Ignition timing with inspection port
« on: March 01, 2021, 09:09:24 PM »
Hi Mokers,

I have fitted one of those Romac harmonic balancers which is a nice piece of Australian art work/engineering which has all the correct timing marks on but I don't have a timing pointer on my timing chain cover. 

Can I do my timing with a light using the inspection hole on the fly wheel side? 

If not, can I set up my own timing point on the timing cover so that I can use the markers on the Romac harmonic balancer?

Thanks Brad

I would say that using the flywheel to set and mark the balancer timing cover would be my approach.

Thanks, I think?

How do I set a TDC mark on the timing cover using the flywheel inspection plate?

there is a TDC mark on the flywheel so wind motor over by hand till TDC is on the pointer in the inspection opening then
mark that on the crank pulley, then wind over to say 10 deg (both BTDC and ATDC and mark that on crank pulley.

Photo of nice piece of Australian art work/engineering would be appreciated.

I have all the marks on the balancer,  I just need a TDC mark on the timing cover so I can align with the balancer.
Thanks Brad

Hi Brad,

Is that a viscus fluid dampner Like the K.A.D. one?

You could make up a pointer for the balancer and use a timing cover bolt to hold it in place.

Cheers
Dave

Nah Dave it cost half the price of one of those.  It's solid steel and weighs a ton though. 
It comes with all the markers and was a bitch to fit because it's tight tolerances.   
Now all I need is a pointer on the timing cover.

Is their a specific spot I need to put a timing pointer on the timing cover?

The position of the later model additional timing scale on the timing cover is shown in the Haynes manual in the ignition section.
There is a diagram and a photo.
