Hi all,

 

I have a question in relation to tightening up the k-frame specifically the Control Rod nut, Upper Control Arm Retaining bolts, the Lower Control Arm nut & bolt and the Outrigger nut & bolt.

 

I have just had all the rubbers and bushes replaced in the k-frame, re-installed it, engine & gear box in and now need to torque up all of these nuts and bolts. I was told that the car had to be on the ground so all the suspension components were at operating position before tightening these nuts and bolts.

 

Do I need to use a torque wrench at specific settings for each of these locations, or do people normally go by feel / visual squish on the rubbers?

 

The Max Ellery repair manual I have has torque values for each location, but I don't have a torque wrench and curious if you guys are generally using the actual specified torque values?

 

Cheers,

Brent

I plan to with mine.They are expensive to buy but you could borrow one, mind you ,I bought a cheapy,Supatool ,seems to do the trick ,the workshop manual has most of the torque settings listed.

I torqued mine when I rebuilt my frame.
I went to Bridgestone to have my alignment done. Get the car home and I suss it out, see that they have rooted around with the control rod
nuts (I set them to the specified amount of thread showing on the ends).
I took it back and said 'now do it properly'
I guess the old timers that know how to work these cars are certainly starting to thin out.

If you are going to do your own mechanical work then invest in a good torque wrench.

Manufacturers don't publish the torque specs for various bolts etc just to fill in empty spaces in their workshop manuals.

100 % agree with Dave, torque settings are absolutely necessary & get things even anyway. Any good tool is dearer because it's made to an exact size to torque something correctly. You will pay $250 - $300 for a torque wrench but you'll use it enough anyway. Gary.

You can do it with a normal ring spanner ,just put enough torque on it until your haemorrhoid popps out ,then you know your done!

I used to sell the Warren and Brown torque wrenches when Noah was a boy ,probably made in China now but quality should be ok.

Spend the money, get a good torque wrench. You will use it for years. Got mine at 21 still using it today in my early 50s. You only torque up any pivot type bolts when the car is on its wheels and the suspension is set where it normally sits.
