We have a Hurth HBW-150 R2 transmission that is slipping, and we may have to alter our cruising plans as a result.. I really don't want to continue without a workable transmission as I've seen too many situations where sail alone was inadvisable, especially in some of the Bahama cuts.. We changed the fluid, checked the linkage, and have been babying it since first noticed.. It doesn't have an oil cooler, and I'm aware that might help, but what we have is what we have.. Anyone with suggestions? Diana I guess the first question is how do you know that it is slipping? But if you are positive that the transmission is slipping then the only solution is to rebuild it. A Hurth is a very simple transmission - two clutch packs and a second shaft and gear set to reverse the output rotation. If it is slipping then the clutch plates are worn and nothing you can do is going to make any real difference. An oil cooler won't make any difference at this stage but if you do rebuild then adding a cooler might make the rebuilt box last longer next time. Foley Marine is a good source of parts and information regarding Hurth boxes although there are plenty more on the net. http://www.foleyengines.com/Home.aspx Bruce-in-Bangkok (correct email address for reply) |
