ASSEMBLY. Step-by-step procedures for assembly of the bridge boat components are provided in Chapters 2 and 3. In
addition observe the following practices:
a. Coat the housing contact surface of oil seals with a non-hardening sealer to prevent damage. The lips should be
coated with grease (GA).
b. All pressing operations should be accomplished using a suitable press and adapters unless otherwise specified.
c. Metallic parts should be lubricated with the lubricant utilized in the component during operation.
d. Critical torque values are specified in the assembly procedures.
e. Silicone sealant is used on gaskets and mating surfaces in the engine assembly.
GENERAL DETAILED PROCEDURE APPLICATIONS
a. Resources required are not listed unless they apply to the procedure.
b. Personnel required are listed only if the task requires more than one. If PERSONNEL are not listed it means that
one person can do the task.
c. The normal standard equipment condition to start a maintenance task is power (MASTER SWITCH) OFF.
EQUIPMENT CONDITION is not listed unless some other condition is required besides the (MASTER SWITCH)
When the MK-1 and MK-2 boat engines are operated out of the water, the temperature gages must
be monitored at all times to prevent overheating and engine damage.
Remember the bridge erection boat has two water cooling systems (refer to FO-1).
The MK1 and MK2 engine WILL NOT be operated out of water for more than 20 minutes at idle speed. Any
maintenance task step that requires engine operation MUST BE performed with the boat in water or by following
Out of Water Engine Operation procedures (TM 5-1940-277-20).
e. Standard maintenance procedure requires that upon completion of a maintenance action a component function
and performance check be conducted to assure no leakage or malfunction exists. If leakage or malfunction is
found repeat the maintenance procedure to correct problem.
f. Standard maintenance procedure requires that an operational check be performed after completion of repairs if
possible. This step is not called out as part of the procedure.
