why flush a torque converter with kerosene? - PeachParts Mercedes-Benz Forum

As shown in the ATSG manual, there is a mercedes tool for holding the torque converter to move it back and forth while flushing it with kerosene. I've always been under the impression that if it has chips in it, it should be tossed and if it's good, well, why flush it?

is this on or off the car? and if it was on the car how would you get it in without contaminating the fluid?

I too think if its known to have chips that is reason enough to replace it.

this is off the car and considered enough of an issue for mercedes to have designed a "flushing mandrel". It's also stated that a torque converter with chips should be discarded - this is a procedure done to a "good" or keeper converter.

Odd, how do you know if everything is in fact out?

They say you do it 3 or 4 times and until the kerosene coming out is clear.

With the cost of a transmission (which failure thereof is obvious why its being flushed) would justify replacing the Converter too....its standard practice even though likely as they have no drains either on other makes.

I'm considering flushing the torque converter as a precaution for it being clean. The trans I'm going to rebuild has "failed" without throwing chips of any kind. I suspect the K1 clutch pack has excessive wear, but I won't know until I get it completely apart, and that's a couple of special tools away. If it's really clean, why do they suggest flushing it? Kind of goes against the "if it ain't broke, don't fix it" philosophy. Maybe flushing it removes very, very fine metallic residue - not chips. That's all I can think of.

What does these run?.....but I see your point if your tranny didn't grenade on you its worth a shot. Particularly if the FSM has a procedure for it.
