Toyota Cressida, Corona, Crown, Mark II Repair Manual 1970-1982

CAMSHAFT AND BEARINGS

REMOVAL AND INSTALLATION

1. Perform the Cylinder Head Removal procedure (for your engine) far enough to gain access to the camshaft bearing cap bolts. If you are going to remove the head anyway, remove the cam after removing the cylinder head.



2. Prior to removing the camshaft, measure its end-play with a feeler gauge. The end-play limit is 0.0098 inch (0.248mm) for the 8R-C, 18R-C, 20R and 22R engines; 0.01 inch (0.254mm) for the 4M-E and 5M-E engines.
   
   If the end-play is beyond this, replace the head.



3. Use a 12mm wrench to remove the bearing cap bolts. Remove the caps. Keep them in order, or mark them.



4. Measure the bearing oil clearance by placing a piece of Plastigage on each journal. Replace the caps and tighten their bolts to 13-16 ft. lbs. (17-22 Nm).



5. Remove the caps and measure each piece of Plastigage. If the clearance is greater than 0.004 inch (0.101mm), replace the head and cam.



6. Lift the camshaft out of the head.


TO INSTALL


7. Coat all of the camshaft bearing journals with engine oil.



8. Lay the camshaft in the head.



9. Install the bearing caps in numerical order with their arrows pointing forward (toward the front of the engine).



10. Install the cap bolts and tighten them to 13-16 ft. lbs. (17-21 Nm).



11. Complete the cylinder head installation procedure as previously outlined.

WHEEL ASSEMBLY

REMOVAL AND INSTALLATION (See Figure 1)

1. Apply the parking brake and block the opposite wheel.



2. If equipped with an automatic transmission, place the selector lever in P; with a manual transmission, place the shifter in Reverse.



3. If equipped, remove the wheel cover or hub cap.



4. Break loose the lug nuts. If a nut is stuck, never use heat to loosen it or damage to the wheel and bearings may occur.
   
   If the nuts are seized, one or two heavy hammer blows directly on the end of the bolt head usually loosens the rust.
   
   Be careful as continued pounding will likely damage the brake drum or rotor.



5. Raise the vehicle until the tire is clear of the ground. Support the vehicle safely using jackstands.



6. Remove the lug nuts, and then remove the tire and wheel assembly.


TO INSTALL


7. Make sure the wheel and hub mating surfaces, as well as the wheel lug studs, are clean and free of all foreign material. Always remove rust from the wheel mounting surfaces and the brake rotors/drums. Failure to do so may cause the lug nuts to loosen in service.



8. Position the wheel on the hub or drum and hand-tighten the lug nuts. Make sure that the coned ends face inward.



9. Tighten all the lug nuts, in a crisscross pattern, until they are snug.
