wheels for selden single line reefing cars

[BWCY420RS]

Hi each

Just got the single line reefing cars out of the boom. On each, 2 of the wheels had gone/disintegrated and the other 2 had worn so flat that rotation was not likely - adding more friction into the system. Any ideas for replacement items (other than Selden). A Bunnings option would be great

Cheers

With respect Ross, the proper term for what you call a "wheel" is "sheave".
I doubt you'll find marine quality sheaves at Bunnings. Try West Marine or other chandlers.

Sorry mate, they are actually called wheels as they carry the car inside the boom. Check the Selden catalogue (for the boom section 171, Selden part number is 504-346).

my bad, good luck finding them.

any metal shop can machine them for you from polyacetal

Hey mate

Hope you managed to find a cheap part.

I have that boom and am noticing a lot of friction, do I need to drill out rivets to get to the issue or can I just pull apart the end with a Torx screwdriver?

Thanks bud,

Will

watch out, when you pull the end-casting out! Axles & sheaves drop out (& are not floating!)

Sorry about the delay in replying.. frantically getting boat reading for departure and considering the niggles found... not succeeding. But we have left.

@wgregor. Yes, Torx screws and some gentle taps with a rubber mallet. Hopefully, the last person to remove the screws cleaned them up and reapplied antiseize etc. Then pull back on the reefing lines. Top tip... put a screwdrive or bolt through the torx holes to stop the cars flying out (then watching the little wheels go plop over the side). If you know the boom section, you can find the correct parts here https://support.seldenmast.com/files.../595-081-E.pdf, then its then joy of selling a kidney to pay for the parts.

Thanks Ross,

From your experience which are the main components which can cause resistance? I get the sense that my lines may be a bit proud for the pulleys. Might have to swap out for some thinner dyneema.

Thanks again, super helpful

Hi wgregor. just noticed you are in Plimuff. Hope things are good - I am a janner relocated to Sydney.

The system has far toom much friction. I reduced line size from 12 down to 10 or 9, with dyneema/spectra. Have a look at where the fixed luff lines exit the boom. on my boat they were rubbing the cheeks of the exit sheaves. The leech lines go into a complex block system on the cars. When I pulled the cars out of my boom, I found the blocks had been twisted so that there was a crossover between the blocks at the clew end and the blocks on the car.

Note that the luff-lines are spliced onto 6-8mm mins on the cars - something to factor into a refurb

Good luck

Cheers

Ross
