Specification:
All Old Style Lister Engines must be run on Synthetic
lubricating oil. Straight mineral oils are
not suitable, neither are oils of less detergency than specified. The use of Synthetic lubricants will give longer periods between overhauls
and extend engine life.
Mixing of Oils:
DO NOT MIX OILS! If an engine has been on straight mineral oil for more than 250 hours since
completely overhauled (or since new) before it is changed to Heavy Duty
(Detergent) Lubricants, the deposits formed by the straight oils may be
dislodged by the letter and choke the oil ways and filters. For this reason it is
necessary to flush the engine thoroughly with Heavy Duty (Detergent) oil and
change the oil after 150 hours and then resume normal changes every 250 hours.
The filters must receive frequent attention during this initial period. Sometimes Heavy Duty (Detergent) oils increase the oil consumption, in which
case a heavier grade may be used.
DO NOT MIX TWO DIFFERENT BRANDS OF OIL. THOROUGHLY DRAIN OFF OIL OF ONE BRAND
BEFORE CHANGING TO ANOTHER LUBRICATING OIL. ADDITIVES ARE NOT CONSIDERED
NECESSARY AND SOME CAN HARM THE ENGINE.

Lubricating Oil System:
Lubrication is by a plunger type pump operated by a cam on the camshaft. The
pump feeds a generous supply of oil to the main bearings and to the trough into
which the dipper of the connecting rod big end dips. The big end bearings are
lubricated from below by a hollow dipper in the 12/2 & 16/2 engines, and by oil
holes from above in the single cylinder engines. The piston, cylinder and other
working parts are lubricated by splash. The lubricating oil pump of the single cylinder engines, mounted the end of the
crankcase below the fuel pump is fitted with a hand priming lever. The two
cylinder engine is primed from inside by reaching through the crankcase and
working the oil pump plunger with the thumb until the oil is seen to flow down
over the main bearings. The plug on the top of the pump fitting may be slackened
if necessary to check that the pump is working. An oil pressure indicator gauge
and tap can be supplied if specialty ordered. The valve stems are lubricated
rated from small oil reservoirs in the cylinder head, and the rocker shaft is
provided with its own greaser. Near the valve tappets is a brass plug marked "OIL". This is for applying oil to
the camshaft bearing if the engine has been standing idle for a long time.
Tappet heads and push rod heads are cupped to enable them to hold their own
supply of oil for a reasonable time.
Before Starting Engine for the First Time of After Overhaul:
Remove crankcase door and fill troughs under connecting rod (or rods) with
lubricating oil.
Apply oil into each oil hole in top of big end bearing.
Open oil filler and fill engine sump to within ½ it, (12.7 min.) of the top of
oil filter.
Operate lubricating oil pump by hand or rotate engine by starting handle until
oil flows down over main bearings and into dipper troughs on twin cylinder
engines.
Close up crankcase and fill recesses in cylinder head with engine oil for valve
lubrication. Also fill cups in push rods and tappet heads.
Remove brass plug near tappets, marked "Oil", and pour in ¼ pint of oil.
Fill rocket shaft greasers and give several turns to lubricate valve rockers.
Lubricate any AUXILIARY MACHINERY driven by the engine.
