torquing main bearing caps

Go buy a torque wrench, they’re not that expensive. You’ll use it more than you think. Even a cheap one is better than nothing. My Harbor Freight wrench checked out accurate against my Uncles expensive one. Just store it with cap loose, no load on it. Proper torque values should be easy to find, I’ll look them up if needed, not worth the risk.

 

Please do yourself a favor.

Buy the right torque wrench that you need. Harbor Freight has a torque wrench that goes up to 300 foot pounds that's not expensive.

If you do not torque them tight enough and those bolts come loose your engine is done.

If you over tighten them and you stretch the studs they can break and then your engine is done.

That is one thing that you need to have the exact correct perfect torque with a torque wrench.

 

I see what you mean, torque values are 347-391 ft lbs. I had no idea they were that high. That’s a big torque wrench!! Lol. Good Luck, Maybe you can rent one?

 

EBay used to have a torque wrench that was 600 foot-pounds that was not that expensive. You can use that for your lug nuts also.

If you can't do it hire somebody to crawl underneath and do it.

It's not hard to get a 600 pound torque wrench to click on 400 lb. It is easier to torque it with a regular torque wrench than attempt to go an extra turn or however far with a pipe or whatever.

The method that you are talking about torquing to a certain torque and then going an additional distance is something that is only done if the engineers tell you to do that. Otherwise you need the actual torque wrench.

If I knew somebody torqued my bearings like that, I would not be able to sleep at night and I would be terrified every time I started it and every minute I was going down the road.

Whatever it cost you whatever the aggravation is, it is worth it to know your engine is not going to come apart.

 

Can you use a 1/2 in torque wrench and torque multiplier tool ??

 

The manual I have online doesn’t mention a torqu/ degree method. I torqued flywheel that way, with my big wrench. I forget the lbs. but it was 60 degrees extra after that. On One flat on a 6 sided bolt. Recently saw a Torque wrench with the degrees guage on it also. They make torque multipliers, that are kin to an extension w/ a gear in it. They’re expensive though, but will make a set torque wrench, x 2. Don’t know how accurate they are though.
