Swivel pin pre load
By: Namrac Date: October 9, 2015, 10:35 am
---------------------------------------------------------
According to Haynes the pre-load pull on a swivel should be 14 -
16 lbs however I have read somewhere else that that is wrong and
should be 8 - 10 lbs. Can anyone advise who is right please, or
what should it be?

I tend to set them at around 10/12 lb or 14/16 lb with the oils
seal in position. Works for me, fill your relay with oil whilst
you are at it.

There are different pre loads used depending on whether the seal
is fitted or not. It is usual for 2 different poundages to be
quoted depending on this.
8/10 pounds without the swivel seal but with a lubed railco bush
is the correct setting. Remember that is continuous pull after
the initial movement has been made.

Thank you both for your replies. This has answered my question.
Just as an aside before I started to dismantle the swivel, due
to oil leak at axle flange, I checked the pull. The numpty who
did it before had got a 36lb pull and only one shim at the top
bush. No wonder the steering was so heavy.

I wonder if the incorrect shimming was done to stop play in a
worn railco bush ? I tend to modify the kingpin to take a grease
nipple and squirt a bit in now and then. Not really required but
a bit belt n braces instead of relying on the splash oil feed.

You are right to suggest checking the top railco bush. People
often try and take out the movement but just end up hiding it
from inspection only to find the car actually drives worse than
if it was left alone!
For railco bushes though I would suggest oil or at least "one
shot" liquid grease be used. The true bearings love grease cos
there is plenty of room for it to get in. Tight railco bushes
with large touching surface areas much prefer oil.

You may well be correct about a previous owner taking out shims
to take up wear. Judging by some of the other bodges I have come
across now makes sense. The outer race of the bottom roller
bearing was indented with the shape of the rollers. I'm looking
forward to a new driving experience as soon as my new parts
arrive. Still, suppose I had better have a look at the other
side now!

Swivel housing bearing, bushes and preload combined with wheel
bearings make such a huge difference to the way a landy drives
and handles.
Do both swivels and it will feel like a new car!
Indented bottom bearings and over tight railco bushes will give
horrible wandering steering that refuses to self centre
properly.
The preload on the railco bush is not only to remove all slack
from the system but it is also the primary method of steering
dampening. The steering damper was only fitted as options and
later vehicles. Over dampening/over tight railco bishes stops
self centering steering that helps with easy and relaxed
steering on fast roads.

When all is done on swivels. Set the tracking as well it can
really improve the steering. Where are you ? I have some home
made tracking rods if needed.

Thanks spitfiremk1uk and divie for your comments. Sorry to be a
bit slow in replying, have been busy fixing the Landy. Just
finished but yet to road test ready for MOT next week. Will be
doing other swivel soon but is nowhere near as bad as the one
just fixed. It was only an oil leak at the axle flange that
started me off.
Thanks for tracking rods offer but also have some. Replaced
track rods ends whilst at it.
