Instruments, Work Tools And Measuring Devices While Maintenance Services And Repair - Belarus 922.6 Operator's Manual

5.7 Instruments, work tools and measuring devices while maintenance services
and repair
For maintenance services and repair, it is required to use the following instruments,
work tools and measuring devices:
- areometer or density gage for measuring electrolyte density with lower-range value
not more than 1.15 g/cm
accuracy not more than 0,01 g/cm
- multimeter for control of electric chain and electrical equipment running order, with
the opportunity of measuring: constant and alternating voltage – from 1 mV to 1000 V, direct
and alternating current – from 20 mA to 20 A, resistance – from 20 Ohm to 20 megohm.
Measuring inaccuracy of multimeter shall not exceed 30% of the controlled access;
- the device KI-4870 GOSNITI for checking inlet line hermiticity;
- hydraulic manometer with the opportunity of measuring oil pressure and hydraulic
liquids with measurement range from 0 to 50 MPa with a flexible extension rod (tube) and
lugs for coupling with threaded openings. Measuring inaccuracy of the hydraulic manometer
shall not exceed 30% of the controlled access;
- a ruler GOST 7502-98 or tapeline GOST 427-75 for measuring engine cooling liquid
level, belt tension, electrolyte level in combination with a glass tube with diameter from 4 to
10 mm, for adjusting tractor units and systems with measuring inaccuracy of not more than
30% of the controlled access;
- torque wrenches for tightening threaded couplings having measuring inaccuracy
not more than 30% of the controlled access;
- manometer MD-214 GOST 9921-81 for tire inflation pressure control (other devices
having metrological specifications similar to the manometer MD-124 for tire inflation pres-
sure control may be used);
- manometer – 1,6 MPa-1 GOST 2405-80 for pneumatic system pressure control
(other devices having metrological specifications similar to the manometer M-1,6MPa-1 for
pneumatic system pressure control may be used);
- a trammel with a measurement range 150 mm and a division value not more than
0,1 mm according to GOST 166-89 for speed sensor adjustment and rear PTO speed sen-
sor;
- control device 8538-7367-02 for checking and adjustment of conditioner compres-
sor drive belt tension;
- dynamometer DPR-0,1 GOST 13837-79 for forcing control of FLL wheel reducer
fist turn;
- dynamometer-endfloatmeter for measuring steering wheel angle gap;
- a rack-type tool for radiator ribs flattening;
- a set of screw keys GOST 2839-80 for operating with threaded couplings;
- a set of fitter and assembler screwdrivers GOST 17199-88 for operating with
screwed threaded couplings;
- wheel blocks for prevention spontaneous tractor movement while maintenance ser-
vices or repair;
- supporting blocks for machine uplift with lifting capacity not less than 10 tons;
- funnels for filling cooling liquid, oils and other tractor hydraulic liquids;
- tanks for discharge of waste oils and liquids with volume not less than that specified
in column 8 of Table 5.8.1. "The list of tractor "BELARUS-922.6" FLM (fuel and lubrication
materials)".
Instead of the specified instruments, work tools and measuring devices it is possible
to use other instruments, work tools and measuring devices having similar metrological
specifications.
