SERVICE

3.Place the motor plate on an aluminum plate latch end up in an arbor press.

4.Install latch parts with Latch Installation Tools (part num- bers 05062 and 05879) in the following order:

a.Latch (in the open position)

b.Latch Washer

c.Four Wave Springs

e.Latch Washer

f.Four Additonal Wave Springs

g.Spring Backup

h.Assembly Guide

i.Wire Retaining Ring.

Place pusher over the guide and press with an arbor press until wire retaining ring snaps into place.

5.Install the bearings in the motor chamber in the same manner used for the motor plate (Step 3).

15.Install a white backup ring and a quad ring seal in the seal counter bore of the motor control block.

16.Push the motor control block over the drive hex. Align the roll pins and push squarely using an arbor press until mated with the motor chamber. Install two 1/2-13 x 4-1/2 inch capscrews and tighten to 60 ft lbs/81 Nm.

17.Replace the control valve in its bore followed by the tapered washer (large diameter or taper facing up) and retaining ring. Make sure the retaining ring is properly seated in its groove (tapping on the ring with a small punch may be required). When replacing the lever, make sure the setscrew enters the hole in the valve stem.

18.Install the small piston cup seal in the motor control valve block with the lips down. Install the seal washer and larger cup seal with the lips facing outward.

Note:

Separate support at four corners is not necessary.

6.To assemble motor components, start by sliding the drive hex through the motor chamber from the control valve side.

7.Place the key in the drive hex and slide the drive gear in place over the drive hex and key.

8.Install the idler gear in the bearing/counter bore of the motor chamber.

9.Place an o-ring in the irregular groove of the motor chamber and apply grease to retain it in place.

10.Install a white backup ring followed by a quad ring through the bearing and into the seal groove of the motor plate.

11.Slide the motor plate over the drive hex. Align the dowel pins and idler gear, then press together until the motor chamber and motor plate come together.

12.Secure the two sections together using the two 3/8-16 x 1-3/4 inch capscrews, tighten to 25 ft lbs/34 Nm.

13.Place the thrust washer over exposed end of the drive hex on the control valve side of the motor chamber (grey or brass side down). Install the thrust backup washer with its small diameter outward.

14.Place the gasket on the motor chamber with a light fi lm of grease or oil for retention. Align with the dowel pin and o-ring counter bores. Install the two o-rings in the small counter bores of the motor chamber.

FLOW SLEEVE AND ACCUMULATOR REASSEMBLY

1.Using an arbor press and an aluminum disc or Accumu- lator cylinder Puller (part number 05640) to protect the fl ow sleeve, push the fl ow sleeve (with the eight holes on its end facing up) into the fl ow sleeve tube (o-ring groove up) until it is fl ush with the tube. Be sure to lubricate the entire bore of the fl ow sleeve tube prior to assembly.

2.Install the four 1/4 x x1-1/2 inch push pins (tapered end up) in the fl ow sleeve.

3.Install the two 3/16 x 1-1/4 inch push pin (tapered end up) in the automatic valve body. Install the automatic valve (small diameter fi rst) into the automatic valve body.

Note:

The push pins must be installed so that the flat, ground faces bear on the flange of the automatic valve.

4.Align the roll pin and place the automatic valve body (with the side holes up) on top of the fl ow sleeve. Allow the automatic valve to drop and pilot into the bore of the fl ow sleeve.

5.Using an aluminum disc or Accumulator Cylinder Puller (part number 05640) to protect the parts, push the auto- matic valve body into the fl ow sleeve tube until the shoulder of the automatic valve body stops on top of the fl ow sleeve tube.

6.Install the piston (small end fi rst) into the fl ow sleeve as- sembly from the automatic valve body end.
