SECTION 4. TROUBLESHOOTING
1.PROBLEM :Clutch slippage.
The initial stage of clutch slippage is very hard to notice,but the following symptoms
1) The tractor is not generating adequate power when performing heavy duty operations.
2) Output is not commensurate to increate in engine speed when the engine is accelerated suddenly during
operation.
3) Increased fuel consumption.
These symptoms are apt to be mistaken for engine problems.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
seizure.
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.
