Motor Grader Double-Chain Gear Shaft 83513201

Part number 83513201 identifies a double-chain gear shaft listed for a motor grader drivetrain application. This shaft transfers load through its gear or sprocket interfaces, so fitment depends on the complete geometry: shaft length, bearing journals, shoulder positions, splines, threads and mating components.

Before ordering: photograph the full removed shaft, both ends and the readable 83513201 marking. Record the grader model and serial number, then measure from fixed shoulders rather than from worn or damaged edges.

Mechanical interfaces to compare

A shaft can have the correct general shape and still differ at a bearing seat, spline or retaining feature. Compare each interface in sequence from one end to the other. Note circlip grooves, keyways, oil passages, thread direction and any spacer locations during disassembly.

Measurements and photos for confirmation

• Overall shaft length and a dimensioned view of each shoulder position.

• Bearing reference numbers and measured journal diameters.

• Spline tooth count, major diameter and usable spline length.

• Thread diameter, pitch and direction at each threaded end.

• Keyway width and depth, if present.

• Photographs of gear or sprocket interfaces and retaining grooves.

• Machine serial plate plus photographs of the mating parts.

Failure evidence and adjacent checks

Twisted splines, fretting, damaged threads, worn journals or cracking can justify shaft replacement. Also inspect bearings, spacers, retainers, gears, sprockets and lubrication passages. Abnormal tooth wear or repeated bearing damage may point to misalignment, incorrect preload, contamination or damage elsewhere in the drivetrain.

Installation considerations

Keep bearing seats and splines protected from impact and dirt. Assemble components in their documented orientation and use the correct tools for bearings and seals. Do not pull mismatched parts together with fasteners. End play, preload, lubrication and tightening values must follow the applicable motor grader service information. Rotate the assembly by hand where permitted and verify smooth movement before powered testing.

FAQ

Is 83513201 enough to confirm the shaft?
It is the primary reference, but machine serial number and physical interfaces should still be compared before supply.

Can a worn shaft be measured accurately?
Use unworn reference surfaces and record where wear is present. Bearing and spline references can provide additional confirmation.

Should bearings be reused?
Inspect them according to the service procedure. Replace damaged or contaminated bearings and confirm the correct references.

What may cause repeat shaft or bearing damage?
Possible causes include misalignment, incorrect preload, lubrication problems, contamination or damaged mating gears. Diagnose the complete assembly.

Compatibility note: Confirm 83513201 against the machine serial number, shaft dimensions, spline details and all mating drivetrain components.
