INTRODUCTION:
A new front main bearing is fitted to the above cars. The
bearing has a greater load bearing area but the bearing
material itself remains unchanged.
The increased area has been achieved by using a bearing
without a centre groove. The overall dimensions of the
bearing remain unchanged.
DESCRIPTION:
In order to avoid oil starvation it is essential that the new
bearing shells are fitted only to the above cars and only to
the front main bearing journals. To reduce the possibility of
these shells being fitted to other journals, the locating
tang has been slightly offset on the front main bearing shells,
the front main bearing housing and the main bearing cap.
Due to these dimensional changes it will not be possible to
retrospectively fit these bearings to earlier cars and
reference should be made when ordering parts to Spares
Information Sheet Nu:rnber 4 A 72.
