this is my write up on the magna some bits wont apply to your triton
..
'the difference for the trition is the engine is straight
..
the water pump is on the front ..
I have broken an oil pump by not being careful removing the chain guide at the pump the timing chain got caught up
..
so adjusted some bit s in this write up i may have missed something
..
timing chains
Tools
/floor jack/car stands
10 12,14,17,22,34 metric sockets/spanners
scraper blade /pliers
i use a rattle gun to undo chain cogs
permatex sealants
Never Cut the head gasket"
to get the timing chain or cog through
sorry if there are double ups of info
timing mark has to be at TDC
undo crank pully it is on a key way then remove timing cover
the crank pully should be 22mm
the cog rest bolt will need to be undone to get the cog and chain off
remove engine sump 10 mm bolts on base of timing cover
remove rocker cover and undo the two blots inside the head next to the cam cog 12mm holds top of timing cover
if you dont have to take the sump off stuff some rag in the gap so no bolts or rubbish enter the sump
you may have to remove the radiator to make it easier to work on
undo the alternator and air conditioning unit 12 mm undo power steering pump and bracket 14 and 12 mm and any thing else in the way
undo timing cover bolts 12 mm may have different lengths
mark the timing positions dont move the crank or cam
remove the chain guides of the front chain that runs the balance shafts and the oil pump (undo oil pump cog bolt hold the bolt head closest to it to stop it tuning )
watch the oil pump guide
pull off the crankshaft chain cog
undo the top cog support bracket and chain guides 22 mm
refit a new timing cover seal on the way back in
Counter balance set up
one must not assume the chains were fitted properly
so you mark the old chains before removing them
mark the dots and links of both counter balance shafts to ensure they are at the correct position when installing the new chain
the timing chain can be set wrongly also if not bolted to the camshaft
the bright link position is at the dot on the top timing cog which is set at 3 oclock
the crank keyway needs to be at 3 oclock and the top cam is in its locating dowel at 12 oclock ........... number one cyl compression
the two balance shaft sprockets are the same part
the oil pump sprocket is fitted on the reverse side
to the other balance shaft sprocket both sides have dots
make sure after fitting the new chains
the chains and guides touch and run straight
