CCT Advice

[Fletch89]

I was confused, i realise it means top dead centre, my lack of grammer didn't help, sorry about that.

Spoke to AMCQ46 who's put me on the right track. I will def check that guide out.

Thanks

[AMCQ46]

Good man, and don't worry if you want to call again, and not so far away that I can't nip over.

Surprised you haven't heard me coming through Chadwick end when I do my run back from Warwick to Knowle. Was out on that road between xmas and new yr 2 times, but today I went off to Banbury / Daventry run.

Next time I am out playing I will send you a pm

Phew!
I thought it was me being thick.

Glad you're back on the right track.
The first "F" mark that you see when rotating the engine is the firing mark, after a few more degrees you'll see either RT (rear top dead centre) or FT (front top dead centre) It's those marks (RT or FT) that you need to use.
Not either of the the F marks, which you would need to use if you were setting the ignition timing manually, (which because it's electronically driven from the ignition pickup in the front of the clutch housing you can't, on these engines).

Finally after many weekends of not being at home, I finally managed to get into the garage to have a tinker. After setting the front cylinder position to FT and removing the front cover (a tad tricky) it seems the two timing positions are out of line. See link.

The chain has very little tension, is this simply lifting the chain and moving the cam round, or will use spanner something else. With it getting warmer would love to get this sorted this weekend.

Thanks for your help guys.

I cant see the pictures on my work computer as it is on a site our nanny fillter blocks. I will look when I get home and see if I can help.............but it might be late of tomorrow night!

[Fletch89]

Thanks, no major rush.

[tony.mon]

You might just have got away with this, if the cams only move one tooth the valves won't touch the piton, but don't start it or turn it over until you have replaced the front cct.
You will see that the front cct does not retract when you take out the end cap bolt and turn the screw inside with a flat blade electrical screwdriver.

Once the cct is removed you should be able to lift the chain over the teeth, but if you can't, undo a cam cap and lift the cam up at an angle so that you have enough slack.

fit manuals, or at the very least a new standard one with a stopper mod.

And do the rear one, too.

[AMCQ46]

As tony said, that cam has moved at least 1 tooth. With the CCT out there will be enough slack to move the cam under the chain, then refit the tensioner and recheck the timing marks.

I was changing to APE Manual CCTs from automatics, so there are installed. I obviously didn't gauge the tension on the front OEM tensioner when I installed the manuals. As I was unsure I took the front cylinder cover off and guides, the timing marks are a little out, but this is down to me being an ametuer.

So adjust the cams, the rears fine when i looked at the RT position, it is just the front. There should be about 5-10mm play in the chain between the two cams i am led to believe?

Thanks for your help guys!

[tony.mon]

5-7mm is enough play when cold.
Nearly there!

[Fletch89]

I'll get there slowly! Will have a bash this weekend!

Thanks

[tony.mon]

Will have a bash this weekend!

Too much detail, and stop getting so excited. They're only CCT's.

[Fletch89]

All sorted at the weekend! Bikes running fine. Thanks for your help!

[tony.mon]

Result, well done. It goes to show that perseverance pays.

I'm turning the engine over manually Anti clockwise, the camchain seems slack and rises just above the teeth of the cams. Does that make any sense? By the way firing the TDC?

Yes, it makes sense if you have removed the old cct, or it's failed completely.
Just get the new manuals in and reset the cams to the correct timing, following Sirch's thread in Workshop.


Unfortunately I cannot understand what you mean by "By the way firing the TDC".

Tony, you must be sick off us wally's by now !!
