The distributor shaft gear is made from hardened 'tool' steel which can become brittle, I broke one on my 2001 Blazer myself. Like any other part, they can eventually become weak and break. The only other causes are a defect in manufacturing (which usually appears much sooner) or improper installation (if you've had any work done requiring the distributor's removal - they have to be properly seated and/or shimmed when installed).

How do I remove distributor shaft out of distributor for 1958 edsel

there is a roll pin that holds the drive gear to the distributor shaft. if you can note the position of the gear or take a picture of it before removal to help when reassembling. then pull the shaft out of the housing, it may be hard to remove because of the old oil build up on the shaft so you may have to clean and spray the shaft to aid in removal. its been a while so there may be a lock clip at the base of the distributor shaft were it is close to the housing to keep the shaft from running up into the distributor cap causing damage.

Why *** i need to change cam belt and tensioner at rhe same time? is it a must

You buy a complete kit

That includes the water pump,timing belt,all
idler pulley's ,so you don't have to go back
there when the water pump fails

Just like you replace brake hardware, sometimes,
as it rusts,wears & heat cycles

You do your belt at 140,000 km (84,000 miles) about
every 7 years (12,000 per year)

How to fix distributor gear

Without better information, I will assume you are saying the distributor gear has teeth missing or stripped. While replacing the gear is easy, you should first determine why it is damaged. You failed to mention what engine you are working on, but be aware that roller cam engines require a different distributor gear than non-roller types. In either case, bring the engine to TDC with cylinder #1 in firing position. This can be found by either putting a compression gauge in the # 1 spark plug hole, or have someone gently put a finger over the plug hole to feel when compression is pushing air out. Next, mark the position of the distributor body to the engine, and remove distributor and examine gear to find the roll pin which holds the gear in place. Set up some wooden block to hold the end of the gear without blocking the roll pin and using a punch smaller than the pin, hammer the roll pin out being careful to catch the pin on a cloth beneath your work. Obtain the correct replacement gear and install it on shaft using a small screwdriver to hold it in place. Check for excessive end play of distributor shaft and add shims if needed. Reinsert roll pin, then reinsert distributor, making sure that the rotor points to #1 plug connector on cap. The distributor will rotate some as it drops into place, so this may take more than one try. Note: if the distributor will not go all the way in, it may be necessary to use a flashlight and look down the hole where distributor goes to see the shaft the bottom of distributor must align with. You can use a long screwdriver to turn the oil pump drive shaft if needed. Install distributor hold down and tighten just enough to allow some resistance to turning distributor. Start engine and adjust timing.

Final note. Reasons for distributor gear damage include: stuck oil pump; bad cam shaft gear area, bad bearings in distributor or other distributor problem; and even a very worn timing chain causing crazy vibration (rare).

My distributor on my truck was not fastened down for weeks what damage could result from this?

If the distributor came out of the hole, the gear on the bottom of the shaft could have been damaged. Otherwise, it should be ok and just in need of having the timing set.

1988 Ford Bronco II How to change Distributor Pickup Coil

how do you remove the gear on the end of distributor shaft so the pickup coil can be replaced

Turns over but dont start. 98 chevy blazer

First verify if you have spark using a tester,then verify you have fuel
now verify timing heres how;

To get #1 compression remove plug and put your finger in the hole and have someone crank the engine until you feel your finger being pushed off by the air pressure. Now line up the timing mark.

Rotate the number 1 cylinder to Top Dead Center (TDC) of the compression stroke.

Align white paint mark on the bottom stem of the distributor, and the pre-drilled indent hole in the bottom of the gear (3).
Notice: The ignition system distributor driven gear and rotor may be installed in multiple positions. In order to avoid mistakes, mark the distributor on the following components in order to ensure the same mounting position upon reassembly:

• The distributor driven gear

• The distributor shaft

• The rotor holes

Installing the driven gear 180 degrees out of alignment, or locating the rotor in the wrong holes, will cause a no-start condition. Premature engine wear or damage may result.

Notice: Installing the driven gear 180 degrees out of alignment, or locating the distributor rotor in the wrong holes, may cause a no-start condition. Premature engine wear and damage may result.

With the gear in this position, the rotor segment should be positioned as shown for a V6 engine (1) or V8 engine (2).
- The alignment will not be exact.

- If the driven gear is installed incorrectly, the dimple will be approximately 180 degrees opposite of the rotor segment when it is installed in the distributor.

Using a long screw driver, align the oil pump drive shaft to the drive tab of the distributor.
Guide the distributor into the engine. Ensure that the spark plug towers are perpendicular to the centerline of the engine.

Once the distributor is fully seated, the rotor segment should be aligned with the pointer cast into the distributor base.
- This pointer may have a 6 cast into it, indicating that the distributor is to be used on a 6 cylinder engine or a 8 cast into it, indicating that the distributor is to be used on a 8 cylinder engine.

- If the rotor segment does not come within a few degrees of the pointer, the gear mesh between the distributor and the camshaft may be off a tooth or more.

- If this is the case, repeat the procedure again in order to achieve proper alignment.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the distributor mounting clamp.

Tighten the distributor clamp bolt to 25 N·m (18 lb ft).

Install the distributor cap.
Install two NEW distributor cap screws.

Tighten the screws to 2.4 N·m (21 lb in).

Install the electrical connector to the distributor.
Install the spark plug wires to the distributor cap. Refer to Spark Plug Wire Harness Replacement
Important: If the Malfunction Indicator lamp is turned on after installing the distributor, and a DTC P1345 is found, the distributor has been installed incorrectly.
Repeat Installation Procedure 2 for proper distributor installation 
hope this helps

Engine turns over but no spark at the plugs. checked coil ok changed ignition moudle no luck changed rotor no luck. checked voltage from coil to cap getting 12vdc. checked voltage going to and coming out...

You can change pick-up coil, you need to remove distributor (mark where rotor is pointing first) Then you need to remove pin in cam gear on end of shaft to remove gear so you can remove shaft from housing. Then you can replace pick-up coil. Install in reverse. Note when removing distributor rotor will move to the right as you lift distributor out, move rotor to right of mark you made when installing distributor back in.

How to set timing on toyota corolla 1.6 engine 4ac?

First the timing is easier to set with that big metal thing removed on the side of the engine. Next I set the No# 1 cylinder to TDC. If you remove the cap to the distributor it helps. They are 8mm bolts three of them.

Pull the plug and insert a platstic straw in the No 1 cylinder When it stops going completly up its at TDC I set it to 10 degrees BTDC by watching the marks on the front cranshaft pulley Never turn the engine backwards the timing belt cold come off. Sometimes its easier to remove the other plugs and turn it by hand.

Next remove the distributor Yes completly, not just the cap. Look at the 4 poles or tabs on the shaft inside the distributor and notice how they align up to the stationary pick up pole inside the distributor as the rotor shaft rotates. Put the rotor part on the shaft, and mark the spot when the rotor is pointing to the No1 spark plug wire position as it passes one of these poles This is your new timing mark.

Now put the distributor back in so the rotor is pointing to the No 1 postion or this mark. You now have a timing of 10 degrees BTDC or where ever the crank was set.

Tip: As the distributor goes in it will turn one way as it engages the gear So yu must lead the mark when you go to put the ditributor in by turning the shaft off your mark.

The distributor will rotate too, so you can align the timing mark you made on the distributor to the rotor shaft. I use white paint applied with a small touch up brush for my mark.

Also your mount bolt should fit in the slot cut in the bottom of the distributor to tighten it in place.
