Hello I have put together my engine and I was wondering what is the Torque That I need to use for the engine bolts and for the cams?

Thanks

Look starting on Page 37 at the link below. Ed

The 8 M crank and case bolts are around 16 to 18 ft lbs. The 6M bolts are 70 inch lbs, including the oil pan. The cam bearings are around 105 inch lbs but I only go to about 95. The valve cover bolts are 70 inch lbs.

All of the correct numbers are in the manual available on this site. There should be a page near the back with all of the torque specs. Each section in the disassembly part will also have them.

Here are the torque specs

If you've "put together your engine" and are just now asking about torque "for the engine bolts and cams", that begs the question; what torque spec did you use for the crank cap bolts, the case bolts, the head nuts etc. The torque specs are all in the same appendix tables, as well as scattered through ought the Reassembly section.

If you guessed at the case crank & crank cap bolts especially, you've got bigger worries than engine & cam bolts.

The engine was almost new except that the head was the one that got humidity damage so I replaced to bended valves an did the head job. did honing and new rings as the pistons were almost new.
I did not open the crank.or the case, I did use 31 on the head nut as described in page 286 of the manual that has the chart I attached.
I have set the head nuts at 31 and I am trying to get the cams and the chain in position for the engine timing and then I will torque the cams caps bolts at 13 I guess

If you torque your cam bearings to 13 (ft lbs) you will likely strip a few holes.

Good call. Been there, done that. Those are M6 bolts, and should be ~5-6 ft lbs.

I really do not understand ! Why did you even bother to ask about proper torque settings if you had planned to ignore them and strip the threads on your engine? If you try to torque the cam cap bolts to 13 you WILL strip them! Do yourself a huge favor and look at the link I provided rather than guessing at torque settings. Ed

We use an inch lb. torque wrench probably more than a ft. lb. wrench. We keep a ft. lb. to inch lb. conversion cheat sheet on one of the tool boxes. That puts the in. lb. wrench running in the upper third of it's range most of the time, instead of the lower 20% range on the ft. lb. wrench.

Exactly! Notice the CDI (a Snap-On brand) torque wrench site states the tool should not be used below 20% of its full scale. Ed

I predict the next thread will be how to install a heli coil. (or a Time sert.) (Just kidding!)
