Need to give Engl an order here I think

Danke Terje,
Bestellung angekommen, sende sie dir am Freitag zu.

both in aerospace and oilfield it is wirelocking that is the no.1 way to lock anything. second is split pins.
We do see Norlock in some places in the oilfield now so I'm familiar with that too.
However wire is still preffered as it will generally hold the item in place if it fails (i.e snaps off, shears ect) and it wont drop and hit someone.

As this forum is a lot about bang for bucks, you really can't beat a piece if twisted steel wire.

I am a little skeptical to the small plates, are they bent and of a steel with some spring in it?
to me it looks like it works pretty much like a spring washer at best.

I am assuming those plates shown are not fully fitted as I would expect to see one edge tapped up to positively lock one face of the hex.

As it is, it locks nothing.

Also, copper and alloy washers crush and over time can lose their tension, hence (I believe) loosen the bolt.

This will never happen with stainless steel lock wire.

It's would be best to replace the banjo-bolts completely. The pre-applied threadlocker may work, but you'll never be sure. It may be OK for a year or two and then... However, I guess for the threadlocker to have the best chance of working you'd need to degrease the female threads.

I would buy a set of new bolts and then drill the heads so that they can be wire-locked

This is by far, the best option.

Gerry is of course correct - the above picture is but one out of a set of many included in the link Smileitsme posted way above and to which I referred.

Here is a picture of one of those properly installed.

Cheers

Thanks Reinhard.

I was not being deliberately awkward but didn't want anyone to buy a set and then think they were installed as shown previously.

Your second pic is far more informative to anyone choosing that option and works correctly as shown.

No criticism was intended.

Since I'm still on holiday I don't have all my datas with me,
but the copper washers that I sent to André years ago
( couldn't find the pic on my HD here in Italy, lot's of pics got lost when
I changed the server) work with the same pinciple - they look like these.

Yes that does look better, now I believe in them too

This issue has been very interesting and informative if not slightly worrying for M70 owners. We are lucky on this forum to be kept informed of such matters but what of the many other owners that could not possibly know about this?

My question is, what are the symptoms or problems that arise if the banjo bolts have come loose? Obviously it is a concern if the bolts are found to be loose when checked, but does anyone actually know of any instance where this has led to major problems.

My final question or plea is, could someone do a "how to" on how to get to the stage where the bolts can be checked; I had a look the other day and

I can be quite handy but didn't have a clue where to start.

Thanks

Basically no symptoms until.... it´s too late.
Cam lobes deprived of oil will start to wear. Once this has started it is moving towards a very expensive repair usually requiring a new camshaft.
This happening (once wearing down: increasing valvetrain noise, loss of power in upper rev range) basically led to the detection of the root cause: loose banjo bolts.

A few cases of worn cam lobes are known here. Many others escaped that fate

Understood, so what is the procedure for exposing these critters as it looks to be quite an extensive dismantling job to get to them?

Thank you
Graham

On this page you will find the general procedure to get down there.

Not having done this myself I´d probably just pester Terje (Huldra66) about additional information.

Now thats a workplace where you want to spend your time.
Have you ever been to Poland?

I thought the same thing!

Zitat von Fatandre;105773

Have you ever been to Poland?

No, but I am beginning to think just about anywhere has to be better than this overcrowded and depressing island; I think maybe somewhere with a bit more sun though:)

Thank you Reinhard and Terje for the directives. It is still quite a job that I will clearly have to get around to at some stage; it is not a winter's evening job that's for sure.

I can't believe everyone else on here already new how to do it, or did they?

Cheers
Graham

Well. It was asking Terje, but you can come also. I am frankly quite scared to tackle this by my self.

Yes last year better Roads and warmer Thea Norway

That cannt be true.
You should then be riding on 13" wheels with a lot of rubber
