f o r 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 certain

flywheel has been marked properly. Original

p r o d u c t i o n engine flywheel marks were set at 26

degrees BTC. Improved design engine flywheel

m a r k s were set at 30 degrees BTC at production

a n d were later remarked with a dotted line to a

2 6 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

w i t h o u t a dotted line to indicate the proper 26

degree BTC setting, carefully measure to

determine correct degree s e t t i n g a n d m a r k

flywheel with a dotted line as shown in figures 6-

40 and 6-41.
