JC900RR Posted January 10, 2012 Report Share Posted January 10, 2012 I was wondering if someone that knew what they were doing could give me an idea if my cam followers may be too worn and should be replaced while I have the engine apart. They look a bit worn but there's no pitting or anything. It's the top end of a 1987 Honda XR600R (RVFC). Is there a way of checking if they're in spec?

Evilchicken0 Posted January 10, 2012 Report Share Posted January 10, 2012 You can probably get them hard chromed but it might be more than a set of new ones (It's a single isn't it ???) Might be time to have a look for a replacement cam too, in which case a reground or performance cam could be the way to go. Link to comment Share on other sites More sharing options...
JC900RR Posted January 10, 2012 Author Report Share Posted January 10, 2012 Yeah money is a problem, otherwise I'd have had the cam re-profiled while it was all apart.. If these are going to last the next few races I'd like to keep them if I can. Do you think they're knackered? Was hoping there'd be a way to check them with calipers or something.. There's no dishing or anything on the followers, just look like they've lost a bit of the surface. Link to comment Share on other sites More sharing options...
RonniB Posted January 10, 2012 Report Share Posted January 10, 2012 Hard to tell, since the light is playing up a bit (or my pc is small and have bad resolution), but I don't think the wear is through the chrome, so they should be good to use. But give your oil ways in head a look, since the wear could come from insufficeint lubrication, could be old crap in the oil galleys!?! A stiff thin "piano" wire can poke it out, if done carefully. Another fairly cheap solution could be to have them dry film coated (camcoat springs to mind), that will keep the wear from developing, but I don't know if they are to worn to be considered.

Barry Posted January 10, 2012 Report Share Posted January 10, 2012 Yes, they are well worn. Can you feel a dip in them when you run your finger over? Link to comment Share on other sites More sharing options...

Ronni It's a bad pic there's no wearing through of the chrome, just slightly darker bits if that makes sense. Thanks for the advice, I'll check the oil ways. I'd ideally like to replace them with the valve springs when I get the cams re-profiled later in the year, so just worried about if they'll last that long! Would be pretty shit for the top end to lunch itself just after spending loads of money on a new big bore kit.. Yes, they are well worn. Can you feel a dip in them when you run your finger over? Definitely no dip at all. Link to comment Share on other sites More sharing options...
Barry Posted January 10, 2012 Report Share Posted January 10, 2012 Could just be the light then, but to me, from what I can see in that pic, I wouldn't use them! Link to comment Share on other sites More sharing options...
JC900RR Posted January 10, 2012 Author Report Share Posted January 10, 2012 Well it sounds a bit touch and go.. Better be on the safe side, I'll look into finding replacements before I get it all back together. Thanks. Link to comment Share on other sites More sharing options...
cagimaha Posted January 10, 2012 Report Share Posted January 10, 2012 I can confirm that you can't feel the marks when you run a finger over them. Also though it would be an excellent idea to check the oilways it would also be a good idea to learn how to check the oil level properly Link to comment Share on other sites More sharing options...
