WD-45 crank in a WD engine?

JiminIowa · Mar 5, 2010

Hi, do you think I can use a WD45 crank in my wd motor with using flat (WD) pistons? I heard that it may be too much compression. It will be used for work and not pulling. Any advice?

yes,if cranking pressure is to high add e85 to fuel to keep from detonating if your engine has a ring ridge in it rings will catch on ridge not recomended unless you have new sleaves , their are different wd pistons also wouldnt recomend tall pistons for farm use unless used high octane fuel alot of things need to be considered when swapping parts I have tall wd pistons in my pulling tractor with 4.5 crank has 225 psi cranking pressure to much for cheap gas but runs fine on e85

same size crank just did one not long ago but I did use new sleeves, rods, pistons and ofcourse bearings
good luck

it will work just finished putting my motor together monday night. But i am using it for a pulling tractor.The guys i talked to said that u will have more compression and more torque buy add 1/2 inch more stroke with the 45 crank.i do have a wd crank. i have a nice one that i took out of that motor it has been turned .20 under.If i knew this motor was a fresh rebuild i would of never tore it down.
