Hello all, (from canada)

I am in the process of putting back together a TEA20 tractor and am looking for some info on the correct way to set the valve timing on the 80mm standard motors engine.

Can anyone help?

Thanks,

David
 
Are you reinstalling the original cam shaft and crank shaft sprockets? If so they should have small punch marks which must be aligned.

If you are installing new, unmarked sprockets, they can go one either way and you will need the manual or extract copy.

If you have removed the chain-wheel from the Camshaft then it is more difficult, if you have not removed the Chain-wheel it is just a matter of aligning the scribe marks on the chain-wheels on the Camshaft and the Crankshaft. If you have fitted a new chain-wheel on the Camshaft then you will need the info to reset the timing. If you email me and let me know just what you have done and if you have had the Chain-wheels off or not and if they have scribe lines on both of them, I will send you the information that you need to set the timing. You should have a new chain at this time, if the old one is at all slack you can't set the timing with any accuracy...John

Thanks, I was able to find the marks on all the original parts and used them to set up the new chain and sprockets.
 
One more question. How do I install the distributor correctly? :roll:
I have a PDF manual for the tractor, but the info relating to the standard motors engines is limited.

Thanks
