Common problems

4
  • Engine runs unsteadily and power output is low
    Cause: Inadequate fuel supply, Valve clearance out of adjustment, valve spring broken, Nozzle needles stick, Level of motor oil too high, Level of oil in oil bath air cleaner too high, Inefficient compression due to seized or broken compression rings, or incorrect valve clearances, Cooling fins on cylinders and cylinder heads very dirty, Injectors defective, Injection pump delivery out of adjustment, Blocked blower air intake, Cooling blower V-belt broken, Leaks in lubrication system, Generator speed too low, Generator not charging battery because either the generator or regulator/cut-out is defective
    Fix: Replace fuel filter, air-vent system, clean lift pump strainer, tighten unions, Readjust valve clearances. Have valve spring renewed, Have them checked by a mechanic, Drain off to upper mark on dipstick, Pour off all to reduce level to the mark, Have compression rings and piston checked by a mechanic, Readjust valve clearances, Clean coating fins, vertical ones on cylinder head in particular, Have them checked by a mechanic, Have it readjusted by a mechanic, Clear air intake, Replace V-belt, Stop engine immediately, Check unions on lubricating pump, oil pipe, oil filter and oil pressure gauge for tightness and tighten screws. Otherwise call in a mechanic, Check V-belt tension, Have it checked by a mechanic
  • Engine overheats Engine overheats
    Cause: Engine oil pressure too low
    Fix: Check unions on lubricating pump, oil pipe, oil filter and oil pressure gauge for tightness and tighten screw. Otherwise call in a mechanic
  • Engine fails to start
    Cause: Fuel tank empty, Shut-off valve closed, Fuel filter blocked, in winter through clouding, Fuel lines leaky, Charging indicator lamp does not light up inspite of bulb not being defective, Heater plug indicator does not light up inspite of fully charged battery. On F2L912 W only: Battery low, battery terminals loose or oxidized causing starting motor to run slowly, in winter especially, grade of motor oil used is too viscous
    Fix: Fill up tank and vent, Open shut-off valve and element, vent, Renew filter, use winter grade fuel, Check all fuel lines for tightness and tighten unions, Push home the switch key, tighten battery terminals, check wiring connections, Tighten battery terminals, check or replace coil in heater plug indicator, Have battery tested, clean terminals, tighten and coat with acid-free grease, Crank engine smartly by hand., Use a grade of motor oil to suit the temperature conditions
  • Charging indicator lamp lights up when engine is running Charging indicator lamp lights up when engine is running
    Cause: Generator not charging battery because either the generator or regulator/cut-out is defective
    Fix: Check V-belt tension, Have it checked by a mechanic
