CAUTION

 

Some components of the Ho-Pac are 
heavy. Use proper lifting and support 
equipment. 

 
The spring mounts are subject to aging and 
require periodic replacement. While spring 
life depends primarily on use, extreme 
environmental conditions and other factors 
can shorten mount life. 
 
1.  Position Ho-Pac on flat, stable surface. 
 
2.  Support top mounting frame to remove 

weight from mounts. 

 
3.  Loosen and remove bolt that secures 

the spring mount to the top frame. 
Repeat until bolt is removed on all four 
(4) spring mounts. 

 
4.  Remove the four (4) bushings. 
 
5.  Lift the top mounting frame off. 
 
6.  To replace spring mount, loosen and 

remove bolt that secures spring to lower 
assembly. Remove spring mount. 

 
7.  To install new spring mount, slide 

washer over bolt. Align spring with hole 
located in lower assembly and insert 
bolt. Tighten bolt to 80 ft/lbs [108 N·m]. 

 
8.  With all four (4) springs installed on 

lower assembly, position the top 
mounting frame over the spring mounts 
and align bolt holes. 

 
9.  Install bushings. 
 
10. Install bolts and tighten to 80 ft/lbs [108 

N·m]. 

 

10.10 Hydraulic Motor 
 
10.10.1 Hydraulic Motor Service 

 

The hydraulic motor has no user-
serviceable parts. Contact Allied’s Technical 
Service for further information. 

 
10.10.2 Motor Flow & Rotation 

 

IMPORTANT 

Incorrect combination of motor and flow 
regulator valve will result in poor 
performance or damage. Refer to Sections 
12.3.1 & 12.3.2 for help with verifying the 
identity of the motor and flow regulator 
valve. 

 

IMPORTANT 

The motor is assembled for clockwise 
rotation. Pressurizing the outlet port will 
damage the motor’s internal components.  
Verify correct installation before 
pressurizing the hydraulic circuit.

Proper Motor Rotation 

 
Motor rotation is clockwise when viewed 
from the shaft end. With the large portion of 
the motor downward, the motor’s inlet port 
(IN) is located on the left-hand side. 

 

 

10.11 Flow Regulator Valve 

  

10.11.1 Flow Regulator Valve Service 

 
The flow regulator valve has no user 
serviceable parts.  Contact Allied’s 
Technical Service for further information.
