TROUBLESHOOTING
Clutch slippage that is not repaired will result in serious damage such as excessive wear of the clutch facing, the clutch cover, and even flywheel or clutch seizures.

Problem: Clutch Slippage
The initial stage of clutch slippage is very hard to notice, but the following symptoms are noticeable.
The tractor is not generating adequate power when performing heavy duty operations.
Output is not equal to an increase in engine speed when the engine is accelerated suddenly during operation.

Increased fuel consumption.
When the clutch does not disengage properly, the transmission gears make noise when shifted or shifting of the gears is difficult.

Test Method:
If the parking brakes are applied and the transmission gears shifted to top speed and the engine stops, then the clutch is normal. But if the engine does not stop, it shows that the clutch is slipping.

Probable causes Countermeasures
No play in the release bearing – Adjust.
Broken or fatigued diaphragm spring – Replace.
Excessive wear of clutch facing – Replace.
Oil stained or hardened clutch facing – Repair or replace.
Deviation of flywheel or pressure plate – Repair or replace.
