OPERATING MANUAL & PARTS LIST FOR 791-5070
INSPECTION
Visual inspection should be made before each use of the
engine stand, checking for damaged, loose or missing parts.
Each stand must be inspected by a manufacturer's repair
facility immediately, if accidentally subjected to an abnormal
load or shock. Any stand which appears to be damaged in
any way, found to be badly worn, or operates abnormally
MUST BE REMOVED FROM SERVICE until necessary
repairs are made by a manufacturer's authorized repair
facility. It is recommended that an annual inspection of the
stand be made by a manufacturer's authorized repair facility
and that any defective parts, decals or warning labels be
replaced with manufacturer's specified parts. A list of
authorized repair facilities is available from the manufacturer.
ASSEMBLY INSTRUCTIONS
Assemble as shown in the diagram. First, install the casters to
the front and rear axles using the hardware items 1, 2 & 4,

Then attach the center beam assembly to the axle assembly
using hardware items 5, 11 & 12. Next, attach one end of

OPERATING INSTRUCTIONS
NOTE: Do not mount engine to mounting plate
unless all three pins, item 8, are in place and
secured with latches provided according to
Assembly Instructions.
Drain oil and coolant and remove flywheel from engine
before mounting. Mount engine as directed in procedures
which follow. Refer to engine service manuals and technical
bulletins when mounting engines. Lift engine (block) with
crane or hoist until even with head of engine stand. Bolt
through adjustable fingers to back of block at bell housing
mounting holes. Fasten securely to mounting plate. Slowly
lower crane or hoist so that the engine stand supports full
weight of engine. To check engine balance, carefully loosen
hex bolt at back of rotating head, making sure stand is
secured from tipping, and turn handle to rotate engine. If
balance is not satisfactory, rotate engine to its original
position and raise with crane or hoist just enough to take
weight off the stand. Loosen bolts on adjustable fingers and
realign so that weight is evenly distributed. Tighten all bolts
securely and recheck balance. To remove an engine from
stand, attach a crane or hoist and raise engine just enough
to take engine weight off stand. Carefully remove bolts
attaching fingers to engine. Be aware that there will be
a slight movement of stand as total engine weight is
transferred to crane.
The engine may be rotated by turning the worm crank.
Grease before each use. The stand can be folded down for
easy storage and transportation by removing 3 pins, item 8.
