KV6: using timing service tools

Yes Mike, that's the theory but not the practice (see post no. 2).

Usually necessary to slacken the front chainwheel to rotate the inlet cam slightly to achieve this.

In so doing you would be altering the timing from, in my case, the factory setting. That process then makes your understanding (and mine) incorrect. I do not feel inclined to do that since my engine has always run perfectly.

But, if you are doing the belt change without the tools ...

I am using the service tools (as stated in thread title). Let's not muddy the waters eh?

I say Simon, those belts of yours appear to be in good shape.

Thanks Tony but that subject has received very heavy coverage in a thread which is temporarily closed. Now, I am interested in comments on the subject of this thread. If you have done this job yourself Tony, did you find the same problem which I have described?

But now the locking pin won't engage with the flywheel!

Simon , I attach an extract from the Sealey tool instructions :
To 'lock' the camshaft insert the pegs of the Camshaft Locking Adaptor into the front sprocket hub and then insert the Locking Tool spindle
into the end of the exhaust camshaft (location pin into slot in camshaft) - fig. 6.
Is your problem because you are inserting the tool into the exhaust cam first ?
I find that you put it in the sprocket first than turn the whole tool a tiny bit to locate the other end into the exhaust cam ; easy Your inlet is now perfectly timed so long as the crank is locked .

Just for interest I attach the Sealey instructions . I find them very good !

Errh, what about just replacing the belts as I have suggested for the last 10 years, keeping the marks in place, then you timing will be exactly as it was.




Or are people still struggling to understand what is going on here.?

[kaiser]

I have just read those instructions. Note the illustrations. Where are all the marks?
I must sit down while I laugh.

Thanks for the suggestion Chris. I tried both, into the exhaust cam first and into the inlet sprocket first. I found it easier to insert into the exhaust cam first, particularly on the LH bank, because the low pressure air conditioning hose bears against the tool making rotation difficult when restrained by the other end being held in the sprocket. On the RH bank the air con. pipes again make the process difficult but raising the engine a bit more helped.

But really, it shouldn’t make any difference which is inserted first should it? The tool either fits or it doesn’t.

Use of the service tools renders marks obsolete it seems to me. That’s maybe why they’re not mentioned.

Well, that answers that question!
