Swivel Pin bearings and preload

Hey All,
Going to re do all the seals on my swivel housings soon and I was going to take a good look at the pins/shims/bearings while I was in there. Any pointers on what to look for and/or preload settings. I do not have a guage to pull on the them to get the exact amount of force needed to check preload as stated in the manuall... any other way of doing this... is by feel suicide or good enough?

Also what is the best way to tell if they need changing? Is it nessicary to change the pin and the bearing or is just the bearing OK?

Thanks
steve

You can use a fish scale (things used to weigh fish from a sporting good store) to check the pre-load. Not pretty, but it works.
In most cases you can just reshim to get the pre-load correct. Only in really nasty cases do you need new pins and bearings.

Thats a great idea... any specific brand you reccomend

Really though thanks Mike.

Is it OK to double up the shims or do I have to use one of the correct size?

It takes combos of shims to get it right, not just one. When you take it apart you'll see a number of shims in most cases.
Back in the day before I boughrt the proper tools I used a fish scale from K-mart. Did the job nicely, just didn't let anyone see me using it.

Should be 1.15 - 1.46kg after the initial inertia is overcome.

Fish scale is what I've used for 35 years, works fine. All the manuals say is to use a "spring scale" for non-abs swivels.
I'd put a known weight of the correct amount on the scale to see what it actually reads, in case it reads high or low.

after setting the "pull" I couldnt believe how much slop was in the swivels, the bearings and races looked really good. I am sure I will piss off the power steering pump now.

Tom, I saw you post elsewhere that the spring scale method is only for non-abs setups and to use some tool and a torque wrench for ABS setups. Any harm in using it with an ABS setup, and if not, is the same "1.15 - 1.46kg after the initial inertia is overcome" value still valid?
