Check the tractor cylinder sealing performance tips

Farm tractor cylinder pressure gauge in the absence of circumstances, using the following simple method to check . In small tractor as an example: first small tractor parked on level ground , release the shift lever neutral, throttle position on stop oil , brake clutch lever pulled the brake position , with a triangular wood and stones pad to live tires.
With a starting handle crank the engine crankshaft, into the compression stroke , and then continue afterburner crank crank , if they feel the latter half itinerary on the starting handle exerts a strong force or shock reversal , there is a phenomenon not turn shake , indicating cylinder sealing well . If the afterburner during the compression stroke , the compression resistance was enhanced, but can continue cranking , overcome resistance to compression , the compression top dead center over the described sealing performance is poor .
Mini tractors cylinder seal because of poor performance or piston cylinder valve Mifengbuyan wear, can be further checked. If the intake and exhaust pipe at the leak sound can be heard , indicating that intake and exhaust valves and valve seat Mifengbuyan . If the intake and exhaust pipe at the leak did not hear the sound, while the crankcase for leakage sound, indicating the piston , cylinder liner, piston ring wear or piston counterparts and so on. Repair according to the above, a targeted manner.
