falcon4250

After a blown head DIY, I've just completed bolting down the head & sprockets of my Ford 1990 EA Falcon. Getting off the timing chain was easy but trying to re-attach it back onto the Cam is too damn HARD!!! Can anyone please shed some light on how to loosen up the timing chain so I can slot it back into the Cam. I tried unlocking the chain tensioner but its still not enough to pull the chain into place of the Cam. Has anyone had this problem?

how did you unlock tensioner,pull it right out and reset it,let me know exactly what you have done.

Hopefully you just unbolted the gear off the cam and left the chain attatched to the gear.....................

yeah usuall i just use some cable ties round the cam gear and just slip it of the cam and let it sit there and bolt everythin back on and it is simple as to get the gear back on without the tensioner in then.

when i 1st got it off I cable tied the chain to the gears. next I released the tensioner unlocked it but did not take out the tensioner as the tensioner retainer was impossible to pull out (tried with two point 90 degrees plier and also standard pliers, still won't budge). I then unbolted the gear off the cam. Rested aside secured, chain still attached to the gears fixed with cable ties. Is there any other notches or pulleys that will allow to loosen the chain abit more?

Chain will go on easer with tensioner removed - be very very careful with that tensioner tough, if it is not reset properly you'll be rebuilding the engine soon!

thanks guys... great help and problem solved. Fiddled a bit more with the tensioner and managed to get tensioner out. Then the chain became so much looser. All fixed and back on the road in no time.

i dont think i set the tensioner correct when i did my headgasket DIY the other day, and it rattled for a bit and the engine worked for 1 day then the next day the timing seems way out and the chains stopped rattling, now it fires into the intake manifold n shit and runs like a dog.. do ya think it might have shifted a cog and how do i reset the chain to the right cog/timing and retention it correctly?/ anyideas,, my car is off the road till i work out how to fix it and i need it!!

HELP????

Its possible that the chain has jumped a tooth. pull the rocker cover off and check the timing marks. With the Harmonic balancer at top dead cantre there should be a mark on the cam gear about 1-2mm above the head if you look at it level from the front. Check the chain, if it is sloppy then that will throw the timing out heaps also.
