Removal, check of a condition and installation of camshafts and assembly of yokes
|
|
1. Check axial люфта is made as follows:
a) Establish a camshaft in the engine and fix it covers of bearings;
|
|
b) Fix a tsiferblatny measuring instrument on a head of cylinders, having rested it a plunzher against a shaft end face (see an accompanying illustration); |
c) Having used as the lever a big screw-driver, take away a shaft against the stop back and null a measuring instrument, then push a shaft forward and consider instrument reading;
d) Compare result of measurement to requirements of Specifications;
e) The excessive size axial люфта speaks about wear of a camshaft, or a head. Replace defective components.
2. For check of lateral palpation:
a) Lay the camshaft removed from the engine in two V-shaped prisms, then press a plunzher of a tsiferblatny measuring instrument to a neck of the central bearing and measure palpation size at shaft rotation;
b) Compare results of measurement to requirements of Specifications;
c) At excessive fight the camshaft is subject to replacement. |

THE B18B1 ENGINE (WITHOUT VTEC) Removal
Check
|
|
1. Carefully wipe all components and check them on existence of signs of wear and mechanical damages. Check a condition of working surfaces of yokes and cams of camshafts. Check a condition of axes of yokes. Defective components replace. Do not forget to make sure of passableness маслотоков axes of yokes.
2. Estimate degree of wear of cams of camshafts:
a) Check liftings of cams on existence of deep scratches, задиров, cavities and signs of non-uniform operation;
b) In case of detection of defects replace a shaft, previously having found out and having eliminated a cause of wear. Check impellent oil on existence in it of an abrasive, make sure of passableness маслотоков. Wear of cams is connected with oil pollution more often;
|
|
c) By means of a micrometer measure height of cams (see an accompanying illustration). |
3. Check bearing necks and in bulk and a cover of bearings on existence задиров and signs of non-uniform wear. In case of detection of defects replace a head of cylinders.
4. Measure working gaps in bearings by means of the calibrated wire from Plastigauge set:
a) Wipe covers of bearings and a neck of shaft the pure rags moistened in acetone;
b) Accurately lay shaft in a head of cylinders (without any greasing).
|
|
In the course of procedure performance shaft should not be turned. |
|
|
c) Lay pieces of the calibrated plastic wire from Plastigauge set along bearing necks of a shaft (see an accompanying illustration); |
d) Establish to the place of a cover of bearings, then in stages tighten their fixture with demanded effort (move from the shaft center outside);
e) Give bolts and remove covers;
|
|
f) Measure width of the flattened-out pieces of the calibrated wire on a scale put on packing of a set (see an accompanying illustration); |
g) If results of measurements fall outside the limits an admissible range (see. Specifications), replace worn-out components;
h) Edge of a credit or payphone card scratch out from shaft necks the remains of the flattened-out wire. |
|
Installation
|
|
1. Grease all components with assembly greasing, or pure impellent oil, then establish to the place of assembly of yokes (watch landing marking).
2. Grease cams and necks of camshafts with special assembly greasing, then lay shaft in the bearings (do not mix an inlet shaft with final). Surfaces of covers of the 1st and 6th bearings interfaced to a head grease with anaerobny hermetic. Establish covers, then, moving from the center outside, in stages evenly tighten fixing bolts with demanded effort (see. Specifications).
3. Further installation is made as it should be, the return to an order of dismantle of components. In case of need make adjustment of klapanny gaps (see. Head Routine maintenance).
4. Start the engine on existence of signs of leaks and serviceability of functioning. |

(VTEC) ENGINES B18C1 AND В18С5 Removal
|
|
1. Remove a belt and cogwheels of a drive of GRM (see. Removal, check of a condition and installation of a gas-distributing belt and cogwheels of a drive of GRM).
2. Uncover heads of cylinders (see. Removal and installation of a cover of a head of cylinders).
3. Remove the distributor of ignition and the sensor of fluctuations of a cranked shaft (see. Heads Electric equipment of the engine and Control system of the engine).
4. Weaken lock-nuts and against the stop turn out bolts of adjustment of klapanny gaps.
5. Check covers of bearings of shaft on marking existence in the form of the arrows specifying in the direction to a belt of a drive of GRM. In case of need put the corresponding labels independently by means of a chertilka. Also number covers (with the first on the sixth in the direction from a gas-distributing belt) and mark them on belonging to a concrete shaft (inlet or final).
|
|
The wrong installation of holders of shaft, and also rotation of the last not in that direction can lead to jamming of assemblies. |
|
|
6. Moving from the center outside, in stages (on 1/4 turns for an approach) weaken bolts of fastening of covers, having brought to naught effort developed by klapanny springs (see an illustration – the otdavaniye of bolts should be made in the return shown in a picture an order). Remove plates of holders and a cover of bearings (the interfaced surface of a cover of the 3rd [central] bearing is equipped with the directing pin equipped with a rubber sealing ring – try not to lose fine details). |
7. Take camshafts from a head of cylinders.
|
|
8. Fasten yokes of a drive of each of sets of valves with each other by means of rubber bandages (see an accompanying illustration). |
9. Turn out bolts of fastening of a head of the cylinders, passing through axes of yokes (see. Removal and installation of a head of cylinders). Remove from axes masloraspylitel (see. Removal, check of a condition and installation of camshafts and assembly of yokes).
|
|
10a. Screw in end faces of axes bolts on 12 mm. |
|
|
10b. For heads of bolts serially take axes from a head of cylinders see accompanying illustrations). |
|
|
Check
|
|
1. Check a condition of shaft and yokes (see check paragraphs to the B18B1 ENGINE (WITHOUT VTEC) above).
2. Disassemble sets of yokes and check a condition of components (see. VTEC systems - the general information and check of a condition of components).
|
|
Put components in orders of their belonging to the set – at assembly they should be established strictly on the former places. Having made sure of serviceability of a condition of details, collect sets and fasten them among themselves rubber bandages. |
|
|
Installation
|
|
1. Establish on the regular places of assembly of proof-readers of klapanny gaps (see the previous illustration).
2. Grease all components with assembly greasing, or pure impellent oil. Up to the end weaken screws of adjustment of klapanny gaps. Establish the assemblies of yokes fastened by rubber bandages on the former places, then establish axes of yokes. In each of axes of yokes the nest under landing of a masloraspylitel is provided. If after installation of shaft of a nest appear рассовмещены, correct axes for heads of the boats screwed in their end faces.
3. Put on on masloraspylitel new sealing rings, then establish sprays in a head – do not mix an inlet spray with final (see. VTEC systems - the general information and check of a condition of components). Track, that sprays got to the nests in axes of yokes (at the correct installation sprays should block axes from a provorachivaniye).
4. Grease cams and necks of camshafts with special assembly greasing, then lay shaft in the bearings (do not mix an inlet shaft with final).
|
|
5. Carefully wipe dry rags surfaces of a head contacting to epiploons and establish new epiploons (the equipped springs the parties to a head) (see an accompanying illustration). |
6. Grease surfaces of covers of the 1st and 5th bearings interfaced to a head with anaerobny hermetic.
|
|
7. Establish on covers holders, then, operating in that order (see an accompanying illustration), in stages evenly tighten fixing bolts with demanded effort (see. Specifications). |
8. Further installation is made as it should be, the return to an order of dismantle of components. In case of need make adjustment of klapanny gaps (see. Head Routine maintenance).
9. Start the engine on existence of signs of leaks and serviceability of functioning. |
