Simple Install Tips
To ensure the best performance from your ZF parts, our technical team recommends the following during the installation of the 1250 304 473 shaft:
Bearing Inspection: Always replace the main shaft bearings (front and rear) when installing a new shaft. Reusing old bearings can cause shaft misalignment.
Spline Lubrication: Apply a high-pressure molybdenum disulfide grease to the splines before assembly to prevent “fretting corrosion.”
End-Play Measurement: After assembly, use a dial indicator to check the axial end-play. Correct shimming is vital to prevent gear noise or premature failure.
Seal Protection: Use a protective sleeve over the shaft splines when sliding on the oil seals to avoid cutting the rubber lip.
Cleanliness: Even microscopic metal shavings can ruin a new ZF part. Ensure the gearbox housing is chemically cleaned before reassembly
