I notice I didn't get any lock washer with my Goulds pump and Centripro motor and also the manual only says to put the four nuts and tighten to 13 ft/lbs so I assume this wasn't a mistake.

Also - how would one get a torque wrench in there to get to 13 ft/lbs?

Lock washers aren't important. 13 ft/lbs is not important. Just tighten one side, then the other, like a car tire. As long as you pull it down equally and get the nuts good and snug you are good to go.

I suspect a 200 in-lb ratchet torque wrench with a 1/4 inch drive socket would fit... not that I have done that.

Alternatively, a box wrench could be torqued with a fish scale tugging sideways on the other end.

After some trials, you might "calibrate" your hand to be close enough.

What size are those nuts? Just curious. 3/8?

The nut uses a 1/2" wrench.

The issue is my torque wrench cannot get in there. I have tighten it as much as I can without the lock washers but not feeling good. I tried to "calibrate" my arm on one of the nuts holding my garage door vertical track to 13 ft/lbs but I broke the nut.

It is a tight fit for a 1/2" boxed in wrench. Some people grind down the outside of the wrench to make it fit easier. Need to quit just before you twist off the nuts. :)

OK... tighter space than I was thinking. No ratcheting wrench probably.
