ZL20-035002 is recorded as a bush for an XCMG loader joint. The existing record lists XCMG ZL50GN, LW500K and LW500FN applications, but the exact joint position and machine serial still need confirmation. A bushing repair should be planned around the pin, housing bore and lubrication path as one wear system.

Measure the removed bushing at several positions because load can produce oval wear. Also measure the pin and housing bore. A new bush cannot restore correct clearance if the pin is undersize or the housing is enlarged and out of round.
Use the Wear Pattern
One-sided polish often points to load direction or alignment; a dry, galled surface can indicate blocked lubrication; fretting on the outside diameter may mean loss of interference; and broken edges may result from poor installation support. Inspect both sides of the joint, thrust washers, retainers and structural bores.
This page does not publish unsupported material, hardness, interference or running-clearance values. Use verified service data for the exact joint.
Lubrication Path Check
Locate grease holes and grooves in the old bush and housing.
Orient the replacement so the lubrication path remains open.
Clean fittings and drilled passages until grease reaches the intended surface.
Check for hardened grease, dirt or a displaced seal blocking flow.
Use the specified lubricant and service interval.
Installation Without Damaging the Bore
Support the attachment safely and use correct pressing tools. Apply force squarely to the appropriate bushing face; hammering an unsupported edge can deform the bush or damage the housing. Confirm installed depth and lubrication-hole alignment. Finish the bore only if the verified procedure requires it. Fit the inspected pin and retainers, lubricate the joint and check movement through its range.
After controlled operation, recheck heat, movement, noise and grease distribution. Severe play across several joints may require a systematic pin-and-bush survey.

Frequently Asked Questions
Does ZL20-035002 fit every listed loader?
The models are recorded on the source page, but confirm machine serial, exact joint position and dimensions.
Should the pin be replaced?
Measure and inspect it. A worn, tapered or scored pin can create excessive clearance with a new bush.
Why does a bushing turn in the housing?
Possible causes include an enlarged bore, loss of interference, contamination, wrong dimensions or installation damage.
Are pins and seals included?
The supply scope is not defined. Request separate line items.
Quotation checklist: send ZL20-035002, model and serial, joint photo, bush and pin dimensions, housing measurements and lubrication details.
