Install Components On The Engine
Note
If the engine stand does not give sufficient access to install the shockmount assemblies on the engine,
install the shockmount assemblies on the engine when it is on the hoist before it is installed in the
airframe.
Note
If you are to install a new or overhauled
Shockmount Assy Figure 6 [23]
, use new
Bolt Figure 6 [18]
and new Washer Figure 6 [19] as applicable.
3.3.1 Apply Corrosion preventive (Pt.No. P04-039) to the shaft and under the head of the bolts Figure 6 [18].
Note
Make sure that the threads of the bolts
Figure 6 [18]
are clean and free from corrosion preventive.
3.3.2 Apply Grease (Pt.No. P04-028) to the threads of the bolts Figure 6 [18].
3.3.3 Install the shockmount brackets Figure 6 [23] and new Gasket Figure 6 [24] on the engine with the
bolts Figure 6 [18] and washers Figure 6 [19].
3.3.4 Use a straight edge Figure 6 [25] to make sure the mounts Figure 6 [23] align.
3.3.5 Torque the bolts Figure 6 [18] to between 28 and 31 Nm (248 and 270 lbf in).
3.3.6 Safety the bolts Figure 6 [18] with Lockwire (standard) (Pt.No. P02-001).
3.3.7 CAUTION
MAKE SURE THAT YOU INSTALL THE CORE ASSEMBLIES IN THE CORRECT POSITION. IF
YOU DO NOT, THE ENGINE WILL BE MISALIGNED WITH THE AIRFRAME.
Note
The core assemblies look similar but are different part numbers, and it is possible to install the front
core assembly in the rear position and vice versa. If this happens the engine is not in the correct
position on the airframe. Make sure that you install the core assembly that has a flange in the rear
position.
Install the plates Figure 6 [21], bush Figure 6 [22] and core assemblies Figure 6 [20] on the
shockmounts Figure 6 [23]. Make sure that the pins and holes align correctly.
3.3.8 Install the bracket Figure 6 [15] on the reduction gearbox Figure 6 [17] with the two bolts Figure 6 [16].
3.3.9 Install the torque transducer Figure 6 [4], refer to AMM 12-B-77-40-03-00A-920A-A.
3.3.10 Install the torque transducer Figure 6 [9], refer to AMM 12-B-22-20-05-00A-920A-A.
3.3.11 Install the clamps Figure 6 [14] on the pipes Figure 6 [3] and Figure 6 [7] as follows:
3.3.11.1 Put the lower clamps Figure 6 [14] in position 45 mm (1.77 in) above the center-line of the tee-union
Figure 6 [6] and install the screws Figure 6 [11], washers Figure 6 [13] and nuts Figure 6 [12].
3.3.11.2 Put the upper clamps Figure 6 [14] in position 35 mm (1.38 in) above the center-line of the lower
clamps Figure 6 [14] and install the screws Figure 6 [11], washers Figure 6 [13] and nuts Figure 6 [12].
3.3.12 Loosely connect the pipes Figure 6 [2], Figure 6 [3], Figure 6 [5], Figure 6 [7], Figure 6 [8] and
Figure 6 [10], unions Figure 6 [1] and Figure 6 [6] to the engine and the torque transducers
Figure 6 [4] and Figure 6 [9]. Make sure there is a clearance of not less than 3,0 mm (0.12 in)
around all the pipes and then tighten the coupling nuts.
3.4 Install The Firewire
3.4.1 Install the clamp Figure 5 [54] on the engine with the bolt Figure 5 [53].
3.4.2 Torque the bolt Figure 5 [53] to between 3,6 and 4,0 Nm (32 and 36 lbf in).
