Common 3LD Component Issues to Check
These are general diagnostic indicators. The complete engine should be inspected because the visible damaged component may not be the original cause of failure.
Low Oil Pressure
Check oil-pump drive, internal clearance, pickup, oil passages, bearing clearances and oil condition before replacing the pump.
Crank-Support or Bearing Wear
Inspect bearing fit, housing dimensions, crankshaft journal condition, alignment and lubrication supply.
Rocker-Cover Oil Leakage
Check cover flatness, gasket condition, sealing surface, breather operation and tightening sequence.
Hard Starting
Verify compression, fuel delivery, injection timing, starter-pulley engagement and flywheel movement.
Restricted Fuel Flow
Inspect the fuel tank, filter bowl, element, pipes, water contamination and air leakage at connections.
Smoke or Low Compression
Check piston clearance, ring condition, cylinder wear, valve sealing, air intake and injection condition.
