XCMG Double-Row Sprocket 800107297 / 85513022
This double-row sprocket is listed with part references 800107297 and 85513022 in the motor grader parts category. The available record does not identify an exact machine model, material grade, heat-treatment specification or installation position. Those details should not be assumed. Correct matching should use the original markings and measurable chain-drive geometry.
Parts-matching tip: Count the teeth twice and photograph the sprocket beside a scale. Record the bore, hub, keyway or spline, row spacing and mounting features before requesting a replacement.
A sprocket is defined by geometry
Two double-row sprockets can look similar while using a different pitch, tooth profile or shaft interface. References 800107297 and 85513022 are important catalog clues, but tooth count, chain size and centre-line spacing provide physical confirmation. If the worn part has sharp or hooked teeth, measure an unworn area where possible and include photos of the mating chain.

Wear patterns worth documenting
Uneven polishing, hooked teeth, side wear or damage concentrated on one row can point to alignment, tension or chain-condition problems. Replacing only the sprocket without checking the mating chain and shaft alignment may leave the underlying cause unchanged. Record axial play and inspect retainers or bearings according to the machine service procedure.
Measurements to send with an enquiry
Clear photographs of every stamped or cast reference number.
Number of teeth on each row and the chain reference if readable.
Outside diameter, bore diameter and total width.
Distance between the two tooth-row centre lines.
Hub shape, keyway, spline or bolt-hole details.
Machine model, serial number and a wider photo of the installed location.
Installation planning
Before removal, mark component orientation and chain routing. Inspect the shaft, key, fasteners, chain and adjacent guides for damage. Use the service procedure for alignment, retention and tension. After assembly, rotate the mechanism slowly through a complete cycle to check engagement before applying normal working load.

FAQ
Which XCMG model uses 800107297 or 85513022?
The current source record does not state an exact model. Supply should be checked against the machine serial number, parts catalog and original sprocket.
Are the two references guaranteed equivalents?
They are grouped in this product record, but physical measurements and original markings still require confirmation.
Can a worn sprocket be matched by outside diameter?
No. Tooth count, pitch, row spacing and shaft interface are also necessary.
Should the chain be inspected at the same time?
Yes. Wear or incorrect alignment in the mating chain can damage a replacement sprocket and affect engagement.
Compatibility note: Do not order from appearance alone; verify reference numbers and all critical dimensions.
