Swivel rebuild

[AndrewPatrol]

I'm gonna tackle this on w'end and I've heard Nissan doesnt have much in way of different shim sizes for bearing preload so I was wondering if you guys reckon it'd be ok to make shims outa that shim brass from engineering suppliers. Also to measure preload what do you use? Any tricks you's know of would be good too.
Thanks

I wanna know how you know you got the shimming correct... too much or not enough

There should be two different thickness shims in there which worked for me.... I simply used a spring fishing scale wired through the hole the tie rod came from and measured the average of 3 pulls to set preload.

use one of those little fish weighing looking measury devices and test the load, its all in the gregory's manual, its a straight forward job, i just finished mine a month ago, well worth it, pm me if ya need a hand, or mobile 0428 280155

Nissan only carry one size of shim as a replacement--keep track of the shims you remove from yours and re-use them. Make sure you keep the selected size of shims the same on top and bottom bearing to keep the seal centered. A cut-down coke can can sometimes work as a shim

I reused my shims when i did mine. Came up perfect when i put it all back together. Within specs straight up.

Little bit of advice that has suited me in the past, if you preload to around the middle of the spec the preload will strictly need doing again in less than 20000km. If you preload to 1/4 above the top of the spec you may make 100000+km before preloading them again.
I will leave all the pro's and cons of this to decide for yourself, I know I go the extra 1/4 on new swivelhub bearings, after about the first 1000km they are no longer actually above, within a margin of backyard fishscale error anyway .
Also the new wiper seals can add much unwanted resistance that should be factored out.

ok thanks guys, just one more thing - Gregory's says 4.9--14.7 N ( which I gather is Newton) now I would assume fish scales are in Lb. or Kilo's. How do I convert? Hard to make sense of the conversion tables in back of manual.

[Nisspatrol]

i was being stupid when i said fish scales, id say you could pick up a newton weight guage at glenfords or bunnings or maybe even repco,lol. i dont think the fish scales will give you an accurate reading at such a low pressure or weight
cheers

Nisspatrol is right fishscales can be a bit gross but do-able.


1N= 0.2248Lb & 0.1020kg

Im with fnq on this one I reckon the preload as specified is just a little too low, Ive over tightened mine as well and reckon it goes a long way in minimising the shimmer
