COVER 4E7499 - Caterpillar

These insulation groups will help keep engine heat away from the operator's compartment. Modifications must be made to the operator's compartment before the insulation groups can be installed. If the machine is not already equipped with the three sided ROPS, a 5T3459 Heat Shield Group (Operator Service) should be installed before the insulation group is installed. See Special Instruction Form SMHS8001 for the correct procedure to install the heat shield group. These insulation groups are installed the same way on each machine. See the instruction that follows for the correct installation procedure. (1) Remove all former insulation from the right side wall. Use a cutting torch or similar tool to remove all brackets from the wall. Install 5T6324 Support (1) with existing hardware. Put 5T6325 Liner (2) in position in support (1) with chamfer (A) toward the front. Fasten the top of liner (2) with 5T6323 Support (3) and the existing hardware. Put floormat (4) [5T6322 - 630 Series; 5T6371 - 620 Series] in position on the floor. These floormats are made to fit all machines in the series shown. Certain sections must be removed from the floor mats, according to the machine they are to be used on. Perforations (areas that can easily be removed) are put in the floormats to help install the floormats in the different machines. Remove only the part of the floormat needed so the floormat will lie flat on the cab floor.(2) Put 5T2077 Step Assembly (5) in position over the edge of floormat (4). Use the holes in step (5) as a guide to make three 10.0 mmØ (.40"Ø) holes through the cab floor. Remove cover (6) and fasten step (5) to the cab floor with three 5K9107 Bolts and 5M2894 Washers. Again install cover (6).
