Toffee and the Klaxon motor gearbox

[treefrog]

Trying to sort why a viewer that was running slowly, I had omitted to check inside the motor gearbox and discovered one of the worst hard grease toffee attacks I have had. … I should have checked this in the first place, but I am going to ask an obvious question as I'm less familiar with the larger motor and gearboxes. A these reservoirs filled with oil given there is a an oil filler at the top or is grease used? I assume oil, which means the seals need to be good and tight. Most smaller gearboxes tend to be light oil and a little grease, but not like this…

I'm also no expert but I do know that gearbox grease was/is the norm for this sort of gearbox, but as I remember it it was injected in through a nipple, so, in this case, I don't know if the oil cap and oil filter makes a difference and it should be oil, but it seems unlikely. Gearbox grease is, of course, still a common product available in many different makes on Amazon/eBay etc.

Yes the oil well I thought was just to fill chamber up, but now think it is an oil feeder as is separate from the main gear section and had a wick inside. I suspect it acts like an oiler you get on motorcycles to lubricate chains…..I have greased gears and topped up tank, hopefully someone will correct me if wrong

Treefog ...

I think you're on the right track with the wick/oil feeder scenario.
The weak point in oil alone is not only the gaskets and seals, but also the shafts protruding from the sides as the bearings they sit in may leak. If it were mine I'd introduce a good dollop of quality grease, that you don't want moving parts to cut channels through. A really superb product which has been around for nearly 60 years is "Bostik Never Seez Regular".
The Pros: -
Being a Bostik product it's easy to find on the web.
It just doesn't seem to dry out and doesn't go hard.
Although they put a best before date on it, I'm currently using a jar I bought in 1985 and it was 15 years old then.
It contains very fine flakes of nickel, graphite, and other additives known to enhance anti-seize performance and is semi fluid.

The Cons: -
Cheap it is Not! I have a running search for it on eBay, and if reduced enough I always buy it.
Because it doesn't dry out, it easily transfers to your fingers .. then door handles .. light switches .. your nose. Leading to divorce. Even years later.

For 40 years I've been using it on Slots, Marine Diesel engines, Car engines, Steam locomotive valve chests. But never on Harleys, they are more than capable of unscheduled self disassembly at any speed while out on the road, without any assistance.
Add some mineral oil to the grease to help it stay on the cogs.
As for the wick/oiler it'd be great to add a small oiler reservoir like stationary engines use.

Again use grease and oil mixture.
