Reverse Discontinuous Signaling Device
ChTZ-Uraltrac / Press-centre / Advice / Reverse Discontinuous Signaling Device

1. INTRODUCTION

The manufacturer recommends to be guided by the main operating manual during the tractor operation, and as for the reverse signaling device complete set - follow the present supplement. The reverse signaling device system is used for all tractor modifications.

The reverse signaling device system is used for all tractor modifications.

2. DESIGNATION

The reverse signaling device system is designed for the tractor safety operation by the cut-and-cover method when developing the mineral deposits. The signaling device sounds in discontinuous manner at the tractor reverse travel.

Important: The signaling system runs continuously at the tractor reverse travel.

3. DESIGN FEATURES

To mount the signaling system on the tractors equipped with the hydraulic mechanical transmission it is required to perform the following operations:

  • remove the floors
  • remove a seat
  • remove the lever 2 connected to the gearshift horizontal rod 4 or 15 for the marsh crawler 64-15РЭ.
  • remove the lever 2 connected to the reverse gear shift horizontal rod 1 or 14 for the marsh crawler 64-15РЭ.
  • remove the spacing rings fit between the gearshift box upper cover and the above-mentioned levers from the shafts.
  • remove the upper cover of the gearshift box КПП-64-12-119СП, remove the switch ВК 415 (the diesel engine start-up lock) having unscrew 19 bolts М10х20 from the above-mentioned cover of the gearshift box;
  • weld on the gearshift box cover the auxiliary bracket, item 2 (Figure 4;

  • or the bracket (for the marsh crawlers, after welding cover the welding points and the brackets with the paint. Place the gearshift box cover back into its position.
  • assemble the parts in reverse order, at that fit the lever 64-12-455 instead the lever 64-12-337 in the case of a marsh crawler and adjust the length of the reverse gear horizontal rod S=(287±1)mm;
  • fit the switch ВК 415 (the start-up lock);
  • check the switch ВК 415 for its operation under voltage not exceeding (24±2)V and under current intensity not more than 1A. At the neutral position of the gear lever the switch should be closed. When I gear is shifted, it should be opened).

INSTALL:

  • the second switch ВК 415(reverse signaling device) by Figure 3;
  • check the switch ВК 415 for its operation at the reverse travel under voltage not exceeding (24±2)V and under current intensity not more than 1A. When forward running is switched on the switch should be closed. When reverse running is switched on the switch should be opened.

Adjust the switch operation with the help of the adjusting washers, item 5 (Figure 3):

  • install the discontinuous signaling device relay on the fastening bracket of the reverse signaling device and of the trailer socket located over the fuel tank;
  • connect the relay to the bundle 50-10-35СП with the help of six-terminal socket ХS 34;
  • carry out the connection to the trailer socket, signaling device, switch ВК415 according to the diagram, Figure 2;
  • connect the wire 201/281 of the above-mentioned bundle to the trailer socket;
  • connect the wire 203 to the wire 3 (of the bundle 10 fit on a tractor);
  • connect the wire 280/281 to the reverse signaling device; connect the wire 210 to the switch ВК 415;
  • fit the ground wire under the closest bolt.

Perform the following operations to install the discontinuous signaling system on the tractors equipped with the mechanical transmission:

From the right-hand switching mechanism 18-12-178СП or 20-12-132СП (for the marsh crawlers):

  • remove plug 700-37-2154, washer 31368, and gaskets 40588 located at the engine side. Shift the lever of range switching and reverse gear at the position of switched-on gear "reverse run";

Notice: if there is a center hole at the end of shaft 18-12-412 (20-12-92 for a marsh crawler) it is necessary to demount the shaft out from the switching mechanism casing, and then weld the hole.

  • fit the plug 700-37-2319, the tab washer 31368, the gaskets 40588 according Figure 1;
  • measure the size Т beginning from the plug end to the end of shaft 18-12-412 (20-12-92 for the marsh crawlers) put into position of shifted gear "reverse running" according to Figure 1;

  • lubricate the threaded part of switch ВК 412 with the sealant Anaterm 8К or Anaterm 8 (Анатерм);
  • screw the switch in the plug hole to the size D (Д) fixed by the formula D=(51-Т)±1mm;
  • lock the switch with the nut 700-30-604 preliminary screwed on the threaded part of the switch;

Note: the terminals of switch ВК 412 should be open at the shifted gear "reverse running".

  • fit the discontinuous signaling device relay on the bracket of reverse signal fastening and trailer socket located over the fuel tank;
  • connect relay to the bundle 50-10-35СП with the help of the six-terminal socket ХS 34;
  • carry out the connection to the trailer socket, signaling device, switch ВК 412 according to the diagram, Figure 2; connect wire 201/281 of the above-mentioned bundle to the socket ОНЦВН (trailer socket);
  • connect the wire 203 to the wire 3 (of the bundle 10 fit on a tractor);
  • connect the wire 280/281 to the reverse signaling device; connect the wire 210 to the switch ВК 412;
  • fit the ground wire under the closest bolt.
