CMW sells the Sprag Clutch Assembly PN570153, it has more components than just the Sprag Clutch and goes for $339.95 as of this morning.  I find some sites that sell just the sprag clutch PN 560011 for about half the price of the assembly.  It says it fits all ES 500cc, can anyone confirm that 560011 with fit a UCE?

Sound about right, mine was in the $300 range.  I don't know whether the other cheaper ones would work though.

Because Royal Enfield redesigned the sprag clutch I would be leery of buying a new clutch from sources other than Royal Enfield or one of their dealers.

With my luck I would end up buying one of the old trouble prone clutches that had been superseded.

The sprag itself is rides between the inner and outer gears.  You get those two gears when you buy the whole unit from RE.  If you just replace the sprag you may still have trouble because the surfaces it grabs on the inner and outer gears may not be smooth.

You can see here one gear is 24, no numbers on the sprag or the other gear, just 25 for the whole shebang.

I have seen those sights also.  I wonder what the P/N for the sprag clutch is for the AVL and iron barrel?  Hopefully one for the UCE is a little better?

Yes I think my Sprag Clutch is gone.....

What made you open your crankcase to see if it was broken ?

I wonder if your bike is covered under warranty or is it past the time ? Anyone with these older and weaker sparg clutch, if broken, should be given a free upgrade.

That'll buff out.

My bike had been making alarming noises while starting.  Then it would not crank over the engine any more.  The starter would engage but no thump thump thump.  I push stared the bike a couple times to make sure it still ran OK.
I called CMW and I'm a bit too far outside the 2 year to cover this (9 months).  The parts guy was unavailable at the time.  They couldn't tell  for certain if I purchased a new sprag clutch assembly that it would be a newer stronger type or the legacy weak one.
I sourced just a sprag from a German manufacture, it hasn't arrived yet.  I'm going to try replacing just the sprag before shelling out the $330 for PN570153.

The weaker one was distinctly different from the stronger one (at least when they are intact).

Who is this German manufacturer and are you sure it will fit your bike ? You don't want to get something that does not fit right.

The maker is Stieber Part DC 4127 (3C) I measured the pieces of the sprag as best I could.  This part was cheep enough I was willing to gamble that it fits before I shell out for the exact same part that failed within 8k miles.

Do as you will, but replacing just one part of the sprag is usually a bad idea. They typically don't last that well. A sprag failure in a UCE is not a common event.  It is also one heck of a lot easier to replace, The newer the part and the more certain you are of its heritage the better,  There are some BS sprags out there. I can't tell you how to tell other than to be careful of your source. The reasons for a sprag failure in a UCE bike it totally different than the failure in an iron barrel or an AVL.

[JesterNT]

The Stieber sprag fits, its exactly the same size.  In fact it appears to be identical in every way, so I dont know if it's any stronger than OEM.  My sprag must have been slipping for a lot longer than I noticed because I'm surprised how fast my C5 stars now.  I'll have to see how long it lasts.
