Timing replacement Toyota Camry 30

Toyota Camry 30 was equipped with 2 types of engines 1mz and 2az. In the first case there was a belt, and in the second - a chain. Consider the option of changing the gas distribution mechanism.

Replacing the timing on the engine 1mz

The frequency of replacing belts and rollers for a Toyota Camry 30 with a 1mz engine according to the regulations is 100 thousand kilometers, but experienced motorists know that the figure needs to be reduced to 80. What is required:

• head set (1/2, 3/4);
• ratchets, at least two: 3/4 with a small and 1/2 with a long handle;
• several 3/4 extensions and preferably a 3/4 cardan;
• wrench;
• hex key 10 mm;
• a set of keys;
• pliers, platypuses, side cutters;
• long flat screwdriver;
• Phillips screwdriver;
• small hammer;
• fork;

In addition to the above set of tools, it is also worth preparing some materials and other devices:

• VD40;
• lithium grease;
• sealant for medium thread;
• nylon clamps;
• self-tapping screws for drywall;
• small mirror;
• lamp;
• antifreeze, which is currently poured into the cooling system;
• impact wrench;
• a set of impact heads;
• if you make extractors yourself - a welding machine;
• drill;
• Angle grinder;

Consider step by step instructions:

Important!!! With each replacement of the gas distribution mechanism, it is necessary to change the pump. It is also recommended to replace the alternator belt.

1. To carry out work, it is necessary to remove the upper suspension arm. Disconnect cables from cruise control.
   
   
2. Remove the alternator belt.
   
   
3. Removing the crankshaft pulley.
   
   
4. Since the crankshaft bolt is very tight, you will have to try to unscrew it. Removal requires a special tool. You will have to take pictures yourself. For the manufacture of the extractor, a pipe segment with an outer diameter of 90 mm and a length of 50 mm is required, as well as a segment of a steel strip 30 × 5 mm about 700 mm long, two M8 x 60 screws.
   
   
5. The desired bolt is tightened very tightly with thread sealant, even an impact wrench with a force of up to 800 Nm is unlikely to help. Options such as a loose pulley with a starter or a blocked flywheel can lead to problems and the need to disassemble the engine. For this, a special tool from Toyota is usually used to prevent slippage of the crankshaft pulley, but if it is not available, you can make a similar tool with your own hands. For the manufacture of the extractor, a pipe segment with an outer diameter of 90 mm and a length of 50 mm is required, as well as a segment of a steel strip 30 × 5 mm about 700 mm long, two M8 x 60 screws.
   
   
6. Using the manufactured tool, unscrew the crankshaft pulley.
   
   
7. After unscrewing the pulley nuts, the pulley itself is unscrewed, again, everything is not so simple, it is unlikely to work with your hands. Do not try to hit the pulley with a hammer or pry it; pulley material is very brittle. With the help of an extractor, you can remove the current from the pulley or chop off its edges, so the tool will have to be slightly modernized, making a full-fledged extractor out of a device for holding the pulley. For termination, a steel strip 30 × 5 mm and 90 mm long is required. Nut and screw M10 x 70 mm. The nut is welded to the strip.
   
   
8. We remove the pulley from the seat.
   
   
9. Having unscrewed the pulley, we disassemble the lower timing protection.
   
   
10. We move the cable box.
    
    
11. Unscrew and remove the top timing belt guard cover.
    
    
12. Remove the alternator bracket.
    
    
13. We put the engine on the stop and remove the engine mount.
    
14. Set timestamps.
    
    
15. Removed the anther from the belt tensioner and measured the reach of the rod. There should be a distance of 10 to 10,8 mm from the tensioner housing to the end of the link. The tensioner must be driven in by sinking the stem. This will require serious efforts, at least 100 kg. This can be done in a vice, but when cocked, the turnbuckle must be in the "rod up" position. Therefore, we slowly push the stem until the holes of the stem and the body coincide, and fix it by inserting a suitable hex key into the hole. Then remove the camshaft sprockets. You will need a special tool to keep the sprockets from spinning, but this can be done with an old timing belt and a suitable piece of wood. To do this, the belt is screwed to the board with self-tapping screws, and the board is cut from the end with a bow to fit the radius of the sprocket.
    
    
16. Drain the coolant.
    
17. We unscrew the fasteners on the water pump and remove it from the seat.
    
18. Clear the block at the bomb site. We install the gasket and the important pump itself.
    
19. Roller change.
    
    
20. Install sprockets and new belt.
    
    

We're rebuilding. Do not add refrigerant to the system.

Timing selection

The original timing belt catalog number is 13568-20020.

Analogues:

• Contitech CT1029.
• SUN W664Y32MM.
• LINSavto 211AL32.

The timing roller bypass number is 1350362030. The timing roller is tensioned under the number 1350520010.

Replacing the timing on the 2AZ engine

Unlike the 1mz, the 2az has a timing chain. Changing it is as difficult as the strap mechanism. The average change interval is 150 km, but tightening should be done every 000–80 km. Consider step by step instructions:

Let's make a replacement:

1. It is recommended to first remove the minute terminal from the battery.
2. Drain engine oil.
   
   
3. Remove the right front wheel.
4. Remove the air filter housing along with the air duct.
5. Remove the alternator belt.
   
   
6. We put emphasis on the engine so that it does not fall off and remove the right bracket.
7. Next, you need to remove the generator and take the connecting cables to the side.
8. Remove the right brake fluid reservoir.
   
   
9. We disassemble the ignition coils.
10. Turn off the crankcase ventilation system.
11. Remove the valve cover.
    
    
12. We mark TTM.
13. Remove the chain tensioner. Warning: Do not start the engine with the tensioner removed.
14. Completely remove the engine mount with clamps.
    
    
15. We have removed the belt of the intelligent auxiliary unit.
    
    
16. Remove the crankshaft pulley.
    
    
17. Remove the timing belt cover.
18. Remove the crankshaft sensor.
19. Remove damper and chain shoe.
20. We dismantle the timing chain.

We assemble with new parts.
