Inspect flywheel (9, fig. B-3)

for elongated dowel pin holes. Mark oversize or

out-of-round dowel pin holes for repair. Check

flywheel fuel injection pump timing mark (IR

INJ PORT CLOSE) location to be certai n

flywheel has been marked properly. Original

production engine flywheel marks were set at 26

degrees BTC. Improved design engine flywheel

marks were set at 30 degrees BTC at production

and were later remarked with a dotted line to a

26 degree setting. All flywheels must be marked

to the 26 degree setting with a dotted line as

shown in figures 6-40 and 6-41. In the event of a

flywheel having original markings only and

without a dotted line to indicate the proper 26

degree BTC setting, carefully

measure t o

setting and mar k

flywheel with a dotted line as shown in figures 6-
