SCRUB SYSTEM
SCRUB DECK ASSEMBLY REMOVAL
1
Remove both scrub deck side skirt assemblies. Then lower the scrub deck and leave the scrub brushes on so that the deck can slide easily
to remove.
2
See Figure 1. Loosen the Hose Clamp (A) and pry the solution feed hose off from the solution manifold barbed Fitting (B).
3
Important General Service Note: When removing hydraulic hoses cap and plug all open hoses and fittings. This will help prevent dirt from
entering hydraulic system and reduce oil leakage.
4
Remove the inside hydraulic hose #41 from the right side brush drive motor (inboard fitting).
5
On the center brush motor remove the #46 case drain hose (small hose).
6
Remove the (4) (C) Nuts and (D) Screws that fasten the Lifting Arms (E) to their scrub deck mount holes. Service Note: Be careful not to lose
the deck lifting arm Bushings (F).
7
Using the steering wheel turn the rear drive wheel so that the drive motor points toward the rear of machine (tire right angle to chassis).
8
Remove the scrub deck lift cylinder Screw (G) from its deck mount. Service Note: Then raise by hand either end of scrub deck to retract (shorten)
deck cylinder to allow needed clearance so the cylinder rod clears the deck-mounting pocket.
9
On the left side of the deck assembly remove the two hoses #16 & #18 as shown. Service tip: Mark hoses for proper re-installation.
10 From the left side brush motor remove the #22 case drain hose, then remove the two bulk head fittings and Nuts (H) (P.N. 56900404) that
are the hose feed connections for the previously removed hoses #16 & #18.
11 Complete the deck removal by pulling the deck assembly out from underneath the machine by maneuvering it around the remaining hoses
and lift arms.
SCRUB DECK ASSEMBLY INSTALLATION
Installation note for the lower scrub deck lift cylinder mounting bolt: Position the bottom end of the hydraulic lift cylinder directly over its deck mount
attachment point (pocket). Then start engine (run at high speed) and lower the cylinder by pressing either the operator increase or decrease switch.
With the cylinder extended insert the Mounting Bolt (G) and tighten to finish the deck installation.
SCRUB DECK CYLINDER REMOVAL
1
Remove both scrub deck side skirt assemblies. Next remove the scrub brushes and then lower the scrub deck.
2
Remove the scrub deck lift cylinder Screw (G) from its deck mount. Service Note: Then raise by hand either end of scrub deck to retract (shorten)
deck cylinder to allow needed clearance so the cylinder rod clears the deck-mounting pocket.
3
Remove the two hydraulic hoses from the cylinder (cap & plug).
4
Remove the front solution tank panel (location operator’s compartment). This allows the needed service access to the top cylinder mount bracket.
5
Remove the hex HD screw that secures the cylinder then remove the cylinder through the bottom of the machine.
SCRUB BRUSH MOTOR REMOVAL
1
Remove the scrub deck assembly by following the Scrub Deck Assembly Removal instructions in this manual section.
2
With the scrub deck assembly removed tip it on its edge to access the non-functioning brush motor and remove the scrub brush on the motor
to be serviced.
3
See Figure 1. Remove the center drive hub retaining Screw (J), then pry off the complete Brush Holder Assembly (K) from the motor shaft.
Service Tip: When experiencing difficulty removing the brush holder assembly (stubborn drive hub) it will be necessary to remove the (3)
(L) Coupler Screws that fastens the brush holder to the drive hub. This will allow the needed work area to use a gear puller to remove the
drive hub.
4
Identify the correct motor hose connections then remove hoses, cap and plug. Next remove the motor mounting hardware and separate the
motor from the deck.
