I'm in the process of changing the front wheel bearings on my ecr33 Skyline and I notice in the manual there is no torque spec for the big 32 mm nut that holds the spindle / hub assembly onto the knuckle . In fact , in the FSM I don't even see the that specific bolt in the part breakdown. I notice that the nut was punched on the edges to secure on the stud it threads on so i'm not sure if I just seat it properly and punch it or if it has to be set to a specific torque.

the picture below will give you a Idea of the Nut i'm talking about if my explanation is unclear. i know its a rear hub and not from a skyline but its to give you a idea of the nut i'm talking about

Any help would be greatly appreciated , Thanks !

There's not really a torque setting.  These things are done up to a "feel".

Thanks for the reply GTSBoy - I ended up calling a buddy that looked in a USDM shop manual on his computer at work. Since its the same bearing as a 300z I assume its the same torque spec. The manual listed a torque of 200Ft/lbs so I wont take any change and follow the FSM as both have same bearing and setup according to the part breakdown

Haha.  I just realised you were talking about the nut on the back!

 

Your other option for this sort of info is the R32 GTR manual which has been downloadable from your uncle Torrence for many years, if you don't already have it.

yeah but this is for a 2wd not 4wd as the 4wd bearing is held by the nut at the end of the driveshaft, so GTR manual not helpful

When you can't find a specific torque work from the diameter of the bolt/stud it is going on, 200ft/lb is about right for an M18 bolt assuming 8.8 strength

      Neostead, I'm looking to have a custom surround done that also has a slot for a fog light. Would you be willing to create a 3d model I can buy or create and ship me the part or even provide/sell the current model for me to modify? Cheers

      Did some maintenance on the MX5, did the engine oil and filter which was uneventful, then I drained the coolant to put in the new reservoir and a thermostat, reservoir took 5 minutes  The thermostat, well that took.........3 bloody hours, what a job, the issue was the 3 bolts holding it on, one was easy, 2 were hidden and required a few 1/4 drive extensions, 1 more than I had, and a 1/4 swivel, which I also didn't have, and a good amount of playing contortionist  Getting the 2 unseen bolts back on was a time consuming nervous nightmare, as I couldn't see where they went there was alot of stabbing and hoping for the best, trying to line up a 8 mm bolt straight, which you cannot actually see or get a hand in there, with a 1/4 swivel in the mix was a nightmare Anyways, it's done now, all burped out, and run up to temp a few times, happily no leaks thank Jebus After the thermostat fiasco I decided I need a few mental health days away from tools before doing the rest of the servicing on it As for the Dunnydoore, it had the aircon regassed and it has a clean bill of health, thinking about taking it out on Monday for a cruise down the coast to look at some houses if weather permits

      In other important race car news, instead of fixing the race car I changed the crank seals on the chainsaw, because wood burner Some damn tight (and lock tighted) m6 head bolts Who knew plastic crank cases were a thing! Quick tip, don't trust the youtube videos that say you can pull the old seals out with the head on in a husky 440e...not true, their crank seal tucks in behind the cover both sides. I'm not sure I'm a psychopath, but these things are damn loud....hope I can put all the bits back in the right place    Happily, it is now back to turning fallen trees into a combination of firewood logs and wood chips....just need a clear day to get into it properly

      Don't forget to make sure the tank is full to the brim before you try to replace the fuel pump too, that is an essential step.
