oil for 2 speeder gearbox

[willsleddon]

Gents, I have deccided to use two stroke oil on the 2 speeder because it is designed to burn and is widely available if on the road. I still need to lubricate the gearbox with another oil so was thinking of one of those lathe or steam engine brass flip top oilers that will at least be from the same period. I could get that to work and it wouldn’t look out of place. Or has anybody got other ideas? Thanks, Will.

Knowing the number of miles you are likely to cover Will, I think you might need a system capable of providing a better supply than one of those oilers. Also the oilers tend to lubricate one side of the gear better than the other – a better solution is a system with the later plunger which forces oil to the other side of gear to the feed. Either way you would probably need a separate oil tank – there are the small cylindrical tanks which fit under the saddle. I might have one in the garage – I’ll have a look.

I use a tank under the seat as Lewis has suggested, seems to work well although you have to bend down if you want to use it on the move. I nearly crashed once when I hit a pothole, taught me to wait for a  well surfaced road. I find sae 50 too thick, I have settled on classic 20-50 as more modern oils are supposed to give clutch slip but I don’t really know.

It’s the thrust bearing which is vulnerable but fortunately the high gear one is on the left near the supply line. Whether pumped oil would get to the RH side I don’t know, it’s obstructed by the thrust rod, oil might just find its way out through the drums. It would be nice to see oil seeping out from the RH side I must admit.

I changed to a different gear to get chain tensions more equal (see technicalities), the old one had done 1000+ miles and the thrust bearings looked fine.

If I am telling you what you already know, my aoplogies,

Thanks Gents. I already have a banjo on the left side which I believe is standard so if I am going to do as recommended, what is the delivery point please. Having looked at the bike it seems that there needs to be oil dripped into that gap between the starter chain ratchet and the gearbox. Is that right?

You carry on with writing stuff Richard, by the way. It helps.

Thanks.

The oil feed to the gear is usually via one of the frame clamps/brackets which hold the gear in the frame. I thought that on the 1923 model  there was an oil pipe which ran parallel to the pipe which fed the plunger under the tank and which was simply operated by opening and closing the tap occasionally to permit the oil to flow (see the picture below from an example sold at Bonhams recently). I have this system on my 1925 Super Squirrel. However the Book of the Scott 1921 refers to a plunger which it suggests is operated every 20 -30 miles.

Anyhow, if you are to dispense with the feed/plunger all you really need is a separate tank and an oil pipe from that tank to the oil feed in the bracket with a conveniently- located tap.

I have found the oil tank in the second picture which might be of use to you – it is surplus to my needs. Let me know if you need it.

I have used Silkolene Comp 2 for quite a few years for my 2 Speeder Engine and happily use it for the 2 Speed Gear. Being fully synthetic it lubricates the 2 speed drums really well. I tend to pump the plunger quite hard every 30 miles to force the oil to the far side of the gear. I have a 40T low gear sprocket and have followed a slow car up the last part of Sunrising Hill on the Banbury Run slipping low gear without it grabbing. I could not do this with a non synthetic oil.
