Subject: RE: Clutch weirdness

Hi Joe,

Good catch on the part numbers...I just checked again and all of the
spare parts catalogs (v700, Ambo, Eldo) list the same part for both
spacers: 1242 9800. Mine are clearly different. I'll have a close look
at them tonight after work and take some pictures. Very curious.

I can see that short springs could cause a dissengagement problem...if
they were just short enough, they might provide just enough pressure on
the discs. But, might not push the intermediate plate forward enough to
allow the pushrod to dissengage the clutch. The Guzzi clutch discs are 8
mm thick when new and are supposed to be replaced when the get down to
7.5 mm thick - leaving only 1mm of allowable wear. There's probably a
little more slop allowable in the system, but probably not too much
extra.

Gregs,
As I recalled, I used the same spacers that came with
Junkyard (71 Ambo) to mount the 850T 5-speed into it's frame. I checked
my Eldo parts manual that I had previously downloaded from Moe's site &
compared it to the 750 parts manual, 2nd edition at This Old Tractor.
Both parts manuals show the spacers as identical left & right, and both
machines share the same part number 1242 9800.

Kev- don't quite follow how short clutch springs
wouldn't allow the clutch to disengage - sure you didn't mean springs
that were too long, coil bound, preventing disengagement? Wouldn't short

springs apply less pressure to the clutch pack, allowing the clutch to
slip?

Sounds like someone used 4-speed spacers with this ELdo. More wierdness.

Forgot to mention, if you need "official" measurements, I can take the
bolt out tonight and let you know what they are. Just let me know.

Ah ha! I originally thought you were referring to the alignment
spacers
that fit in the bellhousing so that the alignment of the
engine-transmission is not completely depending on the studs.

But now, I see that you are referring the aluminum spacers that fit on
either side of the transmission, through which the large transmission
mounting bolt is slid.

I just measured these on my Ambo with a 4 speed...still mounted, so
they

are close, but not *perfect* measurements:

Right side = 42 mm
Left side = 57 mm

I don't know what they should be for an Eldo with a 5 speed, but I
thought I'd toss these numbers out, anyway. Perhaps something got
switched at some point in the bike's life???

5. As long as the transmission and engine mate properly, I don't
suppose
there is anything wrong with the trans spacer being longer on one
side
than the other...perhaps it just worked out of the aluminum case?

I figure the frame must be bent or something. Complicatd greatly my
efforts to get the swingarm aligned with the tranny output.
