19 LUBRICATION SYSTEM
To renew the shaft for the idler gear
Consumable products:
POWERPART Retainer (oil tolerant)
The idler shaft for the lubricating oil pump fitted in
the front main bearing cap of six cylinder engines is
now retained by a pin and POWERPART Retainer
(oil tolerant). If it is necessary to renew the idler
shaft on these engines, follow the procedure given
below. The idler shaft used on earlier six cylinder
engines is retained by the interference fit of the
idler shaft in the bearing cap.
The latest engines have a new idler shaft (A3)
which has an oil hole (A2) to provide more
lubrication to the bush for the idler gear. Also a new
lubricating oil pump has been introduced which has
a channel (A4) in the body of the pump. Lubricating
oil from the front main bearing passes down the
channel in the body of the pump to the oil hole in
the idler shaft. The lubricating oil then passes
through the hole in the idler shaft to the bush in the
idler gear.
To remove the idler shaft
Caution: The pin is very hard; if the tap is broken
or the pin cannot be removed, then the other
method on page 19A.15 must be used to remove
the pin.
1 Carefully use an M5 X 0,8 mm taper tap to put a
chamfer in the end of the pin (A1). Remove the tap.
2 Carefully use an M5 X 0,8 mm plug tap to cut
not less than three complete threads in the end of
the pin. Remove the tap.
3 Obtain the parts listed below:
• An M5 X 0,8 mm setscrew, part number
2314E007 or a setscrew which has a thread
which is at least 15 mm long.
• An M5 X 0,8 mm nut, part number 2318A601.
• A spacer with a 15,88 mm or 19,05 mm outside
diameter and an internal diameter of 8,73 mm
which is 9,53 mm long, part number(s), 0920481
or 0330819.
4 Fit the nut fully onto the threads of the setscrew
and put the spacer onto the nut.
