SET-UP PROCEDURE WITH OPTIONAL

M105

HYDRAULIC CHECK

Assemble hydraulic check to mounting bracket and assemble

mounting bracket to tool using washers (30997) and cap screws

(Y157-44).

Measure distance from drill paint to work piece - distance "Y".

Distance "X" between hydraulic check plunger and trip bracket

must be less than distance "Y" to prevent damage to drill point

when it approaches the work piece.

Loosen the Cap screws (Yl57-44) and position hydraulic check

to obtain correct setting for distance "X".

Tighten cap screws (Y157-44) securely before operating unit.

Increase the air flow thru the feed control valve marked "F" by

Opening two (2) full turns from closed position. This will allow drill

to advance rapidly until the trip bracket contacts plunger of hydraul-

ic check.

The hydraulic feed rate adjustment is located at the nameplate

end of the hydraulic check, Rotate extended spindle until the slot

on the spindle is located midway between the highest and the

lowest settings.

Start drill unit and the drill will advance at a rapid rate until the

trip bracket contacts plunger of hydraulic check.

Slowly rotate the hydraulic feed rate counterclockwise for faster

feed rate or clockwise for slower feed rate.

TO CONTROL BREAKTHROUGH

Position hydraulic check so the distance between the plunger and

the trip bracket (distance "X") is less than the distance from the

drill point to the opposite side of the work piece (distance "W").

Set-up of the self-feed drill unit will be the same as explained in

Set-up Procedure, page 1.

IN 40591-( ) HYDRAULIC CHECK ASSEMBLY.

Never apply excessive pressure by a holding device which may

cause distortion of a part.

Apply pressure evenly to parts which have a press fit.

Apply even pressure to the bearing race that will be press fitted

to the mating part.

Use correct tools and fixtures when servicing this tool,

Don't damage "0" rings when servicing tool,

Use only genuine ARO replacement parts for this tool, When or-

dering, specify part number, description, tool model number and

serial. number.

motor housing (50) from the outer sleeve (40).

Using wrenches on flats of ring gear (90) and motor housing, un-

-thread

gearing from motor housing.

Pull spindle (89) and components from ring gear.

Remove bearing (87) and spacer (88).

Turn snap rings (68 and 74) so the open portion will allow the

removal of shafts and gears.

Remove lock nut (93), releasing bearings (92) and spindle (91).

GEARING DISASSEMBLY

Remove chuck from gearing.

Thread adjustment screws (6 and 7) all the way back and push

- the piston rod (47) all the way forward to expose wrench flats of

motor housing (50) from the outer sleeve (40).

- Using wrenches on flats of housing adapter and motor housing,

unthread gearing from motor housing.

If tool has double gearing, unthread lock nut (82) from housing

- adapter (67).

Remove spindle nut (85) from spindle.

_ DIRECT DRIVE MODELS: Unthread and remove Collet nut (116) and

bearing lock nut (114).

GEARING ASSEMBLY

Lubricate gears and needle bearings (70) liberally with ARO

33153 grease and assemble two needle bearings to each

gear.

Assemble one gear to spindle and secure with shaft (71).

Repeat for opposite shaft and gear.

Rotate snap ring, securing both shafts.

Pack bearing (78) with ARO 33153 grease and assemble

bearings (78 and 79) to spindle. NOTE: Bearing (78) is an an-

gular contact type bearing and should be installed with the

identification markings facing away from the spindle.

Assemble washer (81), wavy washers (80) and spindle into

lock nut (82).

Assemble seal (83), nose housing (84) and spindle nut (85) to

gearing.

. ,

DIRECT DRIVE MODELS: Assemble bearing lock nut (114) to

spindle.

Assemble gearing to tool.

Assemble chuck to spindle.

_ Grasp lock nut (82) in one hand and tap the threaded end of the

spindle with a soft faced hammer; spindle and components will

loosen from lock nut.

Remove bearings (78 and 79) and turn snap ring so the open por-

- tion will allow the removal of one shaft, releasing gear. Repeat

for removal of opposite shaft and gear,
