paddle Posted February 20, 2021 Posted February 20, 2021 Hi is there an overhaul procedure for the cam chain tensioner on a B12 or is it a bin it and buy new Thanks Quote
TonyGee Posted February 20, 2021 Posted February 20, 2021 whats wrong with it ? are the teeth worn ? the spring can get a bit week over time but a washer or two can help, but dont over do it. is the chain rattling ? it could be on the verge of clicking to the next tooth. Quote
bluedog59 Posted February 20, 2021 Posted February 20, 2021 Check the spring length against spec. They have a service limit and quite cheap to replace. Give all the internals a clean while you're in there. Quote
wraith Posted February 20, 2021 Posted February 20, 2021 New OEM springs are not a lot of money. New spring and washer (under bit nut) and you're sorted. Quote
