there are no timing marks for camshafts you need a fiat tool to lock the cams rear of engine but if you mark the cam sprockets carefully before you dismantle you should be ok if not borrow the fiat tools the crankshaft marks are on the front pulley end about @aprox.10oclock position
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.
timing marks ? bottom pulley with crank keyway pointing upwards and cam ? sorry just cannot remember offhand but this is a valve free engine ,with no1 at TDC the inlet and exhaust valves are pointing up and out on the no1 then if i remember rightly the mark on camshaft gear is pointing directly in line with the right side of the head ? or is that the peugeot ,if i had a memory ? Sorry just cannjot remember but a 94 has a distributor on the back of the cam and the rotor arm will pointing at the no1 plug lead on the cap .
fiat punto ,1.2 its a valve free engine so it will not bash the valves ,the bottom pulley mark points at teh top ,you will seea corresponding mark and the cam is top left hand side ,you will see another coresponding mark their for the cam on the ally rocker cover
hi from uk to retime cambelt is as follows = the crank cog has a mark which lines up with corresponding mark on front of engine block mark is approx 12-30 o/clock this is TDC No 1 the the cam cog has a small drilled hole in one of the webs just below the cog teeth ? this hole has to be at 12-o/clock position and then using a small mirror if you look through this hole you will see a vertical notch on the front of block this is theTDC mark for cam you then fit belt anticlockwise from c/shaft to cam then round tensioner then release tensionor to tension belt and then lock it up torque both bolts 20 - 27Nm rotate engine manually 4 complete turns clockwise then recheck marks ok /re align ? then re assemble crank pully bolt torque is 140 -150 Nm may i just inform you? that your engine is what is known as interferance that is to say in event of c/belt failure there is more than likely valves to piston contact however this can also occure too if miss timed belt fitted and engine has tried to start ? a compression test on cylinders will confirm if this has happened or not ? 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
Put the engine at TDC compression stroke , Thats when the valves are both closed on No 1 cyl and the piston is on its compression stroke .then align all cam and crank marks. set dizzy on No 1 cylinder (rotor pointing at #1 plug wire) . rotate engine 2 revolutions and recheck all marks. Fire away
