Re: New gearboxes - painted or bare alloy?
I've ordered several sets of these gearboxes from Bonfiglioli and they all were delivered with no finish. I finished them the same or similar way I would have finished an aluminum part at Boeing. That means a thorough cleaning to remove grease from surfaces, a coat of Alodine, two coats of zinc chromate primer, and two coats of enamel. Having said that the first two units external surfaces showed heavy deterioration after two years of sailing around the world in the South Pacific and Indian Oceans meaning they saw a lot of salt water spray. The other two units were just installed so have no sea time yet. On these last two units I skipped the Alodine. If the supplier is willing to finish them for you, I would recommend that you accept that as they can probably do a better job. I would also recommend that you install a cover over the units to protect them from salt water spray as suggested by another thread regarding these gearboxes. Even wrapping them in a plastic bag or shrunk wrap would be preferable to no protection in my opinion. But I'm no expert so check with the other thread on this topic.

Volvo 24v alternator exciter
24 V alternator recently requires higher RPM before producing voltage. Any suggestions about where to start troubleshooting? Exciter circuitry? Thanks!

Re: generator pcb board
Jeff, Thanks for sharing. I checked and that PCB, part number 327-1533, is also used in MDKAV, MDKAW, & MDKAZ...maybe others. Bill

Re: converting 24v alternator to ribbed micro v (serpentine)
Hi Oliver,
toggle quoted messageShow quoted text
If you are talking about the small pulley on the alternator itself, it is very tight, so you may have to take the alternator off to a garage that changes car tyres and ask them to use the compressed air socket set. However I did not need to do that. The problem is how to hold the shaft of the alternator whilst undoing the nut. If you use a screw driver in the fan blades then you will damage it. If you look closely at the end of the shaft where the pulley nut is threaded you will see a hexagonal hole that will accept an allan key. You still can not use a normal socket as that would block the access to the hexagonal hole. You could use a socket with two flat sides to put a big wrench on, then undo the nut whilst holding the shaft with the allan key. When the nut is removed you may need a puller as the pulley should be a snug fit on the shaft. If you are talking about the big pulley bolted to the engine pulley. There are 4 bolts that can be removed quite easily. Then use a long bar to gently lever off the pulley. I hope that helps a photo would make it easier to explain. Nick Amelia AML 54-019 Greece

Re: generator pcb board
Thomas Kleman
I know you've probably done this but I wanted to share my experience. My MDKAV gave me a "call tech/bad cpu" message once. But when I kept testing it became apparent that only the AC units caused this. I changed the capacitor in the AC pump (the only commonality) and all was OK. My MDKAV sometimes gives false error codes so a bit of deductive testing is required to prove the cpu is bad. I have a spare so of course I've never needed it (yet).

Re: Batteries starting to get weak - MMM - What to do -
Oliver Henrichsen, SV Vela Nautica
Hello, Good BMS systems measure 0.001 Volt with +/- 2 exact. Balancing is over evaluated in the thread. A good batterie setup stays balanced for years after initial balancing if needed at all. You may check on it from time to time but a good system will hand a banalce Alarm anyway. Active balancing has no real advantage agains passive balancing. It only reuses a tiny bit of energy instead of dissipating it. Oliver from Vela Nautica A54#39 Martinique

generator pcb board
JEFFREY KRAUS
Good Day Amelians
Recently, I was running system checks aboard s/v Spirit before a planned run from from Puerto Rico back up to Long Island NY. My gen set shut down upon starting and indicated an error code of 3 flashes. That code asked for a second code, which when generated translated to requesting that a a certified onan technician be called. My generator is an MDKAW circa 2005. When I ran it by my onan dealer back on LI, he indicated that it was the pcb board (the brain), or the whindings. Whindings checked out ok. I contacted Onan, they had none in stock. They ran an engine down worldwide search, and still came up with none. Making matters worse, they said the company that makes the board for them is out of business (due to covid), and they don't expect to have a new supplier of this part in place for 6 to 9 months. Fortunately, I found a parts supplier on ebay that has the part in stock. It's a few hundred dollars more then thru onan, but they have it, and it has been shipped. The fellow I spoke to told me they had 12 in stock (it's now 11 lol). My board is a pcb board part # 327-1533 The company is Arkansas Valley Diesel Service. Phone # 719 9316003 If anyone else runs into this issue, I hope this will save them some aggravation. Best Wishes to all Amelians. Jeff Spirit Amel 54 #14

Re: New gearboxes - painted or bare alloy?
Ian Park
Mike,
You may have to grind the fins off the mainsail furling gearbox to fit in the mast profile. So you’d need to paint over anyway. I changed mine three years ago. I painted with an aluminium primer and top coated with a one pot paint that matched the mast/boom. It’s worked fine, and if it gets scruffy I can paint it again. I would say that one of the gearboxes was filled with oil, the other with grease (there was a discussion on this) The oil dripped out (in small amounts) of the seal onto the deck, so I refilled it with grease instead. Don’t know when you last removed the boom gearbox, but I take mine off every two years now to keep the outhaul shaft easy to free. Ian Ocean Hobo SN96 On passage to North Wales

Re: New gearboxes - painted or bare alloy?

Mike,
I would choose the paint. The gearboxes are likely made from cast aluminum which tends to oxidize much faster than extruded aluminum does. It also gets that unsightly white, chalky, aluminum oxide powder on it, not a nice uniform oxide coating. If you go with the bare aluminum you will need to clean it regularly to keep it looking nice. If you go with paint, you won't need to do any real regular maintenance other than fresh water rinsing until the paint fails. At which time you can remove the paint, re-paint it and begin the cycle again or leave it as bare aluminum for awhile, see what happens, and decide what to do from there.

Hi Eric, I'm ordering them new from Bonfiglioli Transmission in Auckland. They are 70:1 reduction gearboxes (VF44 P1 70:1 P63 B14). So from a cosmetic standpoint you recommend paint? Is there any other noticeable or problematic degradation? Does anyone know how long the paint lasts? Cheers, Mike Longcor SV Trilogy SM23 Opua, NZ

What make gearboxes are you using and where are you getting them? If you leave the gearboxes unprotected they will look terrible in a short time. I was considering having my gearboxes sand blasted and powder coated. Any thoughts on that. Fair Winds, Eric SM 376 Kimberlite

New gearboxes - painted or bare alloy?
Mike Longcor (SV Trilogy)
Hello everyone,
I'm ordering new gearboxes for the main furler and main outhaul. The units can be shipped with a bare alloy finish or with a 2 pot epoxy paint. I'm curious if anyone has advice one way or the other. The paint will provide protection but will undoubtly fail at some point. The aluminum alloy should self-passivate and not continually corrode/oxidize. Any advice from experience? Any issues in running with bare alloy, besides initial appearance? I suppose it will look better than flaking paint in the long run. Cheers, Mike Longcor SV Trilogy SM23 Opua, NZ

Re: Amel 54 alternator belts
Oliver Henrichsen, SV Vela Nautica
Hello, I found this 76mm pulley for the alternator. I will call them asap to confirm that its for 8PK belts. I regulated the Alternator on my lithium system down to max 100A, that safes me from ducting air into its direction. Until now I never needed the extra 70 Amps but as my extern regulator is adjustable it would be posdible to raise the Amp output.

Hi Giovanni,
The standard belt is A46 The Carlisle Gold Ribbon raw edge cogged belt is AX46 The A section belt is 1/2" across and 13/32" deep The AX belt is 1/2" across and 11/32" deep - helps it go around corners better. I'm not in Facebook so I can't view your video, but I did see video of the Medicane hitting Ithaca and it wasn't good. Cheers Alan Elyse SM437

Re: Main mast Antennas

On the 54 (at least) the two original antennas (vhf and fm/am) look physically the same but are tuned differently so are not interchangeable. The type is written on the antenna itself. On our 54, the vhf was on the starboard/front of the mast. Thomas GARULFO A54-122 Moorea

Miles, Thanks for the test strip idea. Fair Winds Eric Amel Super Maramu #376
From: main@AmelYachtOwners.groups.io [mailto:main@AmelYachtOwners.groups.io] On Behalf Of Miles
Sent: Sunday, April 19, 2020 10:32 AM To: main@AmelYachtOwners.groups.io Subject: Re: [AmelYachtOwners] Excessive usage of water maker membranes
Hi Mark, I once ruined a set of membranes by putting chlorinated dock water in the boat and then back flushing. Since then any shore water that goes into the boat first goes through a “whole house” filter that removes chlorine. To check this, I have test stripes that measure the amount of chlorine in water. The test kit is sold in tropical fish stores. My filters are over 10 years old. I have been told that the more the filters are used, the longer they will last. When I don’t use the water maker much, the TDS goes up toward 300. When I use the water maker for my total supply off-shore or in a very clean harbor, the TDS goes back down toward 200. I agree with the comments. I also run the water without pressure for several minutes when I turn it on to get all the fresh water from the back flushing out. I agree with Alan that the pressure with fresh water could be damaging. Regards, Miles s/y Ladybug, sm216, locked down in Le Marin, Martinique
