cleaning autolube pump
Kayto wrote: I'm not going to say that this is the absolutely best way to clean the pump, but when I cleaned the one for my '74 DT250, I removed it from the case, but did not disassemble it. I then immersed it in WD40 and turned the wheel on the pump. This circulated the fluid through it, and I could see that it was pumping out the outlet port. I finished it by immediately adding some 2-stroke oil into the pump and working it through, again by spinning the priming wheel. Having the pump off made it easer to check the end clearance for the stroke shaft also.
Good idea I have 1 to clean out for my friends DT175MX shortly.
usually there are sludge deposits inside the main pump body .
I'm not sure you'd really clean those with just soaking .
They are pretty fiddly to work on . After I got frustrated with mine ,
I sent it off to DEET who successfully overhauled it , for a very
reasonable cost .
