Scarlett, my 2014 URAL Patrol Sidecar Rig had developed a severe mechanical screeching noise whenever the clutch was engaged, especially when putting her into first gear. This noise had led to me aborting the ride up to the top of Pikes Peak last week.
BLUF: (Bottom Line Up Front): Scarlett's clutch plates were toast. Although a lot of the clutch material was still in place, the center spline "teeth" were gone on one and almost gone on the other. I am surprised I was able to ride Scarlett back from Colorado Springs at all!
First step was to separate the tug from the sidecar. No major issues here, and we found the bolt onto which the rear upper support arm bolts onto was loose. (This was fixed during re-assembly)
Here's sides of Scarlett one usually doesn't see in pictures.
Quite helpful, the above dolly...
On the bike lift, ready for the tear-down to begin in order
to get at the clutch plates.
The 2014 URALs don't have a lot of room between the rear of the transmission
and the front of the swing arm. Randy wrestled with removing the donut for quite a
while as he didn't want to move the swing arm backwards.
In the end, Randy ended up having to remove the engine mount bolts (supporting the engine from below using a jack and block of wood against the oil belly pan). This involved removing the gas tank, all associated fuel lines, the throttle bodies, the coil and the fuel pump. Quite the endeavour, there must be an easier way to gain that needed clearance.
Then, after we got the donut out, off came the air filter box, starter, clutch cable and clutch release lever and finally the transmission gearbox was removed, revealing the cover plate to the clutch pack.
Here you can see Randy applying heat to each Allen head bolt
securing the cover plate on the clutch pack. They come secured with
red Loctite from the factory now you see.
A special tool to keep pressure on the cover place as the bolts are
removed. There's springs, you see, keeping the clutch pack's components
under pressure, making sure they mate to each other.
Sorry for the blurriness. Here, Randy has the cover plate off, and
is removing the special tool from the clutch pack so he can pull the pack off.
Lots of clutch material and crap remains in the flywheel,
it would be cleaned out of course before the new clutch pack was installed.
Above is the clutch plate closest to the flywheel. As you can
plainly see, the "teeth" that should be there are completely gone.
Above is the clutch plate closest to the transmission.
You can see the pointy remains of that used to be square cut teeth.
Above is the transmission input spline, some minor damage but it
looked OK to use to Randy and I. Note: it was coated with Moly
Grease by Randy before re-assembly.
Here's the new clutch pack installed and cover plate back on.
Randy went ahead and painted witness marks on all the
bolts so I can easily tell in the feature if they're coming loose.
Notice, the new clutch plate's square cut teeth, that's how they're
supposed to look.
The re-assembly of engine components went pretty well after we got the engine securely mounted up again. Next time the engine gets worked on at this level, I must ensure the fuel tank is empty, save on spilled fuel and mess.
We decided, after inspection, to re-use the donut. (We'd already put it in and didn't want to backtrack several onerous steps to put in a new one) I really must learn if moving the swing arm back is easier to do than moving the engine forward. Donut replacement is not easy due to space constraints!
I'll be closely monitoring the donut over the next few rides.
It was 7:35PM when we fired Scarlett back up and heard NO NOISE coming from the clutch area! Success!!! A short test ride and it was time to put her back on the trailer for the ride home.
My sincere thanks to Randy for doing this work and staying late to get it all done last evening! It made for a really long day for all involved.
Mileage at time of clutch replacement: 17,138km.
All work done under warranty coverage, there's apparently been a couple or more cases of the clutch plates failing the way Scarlett's had done. Yet another example of the great support provided not only by my dealer, Unique Rides of Fort Collins, CO but the great warranty coverage and support by URAL and IMWA!
