Out-haul gearbox for SM2K


Stephan Regulinski
 

To all SM and SMM owners:

To revisit the subject of the out-haul gearbox and update details, I called Leroy Somer in the USA and spoke with Mathieu Herieau who told me:

1. Justin is no longer in this position, he has transferred elsewhere within the Emerson Electric group.

2. The gearbox number within Leroy Somer is MVA M33C with a ratio of 60. Mathieu told me that the number "102014" is not a number used within Leroy Somer. The part is manufactured in France and distributed in the US by someone in South Carolina. I will update the contact details after Mathieu responds to my inquiry so you can contact the right person directly.

3. The bronze gear, which is the gear that will take the majority of wear (after seals and bearings), is handled by LM Electric in Montreal. I have not contacted them yet, but will provide contact details if they are willing to source the part.

4. Amel's last purchase of the gearbox appears to be a batch in 2006. I have not contacted Amel to see if they have any remaining in stock.

5. However, Amel purchased a batch of the bronze gears (Mathieu called them "wheels") in 2012. Again, I have not contacted Amel about current inventory.

6. Mathieu, while looking at the computer notes, observed that Amel had certain modifications to the stock gearbox made: stainless bolts to close the case, special paint on the housing, an adaptation for the connection to the electric motor. The adaptation to the connection to the electric motor is the only issue I see to using the stock gearbox. Replacing the bolts with stainless is straightforward as is applying suitable paint.

On reflecting on this information and talking with my local machine shop, I believe that it would be easier and possibly cheaper to overhaul the existing gearbox rather than replacing it, which would require separating the gearbox from the motor.

If the bronze wheel can be sourced, then the bearings and seals are standard industrial items. The only other serious wear item is the top half of the case, which tends to corrode from salt water sitting on the top around the seal. After significant corrosion, the seal will no longer seat properly. A poorly seated seal simply accelerates downstream problems from salt-water intrusion.

If one has the parts, any half-way competent machine shop can disassemble the box, pull the seals, bearings and bronze wheel, replace same, and reassemble. In fact, an Amel owner could probably accomplish the same with access to a gear puller to take stuff apart and a press to put it together. Given that the key to a successful overhaul is the bronze wheel, however, I would think that using the sledge hammer (recommended by some for removing the output shaft from the gear box), is a less than elegant solution.

If you have the gear box in pieces, this would be a good time to add some grease ports. Posts elsewhere discuss this.

Finally, inspection of the bronze wheel shows just how much wear it takes when one does not relieve the load on the main sail before furling or unfurling the sail. I would think that you could get several decades of service from the gearbox if the sail was never furled or unfurled under load and the gearbox were splashed with fresh water after every sail. The ease of pushing a button has removed the feedback loop so we never really appreciate how much our equipment works.

I finally reached someone in the US who is responsive and appears to be able
to source the gearbox. I haven't actually ordered yet as we are overseas and
need to figure out timing etc.

Mark,

The gearbox is available. Pricing is $521 ea. FCA Charleston, SC and
delivery time is about 8 weeks.

The product would be available from the factory in France in 4 weeks if you
wanted to air freight the item. It normally costs about $3.50 per kg.

If you want to proceed with an order, I can put you in touch with one of our
distributors.

Bill,

This is the alternator division of Emerson electric that handles Leroy
Somer.

When I called the number they said that they do not handle the
gearboxes.

Do you have any other info?

Would you please email me your correspondence with them.

Eric and all,

The Leroy Somer gear reduction gearbox is part number 102014. It can
be
ordered from Leroy Somer at the US phone 731-967-3000. I got this
information from gears-usa"at"leroy-somer.com. They told me via email
that
it was available.

I have not called the number for a price because I am in Greece now.
Let
me
know if this works out for you.

Best,

Bill

It seems like quite a few people are tackling the problems servicing
their
outhaul gearboxes. I happened to notice the other day that the top
lip
seal
was shot on mine and started on a two day project to disassemble the
gearbox.

I tried just about everything to get the inner shaft removed, except
"getting medieval with a sledge hammer" as one of the other owners
demonstrated. After bending several 8mm steel brackets and breaking
my
puller tool, we finally succeeded with a 20mm thick steal bracket
that
was
fabricated for the purpose. The nice thing about the approach that
finally
succeeded for us was that all the force was placed on the outer
shaft of
the
gearbox, none on the boom or the other components of the gearbox.
I'll
post
a picture when I have a chance.

I found the model information posted by one of the other owners
here:

Manufacturer: LS Leroy Somer
Made in France
6015 Angoulene
Reducteur N 0256889
Type MVA M33C
Rduction 1/60

I have not been able to reach Leroy Somer via their contact page.
Can
anyone
recommend a reliable and inexpensive source to order the gearbox or
parts
from? Any pricing info?

One other question: it seems that the outhaul gearbox causes more
problems
than the main sail furling gearbox. Is that right? Is the latter
just
less
exposed to the elements?

thanks, Mark
