Land Rover Propeller Shafts Rover Manual

							PROPELLER SHAFTS
New Range Rover25 The coupling is a rubber moulding. The coupling is designed to transfer rotational drive from the
transfer box to the front propeller shaft without wind-up, but simultaneously compensating for
small amounts of misalignment and absorbing torque and vibrational loading. Each of the six
attachment holes is lined with a metal bush. The bush is required to prevent compression of the
coupling by the attachment bolts and nuts.
The splined shaft has 42 splines which mate with corresponding splines in the input shaft of the
front differential. A shroud is pressed over the splined shaft. The shroud seals against an O-ring
seal on the front differential input shaft, preventing the ingress of dirt and moisture. The splines
allow for movement of the propeller shaft caused by small movements in the transmission and
transfer box mountings.

New Range Rover27 The rear propeller shaft assembly consists of front and rear shaft assemblies and a centrally
mounted shaft bearing. The rear propeller shaft assembly has an overall length of 1280 mm.
Front Shaft Assembly
The front shaft assembly consists of a CV joint at the front and a splined shaft at the rear. The
front shaft consists of a tube with welded, splined shafts at each end.
The forward splined shaft accepts the CV joint which is secured with a circlip. The CV joint is
packed with grease and sealed on both sides with metal shrouds to prevent the ingress of dirt
and moisture. The CV joint has six radial holes which provide for the attachment to the transfer
box rear output flange. The joint is secured to the output flange with six bolts, which screw into
threaded holes in the flange. Three shims are fitted under each pair of bolts. The shims have
tabs which are bent to secure the bolts. The CV joint is not a serviceable item and failure will
require replacement of the rear propshaft assembly. The rear splined shaft mates with splines in
the rear shaft universal joint. A threaded hole is provided in the splined shaft to secure the front
and rear propeller shaft sections together. A machined surface on the shaft accepts the shaft
bearing, which is a press fit.
Shaft Bearing Assembly
The shaft bearing assembly consists of a pressed steel housing, a rubber bush and a ball
bearing. The rubber bush is bonded into the housing. An internal metal ring, bonded to the
bush, allows for the bearing to be press fitted into it. The rubber bush allows for small deviations
in alignment and also absorbs vibrational forces. The shaft bearing assembly is located on
studs, which are integral with the body, and secured with flanged nuts.
Rear Shaft Assembly
The rear shaft assembly consists of a universal joint at the front and a CV joint at the rear. The
rear shaft consists of a tube with the welded universal joint at one end and a welded splined
shaft at the opposite end.
The universal joint is welded to the rear shaft tube. The opposite end of the universal joint has a
splined bore which mates with the splined shaft on the rear of the front shaft assembly. A bolt
and washer is fitted through the splined bore and screws into the splined shaft on the front shaft
assembly, securing the front and rear shaft assemblies together.
The splined shaft accepts the CV joint which is secured with a circlip. The CV joint is packed
with grease and sealed on both sides with metal shrouds to prevent the ingress of dirt and
moisture. The CV joint has six radial holes into which, six knurled bolts are pressed. The
knurled shanks of the bolts provide a secure mounting for each bolt, preventing them from
rotating. Three shims are fitted under each pair of bolts. The shims have tabs which are bent to
further secure the bolts. The CV joint is secured to the input shaft of the rear differential with six
flanged nuts. The CV joint is not a serviceable item and failure will require replacement of the
rear propshaft assembly.
