bob654 Posted May 7, 2023 Share Posted May 7, 2023 So I should have replaced this earlier, decided to do it now. A few questions Do I need to remove cams? Can I just remove tensioner and guide? Do chains come the correct length? Do I need to shorten them to fit? Have I missed anything? Thank you. Quote Link to comment
fatblokeonbandit Posted May 7, 2023 Share Posted May 7, 2023 You have obviously missed the bit where you buy a manual and read it, if you don’t know whether you need to remove the cams, then you really need to read it……… 1st thing to consider, endless or split link! 1 Quote Link to comment
TonyGee Posted May 7, 2023 Share Posted May 7, 2023 the first cam chain I replaced waaaaay back in the 80's on an XS250 came with only a split link !!!!!! Quote Link to comment
bob654 Posted May 8, 2023 Author Share Posted May 8, 2023 I'm not putting an endless chain on. I have a manual , I will have a look later. Thought there may be a way of doing this without unclamping the cams, just taking off the bridge? Quote Link to comment
Gixer1460 Posted May 8, 2023 Share Posted May 8, 2023 Think about what you are proposing! If you leave the cams in they will not be rotating. At any point one or two valves will be opening / off their seats / closing. To feed the chain in you MUST rotate the crankshaft. Doing so, risks driving the pistons into open valves and bending them! Still want to leave the cams insitu? 1 Quote Link to comment

Thought there may be a way of doing this without unclamping the cams, just taking off the bridge? Good advice from say what now!?. I would add, get a mate, or your lass to help feed the new chain in/remove old one while you’re turning the crank. Lot easier than doing it on your own. Also bear in mind, if you don’t keep both ends of the chain tight during the process, you could end up with a loop of chain under the crank sprocket. Then you’ll be calling your supplier all sorts for sending you the wrong chain! Just take your time. Quote Link to comment
