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

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?

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
