What is the firing order for a 1995 bucik cetury 3300 block motor? Harmonic Balancer was replaced and I need to know if it will throw off the timing.

I had got help from its manual from online

Here's the site link I am sure they will help you

What make vehicle ? model an year too. Some vehicles have two crankshaft position sensors .

24X and 7X Crankshaft Position Sensors/Harmonic Balancer Interrupter Ring

One sensor is in the side of engine block an the other is behind harmonic balancer

The harmonic balancer on these engines is now press fit onto the crankshaft and requires the use of Tool J-38197 for removal. The torque specification to be used during installation has also been revised. The procedure to be used when replacing the crank sensor is as follows:

REMOVAL

1. Disconnect serpentine belt from crankshaft pulley.



2. Raise vehicle on hoist.



3. Remove right front tire and wheel assembly.



4. Remove right inner fender access cover.



5. Using 28 mm socket, remove crankshaft harmonic balancer retaining bolt.



6. Remove crankshaft harmonic balancer using Tool (J-38197).



7. Remove foreign object deflector (DO NOT use pry bar).



8. Disconnect sensor electrical connector.



9. Remove sensor and pedestal from block face.



10. Remove sensor from pedestal

INSTALLATION

1. Loosely install crankshaft sensor on pedestal.



2. Position sensor with pedestal attached on Tool J-37089.



3. Position tool on crankshaft.



4. Install bolts to hold pedestal to block face, torque to (18-26 lb. ft.).



5. Torque pedestal pinch bolt to (26-44 lbs. in.).



6. Remove Tool J-37089.



7. Install foreign object deflector.



8. Place Tool J-37089 on harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.



9. Install balancer on crankshaft.



10. Apply thread sealer GM #(NNN) NNN-NNNNor equivalent to threads of crankshaft balancer bolt. Torque bolt to + 56 degrees (104 lb. ft. + 56 degrees).



11. Install inner fender shield.



12. Install tire and wheel assembly. Torque lug nuts to (104 lb. ft.).



13. Lower vehicle.



14. Install serpentine belt.

Get the correct firing order of the car and re-set the firing order. Put the timing mark on the harmonic balancer on the 10 degrees before top dead centre mark check where the cam actuator is . The point should be just open of the point of the cam pacing the block

your crankshaft pulley aka Main pulley is bolted on to a harmonic balancer and the balancer sits on the crankshaft get a timing gun and figure out where the mark is on the harmonic balancer and there should be a metal plate somewhere on the timing chain cover with a mark to make the that when the number 1 piston is all the way up the marks are aligned or your timing is off

order is 18436572 cylinders are 1357 on drivers side and 2468 on passenger side, front to back. Rotor points to #1 on cap or 180 degrees off (pointing to firewall) when timing mark on front harmonic balancer is aligned with "0" on timing scale.

Back firing is caused by improper firing order or bad timing belt or chain.Verify spark plug wires are on in correct order. If no one has been changing wires, check that when harmonic balancer is lined up at top dead center that rotor in distributor is lined up to tower that goes to plug wire that goes to number one cylinder. First plug in front on passenger side. If it is off your chain or belt depending on motor needs to be changed.

I got stuck paying dealer for new crank pulley not harmonic balancer as mechanic said. I am driving as little as possible until part comes in and can br put on. Hopefully, I will not damage the crank shaft or throw a belt.

bolt torque speces for 1995 F-250 7.5L camshaft sprocket bolt,harmonic balancer bolt,timing cover bolts and water pump bolts?

you def will not be able to drive the vehicle with no balancer due to the fact that is the main source that runs all your belts...all you should need is a harmonic balancer pulley remover..
