Motor Grader Copper Sleeve 819911293 / 85763021
This sleeve is listed in the motor grader parts category with references 819911293 and 85763021. The catalog name “copper sleeve” is useful for recognition, but it does not confirm the alloy, exact installation position or machine model. Correct selection requires the original numbers plus bore, outside diameter, length and lubrication-feature checks.
Measurement note: A worn bore can be larger and an outer surface can be damaged during removal. Record several measurements and identify which areas are unworn before using dimensions for parts matching.
Clearance depends on both mating surfaces
A replacement sleeve works together with a pin or shaft and the surrounding housing. Excessive play may come from wear in any of these parts. Inspect the pin diameter, housing bore, alignment and lubrication path rather than assuming the sleeve alone caused the movement. Use the service limits for the confirmed machine when deciding what must be renewed.

What to document during disassembly
Photograph both reference numbers and the installed orientation before removal.
Record whether the sleeve has a flange, split, oil hole or internal lubrication groove.
Measure bore, outside diameter and length at more than one position.
Inspect the mating pin or shaft for taper, scoring, corrosion and oval wear.
Check the housing bore and nearby grease passage for damage or blockage.
Include the machine model, serial number and parts-diagram position in the enquiry.
Wear patterns and root-cause checks
One-sided wear can indicate misalignment or a bent mating part. Dry polishing, scoring or discoloration may point to lubrication or contamination concerns, but the cause should be confirmed by a technician. If a grease path is present, make sure it is open and aligned with the sleeve feature during installation.
Installation planning
Do not hammer directly on a finished sleeve surface. Use the machine repair procedure and suitable installation support so the part enters squarely. Confirm the specified fit, orientation and final inside dimension after installation. If the process reduces the bore or requires finishing, follow the manufacturer’s service data rather than using a general clearance assumption.

FAQ
Which motor grader uses sleeve 819911293 or 85763021?
The available record does not state an exact model. Confirm the machine serial number, parts diagram and original sleeve.
Are the two numbers guaranteed equivalents?
They are grouped in this product record, but original markings and dimensions must still be checked.
Does “copper sleeve” confirm the alloy?
No. The catalog description is not a verified material certificate or chemical specification.
What dimensions should I send?
Provide bore, outside diameter, length, flange dimensions, groove and hole locations, plus photos of the sleeve and mating pin.
Compatibility note: Final selection depends on the original references, assembly position and measured interfaces.
