Do not let hydraulic lifters fall out as the camshaft carrier is
removed.
Hydraulic lifters should be stored in an upright position.
Used hydraulic lifters
must be replaced into original lifter
bores.
Camshafts and lifters, installing
(M52 Engine)
Lubricate camshafts, camshaft carriers, bearing caps, hy-
draulic liflers, friction washers, splined shafts and spline hubs
with assembly lubricant before installation.
Make sure
the cranltshaft, which had been rotated approxi-
mately
30" opposite the direction of engine rotation from
TDC, is still in thatposition before lowering the
camshaffs into
position. All pistons must be out of TDC position to prevent
valve/piston interference when the camshalts are installed.
Before installing camshaft carriers, examine bearing bores
(arrows) on hydraulic lifter bores for signs of wear.

NOTE-
The camshaft bearing caps are coded with a letter and a
number. For example, "A
1" is the first exhaust camshaft
bearing cap
at the front of the engine, and "El "is the intake
camshaft bearing cap at the front of the engine.
-. -
The camshafts are stamped with a code letter - "E for the
intake side and
'X" for the exhaust side.
"E is for Einlap. (German for intake) and 'XA7s for Auspuff.
(German for exhaust).
- Repeat procedure for exhaust camshaft

I CAUTION-
Used liydraulic lifters must be reinstalled in original lifter
1 bores.
4 Remove lower camshaft bearing carriers from cylinder head.
CAUTION- Camshaft bearing carriers must be reinstalled in their original
locations
(E for intalce and A for exhaust).
NOTE- Do not allow hydraulic lifters to fall out of camshaft carriers.
Hydraulic lifters should be stored in an upright position.
Camshafts and lifters, installing (M52TU and M54 engine)
Lubricate camshafts, camshaft carriers, bearing caps, hy-
draulic lifters, friction washers, splined shafts and
spline hubs
with assembly
lubricant before installation.
CAUTION-
Make sure the crankshaft, which had been rotated approxi-
mately
30" opposite the direction of engine rotation from
TDC, is
stillin thatposition before lowering the camshafts into
position. Allpistons must be out of
TDCposition to prevent
valve/piston inteiference when the carnshafis are installed.
- Lift timing chain and place exhaust cam onto exhaust cam-
shaft carriers. Place
intake camshaft on camshaft carrier.
