Alcan nut sizes for tightening updated

[Galway Girl]

Just had Alcan redo our Hull 505 with new springs. Here's a video showing how they make the springs...starting at 1:14 mark for about 2 minutes.

After a spring replacement with an Alcan 4spring pack we need to retorque nuts.

Q)  What size sockets are needed to tighten all the nuts after a spring replacement from Alcan?  
 

A) Here is the detail from Alcan:

You need a 22mm or 7/8” socket and 150ft-lb torque wrench for Ubolts and inside shackle bolts

Use a 21mm or 13/16” as backer wrench or standard depth socket on nuts outside of shackle.

 

Mileages:

Retorque u-bolts & shackles at 50mi,     100 mi and 500miles after installation, then yearly check.

Torques Values: 

 U-Bolts   90 ft-lbs

Shackles:  65 ft-lb

(Note - use 21mm or 13/16” backing wrench on outside of shackles)

Also check lug nuts to wheel specs at each interval as well.

7/8 for both the U bolts and the shackle bolts. Both U bolts and shackle bolts are 9/16 diameter so the wrench size for this standard nut size is 7/8. You will need a deep well socket for the U bolt nuts. I have a deep well 7/8 socket for my truck wheels so this worked perfectly.

Craig, besides the 7/8” deep socket Ken mentioned, a 13/16” socket might be needed to hold the front side of the shackle wet-bolts if they were to slip. A deep-well socket may be needed here too to fit over the Zerks.

The other day, the bolt holding the equalizer to the center hanger was spinning on mine. Using 13/16” socket and short extension, the breaker bar hanging between the tires, I was then able to tighten/torque while the tire held the bar in front! 😎 (thought at first, I would need to ask Chris to hold the front side).

Nice for Ken, 7/8” works for all! I need 15/16” for Dodge wheels and 3/4” for Oliver wheels. I bring all sizes from 1/2” to 15/16” in deep-well 1/2” drive impact sockets and the same sizes in short sockets 3/8” drive. Also have 1/2” to 3/8” and 3/8” to 1/2” drive adapters to use any socket in any ratchet, ratchets in all sizes, and a 1/2” breaker bar that fits into a 2 ft cheater bar!

I want to be able to make repairs like replace a water pump/serpentine belt on the road, change Nev-R Lube bearings (see thread on that with tools listed), most auto repairs.

That should do it! 🤣

I’m going to try and get all the right sockets ahead of time. 

 

Thanks

This may be of help. You will definitely need deep well sockets for the Ubolts.
