The oil pump is driven by the distributor drive gear on a V8.The oil pump is driven by the distributor drive gear on a V8.
The oil pump drive gear, which is driven by the camshaft, drives the distributor.The oil pump drive gear, which is driven by the camshaft, drives the distributor.
Either the gear on the end of the distributor shaft is chewed off or the gear that drives it is . Possibly broken cam.
There is a hexagonal rod between the oil pump and distributor. As the distributor turns so does the oil pump. The newer DIS engines use a distributor plug that retains the drive gear for the oil pump rod.
they are gear to gear driven.
If it has a distributor, then that is what drives the oil pump. The camshaft is what makes the distributor turn.If it does not have a distributor then the gear on the oil pump slides over the front of the crankshaft and turns when the crankshaft turns and that is what makes the oil pump work. Early 99 models had a distributor, and the late 99 did not have one.
You need to turn the motor so the first piston is at top of the cylinder to remove the distributor.
Typical: Remove distributor. Use punch to tap roll pin from gear at base of distributor. Use an arbor press (not a hammer) to press distributor mainshaft out of gear. Shaft will then easily come free of the distributor. If a hammer is used, now replace the complete distributor. Unbolt the pickup and replace. Reinstall shaft and gear being sure that gear hole aligns with shaft hole. Install a new roll pin. Install in vehicle. Set ignition timing.
Remove the clamp for distributor. Remove distributor, making a note how it is orientated for #1 position. Also check which way slot in drive faces for reasssembly. With a strong magnet, reach down in distributor hole and allow magnet to pull up on distributor drive gear...if it is reluctant to move...rotate drive gear back and foreward with a screwdriver in the gear center, while pulling up with the magnet. Drive also turns the oil pump and it may need a slight engine turn to free it up..
Is there just a gear or a timing chain on a 1985 ford bronco 11 2.8 liter V 6.
no belts or chains gear driven only
One thing I know is that the Ford 2.8 L V6 engine doesn't have a timing chain or timing belt . It has a large gear on the end of the camshaft that meshes (spelling ? ) with a smaller gear on the end of the crankshaft - (Helpfull)
