Update on Bean Can Project - so far "no beans"

In the middle of dis assembly, my friend Niels wife had a car accident - wife is okay but cars seems to be totalled - doesn't take much to total a car these days - we'd  just removed the umbrella that spins around the Hall sensor.  We left off with a "C" clip on that was holding things together - we'd removed and not lost the tiny pin that secures into the shaft.

Yesterday we picked up where we left off - Niel is a retired mechanical engineer and quite talented for sure!  He hooked up a oscilloscope  to see if the Hall Sensor was working - so when it was hooked up to the scope, we had a vertical line and when we interrupted the signal, the line moved to the right - seemed to indicate the Hall Sensor is okay - it looked okay too - not broken or burned.

We cleaned, lubed & re-assembled but a little round spring at the bottom of the can where the shaft goes through came out and Niel thought we'd be okay without it seemed impossible to get it back in.
When I got home, Niel called to say there was a leftover "C" clip on the work bench - I'm sure it has to do with the umbrella and the little pin where the Hall Sensor resides - no wonder the bike wouldn't start - she popped a couple times but that was about it - I pulled the bean can and now know there's a missing clip that I'm sure is important!!!

On top of that, the connector pins are suspect, which I really should have checked before going into the bean can but I was "curious."  No problems as always an educational experience and good fellowshiip working with Niel.  

Though the Hall Sensor seemed to test okay and we also tested the new one, Niel was reluctant to drill out the new one and replace - BUT we were in that far anyway, maybe we should have for good measure or just added it to the other side to have a spare sensor, which makes sense to me.  So the R65LS is currently grounded until further notice.

A part of me is interested in buying the Alpha Can from Rick at Motorrad but 350 is a lot of shekels. Another part of me says buy a used one on Ebay but those go for $150 and who knows if they even work.

Wondering about your thoughts on continuing with this bean can, buying a new one from Rick, or a used one?  Also, where can I buy a new connector as the one I have is in really bad shape.  To add insult to injury, the wires coming off the Hall sensor are Red, Green and Black and the wires coming off the harness from the bike are different colors - crazy!  Trying to get this sorted out as many of you know, it is not a good feeling when your bike suddenly conks out and leaves you stranded!

Will report back, as we resume next week.  Stay tuned.

The "little round spring"... Are your referencing one of the two advance weight return springs?

"A leftover C-clip on the work bench"... Perhaps the clip that holds that 'little round spring' on its post?

Gotta replace both items. If you have a wheelbarrow full of patience, the spring can be replaced by working through the oval metal cap's opening. I can assure you that it is a tedious exercise. The c-clip, nope. Gotta open the can. You really wouldn't want a loose bit of hardware jamming up the bean can's shaft and transferring that energy back to the drive slot in the camshaft! Double Argggh!

Problem with checking the Hall sensor on a scope is that it cannot replicate the random heat failure that can cause the sensor to go Tango Uniform until it cools off and begins to repeat the failure mode cycle.

Georgestrait, our forum member in France, knows of a Euro available connector that will get you going.

Unless you wish to spend the $350+ with Rick or gamble on a used bean can and replace the sensor in that old/new unit as did I, suggest you gird your loins and re-address your existing ITU... since you'll already be inside to replace that little round sping and leftover c-clip.

Thanks Monte - what does ITU stand for?

Also, the round spring I'm referring to are not the 2 little springs that attach to the arms that move - this spring is a larger spring on the end of the can where the dogs go into the crank - thinking spring was meant to keep the can sealed - that's the spring that we can't get back in the can.  Is the spring essential and other question where would we find a replacement?  

The leftover "C" clip is @ 5/8" diameter.

I bit off more than I can chew on this project  :-/

Run through Daryl's photo essay again. I think you are referring to the spring that wraps over the steel pin which secures the cam drive dog ears. It's purpose is to keep the pin where it belongs. It's on the outside of the bean can.

Here's another good ITU overhaul photo essay:

It looks like a spring you'd see in a seal used for axles - not the spring over the shaft & pin by dog ears.

IF I went that far in and had a replacement HALL sensor, I'd go all in and replace it.    You *might* get luck and get the Hall sensor unit to fail by applying some heat to the unit while it is on the bench and hooked up (it would be intermittent, so you might have to also spin it with a low speed drill while it is hooked up to an oscope (that one in your picture is a classic antique scope, alright) while you blast it with a hair dryer.. or it might still appear to work OK under these conditions as the heat might not be as hot, and there will certainly not be the vibration added to teh mix..

Hi Mike and thanks for your reply - there's an Airhead tech day tomorrow - since the sensor is suspect and we left the C Clip out, we're going to tear it apart again and see if we can R&R sensor & get all the parts back where they belong.

I did order new connectors between end of bean can and bike from this place: The OEM connectors on my bike are awful!

Hello !
The link you gave is for the housing only. You need the 3 pins, and the protecting boot also.

[Red_Hen]

Thanks, George - I believe this is the female connector:

[georgesgiralt]

No.
The one in the link has nothing in common, except the 3 way ...
Here http://www.kabelschuhe-shop.de/Connecteurs/Connecteurs-AMP-JPT/AMP-JPT-Set-3-pin-05-10-mm-%B2::7983.html?XTCsid=645391f4g24tcl2tcnlii21qt3 you'll find the 2 connectors. On the left the male and on the right the female.
They are the new version where the locking clip are built in the female connector. They also lack the boot making them properly waterproof (but there are the blue seals to put on the wire).
I've ordered twice from the Kalishop German site. They are fine and deliver the goods fast. But I'm in France and protected by EU laws. So YMMV ...
If you have to reach a certain basket amount look at their wiring products. They have wire splices I've never seen elsewhere.
Hope this helps.
P.S. : I forgot to mention that the pins require a special die on the wrench to be properly seated on the cable. I had success (so far) soldering them but you need to work properly in order to be able to insert the soldered pin into the receptacle and locking it into place... (my cable wrench can't get the proper die so the whole would cost me my first born just for 3 pins in the foreseeable future...)

Thank You, George - I'm making use of the existing connectors for the time being.

I attended an Airhead Tech Day today and got help replacing the Hall Sensor - wow - what a job!  

The good news is, my R65LS is back in service!  I held my breath all the way - it's quite a tedious process, especially the R&R of the sensor - after breaking a couple drill bits trying to drill out the rivets, we used a grinder and ground them down - bike is running great!  

Thanks for your help & encouragement.
