Mr Holder,
Here are those specs and a few other tid bits of info that might come in handy
engine timing: 1342
engine timing deg: gas & duel fuel 8deg btc, LPG only 15deg btc
spark plug gap: gas 0.6mm (.024in), LP 0.4 to 0.5mm (.016 to.020in), dual fuel same as LP
oil pan bolt torque: 10.0Nm, (90 in lbs)
2 studs on oil pan, nut torque is 10.0 Nm, (90 in lbs)
oil drain plug torque 35 to 40Nm (26 to 30 ft lbs)
oil pump bolts 10.0 Nm (90 in lbs)
crankshaft main brg cap bolts 75 Nm (55 ft lbs)
connecting rod cap bolts 40 Nm (30 ft lbs)
flywheel retaining bolts 67.5 Nm (50 ft lbs)
crankshaft pulley nut 170 Nm (125 ft lbs)
counterweight bolts 67.5Nm (50 ft lbs)
camshaft retainer bolts 17Nm (13.0 ft lbs)
when setting timing chain make sure marks on crank and cam are set as follows
-crank mark is pointing at cam gear
-cam mark is pointing away from crank
BOTH marks must be aligned (they will probably look like they are sitting at about 1 oclock.
the links on the timing chain should have marked links which should align with the cam gear mark, the opposite side of chain will align on opposite side of crank gear. (according to the diagram).
the timing chain tensioner bolts should torque at 7.0 Nm (63 in lbs)
there is a note saying that the oil filter should be in position in the oil gallery behind the chain tensioner (apparently there is an oil filter type thing behind the oil tensioner mount)
timing cover bolts torque is 10Nm (90 in lbs)

hope this helps
good luck
