SETUP INSTRUCTIONS
This is the safety alert symbol used for the SETUP INSTRUCTIONS section of this manual to alert you to potential personal injury
hazards. Obey all instructions to avoid possible injury or death.
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. First, install the casters (5 & 16) to the front and rear axles (2 & 18) using the hardware items (3, 4 & 6), being sure to insert bolts from the
bottom side of caster plate. IMPORTANT: All hardware that assembles items (2, 9, 18, 19 & 27) together should be assembled
loose to ensure all bolts fit through their designated holes.
2. Attach the center beam assembly (9) to the axle assemblies (2 & 18) using hardware items (1, 10, 11 & 17).
3. Next, attach one end of brace (19) to the center beam using hardware items (1, 10, & 11). Make sure position of brace is as shown in
diagram.
4. PIace post (27) with gear box assembly onto base assembly as follows: Stand the post on the base and attach by passing bolt (1) through
middle hole in the base bracket and the hex shaped mount welded to the bottom of the post. Then pass pin (7) through the upper hole
in the base bracket and just in front of the post. Secure pin with clip (8) provided. Now, insert pin (7) through the rear hole, including both
brackets and secure with clip (8) provided.
5. Attach the end of the brace (19) to the post using pin and clip (7 & 8).
6. Now tighten all hardware that assembles items (2, 9, 18, 19 & 27) together.
7. Rotate the worm box (29) so its three holes line up with the holes in the post (27) and secure them with the hardware (25 & 26) provided.
The worm box (29) should be positioned as shown in the diagram.
8. To fold engine stand, simply remove the three pins and clips, fold brace forward, and then fold post forward. The pins and clips can be
stored in open holes.
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
NOTE: Do not mount engine to mounting plate unless all three pins (7) are in place and secured with clips (8) provided according to the
ASSEMBLY INSTRUCTIONS.
1. Consult the vehicle or engine manufacturer for service manuals and/or technical bulletins that provide information on suggested engine
mounting tips, proper size and type mounting bolts and the engine's center of balance. The engine's center of balance will have to be
aligned with the rotational axis of the engine stand's mounting head assembly.
2. Drain oil and coolant and remove clutch bell housing and flywheel from engine before mounting. Attach an engine lifting bar or sling to
the engine and secure the bar or sling to a shop crane or hoist. Slowly lift the engine from its compartment making sure no other vehicle
components, wires or hoses obstruct the free movement of the engine. Raise the engine high enough so its center of balance is close to
the rotational axis of the stand's mounting head.
3. Make sure, the four mounting head fingers are loosely connected to the mounting head plate. Secure the four mounting head fingers to the
bell housing end of the engine with the appropriate bolts and washers. Reposition the mounting head, fingers and engine so the engine's
center of balance is within one inch of the mounting head's rotational axis. Tighten all bolts to a sufficient torque requirement that prevents
any slippage.
4. Slowly lower the crane or hoist so the engine stand supports full weight of the engine. To check engine balance and secure setup of the
engine to the stand, slowly rotate the engine by turning the gear crank handle. If balance or setup are not stable, rotate the engine to its
original position, raise the crane or hoist so the weight of the engine is removed from the stand and make the correct adjustments. After
adjustments are made, tighten all bolts. This adjustment procedure may have to be duplicated several times until correct. After the setup is
balanced and secure, the lifting bar or sling can be removed from crane or hoist.
5. To remove the engine from the stand, connect the lifting bar or sling to the crane or hoist and raise the engine high enough to take the
weight off the stand. Carefully remove the bolts that connect the four mounting fingers to the engine. Be aware there will be a slight
movement of stand as total engine weight is transferred to crane or hoist.
6. This engine stand has a folding feature that can save space or make storage easy. Just remove the three pins (7) and their clips (8) so the
brace (19) and post (27) can fit flat on top of the center beam assembly (9). The pins and clips can be stored in the open holes.
PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
1. Always store the engine stand in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust,
or any other harmful elements. The engine stand must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2. Lubricate the wheels, casters, zerk fittings, gear and rotating shaft with a general purpose grease.
3. Every engine stand owner is responsible for keeping the engine stand label clean and readable. Use a mild soap solution to wash the
external surfaces of the stand. Contact NAPA for a replacement label if your stand's label is not readable.
