bigboybanshee Posted April 28, 2005 Report Share Posted April 28, 2005 Doing a new top end on a friends Blaster, Kerosene good to use to flush bottom end out? 361570[/snapback] I've heard of people using kerosene but IMHO it's best to split the cases. You never know what might be wedged in a crevice that could pop out and fubar something in the bottom end Going through the bottom end shouldn't take but a few hours to tear down, clean, and re-assemble...

fixitrod Posted April 28, 2005 Report Share Posted April 28, 2005 You can try to flush but I wouldn't risk it. If there is in metal that made it into the crank seals they will go bad and ruin your new rebuild. A few of us have tried and ended up rebuilding again.

. Posted April 28, 2005 Report Share Posted April 28, 2005 there isnt much area in a blaster engine for stuff to hide.....I got a blaster that grenaded a piston pretty good, crank wouldnt turn over because it was wedged with a piece of the piston. Got it broken loose, got all the stuff I could out of it, flushed it out with some kerosene and threw it back together with a new top end. Thing got the shit beat out of it for over 2 years trying to keep up with a 250R, banshee, and a raptor. It finally wore out and I put another top end on it and sold it.

locogato11283 Posted April 28, 2005 Report Share Posted April 28, 2005 3500 psi pressure washer will take care of that Quote Link to comment Share on other sites More sharing options...
fixitrod Posted April 28, 2005 Report Share Posted April 28, 2005 I assumed it was a melt down or something. If you are just redoing the top end kerosene. I also missed the fast that it was a blaster... Quote Link to comment Share on other sites More sharing options...
sheefreak Posted April 28, 2005 Author Report Share Posted April 28, 2005 You could tell it was way lean, the exhaust side of the piston basically disintegrated until it reached the first ring landing and a chunk gave away and that was it. The pieces that were in the exhaust were so brittle that I thought I could get away w/flushing it, but if it has been in you fella's experience a bad idea not to split the cases, I guess I will go that route. Any more input? Quote Link to comment Share on other sites More sharing options...

Any more input? 361687[/snapback] i broke a reed in a motor and ended up using tranny oil ATF to flush all the shiz out, just fill the crank case, cranked it over everything stuck to the crank so i could get it out, then i just turned it upside down, and blew it out with a presure washer. no problems with it so far.

89Steeda Posted April 29, 2005 Report Share Posted April 29, 2005 I did the flip it upside down, then steam clean it, carefully a few times. Then I flipped it right side up, filled it to the top with diesel, worked the crank easily back and forth, dumped it out. Did this over and over about 4 times. This was on a CR 250, but its the same principle. Good luck, I'd split it if I had to do it again, my Warrior just got split tonight.

sheefreak Posted April 29, 2005 Author Report Share Posted April 29, 2005 Ended up splitting the cases last night. What a pain in the ass, vertically split cases. It took a while to get the crank bearing pressed back in the case, but we got it and crank is turning true and free. Makes a banshee motor look like the best design ever.

sheefreak Posted April 29, 2005 Author Report Share Posted April 29, 2005 It wasn't that hard, just a lot nicer to split a case on a banshee. Quote Link to comment Share on other sites More sharing options...
