As a proactive move (65,000 kms), I pulled the cam cover on my 02 WG and inspected the cam chain tensioners. The primary tensioner was wore significantly and the secondary was barely worn . I replaced both anyway. The INA bearings are in excellent condition and I decided not to replace them because I don't have the proper tools as yet. I may do so this winter. The Cam service kit that I purchased includes all the bearings including the same INA inner bearings. My question is this: what cams are in my engine and why is the tensioner wear the reverse of what would be expected. The cams do not have the typical timing marks as described in the Harley manual, but have and "A" and a "1" on the rear cam and only what appears to be a hand engraved line on both cams and these marks are the only similar marks that appear to line up as timing marks. Is it possible the cams are after market Andrews cams installed by a previous owner? I have also been told by a Harley mechanic that the primary tensioner typically shows less wear than the secondary. My thoughts are that the cams were switched out and at the time the primary tensioner was is such good shape that it was not replaced, but the secondary was, hence giving me atypical wear results. Does any of this sound plausible???
