SINOMACH 732T Drive Shaft Assembly 730-22-A10000
Part number 730-22-A10000 identifies a drive shaft assembly listed for the SINOMACH 732T motor grader. A replacement must connect correctly at both ends and operate through the machine’s working angles. Confirm the shaft length, flange or yoke design, pilot features, bolt pattern, spline and the original orientation before ordering.
Workshop evidence: Photograph the complete shaft while still installed, then capture each end separately. Mark relative orientation before removal so the assembly arrangement is documented.
Driveline matching begins at both ends
Two shafts can have a similar tube and still use different flange pilots, bolt circles or joint sizes. Start with 730-22-A10000 and the 732T serial number, then compare the compressed or installed length using a consistent reference point. Record whether a sliding spline, companion flange or yoke is present without assuming interchangeability from one dimension.

Inspection clues before replacement
Vibration, clunking, joint play, damaged splines or missing balance weights can justify driveline inspection. These symptoms may also involve mounting flanges, bearings, axle inputs or incorrect joint phasing. A technician should inspect the complete driveline and check runout or joint condition using the machine service procedure.
Measurements and photos to provide
Full view of the shaft and readable 730-22-A10000 marking.
Installed or fully compressed reference length with the method shown.
Flange outside diameter, pilot diameter, bolt count and bolt-circle measurement.
Yoke and universal-joint dimensions where applicable.
Spline count, outside diameter and usable length if a spline is exposed.

Removal and installation planning
Support the shaft before releasing fasteners and mark its installed orientation. Protect splines and sealing surfaces from impact and contamination. Do not pull a misaligned flange into place with bolts. Tightening, lubrication and joint phasing should follow the 732T service information. After installation, rotate the driveline by hand where the procedure permits and conduct a controlled low-speed check for interference or vibration.

FAQ
Is 730-22-A10000 confirmed for every SINOMACH 732T?
It is listed for 732T, but confirm the machine serial number and original shaft interfaces before supply.
Can a drive shaft be matched from overall length alone?
No. End connections, pilot and bolt patterns, joints, spline and operating clearance must also match.
Does vibration always mean the shaft tube is bent?
No. Joint wear, flange runout, incorrect phasing and adjacent driveline components can also cause vibration.
What should be inspected with the shaft?
Check mating flanges or yokes, fasteners, universal joints, splines, bearings and surrounding clearance.
Compatibility note: Use the part number, 732T serial number and complete end-interface measurements for final matching.
