CAUTION
After removing injection nozzles, be certain to cover dis-
connected ends of injection pipes and nozzle holes in
cylinder head to prevent entry of dirt.
c. Disassembly and Reassembly
(NOTE: Before disassembly, collect data on the nozzle
by testing it for injection pressure (beginning of in-
jection), spray pattern and internal oil-tightness, all in
the manner already described. Throughout the disassembly,
cleaning, and reassembly work, handle each nozzle assembly
with care to protect, in particular, the nozzle tip.)
