eeac64fe Cleaning and check of the block of cylinders


Telescopic nutromer for measurement of internal diameter




Caps of channels of the cooling system are densely pressed in the block of cylinders.

1. Uncover with inserts, designate from and you store separately.
2. Carefully clear the block of the consolidation remains.
3. Drill block caps (it is almost impossible to turn out them), banish a carving and at assembly establish new caps.
4. Beat out caps of channels of cooling.
5. Get caps flat-nose pliers.
6. At a strong zanryazneniye of the block clean all channels a vapor jet and compressed air (it is recommended to carry out in car service), wash out the block outside detergent. Banish all carving openings, clean and blow compressed air. Dry the block and grease.
7. Banish all carvings of the block of cylinders, having cleared thereby of dirt.
8. Establish covers of radical bearings, tighten bolts by hand.
9. Press new caps without distortions, previously having greased them with Permatex N2 sealant. Wrap new caps of oil channels on the same sealant. Densely tighten caps.


Numbers of dimensional groups of pistons in each of cylinders

1. To a forward part of the engine

2. An orientation tag (it is directed to a forward part of the engine)

3. Tags 1, 2 or 3

1. At detection of outer defects (cracks and chips), repair the block or replace. It is recommended to check existence of internal defects in the block of cylinders for what it is necessary to hand over the block in car service.
2. Check a condition of a surface, a gap between the piston and the cylinder, ovality and conicity of cylinders, having measured diameter in three planes, in the directions parallel and perpendicular block axes. If results differ from standard, then cylinders should be chiseled. After boring of the block pistons and rings of the repair sizes will be necessary.
3. In the absence of a nutromer the gap can be checked special probes about 300 mm long. Insert the piston into the corresponding cylinder and check a piston stroke, laying the probe on the main rubbing surfaces (in the direction of a finger and perpendicular to a finger).
4. The gap is determined by thickness of the probe at which the piston moves in the cylinder under moderate effort. If the piston fails or slides, then the gap is higher norms and the piston it is necessary to replace, and to proshlifovat the cylinder. If the piston jams at position of the probe about NMT and slides at position of the probe about VMT, then conicity of the cylinder exceeds norm. If at turn of the piston in the cylinder with the laid probe the piston jams, then ovality of the cylinder exceeds norm.
5. Standard diameter (dimensional group) of the piston of the engine 1FZ-FE is determined by marking on the piston bottom (groups 1, 2 or 3, see rice. Numbers of dimensional groups of pistons in each of cylinders). Number on the piston has to coincide with number on the block corresponding to this cylinder.
6. If the condition of cylinders accepted wear of the cylinder and a gap between the cylinder and the piston do not exceed the established norms, then cylinders are only required to be otkhonningovat (see subsection
7. For a considerable part of engines pistons and inserts (the crankshaft and a cam-shaft) of the repair sizes are provided. On blocks of cylinders of these engines there are alphabetic references.
