1. Required Tools and Parts
This document describes procedures for installing these HV-2000 jet maintenance kits:
BK-2001: Replaces the heater block bushing, and the jet spring, washer, and
heater seal.
HK-2001: Replaces just the heater block assembly (heater block with bushing
and cable assembly). Also includes the jet spring, washer and heater seal.
JK-2001: For optimal jet performance and to prevent damage to the jet, the jet
hammer cylinder, lever, shoulder bolt, solenoid, muffler, and heater block
assembly should be periodically replaced.
Whenever the jet hammer spring is removed, the jet hammer gap must be set before
dispensing can proceed. The gap set fixture and specific tools required for this
procedure are included in the Advanjet Jet Maintenance Kit (Part no. JKT-2000).

2. Jet Disassembly
2.1 Overview
Note: It is important to flush and clean the jet valve prior to making repairs. Follow the
steps for cleaning the jet valve in the HV-2000 Jet Setup and Operation manual
3A5855.
To avoid personal injury, move the
nozzle close to the paper so there is
minimal misting of the solvent during
flushing. Be sure there is proper
ventilation and wear appropriate eye
and skin protection as instructed by the
solvent manufacturer.
Turn off the power switch and the air switch on the HV-2000C Jet Controller before
beginning disassembly of the jet valve. Refer to the HV-2000C Jet Controller Setup and
Operation manual 3A5856.
The extent of jet disassembly depends on which kits are being installed.
For all repair kits, remove and keep:
Nozzle plate and 2 screws with 2 washers each
Top cover and 2 screws
Mounting plate and 2 screws
For the Bushing and Heater Kits (BK-2001 and HK-2001):
Detach the Heater Block; keep for BK-2001, discard for HK-2001
Remove and discard the heater seal, washer, and jet hammer spring
For the Jet Maintenance Kit (JK-2001), remove and discard jet parts in this order:
Heater block and cable
Heater seal, washer, and jet hammer spring
Hammer air cylinder
Pivot bolt
Lever
Bullet solenoid valve
Muffler
When noted, use the tool specified.
Section 2.6.3 provides a checklist of parts and screws that should be set aside. Take
care to set aside screws as they are removed so they can be easily located for installing
the new parts.
