q&p Spindle Assemblies 3-Pack for LA100-LA165 Tractors - Complete Hub with Bearings & Grease Fitting

These replacement spindles restore mower deck performance by supplying a complete spindle hub with bearings, grease fitting, and mounting hardware. Sold as a three-pack, each unit is engineered to match the critical dimensions and thread types used on many compact and mid-size garden tractors so you can replace worn or damaged spindles quickly without hunting down multiple components.

Will these spindles fit my tractor model?

They are engineered for a wide range of models commonly labeled LA100 through LA165 (Garden Tractor/GT) where the listed OEM numbers correspond. Check your original spindle part number or measure the mounting and thread specifications before ordering.

• Replaces GY20454, GY20867, GY20962, GY21098 and AUC15811 equivalents
• Intended for LA100, LA105, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, LA155, LA165
• Verify spindle height and thread size against your original part

How do these spindles install and what hardware is included?

Each spindle ships ready for installation with the most common fasteners and fittings. The assemblies include mounting screw holes, washers, nuts for both ends, and a grease fitting so you can bolt them into place and lubricate them immediately.

• Package contains three complete spindle assemblies
• Each spindle includes four pre-drilled mounting holes
• Comes with washers, nuts for both ends, and grease fitting installed

What are the critical dimensions and thread specifications?

Dimension compatibility is crucial for safe deck rotation and belt alignment. These spindles have a measured height and thread configuration designed to match many OEM units so belts and blades maintain proper clearance.

• Overall height approximately 7 1/9 inches (approx. 7.11")
• Thread types matched to common OEM: 9/16"-18 UNF and 5/8"-18 UNF where applicable
• Bearing- and grease-ready design for straightforward maintenance

What maintenance should I expect after installation?

Routine lubrication and periodic hardware checks keep spindles running smoothly and extend blade alignment life. Grease fittings allow fast re-lubrication, and inspecting mounting fasteners after a few hours of operation prevents loosening from vibration.

• Grease through the fitting after initial installation and every season
• Retorque mounting bolts after first use and check periodically
• Replace if excessive play, noise, or visible damage appears
