CLARIFICATION/UPDATE "Crankcase Stud Bulletin"
Posted: Mon Mar 03, 2003 12:19 am
I've spent the last few hours plowing through the bulletins and service manuals for the Cannondale. While examining the pictures on the Cannondaleriders.com web site.
We clearly have two issues here, not one...
#1 We all know that there is an update for the Crankshaft Cartridge Plate. This replaces the Crankshaft Cartridge bolts with studs... This plate is in the "front" left hand side of the engine shown best on page 104 of the Service Manual PN 941-5002037.
Many of the newest machines have had this change implemented and one can clearly see one of the studs used to secure the back of the crankcase cartridge plate when removing the clutch basket. Cannondale 27 gave us a great picture of this. This picture is located on page 5, post 5 of "Check your Engines..." thread. In the picture the stud is located in the upper left hand side just below an allen head bolt that is securing the transmission cartridge plate (see the two different cartridges here? The one in the front is the crankshaft one and the one toward the back behind the clutch basket with all the allen head bolts is the transmision). The crankshaft cartridge is what all the talk is about. But thanks to moto440mans pictures we also have a second issue...
#2 The second issue that we are dealing with is best illustrated in the pictures left by Moto440man in the "check your engines..." thread, but on page 1 posts 2,3 and 4. These pictures clearly show multiple bolts backing out of the "transmission-cartridge-plate" as well as having one visible bolt missing from the "crankshaft-cartridge-plate". The transmission cartridge plate is located on the same side of the engine as the crankshaft cartridge plate but the back half of the engine directly behind the clutch basket. The transmission cartridge plate is best shown on page 142 of the Cannondale Service Manual PN 941-5002037
So, not only are bolts backing out of the crankcase cartridge plate but they are also backing out of the transmission cartridge plate. Moto440man's pictures clearly show this.
NOW FOR THE QUESTIONS...
Why is there no bulletin on the transmission cartridge plate bolts backing out? Is this caused only when the crankcase bolts let go? My 03 has the stud update on the crankcase but I have the same allen head bolts on the transmission cartridge plate that backed out on Moto440man.
If we are to check for the crankshaft cartridge plate stud update are we to pull out the allen head screws in the transmission cartridge plate and red lock-tight them while we are there? This is a large concern of mine!
What do we all think of this?
:eek: :eek:
