ThomS 14Oct07 === in Technical Manual Westerbeke 50 Marine Diesel Engine Pub #23156, Ed. one ________ date 020 Svc.Bull. #20: Oil Pressure Sensing __/__/__ p:V.2 don't remember what this is actually about TODO: look it up 069 Svc.Bull. #69: Exhaust System _____ failures? __/__/__ p:V.3 TODO: what's this about 072 Svc.Bull. #72: Gauges -vs- Senders non-Interchangeability __/__/__ p:V.4 4 different manufacturer sources for instruments gauges require matching senders; outlines of the different gauges are given 076 Svc.Bull #76: Bleeding Hydraulically Governed Fuel Inj Pump (if fitted) 08/27/75 p:V.5 special procedure for anti-stall device to hold the locknut in position when opening bleed screw for this unit, because the locknut setting determines the adjustment of the anti-stall feature; losing that adjustment may not let engine start, even after bleeding. 081 Svc Bull #81: Muffler (don't remember subject) __/__/__ p:V.7 TODO: look up why we remember this? 082 Svc Bull #82: Battery Recommendations __/__/__ p.V.9 084 Svc.Bull #84: Heat Exchanger Rubber End Cap Positioning 09/04/75 p:V.__ reassembling heat exchanger requires a particular alignment of end cap on the exchanger body 087 Svc.Bull #87: Alternator Output Splitter 09/18/75 p:V.__ optional splitter discussed; might require rewiring where charging voltage is taken from the alternator (from regulator output rather than "generator" screw) Note: We don't think Nevermore has this optional device (Sep07) but it IS included in engine 12-v electrical diagrams. 2-way splitter P/N 20654, alternator max 120-amp, will give charging voltage approx 0.8-V less than usual. 092 Svc.Bull #92: Troubleshooting W.T. and O.P. Gauges __/__/__ p:V.__ gives some step-by-step tests, and a couple admonitions about what NOT to do 094 Svc.Bull #94: Fues Pressure Switch Installation 09/09/76 p.V.15 Thom remembers this as discussing how to ADD switches and locate them if more switching is required; also remembers this is where we got insight into the one switch we do have, and the implementation of the "keyless" ignition Nevermore has === http://www.westerbeke.com/technical/service_bulletins.cfm Service Bulletins (Numeric) SB# Service Bulletin Date 104 Service Bulletin #104: S.W. Pump Pulley Set Screw - Westerbeke 30 & 50 01/22/80 make sure waterpump pully set screw #11357 must be tight! 107 Service Bulletin #107: Thermostats - All Models 05/01/80 >=May 1980, bypass hole allows some water circulate during warmup; this flow is mandatory, so use genuine Westerbeke thermostats 114 Service Bulletin #114: Water Heater Installation - All Marine Engines 05/06/82 use of Westerbeke FLOWCONTROLLER in hot-water circuit to allow suffient flow for users, but also good circulation for engine. Also lots of considerations of not having trapped air (use continuous slope from WH to engine, or install bleed petcock; avoid loops in tubing trapping air. Also: FLOWCONTROL kits available to retrofit late 1980-82 W. engines; different for manifold on left or right side. 121 Service Bulletin #121: Shift Cover Sealing - All Marine Propulsion Engines 03/18/83 Not applicable to Nevermore, probably (except IS for HBW xmissions, and the moral for us is that we shouldn't mess with this cover! Shift cover put on now (>= 03/18/83) with orange loctite, replacing use of gasket #22207; warranty broken if this cover is removed..." 125 Service Bulletin #125: Oil Pressure Switches - All Models 08/14/83 TODO: check whether we have hex shaped case with indented corners, need special wrench socket 132 Service Bulletin #132: Manufacturing Date Code - All Models 11/08/83 TODO: compute date based on Nevermore's engine number 136 Service Bulletin #136: Shift Lever - All HBW Transmissions 02/09/84 Thom thinks this is applicable to Nevermore this is for HBW (Short Profile Sailing Gears) 148 Service Bulletin #148: Tachometer - All Propulsion Engines 01/23/85 probably pertains to Nevermore TODO: check part-number of H'more's tach to 11917 here 153 Service Bulletin #153: Fuel Pick-Up Screens - All Models 04/13/85 don't know if we have a screen 162 Service Bulletin #162: Exhaust Elbows - All Models 02/28/86 don't know if we HAVE "locally fabricated exhaust elbow" 239 Service Bulletin #239: Transmission Lubricant Change - All PRM80 and PRM 120 Transmissions 10/27/03 NOT Nevermore we think change from hvy oil -> ATF (Dexron III) 242 Service Bulletin #242: Manufacture Date Code - All Models 08/20/04
