Inspection

Thoroughly cleanalldisassembled partswithfresh kerosene or
solvent.
• Ifnozzle needle isdamaged orfused, replace nozzle
assembly withanew one.
• Ifend ofnozzle needle isseized orexcessively discolored,
replace nozzleassembly.
• Check nozzle bodyanddistance pieceforproper contact. If
excessively wornordamaged, replacenozzleassembly or
distance piece.
• Check distance pieceandnozzle holderforproper contact.

If
excessively wornordamaged, replacedistance pieceor•
nozzle holder.
• Check nozzle springforexcessive wearordamage. If
excessively wornordamaged, replaceitwith anew spring.

Cleaning
a. Donot touch thenozzle mating surface withyour fingers.
b. Towash thenozzles, useawooden stickandbrass brush
with clean diesel fuel.

1. Remove anycarbon fromexterior ofnozzle body(except
wrapping angleportion) byusing Tool.
2. Clean oilsump ofnozzle bodyusing Tool.

Method B(Using plastigage)
CAUTION:
• Donot turn crankshaft orconnecting rodwhile plastigage is
being inserted.
• When bearing clearance exceedsthespecified limit,ensure
that theproper bearing hasbeen installed. Thenifexces-
sive bearing clearance exists,useathicker mainbearing or
