I am upgrading to bearing and need to know if the stainless washer that sits between drum and old nylon bearing goes back to sit on top of bearing assembly. I am apart and on water. Seven two zero two two six five eight two five.
<blockquote id="quote"><font size="1" face="Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote"><i>Originally posted by djbano</i> <br />CDI says it doesn't go in but since the washer is only 1/8 it wont affect performance or cause damage. <hr height="1" noshade id="quote"></font id="quote"></blockquote id="quote"> I agree that the instructions say to remove the thrust washer. But I would caution against <u>assuming</u> that leaving it there would not affect performance because it's only 1/8" thick. Since CDI recommends 1/4" furling line, which may be decored in some spots, the vertical alignment between the cup opening and the drum's top and bottom is critical. If the drum is too high by 1/8" (relative to the outer cup), there could be a possibility of the furler line slipping off the drum and wrapping around the forestay inside the cup when unfurling the sail - a messy situation to clean up while under full sail. (And these sorts of things never happen in gentle conditions!) If the fairlead is placed to allow a perfect 90 degree angle with the drum, it's less likely that this would happen. But I've seen more boats with an incorrect angle than with a perfect right angle, so this is something to be concerned about. My recommendation would be to try it first without the thrust washer, and if you think the drum should be shimmed up by 1/8", redo it with the washer. (When I installed my ball bearings I redid it several times to get the right number of washers under the antirotation strap. It's worth the effort to get everything just right.)
CDI and rigging only said it won't affect performance and agree that the CDI manual and PDF is outdated that doesn't adequately show what goes in and what doesn't when upgrading to bearing. I'll take the washer out when the mast is down for the winter. Most people are probably brighter than me and don't leave the washer in.
