.0010 - .0022 in or .025 - .055 mm
max limit is .0031 in or .08 mm
To set the tappets on a Toyota 2E engine, first ensure the engine is cold. Remove the valve cover and use a feeler gauge to measure the clearance between the tappet and the rocker arm. The intake valve clearance should be set to 0.15 mm, while the exhaust valve clearance should be set to 0.20 mm. Adjust the clearance by loosening the lock nut and turning the adjusting screw until the correct clearance is achieved, then recheck and secure the lock nut.
I believe the clearance should be within .002 and .007 thousands of an inch. and also the end play clearance, should be between .002 and .007. you should check the bearing caps with plastic gauge, and the end play wiyh a feeler gauge.
The 1989 Toyota rod bearing torque specification is 150 pounds. You should torque the rod bearings bolt in 50 pound intervals.
When rod bearing clearance is too tight the end result is what is called a spun bearing -- definitely a bad thing. Bearing clearance is the difference between the inside diameter of the bearing and the outside diameter of the crankshaft journal to which it is clamped. The bearing is supplied pressurized oil fed by the oil pump, it should never touch the crankshaft journal but should always float on a wedge of oil. If the clearance is too tight the bearing touches or drags on the crankshaft journal and the journal grabs the bearing and spins it inside the housing into which it is clamped -- which in the case of a rod bearing is the big end of the connecting rod. Once this happens it all pretty much self destructs as it chews up the big end of the connecting rod and the crankshaft journal as well.
The tapet clearance, or valve clearance, for the C223 engine typically ranges from 0.20 to 0.25 mm (0.008 to 0.010 inches) for both intake and exhaust valves. It's important to check the manufacturer's specifications for your specific engine model, as there may be slight variations. Proper adjustment of the tapet clearance is crucial for optimal engine performance and to prevent valve train noise. Regular maintenance should include checking and adjusting the clearance as needed.
yes i should buy
valve clearance should be pusted under tune up spec under "stock hood" sticker should be on the left hand side
Intake= .010" Exhaust=.020" This should be done on a cold engine.
That is the kind of thing that you should check in the engine re-build section of that car's manual.That is the kind of thing that you should check in the engine re-build section of that car's manual.
Normall it will last the life of the engine and is changed when the engine is overhauled.
Main caps should be torqued at 76 foot pounds for the 22r.
