I’ve been thinking about how to flush my 3H. As most of us know already, the old manuals suggest flushing it out with kerosine. That’s frowned upon now as being too risky. I agree with that. It’s one thing to flush it with K1 in a huge, open, war factory, where guys with fire extinguishers could take care of things safely were things to go south. It’s another thing for that to happen in my garage.
Lubricant suppliers now offer specialty flushing oils to use. These are probably pricey, and might me difficult for me to obtain. What I am thinking of using, instead, is inexpensive, detergent, automotive, motor oil.
We are warned not to use it as the normal lubricant in these machines. I think that’s because the detergents in the oil keep the dirt in suspension. That dirt is removed in modern cars by way of their high tech oil filters. My 3H doesn’t have one of those. Instead, it depends upon the dirt dropping out of suspension into a sump. The sump is drained out during flushing. So, detergent oil shouldn’t be used normally.
When flushing, however, the idea is to get as much residual dirt as possible into suspension in the flushing medium (the kerosine) then drain that medium away, along with the suspended dirt. Sounds like detergent oil would be an excellent flushing medium.
Does anybody out there have any counter considerations?
