Use an injector sleeve expander, Part No. ST-880, to

expand the upper section of the injector sleeve.

Adjust the expander roller edge (1) and the collar (2) to the

clearance specified.

Clearance: 40 mm [1.6 inches]

The rollers on the sleeve expander must extend 13 mm

to 15 mm [0.5-inch to 0.6-inch] below the top of the in-

jector sleeve. Do not extend the rollers more than 15 mm

[0.6-inch] below the top of the sleeve.

Install the expander in the injector sleeve, and turn the

mandrel with an inch pound torque wrench.

Torque Value: 8 N•m [75 in-lb]

Remove the expander and the holding tool from the in-

jector sleeve.

Use a pilot, Part No. ST-884-6; a holder, Part No. ST-

884-1; and an injector seat cutter, Part No. ST-884-3, to

cut the injector seat.

Install the injector sleeve cutter and the cylinder head in

a drill press.

Use a generous amount of cutting oil to lubricate the

cutter head during the machining operation to prevent

galling of the injector sleeve.

Carefully machine the injector sleeve until the sealing

area is smooth. Remove only the minimum amount of

copper to obtain a smooth sealing area.

Clean the metal particles from the injector sleeve bore.
