Disconnect hose from fluid section.
5.Disconnect and remove fluid section from gearbox, including Connecting Rod Assy. (See"Fluid Pump Disconnect, page 10)
6.Remove four nuts (page 20, Item 23) on the engine side of (Item 18) from screws (Item 24) which pass through spacer tubes (Item 15). This will allow removal of Gearbox & Clutch Assembly from "Holder- Manifold" (Item 18).
7.Pull the cog belt loose from the engine shaft cog pulley and remove the gearbox/clutch assembly from the rest of the unit.
8.Place gearbox in vice by gripping the flat part of the drive crank allowing the clutch assembly to face up. Use caution and not allow gearbox to swing and damage casting against vice.
9.Hold coupling screw, with 13/16" wrench, then with 5/16" allen wrench, screw differential screw out of coupling screw and gearbox shaft.
10.Screw large end of differential screw into coupling nut assembly and pull out of clutch assembly.
11.The clutch can now be removed Spacers, removable spacer, replacement clutch, bearings, retaining rings should be inspected and replaced if needed. (Items 3 through 8 on Parts List).
Install new clutch as follows:
1.With gearbox held as described in Step 8 above, place first spacer and bearing onto gearbox shaft.
2.Insert snap rings (2 into recesses of cog pulley portion of clutch. Place cog pulley portion of clutch with cog belt attached onto shaft.
3.Place second spacer into cog pulley portion of clutch. This spacer will rest on the first bearing installed.
4.Insert second bearing on top of upper snap ring.
5.Lay removable spacer on top of last bearing. If the clutch air gap is larger than .028", do not use removable spacer. Put spacer over removable spacer, if used, and top bearing.
6.Place coil portion of clutch down onto cog pulley portion of clutch and center on gearbox shaft.
7.Screw differential screw into coupling screw and nut until 1/16" is showing.
8.Push coupling nut assembly into clutch assembly until it comes to a positive stop. (Differential screw comes into contact with the threaded gearbox shaft.)
9.With 13/16" wrench on coupling screw and 5/16" allen wrench in differential screw, simultaneously with both wrenches screw coupling nut assembly into gearbox shaft by turning clockwise until a positive stop is reached.
10.Hold coupling nut assembly and tighten diffential screw to 30
11.Place cog belt over cog pulley portion of clutch. Loosen set screws until set screws are approximately 1/4" above block tensioner.
12.Reassemble the spacers onto screws. Simultaneously lift gearbox
assembly with clutch into position by placing cog belt over engine shaft log pulley and inserting the four screws into
13.Slightly loosen screws (4).
14.Evenly tighten Set Screws until flush with tip of block tensioner.. Check tension on cog belt by pressing hard with thumb. Proper tensioning should allow for approximately 1/8". If belt is too loose, tighten set screws further.
15.Replace connecting rod and fluid section. Preplace front cover on gearbox. Connect hose to fluid section.
16.Connect the clutch and board leads. Connect spring to spacer tube.
17.Replace the splash shield.
18.Test the clutch for proper operation
19.Replace clutch covers.
Maintenance
REGULAR MAINTENANCE
1.Always stop the pump at the bottom of its stroke when you take a break or at the end of the day. This helps keep material from drying on the rod and damaging the packings.
2.Keep the displacement pump packing nut/wet cup1/3 full of TSO (Throat Seal Oil) at all times. The TSO helps protect the packings and rod.
3.Inspect the packing nut daily. Your pump has a patented "Triple Life Packing System". Packing life will be extended a minimum of 3 times if the following Packing Tightening Procedure is followed:
