- Shims have now been changed and this video recaps on how I set the valve timing, refit the cam chain tensioner, alternator and alternator rotor.
Just getting ready to refit alternator cover and cam cover.
Watched all 4 videos I have a storm, Thank you for going to the effort to show how you went about doing the valve check.
Thanks for you comment. I have one more video to conclude the series which I hope to get out sometime this week.
I appreciate the video. Pretty sure I am going to pay a professional to do mine. Nice work! :)
Thanks for the comment Kenneth. There were certainly times when I thought I should have took it to the dealers but it all came good in the end.
Thanks for watching.
Hi PB60, my cam chain sits on the cam sprockets with the mark on the sprockets aligned with the middle of the chain link rather than between 2 links as your picture shows. Is this a problem or has the chain slipped on the drive sprocket 1 tooth and the timing is still ok. There are 20 pins between the marks on the cam sprockets which is correct. The tension is tight on the back side as specified. Your comment is requested.
Hi Kathy, I am no expert in this matter and posted this series of videos as a guide to others who might like to venture into having a go themselves.I would say that as long as you have the crankshaft locked in the correct position with the pin and the marks on the camshaft in the right position the detail on the chain shouldn't matter. It certainly wasn't something I considered when undertaking the work. Make sure the chain is sound on the bottom sprocket. If it bothers you that much you could possibly let the chain go slack and move it round on the bottom sprocket. Hope that helps, PB.
Hi Kenneth. Firstly thanks for the speedy reply. I carried on and installed the chain tensioner. I removed the locking pin and rotated the crank until I could get the pin back in and lo and behold the timing marks were as shown on your photos and lined up with the ladder marks. Interestingly the timing marks moved from the middle a chain link to between 2 links. The critical piece of info for me was knowing there have to be 20 chain pins between the sprocket timing marks. It would be easy to get that wrong. The hard part was holding the intake cam against the valve spring pressure while trying to align the 2 sprockets while installing the chain tensioner. This I did with a small adjustable wrench on the hex cast into the intake cam. Thankfully the exhaust cam is freewheeling when aligning the timing marks. It took many tries before I got it. BTW the Triumph shop manual is useless for this job. No one should attempt this job without the locking pin that's for sure. Your videos were a godsend. Thanks.

Hi PB60, my apologies for the name confusion.
Hi Martin, I must admit there were times when I struggled with the Triumph shop manual but I guess it's really there for their trained technicians. Pleased it's all worked out ok for you and thanks for the comments. Regards PB
Hi PB60 just one last note to thank you for the details on the locking pin and the alternator rotor removal bolt. Using your dimensions I was able to have a machine shop friend make them for me. If anyone reading this is interested in details of either I would be happy to send them a drawing.
