I'm about to change the timing gear on my DOHC ej25. Has anyone got the special tools for holding the cams still while you change the belt? If so, could I borrow them?
You don't really need it, helps, but as long as you rotate it so the alignment marks match up before you take it off, it won't move too far. Just be careful, when it describes the left side of the engine, its the right side when you have the engine in the rear.

I use a couple of vice grips across the 2 gears with a small spacer in between (lightly) :P Timing isn't a problem if you don't hold the gears, just follow the manual to ensure you don't rotate the cam gear incorrectly and touch the inlet and exhaust valves together! Make sure you undo the cam gear bolts prior to removing the timing belt, much easier. Don't forget to load the hyd tensioner and set with a small pin ready for when you reinstall the belt. Have you got a manual, I have the lot on disc if needed.

Just turn the engine over untill the timing marks are set as per the manual, then grip the vice grips on the inside of the 2 timing gears (holding the 2 gears together lightly on each head), this just stops the gears from moving independently when the belts removed.

get the timing marks on the correct locations , mark the said marks with a white pen
you need to remove the hydralic tensioner & when its off place the unit in the vice & ( slowly close it ) & fit a locking pin ( make sure it can be removed when you place it back on the motor
The cams very easly can come off there mark as you are trying to put the belt on thats why its best to mark the pulleys so should they come off the marks you can see this .Its very easy to walk away & not see this happen .
be sure to fit some lock tight to the main pully bolt when reassembly & do it up tight .
Looking for that special lady : PM me for coffee & cake
