Installation of the subframe. As already indicated above, subframes are used for small -sized diesel engines, most often mounted on foundations that do not have tunnels.
If the anchor plate is not laid in the foundation during its structure, but introduced into the well along with the foundation bolt, then to ensure the elasticity of the foundation bolt and the possibility in the subsequent easy replacement in the event of a break in the case of a break, you need to perform the following: weld to the plate with a rectangular opening pipe that is In an mounted state, it would not reach the surface of the foundation by about 100 mm and had an internal diameter of 5-10 mm more than the hypotenuse of the rectangular head of the bolt. Then, on the free end of the pipe, mark the direction of the larger axis of the hole in the plate 2, on the opposite side of the plate to weld the casing 1 with dimensions that allow you to place the head of the new bolt when you break the head of the foundation bolt. At the end of the bolt, the direction of the larger axis of its rectangular head should also be applied.
Then, leading the bolt into the pipe 3, you should pass its head through the hole in the anchor plate, turn it so that the large axis of the head is located perpendicular to the larger axis in the stove and rested on the protrusions available at the end of the stove. Then tighten the bolt until it stops into an anchor plate, pour the oil seal from the strands of a tarred stump at the upper end between the bolt and the pipe and lower the bolt with the pipe into the well.
After all the bolts are lowered into the wells, lift the subframe with a sling, clean it and degrease the lower surfaces, serve to the foundation, lowering it over the foundation and supporting it in this position, the upper ends of the foundation bolts are introduced into the holes in the grinder. Then the nuts are wrapped on bolts and lower the subframe on temporary lining on the foundation or adjusting bolts on supporting tiles, making sure that the foundation bolts are located symmetrically relative to the axes of the wells.
