Installing TO-20 Head...

Tom Bowman · Oct 27, 2013

I'm not as resourceful as Dylan: I couldn't make my own, so I ordered an extension to torque the pesky bolts on the left side of the TO-20 head:

Worked great! (Hope the $9.99 Harbor Freight torque wrench is good enough for this task.)

I'll probably use this extension a grand total of [i:fff80cbcaf][b:fff80cbcaf]once[/b:fff80cbcaf][/i:fff80cbcaf], but the job would be impossible without this tool, or a homemade version. (I may use it twice, if I'm ambitious enough to re-torque the head after I run the tractor a while.)

If anyone wants to borrow it, just let me know...

Its looking good tom. Gonna be a nice unit.

Tom,
That looks like the answer to the problem, where did you order the extention from?

Let me guess.... $35??
Might be money well spent compare to multiple tries at welding old wrenches together. I have a friend who 'was' a Mac dealer.. quit a steady job to buy into the business.... it ruined his life! So I'll see if another company sells something like that.
Your engine is looking great!

Bob, a MAC Tool salesman calls on my local auto mechanic, and I ordered it through him. (MAC Tools calls it an "XB222A 11/16" Torque Adapter".)

And thanks, Bill. I was getting tired of taking things apart - thought it was time to put things back together for a while.

It was about half that, or just a little over, Tony.

I found a picture of one on the Snap-On website, and that's what I showed to my mechanic. My local Mom and Pop auto parts store couldn't find one, and O'Reilly's just shook their head when I showed them the picture. ("Have you got a part number?")

I know there's also a thread on the board describing how to make a torque adapter/extension with a stubby double box-end wrench and a short piece of hex bar stock, but that would have been tough for me to find, also. (I don't have a welder, so I couldn't make my own out of a socket and an old wrench.)

Thanks! (It's a shame to put all that nasty oil and gas and coolant and fluid back in and get it all dirty and greasy again!

Tony, do a Google search for a "Stanley Proto J5122". A place called "Zoro Tools" has it for $15.82. (I'm sure the YT site wouldn't let me post a link here.)

Just a note. We used these a lot when I was in the Air Force. You will not get the proper torque when you use these adapters. I don't remember the formula, but you have less torque than what you think you have when you use the adapter. Probably not a lot different with such a short adapter, but it will be different.

Thanks for the heads-up, Joe.

I kept the adapter at a 90-degree angle to the torque wrench handle: it is my understanding from this board and elsewhere that this makes a correction unnecessary, as the "effective" length of the torque wrench is almost the same.

(I snugged all of the nuts down first, then torqued to 40, then 60, then 70, all in the correct sequence per the Shop Manual.)
