2.9.18. Installation of a head of cylinders

Arrangement of adjusting pins on the block of cylinders (engine M 110)


 PERFORMANCE ORDER

  1. Clear surfaces of a head of cylinders and the block and put new laying on block pins. Do not apply sealing structure.
  1. Install the 1st piston in the provision of VMT and check that VMT tags on distributive to a shaft were combined and that tops of cams of the camshaft of the 1st cylinder were directed up.


Engine M 110

 PERFORMANCE ORDER

  1. Put two wooden whetstones on forward and back speak rapidly laying.
  2. Ask the assistant to insert a chain through an opening in a head of cylinders and you hold the right guide of a chain inside, then lower a head of cylinders on wooden whetstones.
  3. Remove forward whetstone and lower a head of cylinders on a pin, then in the same way lower a back part of a head on a back pin.
  4. Dip head bolts into oil and insert them into place together with washers.
  1. Evenly tighten bolts in three or four receptions the specified moment in the sequence shown in the drawing.
  1. Be convinced of free rotation of both camshafts.
  2. Establish a side guide in a head of cylinders and combine openings then establish the fixing pins by means of the hammer, monitoring the correct provision of a chain.
  3. By means of a piece of a wire lower the directing asterisk in gearing with a chain. Grease an axis of the bearing and insert it into an asterisk by means of the hammer. Remove a wire.
  4. Insert and tighten a cover stopper. Put new laying if it is necessary.
  5. Shift camshafts back and put asterisks and pro-rates; be convinced that the chain reached the correct position.
  1. Insert bolts with expansion plugs into camshafts and tighten them by hand.

  1. Make sure that VMT tag on a damper of tortional fluctuations is combined with an arrow of the index of phases of gas distribution and that VMT tags on distributive gear wheels and a casing of the camshaft are also combined.
  1. Install the top directing core in the bearing of the camshaft and hammer hairpins with the hammer.
  1. Having inserted a metal bar into an opening of a natyazhitel of a distributive chain, drown the directing core to pull a chain, then double-check combination of tags of VMT.
  1. Of early modifications have to be sorted and adjusted by Natyazhiteli. Do not tighten completely a spring tension stopper, be limited to one-two turns. On later designs sort a natyazhitel, then collect him in installation time.
  1. Put to the place of a detail of a natyazhitel and tighten traffic jams and an external ring.
  1. Turn a bent shaft on two whole revolutions and check combination of tags of VMT.
  1. At work serially on everyone distributive to a shaft block an asterisk by means of the metal bar passed in one of openings and tighten a bolt.

Installation of the directing gear wheel (engine M 110)

  1. Put a radiator if it is demanded by a design.
  2. At serial installation of valves turn a bent shaft so that the top of a ledge of a cam was directed up, dip a pusher of a cam into oil and establish it, wringing out the valve down. Hook on a spring for a collar and pull over a cam pusher by means of the screw-driver.
  3. Adjust gaps of valves.
  4. Put a valvate cover with new laying and tighten nuts.
  5. Put a thermostat casing with new laying and tighten bolts.
  6. Put perepuskny a hose from the water pump to a casing of the thermostat and tighten collars.
  7. Establish a tube of return of oil with new laying and tighten a bolt.
  8. Put forward covers with new laying and tighten bolts.
  9. If it is demanded by a design, install the compressor and a hydraulic pump.

 

Engine M 123

 PERFORMANCE ORDER

  1. Ask the assistant to insert a chain through an opening in a head of cylinders up and shift a chain guide up. Then lower a head of cylinders on laying, having centered on an adjusting pin.
  2. Dip head bolts into oil and insert them together with washers.
  3. Evenly tighten bolts in two steps till the specified moments in the sequence shown in the drawing. Be convinced of free rotation of a camshaft. Do not forget about two bolts in an aperture for a chain.
  4. Insert a ventilating tube between the water pump and a head of cylinders, insert and tighten perepuskny bolts with new washers.
  1. Make sure that VMT tag on a damper of tortional fluctuations is combined with an arrow of the index of phases of gas distribution and that VMT tag on distributive to a shaft is combined with a tag on a forward rack.

The arrow showed VMT tags on distributive to a shaft (engine M 123)

  1. Enter a camshaft asterisk into gearing with a chain, having correctly established a segment spline. Then pull it over the camshaft. Insert a bolt and a pro-rate and wrap a bolt by hand.
  2. Pass a metal bar through an opening of a natyazhitel of a chain, press down a guide to pull a chain and again be convinced that tags of VMT are still combined.
  1. Establish a casing of a natyazhitel of a distributive chain, then insert a plunger and tighten a stopper.

Installation of a plunger of a natyazhitel of a distributive chain (engine M 123)

  1. Block a camshaft asterisk by means of the metal bar passed through one of openings then tighten a bolt the specified moment.
  2. On cars with automatic transmission put into place раскос between the right engine mount and a head of cylinders.
  3. Put into place a thermostat casing with new laying and tighten bolts.
  4. Put to the place of perepuskny a hose between the water pump and a casing of the thermostat and tighten collars.
  5. Adjust valvate gaps (see Check and adjustment of gaps in the mechanism of the drive of valves on engines M 123 and M 110).
  6. Put into place a valvate cover with new laying and tighten nuts.
  7. Install auxiliary units.
  8. Slightly grease a tube of the oil probe with sealing paste before pressing it in a pallet casing.
