8. Hydraulic Reservoir  

Disassembly and Assembly 

 

Chapter Overview 

This chapter provides disassembly and assembly 
procedures for the hydraulic reservoir assembly. 
Cleaning procedures are also included for the hy-
draulic reservoir. 

 Personal Safety 

Improper or incomplete maintenance/repair of a Compact 
Track Loader can be dangerous and may result in ma-
chine damage, injury or death.  
 
Do not attempt to perform any type of repair or mainte-
nance on a Compact Track Loader until you have read 
and fully understood the information in this manual. 
 
Refer to the Operation and Maintenance manual for in-
structions regarding proper machine operation techniques 
before operating any Compact Track Loader. 

Prior to performing any type of service work on a 
Compact Track Loader, read and understand Chap-
ter 1 (Product Safety) for personal safety infor-
mation. 

 

  

Machine Preparation 

Accidental machine starting can cause injury or 
death to personnel working on a Compact Track 
Loader.  
 
As a precaution, disconnect the battery cables from 
the battery terminals, tape the battery clamps and 
remove the key from the ignition switch prior to per-
forming any service work on a Compact Track Load-
er.  
 
Place a “Do Not Operate” tag prominently on the 
machine to inform personnel that the machine is be-
ing worked on.
