Service Precautions Summary - Volvo EPA2007 D13F Reference Manual

Service Precautions Summary

Following is a summary list of the DO and Don't issues applying to D13F engine
service:
1 DO NOT machine the cylinder head for clean-up since this will change injector
depth, thereby affecting emission. It will also upset the ability to correctly adjust
timing gear backlash.
2 DO NOT grind the injector copper sleeves.
3 Connecting rods and crankshaft main bearing capscrews can be re-used four times.
Screw heads MUST be punch marked at each overhaul to indicate the number
of times used.
4 Install the crankshaft main bearing caps according to marked assembly number.
Correct alignment is also critical and is aided by the following:
•
Two casting nipples, located in the cylinder block and on the respective bearing
cap, eliminate incorrect assembly
•
Sleeve pressed into the cylinder block guide the bearing caps into position
for proper alignment
5 Connecting rod caps MUST BE mated to their respective connecting rods due to
the "fractured manufacturing" process used. Also, the rod caps can be installed
only one way because of the difference in spacing between screw holes at each
side of the cap.
6 DO NOT use the lifting eye on the flywheel housing when tilting the engine /
transmission assembly to an angle greater than 15 degrees.
7 Cylinder head installation requires lowering the head onto the gasket, then pulling
the head horizontally against the timing gear mounting plate using through screws.
Pressed bosses in the gasket keep the head from making full contact with the
gasket surface and prevent damage to the rubber sealing rings as the head slides
into position.
8 DO NOT use starting fluid (ether) on engine equipped with an inlet manifold air
heater element. An explosion could occur.
9 The D13F engine uses a number of O-rings for sealing various fluid joints and
tubes. It is essential that new O-rings of the correct material be used whenever
joints are disassembled and reassembled.
