A smooth file or hone may be used to remove small burrs from gear teeth, retaining ring grooves and mating
surfaces. The burrs must be very minor and if on gears only on the engaging edge of the teeth.
c. Damaged painted surfaces should be repainted as soon as possible to prevent corrosion.
ASSEMBLY. Step-by-step procedures for assembly of the bridge boat components are provided in Chapter 3. In
addition the following practices should be observed.
The housing contact surface of oil seals should be coated with a non-
hardening sealer to prevent leaks. The
lips should be coated with grease (GAA).
All pressing operations should be accomplished using a suitable press and adapters unless otherwise
Metallic parts should be lubricated with the lubricant utilized in the component during operation.
Critical torque values are specified in the assembly procedures.
Silicone rubber sealant is used on gaskets and mating surfaces in the engine assembly.
3-7. GENERAL DETAILED PROCEDURE APPLICATIONS
Resources required are not listed unless they apply to the procedure.
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.
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) being OFF.
Remember the bridge erection boat has two water cooling systems (refer to FO-3).
The MK1 engine WILL NOT be operated without a supply of water to circulate through the raw water system.
At full speed the system requires 27 gallons of water per minute. The 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).
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.
