Read and understand these instructions BEFORE attempting to install this
product. See reference to diagrams on back page.

1. All Tru-Time Cam Gears for Mitsubishi have provisions for the cam angle sensor that is

mounted behind the intake cam gear on the 1995 to 1996 Mitsubishi Eclipse. The models
starting with the 1997 model year have the cam angle sensor mounted at the rear of the
cylinder head.

2. The procedure to change the gears is identical to the timing belt replacement procedure

outlined in the factory service manual.

3. Obtain a suitable box or container to hold the hardware that will be removed from the

engine during this installation. This will aid in the prevention of lost nuts and bolts.

4. Disconnect the negative battery terminal before starting these procedures.

5. Removal of cam cover

(a) Remove the top center cover.

i) Clean the area underneath the center cover. This is to

ensure that you do not allow any debris to contaminate
the engine internals.

(b) Remove the spark plug wires from the spark plugs but do

not remove the spark plugs at this time. Set the spark plug
wires away from the area of work.

i) The removal of the spark plugs will make it easier to

rotate the engine by hand. Care
should be taken not to allow any
small items to fall into the open
spark plug holes while you
continue to install the cam gears.
Lay a rag over the open spark
plug holes.

6. Removal of timing belt front covers

(a) Raise the front of the vehicle and

support it using properly rated jack
stands. It is important for safety
reasons to use adequate supporting
equipment to prevent injury or
damage to the vehicle.

(d) From the engine compartment, remove all drive belts (a/c, alternator/power steering

belts), and the water pump pulley set.

a/c idler pulley, and remove the front center cover.
