Battery Carrier

on several posted pictures here I have noted that the crutch cable goes through a hole on the corner of the battery carrier????? Is this on certain models only????

Crutch cable? Got a part number for that one?

Clutch maybe, mine disappears down a dark abyss on the right side of the battery box.

under official oil pipe routing in the search facility is a picture of the cable going through the front right hand corner of the battery carrier...if only I cold paste the bloody link!!!

If the cable were routed through the front right hand corner of the battery carrier there would be a tremendous kink where it enters the transmission. That would create a terrible bind and so much friction that it would take two hands to pull the handle!

Olympus, is this the link you were trying to post? Click on the #16 (for a particular post in the thread. next to the Like link) to get a "permalink" which you can then cut/past.

I see now why my cable isn't routed this way. There's some sort of bushing in the battery tray with a smaller ID than the OD of the transmission end of the clutch cable. Still works fine and feather light pull. I see by the photo above that there is no such bushing, perhaps one of these days I'll see about making a change to my setup.

Yes that the link Peavey.. thank you
Scroll to one of the last photos & it can seen that the cable goes through a drilling in the battery carrier.
I plan to put the carrier in very soon, so I'll check all the angles for best cable routing, and I'll decide then if it's best to drill the carrier

Whoa! I'll have to look at mine, definitely doesn't go through a hole like that. Looks way wrong to me.

On all commando the clutch cable goes just to the rear of the oil tank/battery tray right hand front bar, and just in front of the isolastic. This is the same for all 3 oil tank mounts fastback, central and roadster.


Granted the cable was originally sent through the wire loom grommet in the down tube web. I will not do this no way- no how....I always lay the cable as shown in the frame pix. Exactically where the 45 deg tube meets the backbone tube. This is the ONLY place I tie wrap the clutch cable. To me this routing is religious and takes priority over all other obstacles. In the roadster application it goes BETWEEN the oil lines. S1 Fastback the cable runs within the tank gap.... easy to see.



On pix 16 on the other thread it looks to be a roadster tank on a fastback battery tray. But even on his bitza I would still run the cable between the hoses and cut the tiewrap.

What is new with S2 version...
S2 Commando has new "roadster" oil tank/ with a big battery tray,
What S2 version uses 2 big 6v batteries...and lots of extra wires that people curse endlessly.

S2 model...interpol !

Please disregard and put your small battery there.

Looking at the battery space specifically on the roadster carrier (far right), why is the space so large.... were the OE batteries of the time a lot larger and lower amperage so needed to be?

It was the factory's intention to fit a starter motor from '71 but didn't get around to it (until the 850Mk3) but it seems they couldn't be bothered to make it work reliably so gave up (hence the starter motor blanking plate, ballast resistor and 6V coils fitted in readiness from '71).
A starter motor would certainly have needed a bigger battery.

Forgot about the failed 71/72 starter... Who knows how bad the 1st version actual starter mechanism was.
I have started my MKIII with my starter with the tiny atlas battery, the regular small commando battery too. The constant search for the big battery upgrade is evidence that the learning curve is slow. That is when I learned how incapable the original single phase 180w alternator was to keep UP the charge recovery on ANY battery. IMO even the 3 phase system is not great.

There's an amusing account written by Bob Rowley in Mick Duckworth's 'Norton Commando' book of exactly how bad it was!
It seems they didn't bother to include an anti-backfire device in the starter drive or, at least not one that worked. If the engine kicked back the starter drive would often self-destruct, wrecking timing side case as it did so!
