The dimensions below are for the optional -EX model enclosure. The
standard model enclosure dimensions are the same except the height and
width which are: 7 in. (178 mm) H, 7-7/8 in. (200 mm) W.
Mounting (all LM300 Series models)
NOTE: Mount the LM300 series level maintainers as close as possible
to the crankcase. Also, excessive vibration can cause overfill. Be sure
mounting brackets are supported.
The following instructions are based on the usage of the pipe and universal
mounting brackets shown above.
Pipe Bracket Mounting
1. Mount a nominal 1/2 inch (21 mm) diameter pipe to the deck of the engine.
2. Install the pipe bracket to the LM300 using two 3/8-16 UNC x 1 inch
bolts supplied. See Figure 1A.
3. Slip the LM300 onto the pipe and install the two adjustment bolts. Each
adjustment bolt consists of a 3/8-16 UNC x 1 inch bolt and two nuts. See
Figure 1B. DO NOT tighten the adjustment screws too tightly because
you will have to adjust the LM300 later in the installation process.
Mounting with Universal Bracket
The universal bracket has two mounting methods: deck mounting and
pan mounting.
Deck Mounting
1. Install the universal bracket to the deck as shown in Figure 2A with two
flat washers and two 3/8 inch (10 mm) diameter bolts (not supplied).
2. Mount the LM300 to the universal bracket using two 3/8-16 UNC x 1
inch (25 mm) bolts supplied (Figure 2B). DO NOT tighten the
adjustment screws too tightly. You will have to adjust the LM300 later in
the installation process.
