Front wheel bearings.

[80sprint]

In preparation for an aurgument with the MOT station how do you define a " considerable amount of movement " in wheel bearings which is normal. Even after adjustment there can be rock in the wheel but how much is acceptable. Is there a measurement at the outer face of the wheel as when i have adjusted mine to the specified gap one wheel seems to have more rock than the other.<br>

probaly the same as a tester failing a car due to excessive noise when referring to the zorst , its down to the testers own oppinion.<br>

yea i'd go along with that the trouble is you have testers who aren't even mechs doing mots and realy dont know about tolerances especialy on the older cars<br>
depending how far away from the testing station you are why not adjust all the free play out then mot it and then return it to where it should be i know it's pandering to the tester but it does get you an mot <br>

I agree with George. Just tighten the buggers up for the MOT & loosen them when you get it home. You know it makes sense. <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/images/emoticons/wink.gif ALT=";)"><!--EZCODE EMOTICON END-->

Ditto. My MOT Tester said that he "wouldn't tolerate <!--EZCODE BOLD START--><strong>ANY</strong><!--EZCODE BOLD END--> play in wheel bearings.<br>
<br>
Tighten 'em up - MOT - Loosen 'em off.<br>

In my humble that numbnuts needs to be reported to VOSA. Bloody dangerous.<br>

Looks like i will get my nuts tightened then , but thats another story............

alan, i would report him/ find another tester. firstly over tight bearing are dangerous and the teat manual says something to the effect of 'resonable movement ia allowable' not sure of the exact wording but im sure someone will paste a link showing it.<br>

Note: Some vehicles [especially with ball thrust races) are designed to have a small amount of movement<br>

Not very specific,<br>
but some play is allowed,<br>

There is no noise that i can hear, especially over 45's and stainless exhaust but am i just delaying time on the bearing that has more movement. I think maybe i should replace it anyway but it would just be nice to know some form of measurement but i take it this is not written anywhere.<br>

<br>
How much movement is there,<br>
<br>
Measured at the wheel rim?.

If you've tightened them to the spec in the workshop manual, why not take that along to the tester and show it to him. That should sort out any problems.<br>

The 1977 Official Triumph Dolomite repair and operations manuals contain two differing procedures for adjusting the front wheel bearings.<br>
<br>
In the maintenance section (section 10) it states spin the hub and tighten the nut until slight resistance to hub rotation is felt, then slaken the nut one half a flat and insert a new pin.<br>
<br>
Using this method I have ended up with no play in the bearing but I have found that I have had to take the brake pads out to ensure that they do not touch the brake disc and so cause resistance to hub rotation which cause a wrong set up.<br>
<br>
The other method is given in section 60 and states tighten or slaken the nut as necessary to obtain 0.002 to 0.005 inch end float.<br>
<br>
This is also the method stated in the Haynes manual.<br>
<br>
Using this method results in considerable play and the Haynes manual specifically states that this is the case and is correct.<br>
<br>
To keep my MoT man happy I set the bearings up using the first method to give no play just before the MoT and then slaken then off slightly after the test to give just a bit of play.
