Among the longest production run of any (relatively) recent Lister,
the LT1 launched in 1974, production lasting well over 30 years. The
LV, having a slightly greater capacity and output launched in 1983.
Twin cylinder, first LT, then LV were produced for around 11 years, up
to around 1990. The LT2 was only produced for around four years
before giving way to the more powerful LV2 and is a
relatively scarce unit. Both the twin cylinder versions were
considerably outsold by the single cylinder versions.
Single cylinder versions were available in both
clockwise and anti-clockwise rotations; the twin cylinder units were
all anti-clockwise.
With such a lengthy production run there have been
numerous changes to many parts of the engine, so if ordering parts an
engine number is a very useful starting point. As with all Listers
however, the engine number alone may not suffice to identify
changeover points for modified components, so it is not always
possible to acquire all the parts you may need in advance.
Although robustly built, the LT and LV have their problems, the most
significant of which is the absence of any oil filtration provision on
single cylinder versions; there is not even a pick up gauze fitted.
Consequently, unlike most contemporary Listers, significant bearing
and crank wear is a distinct possibility on engines which have not
enjoyed appropriate oil changes. LT2 and LV2 are fitted with an oil
filter. Early engines also suffered from a design fault that allowed
excess oil to the cylinder heads, along with inadequate drain back
provision, in some cases leading to starvation. If you have a choice,
LT series with build versions 1 - 8 are probably best avoided.
Below are listed some useful tips on what to look for when ordering
some of the more common pieces for your LT or LV If you think we have
missed something useful, or got something wrong, please email and let
us know. We welcome any suggestions for improving the usefulness of
this page.
The flat top appearance of the LT and LV is very
similar to that of the T series engines; easiest ways to tell the
difference are size ---- the L series are
noticeably smaller than the T series and the location
of the cylinder head oil feed pipe. On the LT and LV, the external oil
feed pipe to the top of the engine
is attached to a corner of the rocker cover. On
the T series, it is connected directly to the cylinder head.
Lister LT, LV Parts Availability:
Routine Service Items -- 100%
availability. If ordering, please note the following first:
Oil Filter. None fitted to single cylinder versions; just
one fitment for twin cylinder units.
Fuel Filter. There are two patterns of fuel filter used on
the LT and LV range.
1. Small paper element type contained within a metal bowl; the bowl
is secured by a single bolt from the bottom.
2. Small cylindrical filter contained within the fuel tank. Allow
some time for this job; it can be quite a fiddle to remove the old
filter.
Air Filter There are just two air filter elements listed
for the LT and LV; one for single cylinder and one for twin
cylinder. As with many Lister applications however, depending on the
equipment it is powering, the equipment maker may have specified
their own alternative.
External Components --- Near
100% availability.
Charging System.
LT and LV series fitted with a charging system use charge windings
fitted within the flywheel and a regulator mounted close by the
flywheel housing. There have been changes both of supplier and
design over time. If you think you need replacement parts we will
want to know how many terminals on the regulator (a photo is handy)
plus the engine number. Some combinations are obsolete and an
effective repair may include flywheel removal. Our experience is
that generally all the flywheel charge systems leave something to be
desired and are prone to various failings. We are able to supply
test data if you wish to check where your problem may be.
It is important not to run the engine with the battery out of
circuit and any evidence of oil within the flywheel housing should
be investigated as it has a detrimental effect on the charge
windings insulation and function.
Starter Motors
If you are shopping around for a starter motor (if fitted) for your
LT / LV be aware there is often considerable confusion among
non-Lister sources over the issue of rotation. If you have a
clockwise LT / LV you will need an anti-clockwise rotation starter
motor and vice versa. The rotation of a starter motor is determined
by which way the pinion turns as viewed from the pinion end of the
motor. Many starter suppliers simply refer to rotation without being
clear whether they mean the starter or the engine, or indeed without
knowing how Lister define rotation. (the way the flywheel turns when
viewed from the flywheel end of the engine)
Motor availability is good.
Protection devices. Rarely found on
single cylinder versions and not particularly common on twins.
Availability good.

Fuel Injectors No problem.
Fuel Injection Pumps No supply issues. If
you're not sure what you are doing with these pumps, the job is best
left to a person with suitable experience.
Fuel Lift Pump (Where fitted) Readily available.
Gaskets and Joints 100% availabilty; sets or individually.
Internal Components
Good, but not 100% availability. Over time there have been
numerous changes, plus equipment offered that may be long obsolete
now. If buying an LT, unless it is clearly in good order,
Build 1 - 8 are probably best avoided due to component differences.
Complete Engines
New engines long unobtainable. We carry a good selection of core
units and will usually be able to offer a rebuilt exchange engine to
meet your specification. We sometimes have good used engines
available.
Top Tip !
If buying an LT
or LV, satisfy yourself as far as possible it is in good
order. Many have had hard lives in the construction and
associated industries; this plus inadequate maintenance means a
higher proportion than is usual with Lister engines of terminally
tired units. Despite their modest size, parts are not bargain
basement price, so a rebuild
may set you back more than you expect.
Perceptible end float on the crank, or lateral play at the flywheel
are sure indicators you should probably walk away.
