10.17a Temporarily tighten the tensioner after moving it to the 10.17b
Correct spring position on the tensioner
end of the slot
11.4 If the sprocket is stuck, drill and
tap two holes and remove it with a
bolt-type puller
11.7 Apply a film of grease to the lips of
the new seal before installing it (if you
apply a small amount of grease to the outer
edge, it will be easier to push into the bore

amount of tension to the belt..
22 Slowlyturn thecrankshaftclockwisetwo full revolutions, returning the
numberone piston to TDC on the compression stroke. Caution: Ifexces-
sive resistance is felt wile turning the crankshaft, it’s an indication that the
pistons are coming into contact with the valves. Go back over the proce-
dure to correct the situation before proceeding.
23 Check to be sure all timing marks are still aligned (see illustration
10.14). Tighten the tensioner nut or bolt to the torque listed in this Chap-
ter’s Specificatidns while keeping the tensioner steady with your hand.
24 Check the deflection of the timing belt by observing the force the ten-
sioner pulley applies to the timing belt. If the belt seems loose, replace the
tensioner spring.
25 Install the various components removed during disassembly, refer-
ring to the appropriate Sections as necessary.

1 Disconnect the negative cable from the battery.
2 Remove the drivebelts (see Chapter l), crankshaft pulley and timing
belt (see Sections 9 and 10).
3 Wedge two screwdrivers behind the crankshaft sprocket. Carefully
pry the sprocket off the crankshaft. Some timing belt sprockets can be
pried off easily with screwdrivers. Others are more difficult to remove be-
cause corrosion fuses them onto the nose of the crankshaft. If the pulley
oh your engine is difficult to pry off, don’t damage the oil pump with the
screwdrivers.
4 If the sprocket won’t come loose, drill and tap two holes into the face of
the sprocket and use a bolt-type puller to slip it off the crankshaft (see il-
lustration). Caution: Do not reuse a drilled sprocket - replace it.

6 Carefully pry the oil seal out with a screwdriver or seal removal tool.
Don’t scratch or nick the crankshaft in the process!
7 Before installation, apply a coat of multi-purpose grease to the inside
of the seal (see illustration).
8 Fabricate a seal installation tool with a short length of pipe of equal or
slightly smaller outside diameter than the seal itself. File the end of the
pipe that will bear down on the seal until it’s free of sharp edges. You’ll also
need a large washer, slightly larger in diameter than the pipe, on which
the bolt head can seat (see illustration). Install the oil seal by pressing it
into position with the seal installation tool (see illustration). When you
