John Deere Plain Circular Shim - R49004

Overview

John Deere Plain Circular Shim, part number R49004, is a thin, circular shim designed to fine-tune spacing and tolerances in mechanical assemblies. It is intended for use in John Deere equipment and related applications where precise, small-thickness shims are required. The shims in this line accommodate maximum thicknesses up to 0.77 mm. Solid shims without holes in this family are coded 2662-12.

In practical terms, these shims help achieve proper alignment, reduce gear misalignment, and maintain correct seating of mating components, contributing to consistent performance and reduced wear in service or maintenance scenarios. The R49004 variant provides a standardized, drop-in solution for applications needing a tight, circular fit.

Key dimensional references (typical for R49004 in the Deere ecosystem) include an inside diameter around 64.50 mm, an outside diameter around 76.00 mm, and a thickness near 0.249 mm, with material and fabrication consistent with steel shims used in agricultural and industrial equipment.

Key Features

• Part Number: R49004
• Type of machine suitable for: John Deere equipment and related mechanical assemblies that require a thin circular shim for precise spacing and alignment (thickness limits to 0.77 mm).
• Installation tips: verify mating surface cleanliness; ensure correct orientation and seating; confirm total stack height when multiple shims are used; handle with care to avoid edge burrs; reference the documented inner/outer diameters to ensure proper fit.

Note: The R49004 shim is part of Deere’s plain circular shim family and corresponds to a solid, hole-less variant documented under the 2662-12 coding for solid shims without holes.

Compatibility

• Compatible with John Deere equipment that utilizes plain circular shims for spacing and tolerance adjustments (R49004 variant). References indicate standard use in Deere-maintained assets and service scenarios where precise small-thickness shims are required.
• Alternative part numbers: 2662-12 (solid shims without holes) for the corresponding hole-less, solid shim variant in the same sizing family.
