I don't understand the felt wick thing. It seems to me that the wick would just absorb the oil, preventing it from diffusing into the pores of the bushing. ??

You maybe right about the wicks ...I stuck a temporary tube full of oil into the top of the tube and tightened the skinny through bolt up a few days later when it started to seep ...
I did away with the greese nipple also
 
Nippleless :)

I take the nipple out and squirt oil in using a small plastic syringe. Air can escape past the 'nozzle' so no pressure build up.
 
I bought one of these:

SKF

Remove the zerk fitting on the swingarm end, insert this, put a barbed fitting in the 1/8 NPT threads, attach a hose to it with a small funnel on the other end, fill with a small amount of gear oil and let it drip in at its leisure. Leaves me free to do other things, like drink a beer while watching the oil level in the funnel drop..or check tire pressure or..

No there's no wicks in there
Do you advise it?

I removed the swingarm from my bike after about 25 years for inspection/refurbish and found the spindle and bushings to be immaculate. Zero corrosion, zero wear. MKII with felt wicks and welch plugs.

Do you ride when the roads are salted ?
 
Can some tell me , if the gussets in the swing arm modification are , required to stop the stock design failing or just for added stiffness / stop flex ? .

If you are referring to the clamp modification...I believe some use it as a bandage to cure worn bushing movement
I installed it in the hope to stiffen the whole thing up better than new...AFTER I fitted new bushings and spindle...time will tell I surpose

It's to take the play out of the pin to gearbox cradle tube
The interference fit of the swing arm pin is not good
And the tube wallows out
Norton fixed this with the MK3 cotter pins

"Norton Service Release N3/42, April '73.

'
The Commando rear swinging arm has been stiffened by the incorporation of box section gusset plates, providing improved rigidity.
The new swinging arm completely replaces the previous component and was fitted as standard from Eng No 300,003.

Order 064539 in place of previous swinging arm 060441."

Very neat
Looks like his one dosent leek either!
Hope nobody spots that anti wet sump valve!

I dont know if I'd make a feature of it ...I would semi hide it like the oil stopper valve (nice spotting) and route it to the centre of the spindle tube like yours ...for even distribution :)
 
I found a method that works pretty well using a sports ball inflation needle connected to a wheel bearing grease syringe with a piece of tubing. Remove the zerk in the end cap, inject 140wt lube oil with the bike on the side stand.

So if the chain luber is rubbish , it could be converted to the swing arm luber !

The chain luber is great...it just needs a better regulator ...warm (reaction time) oil will deffiently speed up the possibility of a potential new leak...got me thinking now...cheers

You might need on of those stationary motor drippers in the line.

Old metal lathes like South Bend make use of industrial felt wicks to lube bearing surfaces and these bearings last multiples of decades .
