seat exhaust side bolt then torque opposite side to 9 ft/lbs
In order to change the torque you will need to tighten the bolt on the exhaust side of the injector to fifty inch pounds. Tighten the drivers' side bolt to nine foot pounds.
I need a specific year... preferably with engine serial number... in order to answer this. Cat never seemed content with the 3126, and always had to change something on it.
The torque specifications for an injector, on a Caterpillar see nine diesel engine, is seven pounds. Over torque in the injector can ruin it.
headbolt torque is : 62 ft/lb cam hold down bolts is : 13 to 20 ft/lb
the longer (new bolts) are to torqued to 48lbs and the shorter ones are to be torqued to 45lbs then turn the bolts an additional 90 degrees the bolts need to be replaced with new one because they are streched when you torque them down
if your cylinder head is made out of aluminum ,i would say to re-torque the head.the bolts holding the head down get lengthened by the head expanding faster than the bolts.
Install the new spark plug and torque it down to 15-21 ft-lb (180-252 in-lb). Install the coil pack and torque the bolts down to 64-95 in-lb (5.33-7.2 ft-lb). Install the new spark plug and torque it down to 15-21 ft-lb (180-252 in-lb). Install the coil pack and torque the bolts down to 64-95 in-lb (5.33-7.2 ft-lb).
Remove valve cover, 2 wires from injector, the fuel line coming from the fuel rail to injector, the lock nut on the head where you just removed the fuel line from, put a nut on injector tube and use a pry bar to pop out the tube, remove the rocker arms (do not mess with adjusting screws) only take out center bolts 10mm, remove 2 8mm hold down bolts on injector, put pry bar under injector hold down and pop intector out. Follow these instructions in order
20nm followed by 240 degrees personally i prefer 20nm then 2x 120 degrees to take the head bolts down nice and easy
The 7th generation Chevrolet Impala with the LA1 engine puts down 210 ft/lbs (280 N.m) of torque. That is as far as I know.
Some torque specs on head bolts require an additional angle torque after the initial foot pounds (or Nm) has been completed. Example, torque the head bolt down to 70 ft lbs then an additional 90 degrees. The torque gauge measures that 90 degrees for you so you can be accurate.
Well, that depends on what you're torquing down.55 ft. lbs. (75 n.m.) for the injector hold down capscrew.130 in. lbs. (15 n.m.) for the rocker cover.35 ft. lbs. (45 n.m.) for the intake manifold.20 ft. lbs. (27 n.m.) for the exhaust manifold.For the head bolts, you'll torque them to 50 ft. lbs. (68 n.m.) for the first step. Then you'd torque them to 100 ft. lbs. (136 n.m.) for the second step. Then you'd rotate the bolts 180 degrees for the third step.If there's something more you're looking for, you'll need to be more specific.
