Looking for cambelt timing marks/ positions please, Twin cam engine Thanks Kevin

I am not familiar with your engine. When no timing marks are available it means doing the job the old fashioned way and timing the engine with one or more degree discs (or protractors) to the data provided in the engine valve timing diagram or data.

When done correctly it is a very accurate method but it takes a great deal of patience if you aren't familiar with the process. Once you have everything lined up in the correct position you can make timing marks or you might discover no marks were needed - some engines use such things as a spoke or hole in a cam sprocket lining up with a natural feature (such as the top head face). Sometimes there are marks or features on wheels and the other marks are bright links in the timing chain or marks on a new timing belt.

this is your engine
make sure you replace cam seal and timing cover seal

number one on TDC compression
after fitting new timing belt

turn motor by hand clockwise twice and mack sure the belt tension and timing marks are correct

right it a twin cam engine
the cam chain between the two cams
depends what cams are there
do these help

i need the right position of timing marks on twin cam on 3.0 Ford ranger Tdci

Hi, I have pasted instructions below from autozone.com. The instructions call for the use of special tools. You can improvise with alternate tools, but please make sure your timing is right before closing the cover. Please let me know if you have questions, and thanks for using FixYa.

1.9L Diesel Engine
Some special tools are required to perform this procedure properly. A flat bar, VW tool 2065A is used to secure the camshaft in position. A pin, VW tool 2064 is used to fix the pump position while the timing belt is removed. The camshaft and pump work against spring pressure and will move out of position when the timing belt is removed. It is not difficult to find substitutes but do not remove the timing belt without these tools.

WARNING Do not turn the engine or camshaft with the timing belt removed. The pistons will contact the valves and cause internal engine damage.

1. Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s). Remove the camshaft cover and rubber plug at the back end of the camshaft.
2. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to Top Dead Center (TDC) of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
3. With the engine at TDC, insert the bar into the slot at the back of the camshaft. The bar rests on the cylinder head to will hold the camshaft in position.
4. Insert the pin into the injection pump drive sprocket to hold the pump in position.
5. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the sprockets.

To install:

1. Install the new timing belt and adjust the tension so the belt can be twisted 45 degrees at the halfway point between the camshaft and pump sprockets. Tighten the tensioner nut to 33 ft. lbs. (45 Nm).
2. Remove the holding tools.
3. Turn the engine 2 full revolutions to return to TDC for the No. 1 cylinder. Recheck belt tension and timing mark alignment, readjust as required.
4. Install the belt cover and accessory drive belts.
   NOTE If the belt is too tight, there will be a growling noise that rises and falls with engine speed.

hi from uk the cambelt timing marks at TDC are as follows--the crank gear mark is lined up with mark on front of engineblock at approx 10-30 am position the marks are clear as you look ? the cam coghas a dot/pop mark just below teeth this mark is at top ie 12-0'clock position now on cam cog you will also see s hole drilledon the cog web also at 12-o/clock if you look thro this hole (use a mirror ?) the hole lines up to a grooved vertical line at the rear which is on front of engine at this point you fit belt fron crank pully anti clockwise round cam cig then reset tensioner when marks are rechecked with belt fitted/tensioned ? turn engine manually two full rotations clockwise then recheck all mark line up again ? then re assemble ? c/shaft pully bolt tightens to=170-180 Nm hope you notice that the new belt is marked as to its rotation with arrows hope this helps ?best wishes from uk

the cambelt timing marks for clio 1.4 are = the crankshaft cog alignes withmark at 6 o/clock position at TDC No 1 cyl and the cam cog alignes with mark on cyl head at rear of cog at 12 o/clock position belt is fitted anti clockwise from crank then w/pump and then cam cog hope this helps ?

put number one cyl to tdc take out plug put long screwdriver down to check this if you are not sure /check marks on cam pulleys are correct at this point you need to use locking tool to hold pulleys still .if used before you would not have had a problem re fit belt tension turn over 2 times re check marks re check belt tension should be ok now unless valve has got bent moral always lock the camshafs on twin cam engines

hi from uk the cambelt timing marks you req are as follows the crank cog has a dot indent on it and it has to align with same mark on the engine front at approx 12-30 pm position? it is clearly visible then the cam cog you will see a small drilled hole on the cog between the outer toothed and the centre securing bolt ? this hole in cog has to be positioned at top 12 o'clock position then look through this hole and you will see it lines up with a V indent on cyl head this too is clearly visible and advise setting this up b4 fitting c/head for ease ? with these marks set up the engine is at T D C number 1 firing just a note! if you arefitting new belt? it is advisable to replace the tensioner too ! as a kit here in uk belt+tensioner costs £50 if you wish? i can scan and e mail full instructions on cambelt+tensioner strip+renewal proceedure plus detailed diagram of belt set up and relevent marks and tensioner proceedure if you send an e mail address best wishes from n/west uk

There should be marks stamped into the cam and crank gears that need to line up with corresponding marks on the backing plate before you remove the cambelt.

If there are no markings, you need to make your own.

Rotate crank until at TDC (reinstall the crank drivebelt pulley loosely and front cover to do this, then take them off again)

Once at TDC, use correction fluid and mark the crank position twice - once on the crank gear itself and a corresponding mark on the backing plate.

Ditto for the cam gear.

Make sure these marks are aligned when cambelt is replaced, turn engine one full revolution when new cambelt is on to double check marks line up where they should and you're good to go.

Sometimes the cam isn't marked but the crank gear is. In that case line up the crank gear and use the above step to mark the cam gear.

Be precise as the cam gear will most likely move when you take the cambelt off due to tension from the cam on the rockers

Hope this helps :)
