(New!) Topic : Cam chain timing  Author  Post     DrMooman  Set Reg. Date  :  09/08/2016 Posts  :  73 Location  :  Wales, Wales, United Kingdom Posted : 07 Dec 2017 - 06:30   Post title : Cam chain timing   Another question for the experienced people- im now in the process of setting the cam timing. The question is how many pins should there be between the two timing marks? In the picture in the triumph manual there are 19 pins and both timing marks are just inside of the marks on the cam ladder. When I took it apart both marks were inline with each other (not as they are in the triumph manual) and when setting them this way there are 20pins between the marks, which is what some advise on triumphrat forum. What do you guys reckon- 19 or 20 pins? I'm leaning to setting it as per the triumph engineers intended, 19 pins. Anyone got a counter argument?  Author  Post     Leethal  Zeus Reg.

It's easily checked once you have finished by removing the timing pin and rotate the crank another five hundred times and then insert the pin again and see where your marks are. I don't recall the SM mentioning counting pins as part of the procedure.   Experience is something you get just after you needed it 1600,Foran Razorbacks, Meerkat bypass, Dyno tune, real headlight,plenty of chrome,switchblade pegs, Nitron R3 shocks & Ikon progressive fork springs etc. Scorpion Western Low handlebars.

The difference would be the timing of when the cam lobes make contact and that might make a difference I guess. If you set the cams in the wrong position but it is set then when you rotate it it will eventually return to that wrong position. So I guess it is more of where is the exact placement of the cams relative to the timing marks on the cam ladder as you can set them slightly left or right of the mark but not bang on. Or am I just being too exacting  Author  Post     Leethal  Zeus Reg.

The most important thing ( IMO) is to make sure the cams line up as best as you can with the ladder marks AND that all the chain slack is to the tensioner side. If the timing pin is in and the cam marks are lined up and the back of the chain is tight then everything can only go in one place. It won't matter if the cam marks are slightly either way of the marks on the ladder. I don't think I have ever seen them line up exactly. As I said if you get it wrong it will show up after you have done the next set of rotations, which you should always do anyway.   Experience is something you get just after you needed it 1600,Foran Razorbacks, Meerkat bypass, Dyno tune, real headlight,plenty of chrome,switchblade pegs, Nitron R3 shocks & Ikon progressive fork springs etc. Scorpion Western Low handlebars.

If you set the two cam's 20 or 19 pins apart they both are not directly in line with the marks on the cam lobe. The key problem is i'm not sure how the cams should line up. I was originally going to put them as per the picture in the triumph manual- but then i though- my bike was working fine before i took it apart so i want to put it back just as i found it but with updated shims. Also others have posted on this forum, Triumph Rat, PB90's pictures also confirm, and the pictures i took before i disassembled- all indicate 20 pins and the marks are not in the same position as those depicted in the triumph manual. I bought mine second hand so i don't know if some other mechanic did mine and didn't set the position as per the manual or if that is in fact how it comes and it is the picture is wrong. For now I'm sticking with putting things back how i found them to minimise the risk of there being a problem as there wasn't one before. However, it leaves me wondering- what difference does 1 sprocket out make in the running of the bike?  Author  Post     Leethal  Zeus Reg.

Post a pic of yours before you disturbed it. Whoever started counting pins has thrown a spanner in the works. Remember it's a drawing, and I doubt very much if it's to scale, I mean are we going to count the number of teeth on the sprockets? Just follow the procedure as it's explained in the SM, you can't go wrong, forget about pins.   Experience is something you get just after you needed it 1600,Foran Razorbacks, Meerkat bypass, Dyno tune, real headlight,plenty of chrome,switchblade pegs, Nitron R3 shocks & Ikon progressive fork springs etc. Scorpion Western Low handlebars.

Anyway by now you will have done the next set of rotations and will have seen where they line up.   Experience is something you get just after you needed it 1600,Foran Razorbacks, Meerkat bypass, Dyno tune, real headlight,plenty of chrome,switchblade pegs, Nitron R3 shocks & Ikon progressive fork springs etc. Scorpion Western Low handlebars.
