D7 F operation

Hi Ali, been a long time....
Yes, brake forward to engage pinion then snap over center to begin cranking.

Old Magnet,

I did not follow you post .
Does the lever have to be pushed forward after itis snapped , or pulled back.
I am just having hard time remembering and it is causing problem with starting

Thank you

Ali, I think you are talking about the throttle handle on the right side of the dash on a D7F, Am I correct? I always pull it all of the way back but then depress the deaccelarator some before cranking the starter over. You don't want your engine running at too fast of an RPM on startup. If you are having problems with the starter kicking out after a few turns don't forget the starter over-ride button to the left of the dash, just don't over do it and burn up a starter. W. SMITH

OK, let me try again:
1. Starting engine should be running smoothly at high idle rpm
2. Apply sufficient pressure to the starting engine clutch brake to stop the starter pinion from rotating by pushing the clutch and starter pinion control lever all the way forward, then hold it in the brake position for 5 seconds.
3. Engage the starter pinion with the flywheel ring gear and engage the clutch by quickly pulling on the clutch and starter pinion control lever until the clutch snaps over center.

When the diesel engine begins to run, the starting engine clutch and starter pinion automatically disengage.

Hope that gets it.

Old Magnet, I must ask if you have seen a D7F with a pony motor? I have not. The D7F production started in 1970 I believe as the D7E production ended in1969. There may have been some early D7E's (1960) with a pony start but I never saw one on any of the D7E's that I have operated. I would really like to see some pics of a D7F with a pony motor if they exist. Come to think of it I never saw one in the parts book either. W. SMITH

If you do a little digging you will find that the D7F started out with the D333T (with the pony option) and not until sr. # 93N1175 and 94N5192 did the 3306 (3N) come in 1972/3 (no pony). Production did start in 1970 so there are/were about 6,000 or so D7F's with D333T's out there, most with standard direct electric start but the pony was an option. No I don't have pictures on hand, nor have I been looking.

Old Magnet,

This D7 F is a late model with direct start and 3306 engine

OK, then what lever are you referring to?

Pull the lever back past the detent, give it plenty of heat with the heat/start switch, time it with your watch, then try cranking, there is no point in cranking for more than a few seconds, if the motor won't start, check fuel supply to the injectors, then plenty of heat again.
