wheel puller. Pry out seal.
Installation
1. Apply light oil coat to seal lip. Using a hammer and seal installer, tap seal into oil pump body until it is
flush with edge of pump body. DO NOT bottom seal in pump body. Align keyway slots, and install
crankshaft sprocket and Woodruff key with tapered side toward oil pump body. Install crankshaft
sprocket bolt.
2. Using Crankshaft Lock Tool (49-D011-102), lock crankshaft sprocket into position. Tighten lock bolt to
specification. See TORQUE SPECIFICATIONS
.
3. Install timing belt. See TIMING BELT
under REMOVAL & INSTALLATION. Install timing belt
covers, pulleys and drive belts. Reconnect negative battery cable and ensure timing is correct.
TIMING BELT
Removal (Miata)
1. Disconnect negative battery cable. Drain cooling system. Remove radiator hose and by-pass hoses from
thermostat housing. Remove air cleaner intake duct assembly from between throttle body and air cleaner
filter housing.
2. Remove drive belts and water pump pulley. Align crankshaft pulley timing mark with cylinder No. 1 at
TDC of compression stroke. Hold crankshaft pulley stationary. Remove crankshaft pulley bolts and
pulley. Remove crankshaft pulley hub bolt and hub.
3. Remove cylinder head cover. Remove upper, center and lower timing belt cover. If timing belt is to be
reused, mark timing belt rotation direction. Ensure timing marks on camshaft sprockets are aligned. See
Fig. 8
. Loosen timing belt tensioner lock bolt, and move tensioner away from belt with spring fully
expanded. Remove timing belt.
Removal (Protege)
1. Disconnect negative battery cable. Raise and support vehicle. Remove right front wheel. Remove right
side cover and undercover.
2. Remove drive belts and water pump pulley. Align crankshaft pulley timing mark with cylinder No. 1 at
TDC of compression stroke. Hold crankshaft stationary. Remove crankshaft pulley bolts and pulley.
Remove crankshaft pulley hub bolt and hub.
3. Remove cylinder head cover. Remove upper, center and lower timing belt cover. If timing belt is to be
reused, mark timing belt rotation direction. Ensure timing marks on camshaft sprockets are aligned. See
Fig. 8
. Loosen timing belt tensioner lock bolt, and move tensioner away from belt with spring fully
expanded. Remove timin
g belt. NOTE: For 1997-98 vehicles, the manufacturer recommends the belt be replaced at
60,000 mile intervals for vehicles sold outside of California and Massachusetts.
For vehicles sold in California and Massachusetts, inspect timing belt at 60,000
and 90,000 miles, and replace timing belt at 105,000 miles.

1. Drain engine coolant. Disconnect battery cable. Position No. 1 cylinder at TDC of compression stroke.
On Protege, remove right side cover and undercover.
2. On Miata, remove air cleaner intake duct from between throttle body and air cleaner/filter assembly. On
all models, remove upper radiator hose and by-pass hoses from thermostat housing.
3. Remove drive belts and water pump pulley. Remove power steering pump with hoses attached and secure
pump away from engine (if necessary). Remove timing belt, tensioner and idler. See TIMING BELT.
4. Unbolt water inlet pipe from water pump. Water pump inlet pipe has lower radiator hose and by-pass pipe
attached to it. Remove bolts from water pump. To install, reverse removal procedure. Tighten bolt to
specification. See TORQUE SPECIFICATIONS
.
OIL PAN
Removal & Installation (Miata)
1. Disconnect negative battery cable. Drain engine oil. Remove dipstick, tube and "O" ring. Raise vehicle on
hoist. Remove engine undercover. Disconnect steering column shaft at steering rack coupling. See Fig.
14 . Remove engine mount nuts. Lift and support engine using jack.
2. Support crossmember using transmission jack and remove crossmember bolts. Slowly and carefully lower
crossmember until clearance between oil pan and steering rack is about 4 inches. Remove oil pan bolts
from engine block and transmission.
3. DO NOT damage sealant contact surfaces. Remove oil pan by prying between oil pan and transmission
support. Remove oil pan baffle by prying it from engine. See Fig. 14
. DO NOT deform oil pan baffle.
Replace oil pan baffle if deformed. Clean sealant from oil pan, bolts, engine block and both sides of oil
pan baffle.
4. To install, apply oil resistant sealant to engine block and oil pan. Install oil pan baffle and oil pan within 5
minutes of applying sealant. To complete installation, reverse removal procedure. Tighten bolts to
specification. See TORQUE SPECIFICATIONS
. Fill engine with oil to specification. See ENGINE
LUBRICATION SYSTEM under ENGINE OILING. NOTE: For further information on cooling systems, see SPECIFICATIONS & ELECTRIC
COOLING FANS article in ENGINE COOLING.
NOTE: On Miata, engine must be supported in order to remove oil pan.
