MAINTENANCE GUIDE FOR THE JV-60 KL FLOWMETER
Cleaning, inspecting or repairing an JV-60 KL gear flow meter is easily
accomplished by following the procedures below.
1. Remove the pickup sensor (not shown) from the flow meter body (5).
2. Remove the hex bolts (6) with a 3/16" key wrench.
3. Re-engage 2 opposing bolts diagonally from each
other by a few threads to avoid stress on the
shafts and locator pins during housing separation.
4. Holding the upper housing (5), gently tap the
opposing bolts (6) to separate the lower housing
(1). Do not use chisels or screwdrivers to split
and pry apart the housings - this may damage
the gears and locating pins.
5. After separation, inspect the gears (3) and
bearings (7). Inspect and clean the gears taking
care not to dislodge the bearings (7) located in the
housing. The meter should be returned to the
factory for any bearing repairs. Note: Meters
purchased before May, 2001 may have shims
installed. Refer to drawing #JVM6900B for this
model.
6. After cleaning, all parts can be reinserted into
their previous positions. Check for free & easy
rotation.
7. Replace O-ring (4) if deformed.
8. Keep meter housings parallel during reassembly
and align index marks (8). Both locating pins
must be in place (2).
9. Replace hex bolts and slowly tighten to at least
15 Nm. (This is hand tight). Do not force the
housing closed. Do not use a hammer. Over
tightening will not cause damage but may restrict
operation if internal surfaces are not completely
clean.
10. After reassembly, gently blow air into meter so
gears spin. This should be clearly audible given a
moderate background noise level.
11. Clean any debris from the pickup port & hand
tighten the pickup sensor. Avoid over tightening
as this may damage the meter.
Do not over tighten sensor *
The bearings should be lubricated prior to storage.
Never allow contact with water without immediately
drying and lubricating after use.
