Hydraulic spool valves - fitting additonal slices
N.B. Please remember cleanliness is most important when working on the hydraulic system!
Fitting
Remove aluminium
kick plate from infront of spool lever
Disconnect all
hydraulic pipes from underneath spool and cover pipe ends to keep
dirt out.
Remove nuts from
the 3 spool valve securing bolts
Lower valve down
from underneath the floor and remove from the machine.
Undo the clamp
bolts on the valve block. Lift end plate off first followed by the
valve slice. Then remove bolts from remaining end plate. Take care
not to damage or loose the 'O' rings.
Re-assemble with
the new bolt kit and extra slice. DO NOT OVERTIGHTEN BOLTS - or the
spools will stick.
Remove the spool
securing bolt nearest to the seat and move it over one hole after
piercing floor mat to suit.
Cut a hole in the
floor mat for second lever.
Fit lever to new spool.
Refit spool block
under floor and tighten bolts.
Fit two 1/2 x 3/8
adaptors into spool slice using sealing washers provided.
Fit bulkhead
adaptors and quick release couplings into rear mounting bracket
Connect Original
pipes back onto spool
Connect new pipes
N.B.- Fittings on spool end of pipes may have to be bent down
slightly to get adequate clearance - If they do, tighten pipe onto
spool first and then bend down slightly by hand only.
Fit rubber boot
over spool levers and glue in position
Refit kick plate.
Run machine and
check for leaks.
N.B. If fitting a
Lely Centreliner it may be found necessary to remove the restrictors
from the hydraulic rams for them to work effectively.
