Propellor removal using pilgrim method

Advantages:The advantages of the Pilgrim method are; that engine torque maybe transmitted without loading the key, where fitted.Also thrust produced is transmitted through a hydraulically pressurized nitrile tyre, which is applied to the propeller to force it onto the shaft. procedure- mounting, the surface must be dry
and degreased.calculations must be done for getting the required push hydraulic pressure at right temperature.  the hub movement must be properly measured using a dial gauge. The pilgrim nut has an internal rubber tube which is inflated by hydraulic pressure.forces a steel loading ring into the hub. if outward movement of ring exceeds more than 1/3rd of ring, it may rupture. the hydraulic fluid in the ring is flushed by turning the nut. the propeller is removed by using the nut in the reverse direction.

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).

M/e trouble-what to check if Engine is not starting on air and fuel?

Engine not starting on Air: - * Low air bottle pressure or airline valve may be shut. * Air bottle isolating valve or automatic valve or distributor not functioning. * Control air valves faulty or less control air pressure. * Starting air automatic valve jammed. * Turning gear engaged. * Reversing has not taken place completely. * Control valve for fuel or start is not in its end position. * Bursting diaphragm(disc) on start airline damaged. * Fuel lever on maneuvering stand not on remote mode. * Auxiliary blower not running or not on ‘auto’ mode. * Emergency stop has activated. * Interlock is operated. *Cylinder air start valve defective or sticky. *Piston not in firing mode.   Engine not starting on fuel: - *Less fuel in service tank. * Fuel Oil filter is chocked. * Fuel Oil supply pumps not delivering required pressure. Or fuel pump tripped. * Puncture valve still active. *Fuel oil temperature to low. * Fuel level on local maneuvering stand, is not on remote stand. * Fuel rack...
