts, spacers, or other hardware.

Related Component Inspection

When replacing the thrust washer, inspect the surrounding:

• Shaft
• Axle
• Bushings
• Bearings
• Spacers
• Retaining rings
• Cotter pins
• Additional washers
• Transmission components
• Wheel hardware
• Pivot components

If the original thrust washer has been severely worn or damaged, inspect the mating surfaces for corresponding wear.

Installation Considerations

Before installing 532001370:

• Identify the exact installation location in the OEM parts diagram.
• Note the original sequence of washers, spacers, bearings, and retainers.
• Clean the shaft or mounting surface.
• Inspect mating components for excessive wear.
• Compare the replacement washer with the original.
• Verify the correct part number.

During reassembly, install the washer in the factory-specified sequence and make sure all applicable retaining hardware is properly secured.

Important Notes

• Verify compatibility with your exact equipment model, product number, serial number, and production revision before ordering.
• Match part number 532001370 directly with your equipment's illustrated parts diagram or OEM documentation.
• The OEM description is commonly listed as “Washer, Thrust 5/8 x 1-10 x 1/32.”
• The alternate formatted part number may appear as 532 00 13-70.
• This component is a thrust washer, not simply a generic flat washer.
• Do not substitute a standard hardware-store washer solely because its approximate diameter appears similar.
• Thrust washers can differ in inside diameter, outside diameter, thickness, material, hardness, surface finish, and intended load characteristics.
• The stated 5/8 x 1-10 x 1/32 dimensions should be treated as the OEM nominal size designation.
• Verify 532001370 rather than relying exclusively on dimensional measurements.
• The exact installation location is model dependent.
• Do not assume this washer is used in the same location on every compatible mower.
• This listing is for one thrust washer unless otherwise specified.
• Do not assume shafts, axles, bearings, bushings, spacers, retaining rings, cotter pins, nuts, bolts, or other hardware are included.
• Inspect mating surfaces whenever replacing a heavily worn thrust washer.
• A damaged shaft or mating component can quickly wear a new washer.
• Check for excessive end play after reassembly.
• Install all washers and spacers in their original sequence.
• Do not omit neighboring spacers or retaining hardware.
• Apply lubrication only when specified for the applicable assembly.
• Make sure retaining rings, clips, cotter pins, or other applicable retainers are fully seated after installation.
• Never modify the inside or outside diameter of the washer to force it onto an incompatible assembly.
• Do not stack substitute washers in an attempt to duplicate the specified thickness unless expressly permitted by the equipment manufacturer.
• Shut off the equipment, engage the parking brake where applicable, remove the ignition key, disconnect the spark plug or battery where appropriate, and wait for all moving components to stop before performing service.
• If servicing a raised mower or tractor, support the equipment securely using appropriate equipment before working underneath it.
• This listing is for one Husqvarna 532001370 5/8 x 1-10 x 1/32 Thrust Washer only unless otherwise specified. Shafts, bearings, bushings, spacers, retainers, and other hardware are sold separately unless explicitly included.
• Match part number 532001370 with your equipment's illustrated parts diagram or OEM documentation before ordering to ensure proper fitment.
