IMPORTANT FACTS ABOUT THIS MANUAL
The Rugby®model SF-26B, SF-28A, and SF-623 hoists are installed with a sub-frame. The model
LR-26B, LR-27B, LR-28A, and LR-623 hoists are installed without a sub-frame. If you are install-
ing an LR-26B, LR-27B, LR-28A, and LR-623, this manual (Part #03 5804) is the correct manual.
If you are installing an SF-26B, SF-28A, or SF-623, this manual (part #03 5804) is the incorrect
manual to use. The correct manual (Part #03 6077) should be obtained and used. This manual
(part #03 5804) covers only the installation of the hoist itself and the rear hinge.
This manual does not cover the installation and operation of the body prop or body props. The
installation and operation of the body prop or body props is covered in the manual #03 6034. The
#03 6034 manual is included in every LR-26B, LR-27B, LR-28A, or LR-623 application sold by
Rugby Manufacturing Co.
This manual (part #03 5804) does not cover the installation and operation of the hydraulic system.
There are four different types of hydraulic systems available for some or all of the hoist models
(LR-26B, LR-27B, LR-28A, or LR-623).
The four types of hydraulic systems and their respective installation and operation manuals are listed
below:
Installation and Operation Type of Hydraulic System
Manual Part Number
03 5679 Drive shaft driven pump with mid-latch cable
03 5650 Direct Mount Pump with tower control
03 5669 Electric double acting with push button control
03 5670 Electric single acting with push button control
Depending on the type of hydraulic system purchased, one of the above manuals will be included in
every LR-26B, LR-27B, LR-28A, or LR-623 sold by Rugby Manufacturing Co. Before installing
one of the before mentioned hoists, be sure you have the proper manuals to do the job. If you do not
have the correct manuals contact Rugby Manufacturing Co.

"CAUTION"
The hydraulic system supplied with a given hoist manufactured by Rugby Manufacturing Co. is
made up of components (pump, valves, reservoir, hoses, cylinder, etc.) that are designed to be
compatible with each other.
If you substitute hydraulic components, it is your responsibility to BE SURE they are compatible
with the other components supplied by Rugby Manufacturing Co. Incompatible hydraulic
components may cause failure of the hoist which in turn could damage the truck, damage other
property, and cause human injury or death.
All Rugby Manufacturing Co.'s liability and warranty for a given hoist will be voided if it is
determined by Rugby Manufacturing Co. that substituted hydraulic components were used that were
incompatible with those supplied by Rugby Manufacturing Co.
Several hoist hydraulic parameters are given in the following table. These parameters are given as a
general guide. To ensure component compatibility, consult Rugby Manufacturing Co.

The following step-by-step instructions are to be followed as a general guideline when
installing the LR-26B, LR-27B, LR-28A, or LR-623 hoist assembly:
Warning: Welding, oxy-fuel cutting, or grinding sparks can cause fuel to ignite which
in turn can lead to injury or death. "Always" take adequate steps to avoid
ignition of fuel from fuel tanks when welding, grinding, or oxy-fuel cutting
during equipment installation.
Warning: Heat from the truck's exhaust system can cause hydraulic component failure
and may lead to a fire which could cause injury or death. "Always" install
equipment in locations where heat from the exhaust system will not damage
any hydraulic component.
Warning: Being under a raised body can result in serious injury or death should the
body inadvertently descend. "Never" position yourself or allow others to
position themselves under a "loaded" body. "Always" prop the "unloaded"
body up using the body prop or body props supplied. "Remember", body
props are to be used only on an unloaded body.
Warning: Malfunctioning equipment can cause property damage, injury or death.
"Always" have faulty equipment repaired before continuing its use. If
required, consult the manufacturer.
Warning: Overloading of a truck can cause truck component damage, or an accident
which may cause injury or death. "Never" exceed the gross vehicle weight
(GVW) or the gross axle weight (GAW) rating of your vehicle.
Warning: Not installing or operating equipment correctly can cause component
damage, or an accident which may cause injury or death. "Always" install
and operate equipment in accordance with manufacturer's instructions. Read
and understand this manual fully before proceeding.

LR-26B, LR-27B, LR-28A, & LR-623 ASSEMBLY INSTRUCTIONS
NOTE: If you are installing a SF-26B, SF-28A, or SF-623 refer to manual with
Part #03 6077.
1. Mark the location for the rear hinge. This location should be immediately behind a truck
cross member, approximately 32" behind the center of the rear axle on single axle trucks.
Refer to Fig. #1 and the charts for the specific hoist model you are installing.
NOTE: If a distance of 38" is exceeded between the rear hinge and the center of the rear axle,
additional reinforcement of the truck frame will be required.
2. Cut a notch in each truck chassis frame rail as illustrated in Fig. #2.
3. Position the rear hinge angle in the notch cut in Step 2. The rear hinge angle is 38 1/16" wide
and should be centered side to side in the notch as illustrated in Fig. #3. Weld the rear hinge
angle to each of the truck chassis frame rails.
