York chiller with J body compressors

[Burrah Boy]

Hi all, could someone PLEASE give me the torque settings for the electical terminal posts on the J body recip compressors. I have already broken two from over tightening!
York in the the UK has been taken over by Johnson Controls and getting technical info a no way. I have the manuals for the chiller, but there aren`t any torque settings for any bolts. I am also replacing all the head and oil pump gaskets, so those settings would be a bonus.
Many thanks!

Hi Burrah Boy
These are in LB.FT
Terminal Block 34-40
Terminal Stud (Nut) 20-25
Oil Pump 27-32
Access Cover / Top Head 78-90
Good Luck

You may have been misled?
Because the early J comp studs are steel (copper coated).
The later ones are Copper and it is not easy to tell.
York recommend using a magnet to determine which type you have.
Because of this there are 2 torque settings dependant upon which stud you have.
The above torque is for steel and the copper is 19-22ft lbs

Thanks Grizzly one! The ones I broke are the copper ones, and the new ones they sent seem to be steel!

Sorry, forgot to thank TESLA to!

If you open the attached you will notice there is a gap between the top 2 nuts and the bottom one clamping the terminal post in place.
It is quite common for the fitter to bottom out the 2 top nuts against the bottom one.
Which will cause either the stud to shear or the baseplate to crack.
Therefore it is very important to hold the middle nut in place away from the base nut, whilst tightening.
This is a very common mistake!
You may well be aware of this but someone may benefit from the extra knowledge?

You make me blush SIR!
Sadly growing old is a heavy price to pay in the pursuit of knowledge!

Hopefully we all benefit from our posts...
Even if it's only to admit when we are wrong.

Have a good day!
