Oil & Grease - Old Dave - 24-02-2025
Oil
I have a pair of new oilite bushes for my Girling brake cams. I guess engine oil is best, but how long do I need to soak them before pressing in to the housing??
Grease
I am fitting new felt seals in the front hubs. Do I need to soak them in anything? OR is a smear of grease on the inside enough? (as recommended by Doug Woodrow in the Big Red Book)
Thanks in advance for any guidance.

Oilite comes ready loaded with oil, they say. I always soak them an hour or two in hot oil. The stuff that goes in engines. I use lip seals not felt on the hubs, but if I did use felt it would be with a smear of grease.

The accepted period lubricant for felt seals was tallow, a form of beef dripping made from rendered suet. I have done mine in duck fat, which does the job. Just heat it up until it melts and leave it in the dish overnight. I guess common or garden grease will do fine, some of that stuff you have a 3lb tub of, but wipe off the excess.
The secret for your hubs is not to over-lubricate. Too much and it'll go where you don't want it.
I just use the duck fat because we often have "confit de canard" for tea, and I always ask the Mem'Sahib to save the fat. It's great for roast tatties too.

Alan,
Thanks - I wondered if that was why they were called oilite!!
I have some lip seals but they are too big to go in without damage - it's not a lot but too much - SO! new felt it is.Bruce
Thanks for that - you have made feel hungry now. Yes I suppose the PH stuff would suffice and the house management is clean out of tallow.

Well changed my mind and ground a little off the outer edge of the lip seals and managed to press them in. I found that the outer-part of a 1970's Maxi front wheel bearing is just the right size for pressing in the vice. So the felt will go in the spares box.
QUESTION -
The Girling brake levers have a small felt seal/washer between the lever and the oilite bush - does this mean it should be oiled?
