1106 Perkins engine - Fuel Injection Lines (Remove and install)
Removal procedure
Isolate the fuel supply. Isolate the electrical supply. Remove the two
plastic clamps (2) from the fuel injection lines (1). Discard the
plastic clamps. Slide the dust seal (3) from the nut on the fuel
injection line (1). Disconnect the fuel injection line (1) at the
electronic unit injector (4). Disconnect the fuel injection line (1) at
the fuel manifold (5).
Remove the fuel injection line (1). Discard the fuel injection line.
Clean up any spillage of fuel immediately. Plug the open port in the
fuel manifold (5) immediately. Use Tooling in order to plug the open
port in the fuel manifold. Remove the seal (6) from the electronic unit
injector (4) and the base of the valve mechanism cover (not shown). The
seal can be damaged by contact with fuel.
Plug the open port in electronic unit injector (4) immediately. Use
Tooling in order to plug the open port in the electronic unit injector.
Repeat Steps in order to remove the remaining fuel injection lines from
the fuel manifold to the electronic unit injectors.
Disconnect the harness assembly (9) from the fuel injection pump (8).
Slide the locking tab (10) into the unlocked position. Disconnect the
harness assembly (9) from the position sensor (11). Position the harness
assembly (9) so that the harness assembly is clear of the fuel injection
line (7).
Assembly of the tube clip
Remove the fasteners (12) from the three tube clips (13) that secure the
fuel injection line (7). Loosen the three allen head screws (14).
Position the tube clips in order to allow removal of the fuel injection
line. Disconnect the fuel injection line (7) at the fuel injection pump
(8). Disconnect the fuel injection line (7) at the fuel manifold (5).
Plug all open ports immediately. Use Tooling in order to plug the open
ports in the fuel manifold (5) and in the fuel injection pump (8).
Remove the fuel injection line (7). Clean up any spillage of fuel
immediately. Remove the allen head screws (14) and the assemblies of the
three tube clips (13) from fuel injection line (7). Discard the fuel
injection line.
Installation procedure
The following procedure should be adopted in order to install the fuel
injection lines when the electronic unit injectors or the fuel manifold
have not been removed.
Assembly of the tube clip
Loosely install the assemblies of the three tube clips (13) and the
allen head screws (14) to the fuel injection line (7). Place the fuel
injection line (7) in position. Remove the caps from the port in the
fuel injection pump (8) and from the appropriate port in the fuel
manifold (5). Remove the caps from the new fuel injection line (7).
Loosely connect the nuts at both ends of the fuel injection line (7), to
the fuel manifold (5) and to the fuel injection pump (8). Ensure that
the ends of the fuel injection line are correctly seated in the fuel
injection pump and in the fuel manifold. Use Tooling to tighten the nuts
on the fuel injection line (7) to a torque of 30 Nm (22 lb ft).
Install the setscrews (12) for the three tube clips (13) that secure the
fuel injection line (7). Tighten the setscrews (12) to a torque of 22
N·m (16 lb ft). Tighten the M5 allen head screws (14) to a torque of 10
Nm (89 lb in). Ensure that fuel injection line does not contact any
other engine component.
Connect the harness assembly (9) to the position sensor (11). Slide the
locking tab (10) into the locked position. Connect the harness assembly
(9) to the fuel injection pump (8).
Thoroughly clean the seal (6). Inspect the seal for damage. If
necessary, replace the seal. The seal can be damaged by contact with
fuel. If the seal has been in contact with fuel for a prolonged period,
the seal should be replaced. Install the seal (6) to the electronic unit
injector (4). Ensure that the flange on the seal is flush with the valve
mechanism cover base.
Remove the caps from the new fuel injection line (1). Ensure that a new
dust seal (3) is installed to the fuel injection line. Remove the caps
from the electronic unit injector (4) and from the appropriate port in
the fuel manifold (5). Loosely connect the nuts at both ends of the fuel
injection line (1), to the electronic unit injector (4) and to the
appropriate port in the fuel manifold (5).
Ensure that the ends of the fuel injection line are correctly seated in
the electronic unit injector and in the fuel manifold. Use Tooling to
tighten the nuts on the fuel injection line (1) to a torque of 30 Nm (22
lb ft). Slide the dust seal (3) into position over the nut on the fuel
injection line. Ensure that the dust seal (3) is in contact with the
seal (6).
Follow Steps in order to install the remaining fuel injection lines.
Install two new clamps (2) to the fuel injection lines. Ensure that the
clamps are fully closed in order to retain the fuel injection lines.
Ensure that fuel injection lines do not contact any other engine
component. Restore the fuel supply. Restore the electrical supply.
Remove the air from the fuel system.
