XCMG Crawler Crane Drive Sprocket Ring - Photo Reference
This page shows a drive sprocket ring photo reference for an XCMG crawler crane undercarriage. The ring engages the track chain and transfers travel torque from the final-drive side into the crawler track. Exact fitment cannot be confirmed from appearance alone and must be checked against the crane and dimensional data.
Why Sprocket Geometry Is Critical
The tooth profile must match the track pitch and bushing contact pattern. Tooth count, root shape, pitch diameter and mounting geometry all affect engagement. Installing a ring with similar outside dimensions but different tooth or bolt geometry can cause poor meshing, rapid wear or assembly problems.
Data Required for Comparison
XCMG crane model and complete machine serial number
Original part number, casting marks or stamped references
Number of sprocket teeth and clear photos of the tooth profile
Outside and inside diameters
Bolt-hole quantity, hole diameter and bolt-circle diameter
Ring thickness, mounting-face profile and any locating step
Wear Pattern Checks
Photograph several teeth rather than only the most damaged area. Hooked tooth tips, uneven flank polishing, chipped edges or an asymmetric contact band can indicate sprocket wear, track-chain wear or alignment issues. The mating track pitch and bushing condition should be reviewed before replacing the sprocket ring alone.
Fitment and Installation Notes
Clean the mounting face and measure from unworn reference areas. Record whether the ring is a separate bolted component and photograph its orientation before removal. We do not claim an exact material, hardness, torque value or interchangeability without a confirmed technical reference. Fastening and installation procedures should follow the applicable machine service information.
Export Protection
Tooth edges and machined mounting faces need protection against impact and corrosion. A heavy sprocket ring can be fixed to a reinforced pallet or plywood base with separators that prevent metal-to-metal movement. Identification labels should remain visible for incoming inspection.
Frequently Asked Questions
Is tooth count enough to identify the sprocket ring?
No. Pitch, diameters, bolt pattern, thickness, locating features and the machine serial number are also important.
Should the track chain be inspected at the same time?
Yes. A worn chain can change the contact pattern and shorten the service life of a new sprocket ring.
Can you compare a used sample with the pictured part?
Yes. Send front, rear, side and tooth-profile photos together with measurements taken from the removed sample.
