The Tractor is a New Holland 545D. I down loaded a book. I Have been a Diesel Mechanic for 30 years ( truck). The timing say 29 degrees. The book only talks about lining up 3 cyl marks on timing gear and with pump in lock position,tighten pump drive nut. This makes no sense to me! I see no timing marks on engine. I would like to have pump locked up.turn engine to 29 degrees then lock up timing grear...this would make more sense.

We got the engine running.This engine has no timing marks or dowl pins or key way for pump timing gears. You set timing gear on #3 cyl. with the pump pinned (like a old Cat pump)We then tighten front nut to lock pump timing in place.Then unpin injection pump.I hate this but is only way that the service manual gives the info.I would have liked to have degree marks to set a perfect timing. This seems very sloppy to me. I was taught that you can only be 1 degree off. The engine runs good now...Thanks for your help.
