You'll notice that the CIMs those pictures have (instead of an 8 mm keyed shaft) a sort of small gear built into the shaft (if memory serves, it's a 25° pressure angle piece--very non-standard). This version of the motor (the Atwood AP801-001 motor by CIM) was supplied in 2002 only. It was specifically legal in 2003, but not supplied in the kit (the FIRST version of the CIM motor, FR801-001 was introduced that year). For 2004, the FIRST-CIM was supplied, and the Atwood-CIM is
no longer legal, per <R09> and <R70>.
Electrically, they are very similar (but not quite identical, if the specs are to be believed--I'm looking at copies of both), but mechanically, they are different, due to the shaft configuration.
Now, there are pictures of a what appear to be a different version of the gearbox on their website--
here,
here, and
here--was this modified version intended to use the correct CIMs? Or is this something else entirely? [
Edit: Looking at other photos, those
are something else entirely--they're for the winch.]
Also, note that per <R62>, to make the gearboxes kosher, they could have modified the output shafts on the FR801-001s to have the same profile as those on the old Atwood (this couldn't have been easy), but they couldn't replace it part-for-part (certain modifications are allowed, part substitutions are not).
(Note that they said that the problem of legality had been rectified by modifying the shafts, so I can't accuse them of impropriety--just of posting outdated photographs....)
And yes, this is slightly off-topic, and moot, given that the season is over, but it is of potential relevance to anyone hoping to build one of these systems in the future.
