Friday it broke the prop centre bearing (again) Saturday i fixed it, Sunday it breaks the fan belt, it now sits in the corner of the shed till it learns not to break things
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.
fort you deleted the lpg?hmm.
I did, too lazy to remove the injectorsfort you deleted the lpg?
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 boxThe 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.
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 !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
You missing a pipe there ennners?hmm.
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.My local test station slip portable roller trays under the axle not being tested, a much better idea IMO.
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.I found the roller test info while going through rave to find timing chain procedure.

Also, did you know you're supposed to engage low range when jacking a P38? I didn't.
theres nothing in the owners handbook about selecting low range when jacking to change a tyreWhere 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.
That's why I asked the question Not seen anything in RAVE either.theres nothing in the owners handbook about selecting low range when jacking to change a tyre
Thanks kermie. Like all good Land Rovers they rise up from the ashesAnyone heard how @Rubberknees is getting along? I hope he's doing ok
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.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.

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.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!
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"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.
