Second Plastic

The thickness of the polyethylene film at face value: for bearing weight w3 kg – 100 microns, bearing a mass of Z. It is not something Gary Kelly would like to discuss. .. 8 kg – 150 microns. Pasting an open interface is a polyethylene film with adhesive layer. I tapered split bearing diameter 200 mm with a mass greater than 5 kg are wrapped separately outer ring and inner rings of blocks. Allowed joint wrapping split bearing provided laying paper or film between the block and the outer ring. Individual parts, canned lanolin emulsion, packaged individually or in a group of inhibited and then waxed paper or plastic bag with a embedded in a inhibited paper.

Individual parts, canned or inhibited IBAC LB oil, packaged in plastic wrap, without pre-wrapping of the initialed paper. Bearings with diameters from 200 to 300 mm mass 8 kg packed in polyethylene bags and then into a package of PVC film with shelf life of 6 years. Allowed to use one packet of polyethylene thickness of 200 microns at face value. When packed in polyethylene excess air bags are removed by suction or otzhatiem. Allowed an additional package to the second plastic bag with a bag of silica gel between the bags. Bearings, weighing more than W kg packed by direct bearing winding strips of waxed paper capacitors and plastic film through the holes. Permitted other methods and materials inside the package to ensure the safety of bearings and protect them from corrosion. Packing boxes and bearings in packs of cardboard. General packaging requirements of bearings in the box and packs are installed GOST 520-89 and are as follows: bearings with outer diameter of 300 mm, weighing up to 8kg of accuracy classes 5,4, 2, and bearing accuracy classes and six special purpose must be packed in boxes or bundles (TU 37.006.096-89) instrument bearings with outer diameter of 30 mm of accuracy classes are packaged in boxes, with the bearing accuracy classes 6, 5, 4, 2, T pre-packaged in plastic tubes or plastic bags.

Engine Cylinder Block Kamaz

On automobiles KAMAZ installed eight V-shaped petrol model 740. The cylinder block is a rigid monoblock V-shaped structure. It is cast from gray iron doped as a single unit with the upper part crankcase. Block bore along with covers of indigenous poles, so they are interchangeable, and they are placed in a strictly fixed position. Crankcase part is connected with the root cap bolts bearing cross-bracing, forming a rugged box-section.

To increase the longitudinal stiffness of the outer wall of the block have a curved shape. Lug bolts cylinder heads are evenly distributed around tides of each cylinder transverse walls, forming a water jacket. Due to the fact that at one crank crankshaft journals are two connecting rods, the left cylinder bank offset from the right forward at 29, 5 mm. Cylinder liners of wet type, easily removable, for KAMAZ vehicles manufactured from special cast iron by centrifugal casting, in order to improve hardness and durability are the bulk quenching. Microgeometry mirror shells is a rare grid cavities at an angle to the axis of the sleeve. This treatment helps keep the oil in the depressions and a better running-in ability sleeve. Cylinder head for each individual cylinder, as well as many other parts KAMAZ, made of aluminum alloy, aluminum and have a shirt that communicate with the face of the block. Junction block and cylinder head gasket.

Overflow hole water and oil, as well as head of the contour of a molded rubber gasket sealed. Gas joint – a steel liner, which is deformed steel support ring, pressed on the underside of the head. At the top plane head area is located under the counter rocker valve gear. Cast iron seats and metal valve guide bushings bore after mounting in the head. Valve gear link head aluminum lid is closed, which is placed under seal. Inlet and outlet channels are located on opposite sides of the head. Has a tangential inlet port profile provides swirling motion of air in the cylinder, it is necessary to accelerate the combustion of fuel injected into the engine KAMAZ trucks. The nest is located under the nozzle outlet side at an angle to the cylinder axis.

Property Manageability

If you can afford a big bus with a speed rating (they are 10-15% more expensive) – I would recommend this option active drivers drive. However, do not skimp on the index of the rate, lowering it below the recommended (especially when buying cheap winter tires) – known as the 'better safe than sorry …'. Summer features. This is a series of consumer quality tires that are more fully realized when used in tire temperatures above + 7 C. Adhesion to dry. This indicator measures the brake or coupling properties of the tires when driving on dry hard surface. Influence on this parameter: the mixture of rubber, the contact area of rubber on the road (Closed design), the stability of the contact form (depending on the design of tires).

The best way to evaluate this option – to study the results of objective tests of braking tires, published by reputable journals. Traction in the wet. Determined by the efficiency of braking in the wet solid surfaces. Depends on the presence in the tread compound of the special additives that additional edge strength (blades), the stability of the form contact patch. Objective tests – the best way to evaluate this option.

Manageability – this property is set to follow the bus driver of the trajectory of the car, informative steering reactions. At this setting will affect form the tread pattern rigidity of its central area and the shoulder elements of rubber. For motion in cornering stability is particularly important form of the contact, depending on the design of the tire carcass and the presence of reinforcing layers-breakers.
