Crankcase (Oil Pan) Mounting
1. Install the universal bracket to the crankcase using the existing crankcase bolts (Figure 4A). Crankcase bolt
diameter must be no larger than 7/16 inch (11 mm).
2. Mount the LM2000 to the universal bracket using two 1/4-20 UNC x 1- 1/4 inch bolts, nuts and lock washers
supplied. DO NOT tighten the adjustment bolts too tight. You will have to adjust the LM2000 later in the instal-
lation process.
3. If space between the crankcase and mounting bracket is narrow, install the universal mounting bracket to the
LM2000 before installing to the crankcase oil pan.
Connecting Fittings and Hoses
The following instructions are based on the Murphy optional hose kit described on page 1. If you did not
order the optional hose kit, use the list designation as a guide to the required materials.
1. Install the LM2000 fittings in their proper locations.
2. Attach the 1 inch (25 mm) diameter, flexible monitoring hose to the
crankcase and the monitoring port on the LM2000. See Figure 5.
3. Install the 1/2 inch (13 mm) I.D. x 3 ft. (914 mm) hose to the vent connection on the LM2000 and to the vent
connection on the crankcase. See Figure 5. The vent connection on the crankcase must be well above the
regulated oil level. All hoses must be clear of obstructions, valleys, or dips that could create liquid traps, or
gas/air pockets. The vent and crankcase connections should be as straight as possible.
NOTE:
Check clearance between crankcase and mounting bracket before installing
the mounting bracket. If space between the crankcase and mounting bracket does not
allow installation and access to the adjustment bolts advance to Step 3.
NOTE:
Apply a sealant such as Teflon®, to all
threaded connections.
CAUTION: The hose must slope slightly
downward from the LM2000 and MUST NOT
have any droops or low spots.
NOTE:
If the drain plug on the crankcase is
used for the connection, we recommend instal-
lation of a tee to allow draining of the crank-
case for service.
