Disassembly and assembly of the piston connecting rod
Disassembly of the piston rod to make in this
1. Remove the circlip holding the piston pin
a boss, poddevaya each of them a small screwdriver.
2. Heat the piston, immersing it in 2-3 minutes in a vessel
with water at 45-75 * C.
3. Vypressuyte piston pin from the piston with a hammer
through a brass frame.
Shatkna assembly with the piston in reverse
the sequence. It is necessary to pay attention
1. In the case of replacing one of the rods must be
matched by weight and size of the hole in the piston pin.
2. Difference in mass between the heaviest and the lightest
rod in the set, placed at the engine, not
should noxtexceed 8 grams
Belonging to a particular rod mass group
marked with paint or a risk to the high tide of his cap.
3. The clearance between the piston pin and connecting rod bushing,
belonging to the same size group (having
the same color coding), check the following:
piston pin should enter smoothly into the hole plugs
under the force of right thumb, as shown
in Fig. 23.
Within this size group planting details
piston pin in the sleeve connecting rod made
with a clearance of 0.0045-0.0095 mm.
4. When assembling the piston connecting rod and piston pin
Always check: coincidence otmnchennyh earlier
number of cylinders on the pistons and rods, the coincidence of the direction
arrows embossed on the bottom of the piston, with projections
on the body and the connecting rod on the lid.
