Oil Pipe Junction Block upside down

I did something similar to Jim, but with both hoses routed downward, to accommodate an oil cooler on my PR back in the '80s. Worked fine.

Joachim, like I said a vary nice clean look. I think the Norton logo on the timing cover looks nice in black too.

Where did you get the finned points cover ? ( and the wireless plugs):D

Cheers,

I may be wrong, but I suspect having the oil lines going upwards may have better matched the inlet and outlet of the first model's oil tanks (the first Fastback, Roadster and S tanks) and they of course didn't have the external spin on filter either. I think Norton just didn't rethink it when they changed the configuration of the oil tanks and added the oil filter. For later models with the oil filter it looks way better with the lines tucked under the gearbox and it's certainly how my Mk3 will be plumbed.
 
Some of the earlier Norton twin models had the oil lines going downwards. I don’t think there will be any issues with this.
 
The only possible 'issue' that I can see would be related to whether it affects gearbox removal as far as clearance. And since gearbox removal is normally only done in a complete teardown, it doesn't really matter at all. Oil flow is unaffected since the "head pressure" of the oil reservoir to the pump is identical regardless of which direction the tubes are facing. How fortunate that water (and other liquids) seek their own level! Well, fortunate unless you worry about wet sumping! :)

yes for a cleaner look I did the same but made my own alloy "pipe". I also reconfigured the fittings on the filter headView attachment 13655

Don, tell us a bit more about your bike, er mods, i see a cable on the right footpeg which looks like a brake cable but no kickstator or shifter... so is yours a mk3? also really like the red frame makes it pop out much nicer than a black one.

I'm interested in what and where is the ignition system. Magneto?
Possibly another thread.

The finned points cover is from Donald Pender. Forget about the wireless plugs, they dont work well in our Aussie dry climate. They need high humidity.

No gearbox adjuster, so at least a MK3 primary with chain tensioner.

only MK3 parts are the inner right side shift cover and its shift shaft. cNw elec start inner primary cover (modified) and pre MK3 outer primary cover (modified) Crankshaft mounted Boyer (modified)
 
Went out and looked at my Norton...the black hoses pretty much blend in with the black frame so frankly, to my eye there isn't much visual difference in reversing the oil tubes. Glad I took a look - saved me some work! :)

View attachment 13692 View attachment 13692 When I decided to do the Black Cat build I wanted a clean clever look, this is one of the things I didn't like about the Norton's was hose locations up & over the transmission..... I just figured it had to do with lessons learned from racing . I have friends over at Cape Canaveral that hooked me up with high temp hose protectors, which was my only concern was heat from the exhaust... It's basically pretty simple 1 day job...Reverse the alignment boss torch & pull out the oil fittings re-bend cut down the metal tubes, my set was all brass so it had a hose barb setup which was de-soldered & re-solder. the biggest thing is to thoroughly clean the parts which I soaked the parts in acetone overnight for best results.....I also used a heat gun to retrained my crankcase breather hose to follow my motor brackets & have put about 300 trouble free miles with not a trace of any oil leaks since bringing it back to life... the only thing I see is wet slump which allows my oil tank to drain into the motor case after about 2 weeks, which is actually why I'm on this forum today, to read past postings about that problem

Don't erase our history, Learn from it..... Deplorable

Re, "wet sumping" may be caused by you having Commando timing cover (that engine was inclined forward) I may be wrong but on a "vertical" engine doesn't help.
 
I had a Commando engine bolted into an Atlas frame many decades ago. I never had any sumping problem, but I rode it constantly so there wasn't much time to wet sump. (Constantly is a relative term since it was down for repairs at least every few weeks...).
More likely the oil pump could stand some attention.
 
Oh, and Merry Christmas Everyone! I actually have a life and am waiting for the youngest grandchild to wake up.

Matchless G15/N15 had the lower routing from the outset, as did the G12 twin. The P11's junction block and hoses were routed as Atlas/650SS/Mercury - this may have been a case of rationalization wrt. spigot for the junction block and the junction block itself. I concur that the lower routing looks much cleaner on the Commando and I will adopt it for my Mk3.
