Hi guys,

My buddys kid just bought a 73 ford f350 to use as a work truck, . It has a 460 in it. It looked pretty clean and it ran, perfect for the kid, whose own truck busted a timing chain and is waiting for a new head.

On the way home from buying the truck, the cable that goes to the starter grounded out on the frame and started a fire, which they quickly doused and bandaged for the rest of the drive home. When they started it, something broke and they ended up towing it home.

Apon closer inspection, we found that one motor mount (passenger side) was missing the bolt that secures it to the frame, the bolt that ties the trans to the cross member was missing plus the bolts that hold the cross member to the frame were loose, the float in the carb stuck and would sometimes overflow, the linkage for the accelerator was home made and tied on with a wire and to top it off, the starter was a dinky push button kind wired to the coil with speaker wire.

Hey, the kid was desperate for a work vehicle.

Anyways, I (who is a mechanic by necessity only) help get the new motor mounts on, the cross member bolt for the trans on, the cross member bolts tightened, bolted on a brand new carb, replaced the starter cable, and bolted on a new starter. All that took the better part of the day and it ended there.

Today, they have me come over again to help change the gear on the dist which apon inspection had a sizeable chunk taken out of it.

I did what was requested of me, I replaced the damaged gear on the dist with minimal effort.

We then manually turned the motor to TDC, verified the #1 cyl from the book and the direction the rotor should be pointing and reinstalled the dist.

Only the dist doesnt turn when we manually crank the motor.

I am at the end of my skill level when it comes to auto mechanics regarding this issue, so here I am looking on the net for help.

Asking a couple of my buddies produced:

1: Oil pump is locked up. - Inspect and replace if damaged?

2. Check timing chain. Inspect and replace if damaged?
-

I personally want to drop the oil pan and remove any fragments I find, but I know there are prolly more things we should be checking.

Any advice would be appreciated.

Check the camshaft could have broken or the gear on it that turns the distributor drive gear is damage

I'M ONE OF THOSE NECESSITY FELLERS TOO! I DO MY STUFF RIGHT THOUGH. OK, EZ STUFF TO DO, TO AT LEAST SEE WHAT'S-A-HAPPENIN'. LET'S SNATCH THE DISTRIBUTOR, I KNOW WHAT YOU SAID, BUT I AIN'T THERE. DID YOU DRIVE A ROLL PIN THRU THE GEAR TO HOLD IT ON, PREVENT SPIN-AGE? NEXT, USING A DECENT MIRROR AND A BRIGHT LIGHT, CAN YOU SEE THE DISTRIBUTOR DRIVE GEAR ON THE CAM, WAY DOWN IN THE HOLE? ARE THE TEETH STILL ON IT?---GET JIMBOB TO TURN IT OVER BY HAND, WHILE YOU LOOK IN THE HOLE. IS THE CAM GEAR TURNING. IF NOT, YOU MIGHT LOOK IN EVERY AVAILABLE HOLE IN THE VALVE COVERS. CAN YOU SEE OR TOUCH ROCKER ARMS. WITH JIMBOB TURNING IT OVER AGAIN BY HAND DO THEY MOVE UP AND DOWN (VERIFYING THE TIMING CHAIN BROKE/ NOT BROKE AND MOVING THE CAM). IF ALL SEEMS WELL, IS THE DISTRIBUTOR CORRECT (LENGTH) OR FULLY SEATED DOWN (MEANING: DID YOU TWEAK THE OIL PUMP AROUND, WITH A LONG SCREWDRIVER, UNTIL THE FEMALE SLOT MATED WITH THE DISTRIBUTOR'S MALE END, SO THE DISTRIBUTOR WOULD FALL IN COMPLETELY?) YOUR TURN.I DID THIS ALL BY MYSELF FROM NOT MUCH TO BEGIN WITH, (SHOWING MY SELF CERTIFIED REAR LAWN VEHICLE TECHNICIAN CREDENTIALS)

Hey Sarge you need Johnboy to recheck it-by manually turning crank over and watching the two fingers moving up and down-movement noted -it ends on the drive gear side of the camshaft-earlier the drive gear on the distributor was replaced

ROGER, WITH MY SCRLVT LICENSE, I SHOULDA THOUGHT OF ALL OF THAT! BUT I WILL ADD THIS: WE CAME ACROSS A TRUCK THAT THE GEAR HAD BEEN REPLACED, IMMA GUESSING EITHER "MEGA OIL VISCOSITY" OR "OIL PUMP, GROUND UP SOMETHING HARD" OR "OIL PUMP BINDING" THE NEW GEAR DID SPIN AND SHEARED THE ROLL PIN (COULDA BEEN A "SOFT" ROLL PIN). ANYWAY, THE 3 OF US TRYING TO FIGGER IT OUT, TOOK HIS WORD ON THE "NEW-NESS". FINALLY WE SNATCHED MR. DISTRIBUTOR OUT, ALL LOOKED GREAT! BUT WHEN I REALLY "GOT DOWN ON IT" I WAS ABLE TO TURN THE GEAR WITH MY HAND, HOLDING THE SHAFT STILL WITH CHANNEL LOCK PLIERS. MORAL OF THE STORY: IF THE PIN IS SHEARED, ITS NOW IN 3 PIECES, 2 IN THE GEAR HOLES (LOOKS NORMAL), 1 IN THE CENTER SHAFT. GOTTA PULL THE GEAR OFF OF THE END, TO DRIVE OUT THE PIECES. OIL PUMP TURNED EZ, WITH A SCREWDRIVER. WE REPLACED IT WITH A HARDENED PIN, NO MORE PROBLEMS. ONCE AGAIN, YOU WERE OVER IN THE VW, BUICK, CHEVY, AUDI SECTIONS, WHEN I STARTED HUNTIN' AND PECKIN' ON THIS ONE. ONCE AGAIN YOU BEAT ME TO SUBMIT! WHATS THE DEAL WITH A NEW UNIT PATCH DAILY? LET'S SEE SOME JEEPNEYS!---THE MEDIC
