A number of members have mentioned problems with early Schaefer Jib Furlers seizing up. ¬ Note that you should never use petroleum based lubricants on Marlon bearings. From¬ Stan of¬ Frankie Anne¬ C380 #247¬ East Greenwich, RI: I just had to fix the same issue. ¬ The bearing design in the lower unit was changed at some point. ¬ The newer models have, I believe, bearings in tracks rather than loose. ¬ The unit still needs to be rinsed periodically but holds up better. ¬ The lower swivel with the new design is available from Schaffer and costs about ¬ $200. I opted to have a rigger do the work due to some complications but it’s a reasonable DIY job.
