.

g.. Alternately. tighten. the. nuts. (31). to. evenly. draw. the.

housing.down.to.the.cylinder.housing..Be.sure.the.O-ring.

(65).stays.in.place.

.

.

Also,.as.you.tighten.the.nuts.keep.checking.the.shaft.

alignment. by. turning. the. shaft. (use. the. rotator. in. the.

Wanner.Tool.Kit)..If.the.shaft.begins.to.bind.and.become.

difficult.to.turn,.back.off.the.nuts.and.realign.the.shaft..

When. the. pump. housing. is. tight. against. the. cylinder.

housing,.you.should.be.able.to.turn.the.shaft.smoothly.

.

h.. After.all.the.nuts.(31).are.tightened,.insert.cap.screws.

(6),. with. washers. (6),. into. the. two. unused. threaded.

holes. in. the. housing.. Then. remove. the. two. threaded.

studs.and.replace.them.with.the.other.two.cap.screws.

and.washers.

.

i.. Turn.the.shaft.again.to.check.its.alignment.

5. Replace Shaft Seals

.

a...Apply.a.thin.film.of.grease.on.the.seal.protector.tool.(part.

of.the.Wanner.Tool.Kit)..Slide.both.seals.onto.the.tool,.

with.the.spring.side.of.the.seals.toward.the.open.end.of.

the.tool.

.

.

Apply.a.heavier.coat.of.grease.between.the.seals.and.

press.them.together.

.

b.. Apply. a. coating. of. Loctite®. High-Performance. Pipe.

Sealant. With. PTFE,. or. a. comparable. product,. to. the.

outer.surface.of.both.seals.and.the.inside.surface.of.the.

opening.in.the.pump.housing.where.the.seals.will.rest.

.

c... Apply.a.light.film.of.grease.to.the.drive.shaft..Slide.the.

seal.protector.tool.(with.the.two.seals).over.the.end.of.

the.shaft.

.

d...Slide.the.seal.inserter.tool.(from.the.Wanner.Tool.Kit).over.

the.seal.protector.tool,.and.press.the.seals.completely.

into.place..Tap.the.tool.with.a.soft.mallet.to.firmly.seat.

the.seals.

6. Adjust Camshaft Endplay

.

a.. If.the.three.set.screws.(4).are.in.the.cylinder.housing.

(5),.remove.and.clean.them.

.

b.. Insert.the.centerbolt.(1).into.the.hole.in.the.center.of.the.

cylinder.housing..Turn.it.in.to.move.the.bearing.adjusting.

plate.(61).and.cup.tight.against.the.bearing.cone.

.

c.. Back.out.the.centerbolt.two.full.turns,.then.turn.it.back.

in.again.until.it.is.tight.against.the.adjusting.plate.(61).

.

d...Back.out.the.centerbolt.exactly 1/4.of.a.turn.

.

e.. With.a.plastic.mallet.(or.a.regular.mallet.and.wooden.

board).to.prevent.damage.to.the.shaft,.rap.the.end.of.the.

shaft.three.or.four.times..This.will.provide.about.0.006.

in..(0.15.mm).endplay.in.the.shaft.

.

f... Apply.removable.threadlocker.to.the.threads.of.the.three.

cleaned.set.screws.(4).

.

.

Screw.the.three.set.screws.(4).into.the.cylinder.housing.

until.they.contact.the.bearing.adjusting.plate.(61).

.

g...Remove.the.centerbolt.(1).

7. Install Plungers

.

NOTE: If the plungers (23) have been removed from the 

valve plungers (54), do not reuse them. Install new ones 

instead.

.

a...Rotate.the.pump.shaft.so.the.piston.is.in.the.top-dead-

center.position.

.

b...Place.a.plunger.on.the.exposed.screw.end.of.the.plunger.

guide.tool.from.the.Wanner.Tool.Kit..The.larger-diameter.

side.of.the.plunger.should.face.the.tool.

.

c... Screw.the.guide.(with.the.plunger).into.the.valve.plunger.

(54).until.tight.

.

d...Hold.the.single.bottom.handle.of.the.guide,.and.turn.the.

double.top.handle.to.force.the.plunger.to.seat.on.the.

valve.plunger..This.is.a.press-fit.—.when.installed,.the.

plunger.should.be.tight.against.the.shoulder.of.the.valve.

plunger.

.

 

NOTE:  Do  not  remove  the  plunger  guide  until  the 

diaphragm is installed (see below).

.

e...Install.the.diaphragm.as.outlined.below,.then.repeat.the.

procedure.for.the.other.two.plungers.and.diaphragms.

8. Reinstall Diaphragms

.

a...With.the.plunger.guide.tool.still.screwed.into.the.valve.

plunger.(54),.pull.the.valve.plunger.up.until.the.cross-

holes.in.the.valve.plunger.are.exposed.

.

b.. Insert. the. plunger. holder. (from. the. Wanner. Tool. Kit),..

through.the.top.hole.—.to.hold.the.plunger.(3).away.

from.the.cylinder.housing,.and.to.keep.the.valve.plunger.

from.turning.when.the.diaphragm.is.being.installed.

.

c... Place.the.diaphragm.().onto.the.plunger.(3),.ridge-

side.out.

.

d...Center.the.diaphragm.follower.(1).on.the.diaphragm.

.

e...Place.the.O-ring.(0).onto.the.follower.screw.(19).

.

f... Apply.a.small.amount.of.threadlocker.to.the.threads.of.

the.follower.screw.

.

g.. Insert. the. follower. screw. (with. O-ring). through. the.

diaphragm.follower.(1).and.diaphragm.(),.and.screw.

it.into.the.valve.plunger.(54).

.

h...Hold.the.plunger.holder,.and.torque.the.follower.screw.

to.18.in.-lbs.(.0.N-m).

.

i... Repeat. the. above. procedure. for. the. plungers. and.

diaphragms.of.the.other.two.cylinders.

.

j... Fill.the.reservoir.with.fresh.oil.and.prime.the.pump,.as.

outlined.in.the.Fluid-End.Service.Section.

9. Reassemble Pump Head

.

Reassemble.the.pump.head.as.outlined.in.the.Fluid-End.

Service.Section.
