Lotus Service Notes
FL.3 - LUBRICaTION
The engine and transmission should be inspected for evidence of oil leaks at every service, and the trans-
mission oil renewed at intervals specified in the Maintenance Schedule.
The transmission should be drained after a run when the oil is warm, flows more readily, and the impurities
are still held in suspension. a hex. head drain plug is provided in the bottom of the transmission crownwheel
housing. after allowing a sufficient drain period, thoroughly clean the drain plug before applying PTFE tape
around the thread, fitting a new sealing washer and tightening to 39 Nm.
a level/filler plug is located in the left hand side of the transmission case. With the vehicle at normal ride
attitude, the oil level should be within 5mm of this filler plug hole. For oil specification refer to Section OK. after
refilling, re-check the oil level at normal running temperature after a run. Finally use a new sealing washer and
tighten to 39 Nm.
FL.4 - DRIVE SHaFTS
Each of the two driveshaft assemblies comprises a steel shaft with a constant velocity (CV) joint at each
end, and is used to transmit the drive from each differential output gear to the rear wheel hub. The longer right
hand driveshaft assembly features an outrigger bearing bolted to the right hand side of the cylinder block, with
a shaft extending from the inboard CV joint into the transmission housing.
The inboard joints are of a plunging tripod design to accommodate driveshaft length variation with sus-
pension travel, whereas the outboard joints are high efficiency 6-ball fixed length type. Replacement outboard
joints include the main driveshaft, outboard C.V. joint and gaiter. Replacement inboard joints include the inner
C.V. joint and gaiter kit, with the extended stub shaft of the RH joint also including the support bearing and
mounting bracket.
The joints themselves are packed with grease on initial assembly, and are maintenance free. It is however
vitally important that the protective gaiters are carefully inspected at service intervals, to check for splits, tears
or punctures, since the joint will deteriorate very quickly once contaminated with dirt or water. Damaged gaiters
should be renewed immediately, once the servicibility of the joint has been established.
CAUTION: The outboard C.V. joint gaiter can suffer 'pinch' damage if the joint is subjected to extreme articula-
tion off the car, or during driveshaft removal/refitment.
