1994 Ford Tempo GL 2.3L Harmonic Balancer Removal and Replacement
Removal
1. Disconnect the battery ground cable at the battery terminal.
2. Disconnect the battery ground strap from the starboard side of the engine near the passenger side strut tower by removing the bottom bolt of the fuel line shield.
3. Release tension on the belt tensioner and remove the drive belt.
4. Remove the fuel line shield. {If you don’t, it will prevent the engine from dropping down far enough later when you try to lower the engine to remove and reinstall the harmonic balancer. It is also nice to have this out before trying to remove the water pump pulley.}
5. Remove the belt tensioner. {It will be in the way when attempting to remove the engine side of the starboard engine mount.}
6. Mark front side of the water pump pulley and then remove the water pump pulley.
7. Check the bearings and free play of the water pump, idler pulley, and belt tensioner pulley. If any of these is worn, replace it now. You have already done the labor!
8. Raise and support the vehicle.
9. Remove bolt for accumulator-to-compressor A/C line support bracket, then position A/C line toward rear of engine compartment.
10. Installa Rotunda Engine Support Bar 014-00750 or equivalent;
Or position a bottle jack or equivalent and safety stands under the transmission and engine, use blocks of wood to protect the oil and transmission pans.
11. Remove both sides of the starboard engine mount. {Remove the second half of the mount on the engine side as well as the half on the wheel well. This means getting to the upside down 18mm nut at the firewall end of the engine mount. I have had success getting to this from underneath the car with a long extension.}
12. Remove right (starboard) side bushing bracket and mounting bracket for stabilizer.
13. Remove the vibration harmonic balancer bolt:
a. Option A) Remove the 7/8” vibration harmonic balancer bolt through the opening in the wheel well after removing the passenger side {starboard} front tire. Then lower the engine assembly taking care not to crush the fuel fittings that were protected by the fuel line shield.
b. Option B) Carefully Lower the engine assembly and then remove the 7/8” vibration harmonic balancer bolt from under the car. IF, and ONLY IF, you do not have adequate clearance under the car to remove the old or install the new vibration harmonic balancer, perform these additional steps:
i. Remove front isolator through-bolts and lower retaining nuts.
ii. Remove rear isolator through-bolts.
iii. Remove right isolator lower retaining nut, then carefully lower drivetrain.
14. Remove the vibration harmonic balancer. If necessary, use Bearing Puller T77F-4220-B or equivalent. Your vibration harmonic balancer may come off in up to three pieces, the outer sheet metal, the pulley portion including the long ago deteriorated rubber, and the metal sleeve with the key slot that slips over the end of the crankshaft. Fortunately, my metal sleeve came off with a little gentle prying; yours may require a gear puller.

Installation is NOT just the reverse of the Removal procedure!

Or you could try the flat rate method of removing the bolt, and prying (with a really big prybar) against the frame and hoping for the best. If it doesn't come off, then you can always pull the engine.
