Poorly NF in Guzzi hospital...

NF gone for MOT and check over.
And having oil line to valve stuff, for piece of mind...
And I thought a grease nipple on swinging arm / check might be
sensible....
Not quite what I was expecting.
"....made a start on your Guzzi today, decided to look at the
fitting of a grease nipple as you requested, removed the rear
wheel etc to remove the swinging arm and i discovered some
movement in swinging arm to frame mounting, what has happened is
the swinging arm bolt has seized inside the main bushing which
has seized inside the two outer bush's, this has resulted in
wear at the mounting points on the frame as suspension movement
has twisted the mounting bolt back and forth wearing the
mounting holes. After 3 hours of trying to get the bolt out i
ended up having to drill the bolt from either side to release
the arm from the frame, it then took 14 tons pressure on my
press to release the main bushing from the swinging arm. I have
ordered a new bolt but bush's and the main bushing seem to
unavailable but i will keep trying, if i have no joy i will get
a new main bushing manufactured and ream the two outer bush's to
size, i will also take the two damaged mounting holes out to a
uniform size and machine up some top hat bush's to take the hole
size back to standard. Regards...."
Fingers and toes crossed!

More news as the Guzzi in care.
My man reports: "...new swinging arm bolt and the main bushing
looks reusable now i have cleaned it up providing i can remove
the original mounting bolt from the centre, currently waiting
for a longer drill bit to do so...."
Small steps.

Sounds like you're making some progress Mark. Do you know any of
the bike's history? i.e. how long it's actually been on the
road?

The bike was reported to have been used in service before
retirement (possibly Vatican) and then sold by a dealer in Italy
and regular use.
It then migrated to UK and came to me via NLM in Leicester.
Doesn't appear to have been restored, and has patina of
age...had gone in for service and MOT.
After a Vtwin Guzzi suffered with a drive shaft bearing and
swinging arm wear decided after reading Paul Fridays notes maybe
a check and grease nipple to allow maintenance as 'she'
ages...Fingers crossed.

Well it seems the Guzzi is all done, waiting for its return.
Bank a bit lighter!
Mot'd and ready to be delivered back. No success trying to drill
the old bolt from the swinging arm bushing which meant a new
bushing had to be purchased along with extra labour to machine
and fit shims to eliminate some side play in the swinging arm.
The other issue was the gallant fight put up by the flywheel
refusing to leave the crankshaft to allow me access to the kick
start assembly, my mechanic finally won.
Wonder if it will return when the rains come...
Regards
Mark

Good news; as mentioned on FB, you don't need to remove the
flywheel to get the kickstart off. My flywheel wouldn't come off
when I broke the kickstart spring, and I didn't have the special
tool for the locknut back then. Resolved by removing the rear
engine mounts and tilting the engine forwards on the front mount
to clear the frame. Details on the Paul Friday files
download.... ;-)
