Power steering pump torques

Is there a torque spec for the bolt that secures the pressure line to the power steering pump (red arrow)? Also I assume the sensor connector (green arrow) does not have one because it is not really a bolt compatible with torque wrenches.

I could only find the spec for the two bolts that attach the pump to the block but not this. Thanks in advance.

 

I believe this is what you're after:

 

@burrito782 -- thanks, I wonder how they think you could measure the torque on the connector. You can't fit a socket over it.

 

I can tell you my original one was tightend way more than 38 ftlbs.... I had to use a 1/2 drive with a jack handle for a cheater bar to break that sucker loose. It was so tight the threads on it had to be cleaned up to get it to go into the new pump.

 

Yes, you can. Or you can use a crow foot. Though I’m guessing you haven’t got one if you don’t have deep sockets

 

I googled it, makes sense.

 

Spark plug tight is good enough on the switch.
It’s o-ring sealed.


If you are really going to torque it.
Turn the crows foot 90 degrees to keep the specs true.

 

you can fit a socket over a spark plug and then torque to spec though i understand there is no way around using an extension bar, which reduces the accuracy of the torque wrench

 

Extension don’t reduce accuracy.
That’s a myth.

As long as the distance from the drive stays the same. Accuracy is the same.

 

as many bolts require extension on 1GR-FE, being wrong about that is music to my ears

 

Fair enough.
With as many 6mm bolts that are used on these trucks. I don’t use the wrench unless it’s a critical fastener. Go by feel.

 

6 mm ?? i have literally never seen one. the smallest is 10

 

Thread diameter.

 

oh no, i meant the bolt head/socket

 

10mm bolt head is usually 6mm diameter.

 

Actually, I was able to fit a long 19 mm socket over the sensor and torque it to 15 ft/lbs

 

See my quote below, easier to copy/pasta.

Now with that said, if you're using something like this to get on top of the bolt you're trying to torque then there's no need to use the above formula because you are effectively using the same pivot point on the torque wrench. I'd like to caveat on to what I just said, extensions like what I just listed can be subjected to spring twist force if you are using an undersized extension and subjected to heavy torque, think using a 1/4" socket 24" extension and slapping down like 75ft lbs of torque, you might try using a 3/8 or 1/2 drive extension for something like that. If this is a concern to you, there are products that are rated specifically for using extensions in torque settings. Just be aware that using extensions may alter the set torque due to that spring twist. Where the above formula does come into play is if you are using something like this to access the head of your bolt since you are adding a length to your torque wrench. Hope this helps.

“Spring twist” doesn’t affect torque.
Not on almost all automotive applications, it doesn’t.

If the wrench clicks, desired torque was reached at the fastener. Unless the wrench is bad.

Torque in = torque out.

 

That's basically what I was trying to say. It's negligible at best. However, if you're extending the length of the wrench through the use of a dogbone, then you'll want to use the formula I listed above.

What is the torque spec for the two mounting bolts for the power steering pump to the block @foampile? I drive a 2018 Tacoma SR5. Thank you for the help.
