datzenmike Posted September 20, 2019 Report Share Posted September 20, 2019 Engaging means clutch pedal up, clutch gripping and turning the transmission input shaft with the engine. Disengaged is pedal down to the floor and engine and transmission disconnected. How is the clutch not working when starting???? 1 1 Quote Link to comment

DanielC Posted September 20, 2019 Report Share Posted September 20, 2019 521 trucks did not have a neutral safety switch. Back in the 1970's, we did not have "nanny cars" that had on dash back up cameras, lane departure warnings, tire pressure monitoring systems. It was assumed you knew enough to put the transmission in neutral, and push the clutch pedal in when cranking the engine. 1 Quote Link to comment
datzenmike Posted September 20, 2019 Report Share Posted September 20, 2019 AAAHHHHHH safety switch DUH. 720 was the buzzer for key in ignition, probably the clutch interlock too. 1 Quote Link to comment

It was an accessory to pull a stalled vehicle off the tracks before being hit by an oncoming train. Then the idea of a self starter vs hand cranking hit home. 1 Quote Link to comment
datzenmike Posted September 20, 2019 Report Share Posted September 20, 2019 My '70 Dart had an interlock. I disconnected it because I wasn't an idiot.... and I could crank the car off the RR tracks if I had to. The real reason was the thrust bearing on the crankshaft grinding away with little oil pressure at 20 below. 1 Quote Link to comment
FatDatSun Posted September 22, 2019 Author Report Share Posted September 22, 2019 Thanks everyone, yes I meant did i have to step on the clutch to start. If not, great! If did, I just wanted to know to repair or leave it alone. Life - If it ain't broken, leave it alone. If you ain't happy ftw and go big. 1 Quote Link to comment
