Old machinery, oil requirements
Hi all,
I got a mate that has a bakery and they have some old mixers in it. He asked me the other day if he knew what the numbers 357 meant which are stamped
on the oil fill cap, and what type of oil he should be using.
Does anyone have any ideas what 357 could refer to in an oil ?
It's a gear box and bevel gear filler port, but my guess is that the machine is from the 40's maybe earlier.
What sort of oil would people use in a gear box? Obviously food grade, I see there's a 320 gear oil which has its name based on the viscosity.
Could the 357 be related to that?
Any help appreciated.
I can get more details if needed.

If you find out the name of the machinery maker and if they're still around they may be able to advise.
Failing that you could try a company that supplies oil for that type of machine advice.

If its from the 40s I'd ignore any oil grades they recommend, god knows what horrors would have been in it, made from lead or puppies no doubt.
I'd look up a similar modern machine and use the same as they use. I'd be worried the oil seals, assuming they even fitted them were
perished. Anything leaking out into food would be a big no no. I'd also get the electrics checked out or replaced before it kills someone.
Sounds terrifying tbh I'd only touch it with a big stick.

Modern motor oils have a detergent in which can damage some components such as phosphor bronze bearings, so another factor to consider in addition to
oil type.
Might not be important here if it's a gear oil, but my Grey Fergie (1950) uses the same oil in the engine and gearbox which doubles as
hydraulic oil with a pump in the transmission.
You can buy classic oils without detergent.
Just something else to consider.
Maybe give these guys a call?

Peugeot (and others probably) certainly used to have engines and transmissions which shared the same oil. I'd guess it was quite a volume of
oil to change at service time. I guess the benefit is regular transmissions oil changes, but then I've never bothered changing tin top
transmisson oil in vehicles I've owned. I read DSG transmissions are reliant on oil services to keep them functioning correctly, but have never
had one so it's not been a consideration for me.

I work in the food industry and going on experience with similiar machinery a 220 grade food lube would be ok, have a look for Rocol foodlube 220 gear
oil or similiar.It is difficult to know what the orginal spec would have been but a modern oil would exceed the original spec and suspect it will
just be a basic spur type gearbox .
