DISTRIBUTOR
Using an Allen key* remove two screws 40.
• Withdraw distributor 83 together with air motor end plug 81 and 'O' rings 82 & 31 taking care not to
drop ball 79 and push rod 78.
• Using an Allen key* remove four countersunk socket head screws 58 and withdraw stroke stop 57.
• Pull out two air supply tubes 59 and four 'O' rings 60.
• Assemble in reverse order of dismantling
ENSEMBLE PISTON HYDRAULIC PISTON & AIR MOTOR ASSEMBLY
• Wrap adhesive tape around hydraulic piston 54 thread and move assembly backwards slowly and
firmly. Using circlip pliers• remove circlip 52 and front seal 51.
• Remove 'O' rings 76 and 77.
• Using two spanners* separate the hydraulic piston 54 from air motor casing 75. Shim adjustment ring
55, movement pivot 56 and 'O ring 101 will come out with hydraulic piston 54.
• Remove air motor assembly out of air motor casing 75, remove circlip 61 using circlip pliers*, then tap
air motor casing 75 on bench to free components.
• Parts 62 to 74 can be pulled out as an assembly, taking care not to drop pin 74.
• Remove bearing 62, planet gear spindle 63, three planets 64, planet gear 65 and spacer 66.

in hand).
• Place rear end plate 72 in vice with soft jaws.
• Using a pin punch* tap centre of rotor 70 to remove bearing 73. (turn rotor 70 upside down and bearing
73 will come out).
• When assembling air motor, rear side of rotor 70 must just touch rear end plate 72 without any axial
gap, (any existing gap will disappear
when bearing 73 is fully located.
• When inserting air motor into air motor casing 75 carefully align parts so that pin 74 locates in centre
hole between spin on/off ports of air motor casing 75 and rear end plate 72.
• When assembling hydraulic piston 54 onto air motor assembly, tighten parts by hand and blow air into
one of the outer ports of air motor casing 75, checking to see air motor rotates freely.
• When assembling front seal 51 ensure larger diameter faces rear of tool.
