How many lbs of torque on the mounting bolts on the starter housing????

 

Here is a chart that shows all the torque specs for different sizes of grade 5 bolts. Use the column #6 for dry thread settings which is what you usually do. Most vehicles use grade 5 bolts...unless the manufacturer specifies otherwise I'd use the grade 5 settings even if you replace the bolts with a grade 8 bolt.

This still leaves you with the question of what size your bolts are. I've seen people buy an assortment of nuts and lable them when they buy them or you can get a cheap dial caliper and use it to measure the bolts. I'd have to double check but I think a 1/2" bolt measures 1/2" in the thread valleys?

If you can't get a torque wrench on the bolts then use the torque wrench on a bolt you can reach...then feel it by hand to see how hard you have to push/pull to make it turn slightly. Then use that feel to tighten the hard to reach bolts. Remember that a swivel will take more torque to turn so you have to push/pull tighter to get the same torque reading depending on the angle of the swivel.

ok the book says secure the starter bolts to 32 ft. lbs(43Nm) I dont wanna mess up the threads like i did on the tranny. So I would torque to 32 foot pounds?

 

1 Lb-Ft = 1.35582 Nm, so 32 ft =@ 43.39nm.

Last time you overlooked inch lbs and read ft lbs. It was apparent because the Nm value d/n equal the ft lb value, but it did equal 1/12 of it (ft vs inch lb difference). In this case, the vaules are equal; also the blots are much bigger, and you are turning the bolts into the engine block (steel) not alluminuim (tranny).

It looks like Pushnfords forgot to add the attachment for general torque spec. I looked up the spec for starter mount bolts on my 96 5.2 and its more (50 ft lbs). For a 96 diesel, 32 ft is correct. Which do you have?

PS, I show one mounting nut (not only mounting bolts) on the gas engine. Its value is less; 20 ft lbs (27 N-m). This is not lead/terminal nuts that attach the wires. The values for those are:

120 INCH lbs (14 N-m) for the battery lead terminal nut and 22 INCH lbs (2.5 N-m)for the solinoid terminal nuton the gas engine.

90 INCH lbs (10 N-m) for the battery lead nut, 55 INCH lbs (6 N-m) for the solinoid lead nut, on the diesel engine.

Remember, ft lbs are 1/12 of inch lbs so 120 inch lbs are @ 10 ft lbs.

Notice above 20 ft lbs are 27 Nm and 120 inch lbs (@ 10 ft lbs) are 14Nm. That isabout half of the 27NM which would be correct, 10 is half of 20.
