yu are talking complete bollox!
I have owned a Gaylander - KV6 :puke: and I am neither taking the ****, or trying to give advice on this thread, just asking for some feedback. Others who know me far better than you , know my involvement on Gaylander "issues" and the discussions over the last few years. So crawl back to yo hole :mad:
If a VCU turns by hand, then it is blatently obvious that it isnt seized, but it can fail in other ways, which you seem to have ignored. Several peeps on this forum have had them fail in a "non seized" way.
I have never said that the validity of my posts is correlated to the number of posts. I have, on rare occasions been mistaken, never wrong :p.
If you dont wish to contribute, then fook orf.
Valid figures may be of use, but if no-one posts any then it is a wasted exercise.
Suffice it, to say that others with more knowledge than you, thought it was a good idea.

At the end of the day - you do what you want to do - and live with the results :rolleyes:
 
Whatever m8. You obviously know everything about everything held together with nuts and bolts.


As for not wishing to contribute, Read my 1st post again. I was offering a solution to a problem you pointed out in the first post. A solution that is simple. The point io was trying to make is that torque tests are not something everyone can do. You obviously also missed the point that i deal with VCU's on a regular basis and i have never come across a set of tests that you describe. It is recommended that you change a VCU on a freelander every 70,000 miles. no where in any manual for a VCU have i ever seen such torque tests recommended. So my friend im afraid it is you who is talking bollox and on this occasion, you are wrong.

There are 2 ways a VCu can fail. It siezes thus not allowing it to slip with the difference in speed between the front prop and the rear, resulting in IRd and or diff failure

It will not stiffen up when the shearing effect is caused within the unit thus not turning the rear wheels when required.

Please explain how you would go about doing a torque test on a VCU using tools you would find in your shed. Im very interested. I am also interested in the other issues you feel there are apart from the ones i have mentioned.

I am glad you recognise my superior knowledge and ability :D

I suggest that your "solution" does not take into account degredation of the fluid, or that it could have failed in an "open circuit" configuration. The fact that you habe never come across this type of test shows that you havent worjked extensively in this industry. The thread in the FAQ section is compiled from various sources (blatantly plaigurised), not my own work. The repair company (name conveniently forgotten) uses a long bar with a weight on the end, to check VCU effectiveness - this is a simple torque test!
How can I be wrong when this thread is about requesting peeps that can, or wish to do so, give feedback on the torque values they find if they decide to do such a test. If no-one conducts such a test, or posts the results, then there is no feedback.
All of this arose as an attempt to obtain a definitive test, rather than an arbitary "turn the rear wheel" or "You should be able to turn a good VCU by hand" type test.
I am a bit of a loss to understand how, if you "deal with VCU's on a regular basis " yet have no knowledge of the various ways in which a VCU can fail - particularly that it can fail with no through drive.
Any - as stated above, I am not forcing anyone to do anything. You obviously do not think that this is of any use - so thats fine by me.
 
The repair company (name conveniently forgotten) uses a long bar with a weight on the end, to check VCU effectiveness - this is a simple torque test!

And what does that prove. That it will turn or wont. What size weight is used and where does it say this. How fast does it fall? How can you work whether the VCu is faing or not??

I am a bit of a loss to understand how, if you "deal with VCU's on a regular basis "yet have no knowledge of the various ways in which a VCU can fail - particularly that it can fail with no through drive: I take it you mean no drive to the rear wheels when the viscosity of the fluid is at its thickest caused by the sheering motion of the plates?

Im not going to continue arguing with you on this. You have proved to me that you dont like to be wrong and that you know everything. Im also not going to start justifying my experience working with these units as the knowledge you have gained from this forum is obviously far more than i have in my 20 odd years working as a manufacturing technician on machinary that uses these very units. All i was simply stating is that there is a simple solution that Joe Bloggs can use to test his VCu without doing mythical torque tests.


:rolleyes:Every forum has one and you are it.

I agree entirely - hence the request for actual evidence of what torque is required, for those that might conduct the torque test. Maybe that company would like to respond? Actually I think they have on other threads.

Yes - I do, and a varying degree of drive if the fluid is not at its optimum.

Im not going to continue arguing with you on this. You have proved to me that you dont like to be wrong and that you know everything. Far from it - that is why I have requested figures - what is your problem with asking for information? It is only after the supply of this info that it can be decided whether the "torque test" is a valid one or not. You have made it plain that you think it not - others think it is - my mind is open on this.

Unfortunately I do not think it is precise enough, however it is a valid indicator.

You seem to have got that wrong. What im trying to say is that i think your a cock. You try to make yourself look clever and no doubt you have many sheep on here who follow you and your word. I myself see you as being full of ****. I bet your a right C**T to work for. So whatever m8. Your a waste of time.
 
Sigh!
I still havent figured out what yu are on about. The validity of the VCU "torque test" is irrelevant. This thread is just asking for feedback. If you think the test is crap then thats fine. If you think I am a cock, then sobeit. You wont be the first, you wont be the last. I do not try and make myself clever - I let others that know me better, be the judge of that. I am not concerned by your opinion. What relevance is it what I am like to work for? All I ask is ........
If you dont want to participate for whatever reason, then you dont have to, others might find it useful, just stop trashing a thread on which your opinions are irrelevant.
 
Keep it down you two :)

My original post just stated an easy way for joe bloggs to test there VCU. You decided to reply with negativity. I dont really care how much respect you have on this forum. In my life , you earn respect and im afraid you dont get any from me. Like i said, every forum has a guy like you. Think they know it all and will never be wrong. Yes i do think your a cock because you have given me reason too. My opinion may be irrelivent but opinions ard like arseholes. Everybody has got one. It just seems you come on here for a row. So ,whatever m8.
 
2 Q's
1) why have you posted a proposed test method on a thread asking for data?
2) assuming for the moment that your test is valid, how do you test for a VCU that is failing, but not failed and how does it differenciate between a good VCU and one that has failed with no drive thru it?

yu mite like to consider that not once have i considered name calling as an option. If you want to discuss this, lets do it on an adult level.
 
Forza Italia!



BTW - I'm interested in the VCU test, just bought a new 300Nm torque wrench from Halfrauds £79.99..................... bargain :D, its even got a rachet mech, something the old Britool one didnt :cool:

I have two props sitting, will probably do the free fall test with some dumb bell weights.

Starting at horizontal and time it until the prop hangs vertical.

Would have done this long time ago but errrrrr..................... been busy

:D maybe with some results, then we can formulate whether it is a reasonable test, and what the significant criteria are :D
 
Just tried the test in the video below. Did mine with an 8kg weight, on the end of a 1.2m pole. Wheel turns slowly, and you can see the vcu main body and rear shaft turn together, whilst the front shaft out of the vcu is stationary. My question is, how many times will the wheel turn until the vcu is locked? I've done it 10 times, one after the other, which is 2.5 revs of the wheel, and it's still not locked. Estimate about 20-25 seconds for the wheel to turn 90degrees. 2001 v6 with nearly 26k miles on the clock.

Thanks. I was wondering if it were not spinning fast enough to lock. I'll get a pole and have a go with more weight.

I wouldnt worry to much about it locking up - yu can test that on wet grass - I wouldnt think yu can turn it fast enough by hand. At least yu know it isnt seized :D.

Going back to your original post, you put..............
"In the FAQs section there is a VCU torque test, which you can (should) carry out on a regular basis, so you get warning of an impending seizing VCU. This is designed to reduce the chances of screwing up your transmission and having to replace your IRD."

My test that i put was a quick and simple solution to see if your VCU is seized without taking the unit off of your car, and doing said test. This is the main point of your test is it not??? To see if it is siezed??

I also put in a round about way in my posts that you can also see if the VCU is working as it should if the rear wheels get grip when the front lose traction. Is this not the same as seeing if the VCu is stuck in open circuit? Like driving on wet grass as you put in one of your posts. You obviously didnt understand this part as the negativity had already kicked in and your forum muscles started to pump.

Nearly every reply you have put on this thread has a Negative air to it.

I think your test as you call it is totally irrelivent to probably 99% of the people on this forum hence the reason i suggested an easier one. Now read back and tell me if there is any need for you to be negative apart from the fact that you are trying to stamp your authority as a major poster on this forum. Im not trying to impress anyone with my solutution, just making it easier.

As for the name calling part, Well im still convinced that you are a cock. You probably dont really get much anymore hence the reason you spend so much time on this forum. An average of 22 posts per day over 5 years. Thats sad. :hysterically_laughi
