REMOVAL

 PERFORMANCE ORDER

1. Uncover a head of cylinders (see the Section Removal and installation of a cover of a head of cylinders).
2. Bring the piston of the first cylinder into the provision of VMT (see the Section Reduction of the Piston of the First Cylinder in the provision of the top dead point (TDP)), take off a gas-distributing belt (see the Section Removal, check of a state and installation of a gas-distributing belt and cogwheels of the GRM drive).

3. Weaken on 1/4 turns bolts of covers of bearings of the camshaft (for easing of the effort developed by valvate springs), - act as it should be, the return shown on an illustration.

4. Take assembly of yokes with axes from a head of cylinders. Bolts of covers of bearings of the camshaft will not allow assembly to be scattered.

CHECK

 PERFORMANCE ORDER

1. Having removed assembly of yokes, it will be reasonable to investigate it for the purpose of more detailed studying of a condition of components. Turn out fixing bolts and remove from axes of a yoke, a spring and a cover of bearings. It will be reasonable to mark previously the provision of axes in relation to covers of bearings.

On the engines equipped with the VTEC system it will be reasonable to fasten yokes of primary and secondary inlet valves with rubber bandages. Try to put the removed components as their installation as at assembly they have to be put strictly on the former places.

2. Carefully clear components and check them for existence of signs of wear and damages. Estimate a condition of the surfaces of yokes contacting to the camshaft. Check for existence of zadir and signs of excessive wear of a surface of landing of yokes on axes, and also walls of landing openings of yokes. Defective components are subject to replacement. Make sure also of passability of maslotok in axes.

On the VTEC models of a yoke are equipped with roller tips. Estimate degree of wear and freedom of rotation of rollers.

3. On the engines equipped with the VTEC system take from the landing nests in a head of cylinders proofreaders of valvate gaps and carefully clean them. Fingers check freedom of the course of plungers.

INSTALLATION

 PERFORMANCE ORDER

1. Oil all components pure motive and establish them on the regular places on axes of yokes.

Pay attention to the marking distinguishing left-side components from right-hand.

2. Grease cams and necks of the camshaft with special adjusting lubricant. Apply a thin layer of anaerobic sealant then establish assembly of yokes on the regular place on the surfaces of covers of the first and sixth bearings of the camshaft interfaced to a head of cylinders.

3. In strictly certain order in stages tighten bolts of fastening of covers of the camshaft with the required effort.

4. Installation of the remained components is made as it should be, the return to an order of their dismantle.
5. In conclusion do not forget to make adjustment of valvate gaps (if in it there is a need) (see the Head Nastroyki and routine maintenance).
6. Start the engine and check it for existence of signs of leak of oil and serviceability of functioning.
