i have an 88 model dt85.the bottom cylinder rod bearing got hot and seized up.i found a good deal on a used crank on the web .the cranks seem identical except the seals between the cylinders.the ones on the crank beside the main bearing are the seals i am refering to.mine has a plastic or hard rubber coating on the entire seal with a ridge on one half the circumference.the used one has an aluminum seal with a groove and an o-ring.they are the same size but a different style.just wondering if anyone knew if they would interchange.i don't know what yr. the other crank is.thanks
