so, I thought I'd have a go at cracking this nut!

this came out easily.

sunken circlip ends? Naah... Little trick..
IMG_20220711_092731.jpg
drill a hole adjacent to the circlip and a punch through the hole and up it popped!

bingo.

it touched 17tonne before it broke free.. (I actually stopped looking and turned my back for the final break away.)

bearing in mind :rolleyes: this bearing was caught before it was overheated so some may take a lot more to free em off! Hub saved and carrier for @RisforRacingnotReverse when his start:cool:

his turn after a careful turn with a small cutting disk and a sharp blow with a chisel it gave up!

it does seem an inner casing may have spun at some point in its working life and without knowing the original measurements of the hubs dimensions I'm doubtful of it being used again :( shame :rolleyes:

The rollers are indeed contra rotating, what I do not understand is how the brakes can be properly tested in that way. The stress when the brakes are applied must be enormous.

I guess the brakes should work as well in reverse as forwards. Any difference in braking efficiency - which is what you are testing - will be taken up by the diff but it does that anyway.
 
The brake roller computer works out the drag forward and backward and gives an average so front and rear prop never turns same with hand brake so dont worry about it my 04 l322 was tested like this for 5 years I had it and the 08 i have now just passed its test done that way with no issues.
so in an ideal perfect working system its fine, but if one caliper stops working it lets the one wheel turn whilst one is stopped that turning motion must pass back up the prop into the transfer box causing either front prop to turn or gear box

The rollers are motor driven so never stop, if one wheel isnt braking the computer knows this and keeps that wheel turning and register low effort on that wheel while other wheel will show a reading not the best explanation I know if one wheel does lock up the rollers keep going and the tester should release the brakes. These newer brake rollers also weight the car and work out braking force against weight, if the car is light enough ( yes like 2 wheel drive) the rollers will throw the car out the of them, if the test place has shaker plates for checking ball joints ect them things are evil, seen wishbones flexing under the force of them !
 
My local test station slip portable roller trays under the axle not being tested, a much better idea IMO.
I found the roller test info while going through rave to find timing chain procedure. You have to disable ABS and TC. If you use a single axle tester you need to remove the static propshaft. So you can test the brakes but you'll get ABS faults on the dash. That needs testing by conducting a road test.

Also, did you know you're supposed to engage low range when jacking a P38? I didn't.

Never seen any of that stuff done with the ABS/prop and the MOT testing rollers are not a dynamometer, they are electrically powered to turn the wheels with the gears in neutral.
Where did you read that a P38 needs to be in Low Range when jacking? The only special instruction I have seen is to leave the tailgate open to disable the EAS.

theres nothing in the owners handbook about selecting low range when jacking to change a tyre

The lower part of the table says the gearbox and tbox are to be in neutral, which means they are referring the powered brake testers so it seems LR consider them to be the same thing.

In RAVE.

Half my village seems to have it. Many for the second or third time. Bloody rife and we have a big party planned for 2 weeks time, just as it will peak!
This is my first time. I was suspicious over the weekend because I felt terrible, but LFTs kept coming back negative. Was only this morning it ping positive and I feel like I am over the hump, beyond a tight chest.

Guys at work have had it 5 or 6 times and they have a super spreader event planned for this evening. So can't wait for no one to be at work in a few weeks time.

Good luck avoiding it. :eek:

I cannot see any sense in selecting low range when jacking. I think that must be an old version of RAVE or user manual, mine says "select low or high range"
