B.1.b. Crossflow Cylinder Lifter Removal
NOTE: Remove only those components related to the “Intake”
valve train unless exhaust lifter inspection is required as indicated
in Step 2, paragraph 1.
Procedure
1. Remove cowling and any airframe supplied accessories according to the airframe
manufacturer's instructions to gain access to the cylinder.
2. Disconnect the battery according to the airframe manufacturer's instructions.
3. Disconnect all spark plug leads and remove the upper spark plug from each cylinder.
4. Remove the rocker cover fasteners and rocker covers from the cylinder.
5. Remove and discard the rocker cover gaskets.
6. Position the crankshaft so the piston is at top dead center and both intake and exhaust
valves of the cylinder being disassembled are closed.
7. Remove the rocker shaft retention screw (nuts for 240/360), tab washer and retainer
from the rocker arm bosses; discard the tab washers.
8. Bleed the hydraulic lifters down by applying steady pressure to the pushrod end of the
rocker arm; lifter pressure relief should be obvious.
9. Remove the rocker shafts, rocker arms, and thrust washers from the cylinders.
10. Withdraw all of the push rods from their respective housings. Mark the location and
position of removal to ensure installation in the same position and location.
11. Compress each push rod housing spring with a Pushrod Spring Compressor Tool.
While the spring is compressed, push the outboard end of the pushrod housing away
from the cylinder head, lower the outboard end of the pushrod housing down and
away from the cylinder. Remove the push rod housing, springs, washers, O-ring, and
packing.
12. Discard the O-ring and packing.
13. Remove the hydraulic lifters from the crankcase lifter bores. Identify the location and
position from which the lifters are removed. Serviceable lifters shall be returned (as
applicable) to the same cylinder position and location from which they were
removed.
14. If the lifter cannot be removed easily from the lifter bore, do not force removal;
contact TCM for further instructions.
