3.2 Maintenance of tractor components
Table 7 lists maintenance works for the chassis and engine of the “BELARUS-
920.4/952.4” tractors to perform additionally to the maintenance works specified in the table of
scheduled maintenance of the operating manual 900–0000010 OM and Table 14 of the 245S3A-
0000100 OM document, as well as operations that due to differences in the designs of the BELA-
RUS–920.4/952.4 and BELARUS-920.3/952.3 models are to be performed instead of works speci-
fied in the manuals 900–0000010 OM and 245S3A-0000100 OM.
Notes
1. Instead of engine maintenance works 1, 2, 5, 5a, 8, 19a, 20, 21, 22, 31, 34, 38, 39, 40, 51,
53, 54, 55, 56, 57, 58, as listed in the table of scheduled maintenance on pages 109-111 of the op-
erating manual 900-0000010 OM, perform maintenance works as listed in Section 3. MAINTE-
NANCE of the engine operating manual 245S3A-0000100 OM.
2. Because the Belarus-920.4/952.4 tractors are equipped with the air cleaner Donaldson
FPG09-0219, instead of operations on 4, 7, 12, 13, as listed in table 14 of the 245S3A-0000100
OM document, perform the operation 7a (Table 7) of this manual.
3. The engines of the Belarus-920.4/952.4 tractors are equipped with generators with au-
tomatic seasonal voltage adjustment. At that, there is no Winter-Summer seasonal voltage adjust-
ment screw. Consequently, performing MS operations 18, 20, as listed in Table 14 of the 245S3A-
0000100 OM document, is not needed.
4. Because air pressure regulator is used in pneumatic system of improved design on the
tractors “BELARUS-920.4/952.4”, the operation 25 “Filter cleaning of air pressure regulator in
pneumatic system”, specified in the table of scheduled maintenance of the 900–0000010 OM op-
erating manual, is not needed.
