SOURCE: front crankshaft seal, 1989 hilux

Hello,

Yes, it's possible to change the seal after removing the balancer.
If the balancer shows signs of scratching, wear at the place of the seal, change that part too!

To remove the old seal, drill 2 small opposite holes in the seal flange ( there is metal in it ).
Screw 2 (parker) screws in the holes, so you can pull the seal out gently.
Grease the new seals' inner race, and put some sealant paste to the external race.
Push it back in place with a wooden piece ( drill a hole in the center for the crankshaft end )
Grease the outher race of the balancer. This will help the seal come gently into place.

Good luck!

How can I remove the crankshaft from the engine block in order to replace the rear seal?

if you were to remove the crankshaft from the engine you would pretty much be doing a complete overhaul. most rear seals are replaced without even dropping the oil pan. you will need to remove the transmission and flywheel for a standard or flexplate for an automatic and the seal should be right in front of you

Rear barring an seal replaced

I'm not sure if this is the right part of your car but, are you talking about the rear seal on the engine for the crankshaft?

If so:

Rear Main Oil Seal REMOVAL & INSTALLATION Fig. 1: Rear main seal installation for the 2.3L and 2.5L engines 85553306.gif
Fig. 2: Removing the rear main seal 85553307.gif
Fig. 3: Installing the rear main seal on the 2.9L engines 85553308.gif
If the crankshaft rear oil seal replacement is the only operation being performed, it can be done in the vehicle as detailed in the following procedure. If the oil seal is being replaced in conjunction with a rear main bearing replacement, the engine must be removed from the vehicle and installed on a work stand.
  1. Remove the starter.
  2. Remove the transmission from the vehicle, following the procedures in Section 7.
  3. On a manual shift transmission, remove the pressure plate and cover assembly and the clutch disc following the procedure in Section 7.
  4. Remove the flywheel attaching bolts and remove the flywheel and engine rear cover plate.
  5. Use an awl to punch two holes in the crankshaft rear oil seal. Punch the holes on opposite sides of the crankshaft and just above the bearing cap to cylinder block split line. Install a sheet metal screw in each hole. Use two large screwdrivers or small pry bars and pry against both screws at the same time to remove the crankshaft rear oil seal. It may be necessary to place small blocks of wood against the cylinder block to provide a fulcrum point for the pry bars. Use caution throughout this procedure to avoid scratching or otherwise damaging the crankshaft oil seal surface. To install:
  6. Clean the oil seal recess in the cylinder block and main bearing cap.
  7. Clean, inspect and polish the rear oil seal rubbing surface on the crankshaft. Coat a new oil seal and the crankshaft with a light film of engine oil. Start the seal in the recess with the seal lip facing forward and install it with a seal driver. Keep the tool, T82L-6701-A (4-cyl. engines) or T72C-6165 (6-cyl. engine) straight with the centerline of the crankshaft and install the seal until the tool contacts the cylinder block surface. Remove the tool and inspect the seal to be sure it was not damaged during installation.
  8. Install the engine rear cover plate. Position the flywheel on the crankshaft flange. Coat the threads of the flywheel attaching bolts with oil-resistant sealer and install the bolts. Tighten the bolts in sequence across from each other to the specifications listed in the torque chart in this section.
  9. On a manual shift transmission, install the clutch disc and the pressure plate assembly following the procedure in Section 7.
  10. Install the transmission, following the procedure in Section 7.

Bolt on crankshaft to remove clockwise or counterclockwise?

prev.gif next.gif Crankshaft Damper/Pulley counterclockwise to remove pulley:
REMOVAL & INSTALLATION
  1. Remove the drive belts from the crankshaft damper.
  2. Remove the crankshaft damper-to-crankshaft bolt. Hold the crankshaft stationary by placing a suitable tool in the ring gear teeth on the flywheel. Fig. 1: Use a breaker bar to remove the crankshaft damper bolt 89613g41.gif
    Fig. 2: The crankshaft can be held stationary by using a suitable tool to place between the flywheel teeth 89613g42.gif
    Fig. 3: Be sure to lubricate the threads of the crankshaft damper bolt to obtain a proper torque reading 89613pi9.jpg

  3. Remove the crankshaft damper from the crankshaft by pulling it straight off the shaft. A puller may be required to remove the damper from the shaft. Be careful not to lose the woodruff key when removing the crankshaft damper. Fig. 4: The crankshaft damper can sometimes be pulled from the shaft by hand 89613pj1.jpg
    Fig. 5: A puller may be required to remove the crankshaft damper 89613g40.gif
    NOTE: If working on a VE30DE or VQ30DE engine, it would be a good idea to replace the crankshaft oil seal when the crankshaft damper is removed. Fig. 6: The timing chain cover oil seal should be replaced whenever the crankshaft damper is removed; this seal is leaking severely 89613pj2.jpg
    Fig. 7: This crankshaft damper may have a problem sealing properly due to the groove that was worn into it from the seal 89613pj4.jpg
    To install:
  4. Install the crankshaft damper onto the shaft, making sure the woodruff key is in place. Dip the damper bolt in fresh oil and torque the crankshaft damper-to-crankshaft bolt to the following specifications:
    • VG30E engine — 90–98 ft.lbs. (123–132 Nm.)
    • VE30DE engine — 123–130 ft.lbs. (167–177 Nm.)
    • VQ30DE engine — 29–36 ft.lbs. (39–49 Nm.) followed by 60–66°clockwise angle torque
  5. Install the drive belts to the crankshaft damper; be sure to properly set belt tension.
