PREHEATER ПЖБ-200Б ON TRAC-
TOR
To install the heater (see Figs. 13, 14),
follow the sequence, as follows:
а) install enclosure (5) on the diesel-
engine oil casing and fasten it with
four М8х16 bolts with washers;
b) assemble heater boiler (10), together
with brackets (18) and (6), with two
clamps (14), connect them with four
М8х14 bolts, nuts and washers; mount
a branch pipe in assy with hoses onto
the boiler, insert the boiler exhaust
branch pipe into the enclosure (5) throat
and fasten the unit with two М10х20
bolts through washers to the semi-
frame girder and with three М8х16
bolts, through washers, to the clutch
housing (М8х16 bolts attach the bottom
hatch of the clutch housing; М10х16
bolt with a clamp on the left-hand side
— a differential lock-up pipe);
c) fit fan (13) on bracket (16) in assy
with electric motor (15) and fasten
through a clamp with two М6х30 bolts,
washers and nuts;
d) install bracket (23) and clamps on the
left-hand side of the clutch housing
and fasten them with two М16х32
bolts with washers; attach electro-
magnetic valve (22) by means of a
clamp and М6х30 bolt, with nut and
washer;
e) install fuel tank (24) in assy with a tap
and O-ring, through two rubber gas-
kets onto the bracket (23), and fasten
with four М8х16 bolts, with nuts and
washers;
f) remove plugs from the left- and right-
hand sides of the diesel-engine Д-243
cylinder block and fit instead a wa-

g) remove the heater boiler (10) togeth-
er with the delivery pipe (2); locate
the upper part of the pipe (2) between
the girder and the diesel-engine
block;
h) couple the water discharge tube (4) to
the boiler (10) branch-pipe, as shown
in Fig.;
i) connect boiler and electromagnetic
valve (22) to fuel pipeline 20;
j) connect the tap (26) of the fuel con-
tainer to the electromagnetic valve
(22) through hose 25;
k) couple fan (13) to boiler air branch-
pipe (11) through a hose; fasten the
latter with a coupling clamp;
l) on the cab front wall, on the left-hand
side, control panel (29), fasten it with
two М6х12 bolts, nuts and washers.
Not to adversely affect the tractor ex-
terior, nuts and washers should be
placed from the inside of the cab. In-
sert a protection rubber sleeve into a
20 hole provided in the cab side
column and thread cable bundle 28 to
the preheater control panel. Connect
electric cable in accordance with the
diagram (see Fig. 14). Secure the ca-
bles in place with collars (to connect
the cable to a starter terminal of the
starting engine, it is necessary to re-
move the left-hand side panel of the
dashboard skirt).
NOTE: Tighten finally the coupling
and fastening clamps, and, also, bolts
with all the preheater units fitted and
mated. No water leaks through con-
