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-9500 Standalone Jet Setup and Operation
manual 3A5928.
This manual presents repair procedures for the HV-9500 jet series:
HV-9500 standard jet
HV-9500R –right side valve mount
HV-9500-60Z –large capacity syringe option
HV-9500HF –optional heated feed tube for high flow dispensing
The extent of jet disassembly depends on which kits are being installed. When noted,
use the tool specified.
For all jet kits, remove and keep:
Nozzle plate and two screws with two washers each
(HV-9500HF) Upper and lower feed tube enclosures and two screws.
Syringe holder and two screws
Top cover and two screws
Dovetail plate and four screws
Mounting plate and two screws
For the Bushing Kit and Heater Kit (BK-2001 and HK-9500):
Detach the heater block (keep for BK-2001; discard for HK-9500)
Remove and discard the heater seal, washer, bushing, and jet hammer spring
For the Jet Repair Kit (JK-9500):
Detach the heater block (keep unless also installing HK-9500)
Remove and discard the heater seal, washer, bushing, and jet hammer spring
Remove and discard these jet parts:
Main (jet hammer) air cylinder
Pivot bolt
Lever
Solenoid valve
Silencer
Section 2.6 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. Remove built-up threadlocker as necessary.
After reassembling the jet, the jet hammer gap must be set using the procedure in
Section 4.
