<DIV><FONT size=2> Hello guys, I talked with Michael Rudinsky
from Boca today, and he told me that he is still working on getting the rear
bearing for the 3M 170. Although it looks like Tom Collins from Buyrc will
have them available soon. I will let everybody know when Boca has them
available as soon as I find out.</FONT></DIV>

<DIV><FONT size=2> I talked with Michael Rudinsky from Boca
Bearing while in Toledo. He did measure the bearings in my 3M 170
engine. The frt. bearing is the same as the frt. bearing for the O.S.
140 RX. Michael told me the rear bearing is a standard size, but they do
not stock it. Michael told me that he would order some and call me when
they came in. I have not heard from him yet. I will call him
tomorrow and let the discussion page know what he came up with. In
Toledo he also told me he would be able to offer the bearing in the ceramic
version for those that are interested.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> On the installation of the 3M 170 engine
question. I installed my engine on a Hyde ARI (A) mount for an O.S. 140
RX. It was a direct bolt in deal. The exhaust clears the mount
with now problem. The 3M engines use an o-ring manifold that
the header attaches to, just like the O.S. You can use an O.S.,
Harori, or 3M header on the 3M manifold, and will all clear
the Hyde mount. The only difference between the 170 and the O.S.
140 dimensionally, is the 170s cylinder is slightly taller and larger in
diameter, otherwise it is all the same i.e. exhaust location, throttle hook
up, and fuel line hook up. The needle valve is slightly higher on the
O.S. than the 170, but on the 170 you can change the mounting angle of the
needle valve if needed to line up with an existing hole in your fuse if
swapping from a O.S. 140.</FONT></DIV>

<DIV>I can offer an answer for #1 only . . . .. . .</DIV>
<DIV> </DIV>
<DIV>Mike Darr had his 3M 170 at the Toledo show, the Boca person at the
show measured the bearings so they could offer replacements. I would call
Boca to see if they are available or when they may be
available.<BR><BR><B><I>GW <<A

<DIV><FONT face=Arial size=2>For those in the know regarding the 3M
170::</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1: I notice the rear bearing is a double back
ball bearing, I do not know what this truly means, but will Boca or the US
based 3M retailers have the replacement bearings available? Any
other substitutes? Don't want to be needing a bearing in the middle of the
season and be waiting for a bearing from Italy!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2. Same question as above but regarding
rings? Do the retailers like BuyRC, PlanesPlus, AeroSlave, etc, have
replacements in stock, or plans to? Again, I do not want
to be without use of an engine waiting on a ring or bearing from
Italy!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>3. Will the 170 be a drop in replacement for
the OS 140? I have heard the bolt patterns are the same, but what about
the position of the nose ring, exhaust,etc? Completely interchangeable
with no refitting needed?</FONT></DIV>
