Grill Radiator DZ # 1870

Task : Repair Grill radiator DZ # 1870

first thing i have to do some analyse first  on this Grill radiator

it is made from two plate welded together 8 mm each together make 16 mm thicknesses

and there is a bar plate (5 mm) width x long  750x750 mm  holding the back part of the grill it is welded to the back side of the grill.

i released the bar plate from the grill first using manual oxy acetylene by doing that will make easy  to bend the grill  in to it place.

this is how I've done it what i am used as a tool is :

-manual oxy acetylene with heating tip 

-and a tool called Baji (the one with the orange arrow) 

-hammer 

step by step i heated up point it not directly on the bend spot but the spot before it and using Baji i had hammered it and moving forward until it straight.

i have still got a small bend at the corner I've managed to heat it up and punch it using  hammer .

and it worked.

unfortunately the dz #1870 unit has been hold , so my leader have ordered me to install it back.

so i am not 100% done with it, i don't got a chance  to make a new bar holder at the back yet.

   this is how it look like..
