"Norton swing arm lubrication"


  

          

I'm not sure how best to apply 90 wt gear lube to the grease nipple fitting on the rear swing arm cap of my 1971 Commando Roadster. I assume it should be done under pressure, hense the reason for the nipple? Every piece of literature which I've seen describes 90 wt, not grease, but how should it be dispenced? Since I can't find a grease gun which holds a liquid, I'm perplexed.

thanks,

Hi Bob,

Here is how I've been doing it:

I put the gear oil in a pump type oil can. Loosen the center bolt on the swingarm cap slightly, and you can rotate the fitting up to the 12 o'clock position. Tighten the center nut back up, but go easy on it. It's delicate to say the least. Then, remove the fitting, lean the bike over to the left, and pump it full, and replace the fitting ASAP. All of this assumes that it is not full of grease. If someone has pumped it full of grease, you will need to pull out the spindle, and clean out the center, and the two small holes in the bottom of it. Not unusual to find that somebody has done this, but hopefully, that won't be the case for you.

Hi Bob,
I believe the manual actually calls for 140wt oil which is somewhat hard to find. I have heard that some have found it through tractor supply stores. However I seriously doubt that the use of 90wt will cause any problems. I am also pretty sure a grease gun will pump liquids, probably a somewhat messy affair. I have read where some have gone to their local animal feed stores and purchased those plastic syringes, then removed the grease nipple temporarily in order to inject oil into the hole.

justa thought,

A standard grease gun WILL pump gear oil 90w, 140w. I had bought a economy grease gun and demanufactured the rivets holding it together, and reversed the body in the handle assembly to hold the cartridge UP. I now pour in the 140w, that I get from the Airens snow blower dealer.
By changing from the brit fitting to the american zerk style, it easily connects and fills.
I originally did this mod for early Lotus Elan front end trunion lubing which likewise uses gear oil instead of stiff grease.

I usually remove the bolt that holds the pivot pin and drip the oil in there with a oil can. No chance of breaking that spindley little bolt that holds the end cover on.
