pesky Camshaft problems

[Colin Alford]

Andrew,

I am not an expert and have not rebuilt an engine myself. After reading your post I consulted the manual UC-F1 and it states "The bolt holes in the camshaft flange are unevenly spaced to prevent improper assembly of the gear to the shaft" Once you get the right orientation of gear to shaft then you would just have the two timing marks to worry about. Would that keyway allow you to turn the camshaft? If so, you may not have to disassemble to valve train to sort out the timing issue.

Again, I am not an expert.

thanks Guys, I think the panic may be over. But, Colin you may well be right, as it would be inconceivable not to be able to time the gear to the cam correctly. Without such a set up the timing marks on the cam gear would be worthless. To the naked eye, its not possible to see a difference to the holes BUT the tab washer will only fit one way. Anyway, I took off the cam gear and had a really good look at it. I could see that there was an imprint in the back where the cut out in the cam flange is. I therefore put it back like that, and then found the cam gear marks were one fairly obvious one, and one more like a scratch. Retimed it, and just tried a compression test and hey presto we are in zone now. I imagine that when I get the front cover back on and the distributor back on tomorrow we may have lift off. Thank you for your input and help. Sometimes you just need to discuss these things to make sure you are not missing something obvious. But I am sure you are correct, Colin, the holes are spaced differently. Fingers crossed.
