3.3.8.4. Rods and pistons

GENERAL INFORMATION

Arrangement of joints of piston rings

1. Top disk of an oil scraper ring
2. Top compression ring
3. Lower disk of an oil scraper ring
4. Lower compression ring
5. Dilator of an oil scraper ring
6. Dredging (appeal to a forward part of the engine)

Installation

PERFORMANCE ORDER
1. Before installation of pistons assembled with rods the surface of the cylinder has to be absolutely pure, has to be chamfered edges of cylinders, and the crankshaft is installed in the block of cylinders.
2. Sort a rod of the 1st cylinder. Wipe a back surface of a new top connecting rod and lay it in the place in a rod. Make sure that the ledge on an insert came into selection in a rod and lubricant openings coincided. Not to grease an insert. Similarly establish the lower insert in a rod cover.
3. Place joints of piston rings according to the scheme (see rice. Arrangement of joints of piston rings).
4. Dress hoses on bolts of rods. Oil pistons and rings pure for the engine, squeeze rings adaptation, having left the acting site of the piston.
5. Turn the crankshaft to NMT in the first cylinder, oil cylinder walls for the engine.
6. Orient the piston so that dredging was turned towards a forward part of the engine.
7. Carefully enter the lower part of the piston with a rod into the first cylinder against the stop of adaptation in the block of cylinders. Slightly knock on the upper edge of a mandrel for uniform contact with the plane of the block of cylinders.
8. Enter the piston into the cylinder, carefully tapping with the wooden handle of the hammer on the piston bottom. Big effort not to apply. If resistance is felt, then immediately stop sideways and remove the cause of jamming.
9. Attract a rod to a neck of the crankshaft and check a gap in the conrod bearing. The procedure of check differs in nothing from the procedure for radical bearings (see subsection 3.3.7.8). Rotation of the crankshaft or the slightest hit of oil on inserts at measurements are not allowed.
10. Tighten nuts of a cover of a rod with the set moment a face head with thin walls (to exclude jamming of a head between a nut and a cover of a rod. If the gap does not meet standard, then be convinced of lack of lubricant and dirt and again check diameter of a neck and correctness of selection of a connecting rod.

Final assembly

PERFORMANCE ORDER
1. Carefully remove the caliber remains, grease inserts and a conrod neck of the crankshaft, establish a cover and evenly in 3 stages tighten nuts with the set moment.
2. Repeat these operations for other rods. Check freedom of rotation collected Kalevala.
3. After final installation of pistons with rods, check freedom of rotation of the crankshaft.
4. Check an axial side play of a rod (see subsection 3.3.7.7). Keep in mind that after installation of new rods the side play can be less norm and grinding of rods will be required.
5. Collect and install the engine, being guided by appropriate sections.
