HYDRAULIC PUMP (Double Gear) 853H (Cont’d)
Assembly
Always use new O–rings and seals when assembling the
hydraulic pump.
When making repairs on hydrostatic and
hydraulic systems, clean the work area before
disassembly and keep all parts clean. Always
use caps and plugs on hoses, tubelines and
ports to keep dirt out. Dirt can quickly damage
the system.
