There should be a punch mark on the gears you can see to align them. If there isn't you probably need to replace them since they would have to be pretty worn to remove those marks unless you used a grinder to clean them. Even on cars these are sometimes difficult to see at first at times. You can use a piece of white chalk and rub it on the gear face like you where trying to make a wide letter to locate and remark the gear if you need this works sometimes and is easily removed once the gear is installed.

How do you put a timing belt back in time after it broke?


Well, hopefully the valves were not damaged when the belt broke, If no valve damage was done, get the engine/crankshaft to top dead center, line up camshaft sprocket to timing mark and install belt around pulleys, gears, replace water pump if needed, tension belt if no automatic tensioner is used, try to start to see if it runs and hopefully it will. Might be time for an engine if valve damage was done.

Camry timing belt


I am assuming you are referring to a 2.2 liter 5SFE engine. If so camshaft timing mark is dot located on forward face of sprocket mid spoke/or a notch on inboard rim of sprocket. locate mark and paint with white paint. Locate timing mark-small raised dot on plate behind sprocket at approx. one o-clock position paint this white for easy reference. Crank shaft sprocket has small notch on inboard rim. paint white for reference. align cam timing marks, then align crankshaft mark with #0 on timing scale. Adjust tensioner and belt is aligned. I recommend changing idler pulleys and water pump when replacing belt as preventative maintenance. Also inspect shaft oil seals and replace as needed. Performing these services now will save time and money in the future.

How to set ignition timing


Hi Eric, Vehicles fitted with distributors using points (contact breakers) and condensers, which I believe is the case with your vehicle use a dwell angle setting. Initial setting is carried out with a feeler gauge. After replacing points and condenser, turn the engine until the rubbing block on the points is at the highest point against the distributor cam (at the centre of the distributor). Set the gap at 16 thousands of an inch or 0.45 mm. Inspect the front crankshaft fan belt pulley to identify the timing marks. Paint a white mark onto the pointer (fixed to the timing cover) and rotate the engine by hand until you see the timing scale on the crankshaft pulley. mark with white paint at 10 degrees BTDC and align the pulley to the pointer and set the points in the distributor (by releasing the locking bolt of the distributor body) to be at the exact point when it begins to open. Replace the cap and connect a stroboscopic timing light, start the engine and let it idle at normal idle speed and reset the ignition timing to the same marks painted with white paint. Don't forget to take all safety requirements seriously as you will be working on a running engine. Regards John

6g74 timing


I doubt the someone will know the number of belt teeth between one cam to the next(although I have been wrong more than once). That is not the way the cams are set. All I can suggest is that you clean up the pulley, find the timing mark and remark it with some white paint or something alike. If you can't find the timing mark then possibly the best alternative is to buy a new or a good second hand pulley and fit the new part.

I do hope you started this entire process correctly, engine at Top Dead Center compression stroke on number 1 cylinder. As Mark above points out, some serious damage can occur if this is not done correctly. I have seen valves smash through pistons in your model engine, when a bush mechanic attempted to do a timing bet replacement wrongly. Wind the engine over(2 full turns) by hand before you even think of reconnecting the battery.

Do not take it off before you are ready with the new one.
Turn the crankshaft until the engine is at tdc. The key on the pulley should be at the top.
Use a little paint brush and a little paint,and mark a couple of teeth on the camshaft pulley and the belt in between these teeth. if there are any other pulleys using the belt, do the same for them.
Do the same for the crank pulley. Take off the belt, try not to move anything. Count the belt teeth between these two marks and transfere them to the new belt. Now fit the belt in the exact places that the old one came off. Do this very carefully and you should have no problems.

  8. Ensure that the timing belt rotation arrows are still visible. If the marks are worn off, place new rotation marks on the belt. Timing belt alignment marks DOHC subaru-03-25-6472.gif

  9. Turn the crankshaft using a breaker bar and special adapter socket on the crankshaft. Align the timing mark on the crankshaft sprocket (1), left intake sprocket (2), left exhaust sprocket (3), right intake sprocket (4) and right exhaust sprocket (5) with the notches in cylinder block and timing belt cover.
  10. Paint alignment marks on the timing belt at the crankshaft and camshaft sprockets timing marks. CAUTION
    Do not turn the camshaft sprockets with the timing belt removed. The valves heads will contact each other causing the valve stems to bend.
  11. Remove the lower right idler pulley.
  12. Remove the timing belt.
  13. Remove the upper right idler pulley.
  14. Remove the lower left (toothed) idler pulley.
  15. Remove the belt tensioner.
  16. Hold the sprocket and remove the left intake and exhaust camshafts.
  17. Hold the sprocket and remove the right intake and exhaust camshafts.

  7. Align the timing mark on the crankshaft sprocket with the mark on the oil pump cover. Timing belt alignment marks DOHC subaru-03-25-6472.gif

  8. Align the single timing mark on the right exhaust camshaft sprocket with the notch on the timing belt cover.
  9. When the single timing mark on the right exhaust camshaft sprocket is aligned with the notch on the timing belt cover, ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned.
  10. Align the single timing mark on the left exhaust camshaft sprocket with the notch on the timing belt cover by turning the sprocket counter clockwise (viewed from front of engine).
  11. Ensure that the double lines on the intake camshaft and exhaust camshaft sprockets are aligned when the single timing mark on the left exhaust camshaft sprocket is aligned with the notch on the timing belt cover. CAUTION
    • The camshafts can be rotated independently causing the valves heads to contact each other resulting in bent valve stems.
    • When the timing belt is removed the camshafts will turn to the lowest cam lobe position by the force of the valve springs. Before installing the timing belt the 4 camshafts are in the lowest lift position (valves closed).
    • When the camshafts are rotated to install the timing belts, # 2 intake and # 4 exhaust cam lobes of the left camshafts are held to push their corresponding valves down. In this position, these valves are held in the open position. Right camshafts are held so their cam lobes do not push the valves down.
    • The left camshafts must be rotated from the lowest lobe position to the position where the timing belt can be installed at the smallest possible angle in order to prevent intake and exhaust valve contact. Camshaft sprockets rotation subaru-03-25-6473.gif

    • Do not turn the camshafts in the direction shown in the illustration because the valves will open at the same time and contact each other.
    CAUTION
    If the timing belt alignment is off the mark buy more than 3 teeth, the valves and pistons may have contact.

Timing belt needs changed


if I had engine number I could supply details,this is the eng model number that is usually on a tag the size of cig pkt,situated in the firewall or inside of bonnet,others are on door pillar. Failing that strip down to the cambelt,see if you can identify marks on cam,crank sprockets and corresponding marks that they align to on block and head.it's good to paint mark the old belt to those marks so you can transfer those to the new belt,it will make timing easier as you have 2 self checks measures. nb:most belts have engine rotation direction printed on it. make sure that idler,tensioner pulleys arent noisey, if model has a silicone tensioner,these are more difficult to set if tensioner pulley swivels to tension...so to give more precise info i will really need engine spec/model no. IMPORTANT:when belt on,timed and tensioned,turn over in direction of engine crank 2 complete revolutions of crank pulley-that is 4 rotations of cam(s).all marks should be aligned(sprockets and marks)not always paint marks on belt though.if not aligned patience needed more than bent valves.

Timing belt replacement


This is the timing belt replacement procedure to 1999 Vovlo V70
with the B5254s engine

1) Lift power steering and anti-freeze resevoirs slightly and disconnect electrical connector for antifreeze sensor. Then carefully lift both resevoirs and position it on top of the valve cover.

2) Relieve the tension from the serpentine belt tensioner pulley and remove the serpentine belt.

3) Remove the screw holding the plastic timing belt cover and carefully remove the cover.

4) Locate the timing marks on the camshaft pulleys. I highlighted the marks with paint to make them easier to see. I took a dab of white touch up paint and put it on each mark, then waited a minute and then wiped the excess paint carefully, leaving a white line for the mark. The mating marks for the cam gears is on the upper cam gear cover. The marks are rectanular cutouts on the underside of the cover. I was unable to line up the marks unless standing on my head so I extended the marks to the outside of the cover with a white painted dot. This trick made life much easier.

5) Reinstall the timing gear cover.

6) Place a 32mm socket on the crankshaft pulley and connect a breaker bar to the socket. Slowly rotate the engine crankshaft (clockwise) until the camshaft timing marks are aligned with the marks on the gear cover. (I preferred to do this job with the spark plugs installed. I found it easier to keep the engine in time by using the engine compression).

7) Remove the vibration damper by removing the 32mm nut and remove all of the 10mm screws. Carefully pry the pulley from the shaft. There is an alignment pin which allows the pulley to be installed only one way. With the vibration damper removed you can now check the timing alignment with the crankshaft and it's witness mark.

8) Remove the small timing belt shield from the underside of the crankshaft. This shield is helt in place with 2 screws.

9) Loosen the ttiming belt tension and remove the old timing belt.

10) This is a good time to check the waterpump for any signs of wear or leaks. Mine was leaking after 101,000 miles. I also replaced the tensioning pulley and used Volvo OEM parts. (The old Volvo parts lasted 100,000 miles, that is good enough for me).

11) Reverse the procedure for installing the new timing belt.

12) After the belt is installed and properly tensioned, put the breaker bar with the 32mm socket onto the vibration damper and rotate the engine (clockwise) slowly until your timing marks are again aligned. If they are not, remove and reinstall the belt. Don't get frustrated just think of all of the money you have saved by doing this job yourself.
