New Clutch for Scarlett

The parts to replace the worn components of Scarlett's clutch pack arrived yesterday; minus the input shaft for the gearbox.  The shaft should be here Monday according to UPS tracking.

After reviewing the install videos made by fellow Uralista and friend: Darrell S., I was ready to install the clutch pack.

Link to videos:

Ural Clutch Install:  Part 1 and Part 2

Note: He mentions using Blue Loctite, it's supposed to be Red Loctite, he just hasn't updated the video I guess.

 The springs are in place, no need to use RTV sealant
or toilet paper around the spring base...just carefully seat the
springs and rotate till they hold in place by themselves.

 First in on top of the springs, is the
Clutch Pressure plate.
It's got indentations in the back to support
the springs.

 Using an old 650 Gearbox Input Shaft from the 
Bural Rig, I make sure the two clutch plates'
splines are lined up with the Intermediate Plate
between them.

Make sure the raised portion of the clutch driven plates face towards the rear of the motorcycle!

 Clutch Thrust Plate in position, two bolts
applying pressure to hold things in place.

The hardest part for me this time was making sure the intermediate clutch plate lined up even with the grooves in the flywheel.  You have to make sure everything is level and square by using light taps with a flat tip screwdriver so that the plate's splines engage smoothly with the flywheel grooves.  

Once that's ensured, it's just a matter of tightening down the two bolts in sequence till the thrust plate is almost flush with the flywheel.  Then you apply the red loctite to the 4 screws for the remaining holes and put them in.

Once the 4 screws are snug, they'll hold the thrust plate down so you can remove the two installation bolts, put red loctite on the remaining two screws and install them:


Below picture shows the splines of the two clutch driven plates are lined up nicely and I managed to also line up the venting holes to hopefully improve heat dispersal while in operation.


That's it, now to wait for the arrival of the replacement Input Shaft for the gearbox.  Once that's done, then it's just a matter of re-assembling the tug back together and see how things go.

Yagi's first sunset with me and another update on Scarlett

Yesterday evening, I rode Yagi the 2006 Yamaha TW200 Dual Sport over to my usual Sunset picture spot.

The clouds cooperated somewhat, Yagi does silhouette nicely doesn't she?



This evening, Yagi and I rode out again for the sunset but it was not to be....clouds rolled in and completely blocked the sun.

What to do, what to do?

Instead,  I spent perhaps 30 minutes riding in the dirt trails in the vacant lot next to the sunset picturing spot.  Not a large area but several trails full of ruts, bumps, rough spots left behind when jeeps and 4x4s rode through when the mud was flowing.

Yagi, did great!  She basically floated over all the uneven terrain.  By the second time around, I was actively seeking the worse spots to see how she did. 

It's been a while since I rode along, delighting in the ease that Yagi negotiated terrain that my R80 Beemer would have trouble with!  Or maybe, the Beemer would be fine, but the rider would have had "issues".

So much fun, no time for pics.  :)

Scarlett Update:

Parts have been ordered to repair the gearbox and replace the clutch components.  I'll be doing the work, so wish me luck.  

As to Scarlett's ultimate fate, still being debated in my mind.  I will tell you one thing, my Ural rigs will probably never be taken again on rough terrain....forest roads being the most difficult conditions I'll expose their clutch system.

Introducing: Yagi, the 2006 Yamaha TW200 and a Scarlett Update

Yagi: Japanese for Goat.

The Yamaha TW200 Dual Sport Motorcycles have apparently garnered a reputation for go-anywhere little motorcycles, not very fast (in fact I think a Ural is faster if you can believe that!), good reliability and easy to service.


So the name Yagi pretty much came to mind after some debate.

I'm thinking Yagi will allow me to continue riding those back trails and forest roads I so like to explore and perhaps even summit some of the mountain passes that have defeated my Urals in the past.



She's a 2006, and I'm the third owner.  She comes to me with about 7300 miles on her.  The original speedometer failed at 7266 and the second one may have to be replaced.  I started maintenance tracking assuming a mileage of 7500 miles.


Had to replace the left mirror mount (broken by PO's nephew when he dropped the motorcycle), have a new speedometer but the second one started working on my way home the day I purchased it.  Have mostly finished the 7000 mile services on it in order to familiarize myself with the maintenance operations and so far, pretty simple!

I added the hand guards and storage case, a voltmeter, cheap tachometer and tank bag.

On today's riding, had to switch to reserve at 98 miles.  Filled up with 1.4 gallons so MPG (roughly) is 71 MPG?
---------------------

Scarlett, my 2014 Ural Patrol sits with the gearbox out along with all the parts involved with removing said gearbox from the frame.  She needs a completely new clutch and associated hardware and the gearbox input shaft has to be replaced.  Sadness.  She most likely will go to the dealer in Loveland, CO soon to be repaired there and at IMWA (the gearbox) and then sold on consignment basis.

 The gearbox's input shaft's splines, pretty chewed up

Like the last time the clutch plates needed replacement,
 it's like someone used a lathe and grounded off
the splines that mate to the input shaft splines in the first pic.

Throttling back....

I am going to slow the posting of stuff on this blog way down for now....

Decisions to be made as to continued Uraling, a new way to explore off pavement, and just blogging in general.
