Method for Adjusting the Dongfanghong Clutch

[MacHaven]

For the Dongfanghong clutch, first adjust the clearance between the brake pressure plate and the brake disc, then adjust the pedal free travel. Clutch Slipping: Symptoms include slow starting in low gear, difficulty starting in high gear, and occasional shaking; reduced tractor traction; when the load increases, the vehicle speed fluctuates or even stops, but the internal combustion engine sound remains unchanged; in severe cases, the clutch overheats, the friction plate smokes, and there is a burnt smell. Causes and Solutions: Oil contamination on the friction plate surface. This is mainly caused by damaged oil seals or other sealing devices leaking lubricating oil, or improper maintenance with excessive oil injection. Identify the source of the contamination, eliminate it, and then clean the clutch. Insufficient or no free clearance in the clutch. Readjust the clearance. Broken or weakened pressure springs. Replace the springs. Worn friction plate. If the friction plate is unevenly worn, severely burnt, or too thin with exposed rivet heads, replace it; if the wear is minimal and the rivet heads are buried at least 0.5 mm deep, replacement may not be necessary. However, if the rivets are loose, re-rivet or replace them with new rivets. If the friction plate is slightly burnt, smooth it with sandpaper. Warped driven disc or excessive unevenness of the flywheel and pressure plate surfaces should be corrected and repaired. Loose or broken return springs should be replaced.
