INSTALLATION AND MAINTENANCE MANUAL
for
MODELS HDL2 AND HDL3 LUBRICATORS
Patent Number 4,598, 796
OPERATION Mounting Dimensions
Therecommendedoperatingrangefor theseLubricators is
50psig (3.5bar/345kPa)to 250psig (17.2bar/1720kPa)
air pressure.TheseLubricatorsarerecommendedfor use
with Ingersoll-Rand No. 50Oil or dieselfuel.
INSTALLATION
TheseLubricators areself-priming andmaybeinstalled
directly into theair starterhousingor mayberemotely
located.Although theseLubricators arecapableof
drawing lubricant from asource4 feet(1.22m) lower than
thepoint of installation. werecommendinstallation as
closeaspossibleto theoil sourcewith piping arrangedso
that theLubricator hasaconstantsupply of oil.
Before initial operation, manually fill the oil supply
line.
OIL INLET
The oil inlet is tappedl/8’-27 NPT.Makecertainthat the
fitting you provide is tightenedto 15to 25ft-lb (20.3to
33.9Nm) torqueto assurethatthejoint andoil supply
hosearevacuumtight andfreeof leaks.Threadsof the
fitting shouldbecleanandassembledwith sealing

Werecommendusingthefuel return line asthesourceof
lubricant. However.oil maybesuppliedfrom aseparate
reservoir or thedieselfuel tank.Whenthedieselfuel tank
is thelubricant source,install anHDLl-37 tank filter in
theoil supply line atthefuel tank.

WhenevergraspingtheLubricator in avise,always
wraptheLubricator in non-marring materialor use
leather-covered or copper-coveredvisejaws to
protectthesurfaceof theLubricator andhelp prevent
distortion.
Werecommendthat you install anewsetof O-rings
wheneveraLubricator is disassembled.
Disassembly of the Lubricator
1. Carefully graspthelargeendof theHousing (1)in

2. Using anappropriatewrench on theknurled sectionof
theAir Inlet (2). unscrewandremovetheAir Inlet
from theHousing.
3. Lift out thePiston (4) andthePiston Spring(7) from
theHousing.
4. RemovetheInlet O-ring (3) from theinside of the Air
Inlet.
5. RemovetheRearPistonO-ring (6), PistonSeal(8)
andFront PistonO-ring (5) from thePiston.
6. RemovetheFilter (9) from theHousing.
ASSEMBLY
General Instructions
1. Always cleaneverypartandwipe everypart with a
thin film of Ingersoll-Rand No. 50Oil.

LUBRICATOR TESTING
1. Install aclear.unpressurizedlubricant supply line to
thelubricant supply sideof theLubricator. Submerge
theendof theline into areservoir of Ingersoll-Rand
No. 50Oil or diesel fuel.
2. Apply 50to 250psi of air to theair inlet to activate
thePiston.Continually apply anddischargeair to the
air inlet to allow piston action.Eachtime the Pistonis
activated,theoil in thelubricant line should move
awayfrom theLubricator. Whentheinlet air pressure
is released,thelubricant shouldtravel backtoward
theLubricator with progressionaftereachcycle. The
amountof progressionwill vary dependingon
lubricant viscosity, fuel line sizeandtemperature.
Typically, Ingersoll-Rand No.50Oil with l/4”
lubricant supply line will pumpapproximately 1” per
cycle at70 in the HDL2 and l/2” percycle at 70in
theHDL3.

3. Apply 50to 250psi of air to thelubricant supply side
of theLubricator. SubmergetheLubricator into anoil
bathfor leakdetection.Upon initial testing,someair
bubblesmayappeardueto thePiston’sdisplacing a
volume of air through theAir Inlet. After afew
seconds.noair leaksshouldappearfrom the
Lubricator.
4. Apply theair supply to theair inlet sideof the
Lubricator andrepeatstep3.
5. An air leakcould becausedby damagedO-ringsor
Sealsfrom wearor improperinstallation. Shoulda
leakoccur.theLubricator mustbedisassembledand
repairedor replaced.
