Cylinder Block Overview

Cylinder Block Overview
Engine blocks 4A-F, 5A-F, 4A-FE, 5A-FE, 7A-FE and 4A-CE have many common design features and most of the one ¬ tipnyh (or even identical) parts. It is primarily concerned with:
• Form and layout of the engine block.
• Construction and installation of crankshaft.
• Construction and the installation of oil pump, drive pinion ¬ adverse events or the rotor of which are located at the toe of crankshaft.
• Ways to seal end of the crankshaft.
• Forms and how to installit back ¬ plate engine.
• Ways to fix the crankshaft of the axial displacement, etc.
This allows the procedure to remove and mustache ¬ SETTING, assembly and disassembly, and control of parts of cylinder blocks of these engines consider the pas ¬ parallel to, pointing out the necessity ¬ Muste the specific characteristics of an engine, or related to the size of parts, or the gauge with adjustable parameters or with personal time ¬ ¬ ties nomenclature hinged fishing or accessions. At the same time, cylinder blocks of these engines have design differences of ¬, which have a significant impact on ¬ tion procedures for their removal from the engine and then install the engine and partially to the procedures of assembly and disassembly procedures for verification and details. In particular ¬ sion:
• The cylinder block and crank mechanism motors 4A-5A-P and P has the smallest details of the number ¬ stvo compared with wasps ¬ tal engines.
• The crank mechanism ¬ IU motor DE 4A-floating piston pin is used, while in other engines - fixed (pressed into the piston connecting rod).
• Different engines have different ¬ private number and a different mapping located ¬ brackets, through which the engine is mounted to the frame.
• For motor 4A-OE is characterized by a slightly different range of outdoor sites and ¬ are some details (the presence of knock sensor, sensor ¬ ka oil pressure high-class plates increase gesture ¬ bone block nozzles for cooling the pistons ¬ Denia, plate-maslous pokoitelya and t . etc.).
• At the same time, engine blocks 4A-FE, 5A-FE and 7A-FE according to the nomenclature of parts is almost completely identical.
In this regard, following leads, separately dyatsya parts of the cylinder and curve voshipno-Rod engine 4A-5A-F and P separately - Engine 4A-OE. Details cylinder block ¬ wood and a crank mechanism for engines 4A-FE, 5A-FE and 7A-FE are considered together. This will eliminate possible misunderstandings in the operations to dismantle the cylinder, as well as his time ¬ Bork, assembling and testing components.
