Tmacmi 1 #1 Posted August 28, 2019 I this cam no longer has much spring left in it. (I jammed it up prior to the photo) Has anybody repaired one of these cams (see attached) Its aluminum and mounted on the boom. I tried to take the clip off this past weekend and it was a bitch so I started fussing with other stuff.Reef Cam.pdf Share this post Link to post Share on other sites
See Level 703 #2 Posted August 28, 2019 It's not run right either, the line should go over the top of the sheave. After that try some lube on the cam. Share this post Link to post Share on other sites

I'll admit I tried a half dozen times to figure out the path of travel. I just got the boat 3 weeks ago an that wasn't rigged. I tried going over the sheave but I couldn't figure out how the line can go over the sheave and still run through the cam. Share this post Link to post Share on other sites
RImike 149 #4 Posted August 28, 2019 Looks like the cam and the sheave are reversed. 1 Share this post Link to post Share on other sites
SloopJonB 8,321 #5 Posted August 28, 2019 I think Mike has it - pop those snap rings off - I'll bet the spring in the cam is dead - then reverse them on the pivots. Be prepared for them to have dozens of loose, tiny little balls that will spill all over the deck when you slide them off - have someone hold a plastic tub underneath when you slide them out. Don't ask me how I know this. Share this post Link to post Share on other sites

That would seem to make sense, but See Level jogged my memory of an almost indecipherable rigging plan in a old copy an "owners manual". From what I can see plan calls for the line to run as shown in red in the attached pdf and the cam to jam it before the sheave as shown in blue. If that is the case the cam spring is blown. So question 1) can this be done while the boom is on the mast in the vertical position? I have no idea how you would repack ball bearings in that orientation. 2) where do you get replacement springs?

Looks like the lever handles been broken off. No ball bearings in those old Kenyon cams. Share this post Link to post Share on other sites
longy 496 #8 Posted August 28, 2019 The above pic is the correct layout. No balls anywhere in those parts. Share this post Link to post Share on other sites

No ball bearings in those old Kenyon cams. That makes much more sense. The cam does it's work against the boom itself. I don't think there's a spring there, either. Just the missing handle.

Tmacmi 1 #10 Posted August 29, 2019 Thanks to all who helped. Rig Rite may have a direct and improved replacement. I'll let you know. Share this post Link to post Share on other sites
welder 2 #11 Posted August 29, 2019 If rig rite doesn't have one I might have one on my boat I would have to look Share this post Link to post Share on other sites
