Astuce d'installation simple:

1. Check Spline Fitment: Before final assembly, slide your sliding sleeves and gears onto the new 34-spline shaft by hand. They should move freely without binding. If you feel resistance, check for debris or burrs on the mating components.

2. Replace Pilot Bearings & Seals: A new main shaft should never be paired with old bearings. Always replace the main shaft bearings and the input shaft pilot bearing to prevent misalignment that could snap the shaft under load.

3. End-Play Calibration: Proper shimming is vital. Use a dial indicator to measure the axial end-play of the shaft once it is seated in the housing. Incorrect clearance will lead to gear “jumping” or excessive heat buildup.

4. Lubricate During Assembly: Use a high-quality assembly lube on the splines and bearing surfaces. This protects the metal-on-metal contact during the critical first few seconds of operation before the pump circulates the transmission oil.
