CYLINDER HEAD REPAIR - CONTINUED
ASSEMBLY - CONTINUED
Cylinder head repair conditions may warrant cylinder head pressure testing before complete head
assembly. Testing should be performed before intake and exhaust valve components are installed.
Ensure all cup plugs, pipe plugs, and injector tubes are installed before pressure testing cylinder head.
Refer to inspection steps 2 through 10 for testing.
Using 12-point (23-mm) socket and speed handle, turn injector tube reconditioning set tip refinisher to remove excess
stock, so that lower end of injector tube (64) is from flush to 0.008 in (0.20 mm) (73) below fire deck surface of cylinder
head. Remove chips from injector tube.
Position cylinder head (2) fire deck side down.
Insert chamfered end of new valve guide (14) into cylinder head (2) with seal groove up.
Insert driver (74) into valve guide installer (75). Install assembly over valve guide (14). Drive valve guide into cylinder
head (2) with air chisel (23) until driver bottoms.
Check protrusion of valve guide (14) from cylinder head (2). Height should be 1.486 in (37.75 mm).
