To Rm.{William Robotham - Chief Engineer} from Rm{William Robotham - Chief Engineer}/HH.

Rm{William Robotham - Chief Engineer}/HH.12/SW.27.2.41.

In connection with the scheme for
fitting a General Oil Filter to the B.11 chassis, a sample set supplied to us for test would be definitely a good plan to be sure we are on the best job.

In replying to these people, we still have a criticism to make, i.e., the feed pipe to the filter should be 3/16" and not ¼" as indicated on their layout.

To enable us to fit this job on our B.11., we require a set of the following parts :-

O - Tee piece. 1 Off.
N - Union complete. 1 "
W - Pipe clip. 1 "
K - Pipe inlet (but 3/16 dia not ¼).
L - Banjo fitting complete (3/16 dia. pipe not ¼)
M - Fibre washer. 2 "
A - General oil filter.
B - Cradle.
C - Support bracket - front - EB.4491
D - " " - rear - EB.4492
E - Special studs.
H - Set screws.
T - Banjo fitting complete.
V - Fibre washer for banjo.
R - Union complete.
Q - 5/16. dia. pipe.
S - Tee piece.
