Description

Overview

Meritor Spanner Axle Hub Outer Nut 83mm lets you remove and install common outer hub nuts, so you can service wheel bearings without slipping on the nut faces. Because wheel end work often happens roadside or in tight workshops, this tool gives you a positive 8 point engagement and a drive interface that suits heavy-duty hand tools.

Features

• 8 point profile that grips the outer hub nut faces
• 3.25in (83mm) opening to suit common outer hub nuts
• 3/4in (19mm) drive size to run with a breaker bar or torque wrench
• Designed for wheel bearing and hub service work on heavy axles

Specifications and Materials

Part number: AP4049A.

Also, application coverage includes McGrath Rubery Owen, Standard Forge Rockwell, DANA Eaton Ingersol and Meritor wheel ends.

Key dimensions include 83mm across flats, a 3.25in opening size, a 3/4in (19mm) drive, and an 8 point interface, so you can match the tool to the nut before you start. Meritor Spanner Axle Hub Outer Nut 83mm suits this common outer nut profile on heavy axle wheel ends.

Compatibility and Fitment

This spanner fits outer hub nuts with a 3.25in (83mm) 8 point profile and a 3/4in (19mm) drive interface, so it suits common wheel end service setups. If your hub uses a different nut style or size, choose a different axle nut socket to avoid damage.

Compliance and Safety

Use this tool with the correct rated drive handle, and support the axle safely before you start. Then follow the axle or hub manufacturer’s bearing adjustment and torque procedure, so the wheel end runs cool and stays within spec.

• Wear eye protection and gloves, especially when cleaning threads and washers
• Check the socket fully seats before you apply force
• Replace damaged lock washers, nuts, or threads instead of forcing them
• After reassembly, recheck bearing end play and wheel rotation
