5.HOW TO CHECK MAIN BEARING CLEARANCE?
carryout tool box meeting and risk assessment
A: Stop M/E and shut off main starting airv/v and starting air distributor
Engage turning gear
Just stopping engine, while L.O pp still running, check oil comes fromcrosshead bearing and guide shoes condition
Turncrankthrow to a suitable position and stop L.O pp
Check top clearance with a feeler gauge, the clearance is measured atboth fore and aft part of the bearing, if increase of clearance since previousreading larger than 0.05mm the bearing should be open up inspection, mainbearing top clearance max 0.85mm, min 0.55mm
Check bearing edges with feeler, check bearing metal fragments in theoil pan, large thick pieces will be found during crankcase inspection and smallthin pieces can enter the filter
6.WHAT IS THE MAIN ENGINE PISTON TAKEOUT PROCEDURE?
carryout tool box meeting and risk assessment
A: Stopped engine, block startingmechanism, shut off starting air, engage turning gear, shut off cooling water,fuel oil and L.O
Turncrosshead down for enough to access to the piston rod stuffing box and pistonrod screws. Loosen stuffing box flange innermost screws and piston rod screws.Mount two distance pieces on the piston rod food to protect lower scraper ringand to guide stuffing box, dismount cylinder cover.
Turn crosshead towards TDC, checkingstuffing box lands correctly on the distance pieces, turn to TDC, the top ofpiston now is free of cylinder liner
Clean lifting groove of piston crown andmount the lifting tool--fit two fixed claws of tool into lifting groove ofpiston and then fit the third adjustable claw and tighten
Lift piston out of cylinder liner
7.Why an M/E can not start and what will you do?
A: M/E fails to turnby air: staring air pressure too low- check and start air compressor,
V/v on starting air receiver closed-open, v/v to starting airdistributor closed-open,
Main starting v/v locked in closed position –open, turning gear engaged-disengage turning gear, control selectors arewrongly set-correct setting, control air system no pressure-check pressurenormally 7 bar clean filter, starting air v/v in cylinder cover defective-replace or O/H v/v
M/E turns on starting airbut stops run on fuel oil: puncture v/v not air ventafter all replaced or O/H-air vent puncture v/v, shut down of engine-checkpressure and temp, reset alarm, sluggish in the manoeuvring gear-lubricate themanoeuvring gear, ensure the fuel pumps, rod connections and bearings aremovable, faulty adjustment of manoeuvring gear-check fuel pump index, governorair booster not supply oil pressure to governor during starting airperiod-check governor function, the preset speed setting pressure to governoris too low or too short- the pressure shall be setting between 1.6-2.0 bar andmaintained about 6sec, fault in governor-check governor oil prs, check limitingfunctions correctly adjusted and etc
8.WHAT DO YOU CHECK IF M/E ALL CYL EXH. TEMP. HIGH?
A: Scavenge air temp high due to air coolerdirty or cooling water not enough or cooling water high temp
Fouled air and gas passages due to T/C dirty
Heavy load or rough sea
Fuel quality not good
Wrong position of camshaft, check chain tension
9.WHAT DO YOU CHECK WHEN CARRY OUT SCAVENGE SPACE INSPECTION?
carryout tool box meeting and risk assessment,enclosed space permite,toxic gas checksuch as O2,H2S,CO,BENEZE
A: Inspect piston, rings and cylinder wallby piston is nearest BDC, check piston ring micro-seizure, scratched, sticking,breakage, carbon deposit condition
Check total clearance between piston rings and ring grooves
To reduce risk of scavenge box fire, remove any oil sludge and carbondeposits in scavenge air box andreceiver
Check oil sludge drain pipe chock or not
10.HOW DO YOU DETECT SCAVENGE SPACE FIRE, AND IF FIRE WHATS YOUR ACTION?
A: DETECT:Exhaust temp increase of affected cylinder, scavenge air box fire detector alarm will coming setpoint 80 °C, rpm slow down 120 °C
T/C may surge
Smoke out from T/C airinlet filter when surging
The scavenge air box somuch hotter
Violent blow-by willcause from scavenge box drain cock
ACTION:
ask Bridgefor permission to stop engine
Stop F.O and L.O oilsupply
Open the fireextinguishing steam v/v and neighborhood cyl. steam v/v to prevent firespreading
Do not open scavengeair box before the fire extinguished and cooled down to below 100 °C
Remove all sludge anddry deposits and clean piston rod cyl liner
Retighten staybolts of scavenge air box
