Charging problem

[msbuck]

BTW, the stripped threads are on Graham's bike ('81 R100) - and he was doing me a favor.   [smiley=sad.gif]

Ok, so we moved the battery negative cable to the rear bolt that attaches the coil.  The cable was just exactly the right length to reach. Then he cleaned up the threads, used a little aluminum foil to get the bolt started and then slithered a little JBWeld on the outside washers/bolt head to hold it all together.  It looks ok and seems to work.  We'll see...

Ick!  That sounds like a nasty bodge...

Eventually the transmission will need to come out so you can either re-tap for a size larger, or attempt a heli-coil fix, which I hear can be tricky because of the limited amount of material and whatever is right behind it on the inside.

Poor Graham... trying to help someone out...

Another save by JB Weld! [smiley=thumbsup.gif]

Shoot, I'll bet it's no more ghetto than duct tape on a seat. Doubt anyone will ever notice it. Ride on.

Yeah, that's how Graham feels about it as well.  At least the bike is road worthy at this point.  You're right, when the transmission has to come out for something else, he'll probably take care of it.

He just likes things to be right.  Shame on me for not taking notice of those little washers...

If I don't take pictures when I take things apart, I at least draw pictures and take notes.

shame Shame SHAME!

First off, don't ever touch that hollow breather bolt - disconnect the negative lead at the battery instead!

Secondly, the battery cable can be moved to one of the trans cover bolts a few inches to the left. You'll need a long hollow washer or a stack of them and a longer bolt to attach it. It's a good idea for the negative lead to connect to the engine because the path from the starter to ground needs to be as short and direct as possible.

I once 'fixed' those tranny cover threads by crafting a metal piece to look like that black plastic spacer the speedo cable fits into. Instead of a slot, I drilled and tapped the spacer to accept the breather bolt. Works great!

It's amazing what you can do with a metal lathe, isn't it!

A friend made this cap for me, since I use my GPSr for a speedometer, now:

The Vapor (instrument) users here might want to consider one of these.

I want one of those.  If I had the specs my buddy at work could make it.

Just take him the black plastic piece.

Sweet bit of machinist bling there. My tach cable hole is filled with a rubber bung plug; size matched and installed with a deft touch o' the mallet.[smiley=smash.gif]  No JB Weld required...

This is where I got the idea, from Stephen Bottcher's GS' "Ultra Vent":

Rob, does your plug extend as far down in the hole as the black plastic one?  And do you have a bolt there at all, or is your plug just a solid cylinder?  I'm wondering about how yours is vented.  

[Rob Valdez 79 R65]

Mine is the same dimension, inside the transmission case, as the black plastic.

I had the machinist (an airhead guy) cut a slot on one side to accept and trap the original vent screw, which is still my vent.

Stephen had his vented out the top so he could put a hose on it and run it up under his fuel tank.


He also created a similar vent for his final drive.  This is all for deep-water crossings.
