Whats the trick to getting the jug down over the rings. Its been a battle all night.
Let me start from the beginning. Got a buddy with a '05 foreman 500 that has gotten water in it a few times. Its all his fault, he is a big boy and when it goes under and stops breathin, he isn't the fastest to get off of it and get the exhaust out of the water.
Weekend before last, his ride started smokin and so we pulled it apart, and he purchased a new piston, rings, and gaskets. The piston looked fine, the only reason we replaced it was the because of the wear between the pin and the rod. We took the jug to the machine shop and had it honed. We attempted to put it back together and run into some interference while tryin to slide the jug on. We easily got the top two rings into the jug, but battled the oil ring. After about the 7th attempts and probably some excessive force, we found that we had damaged the lower oil ring. No problem, we decided to yank one off the old piston and let her go. Bingo. Slid right on. We rode the last weekend and half way through the ride it started smokin again. I know he didnt rawhide it, so i was clueless at this point. We tore it back down tonight and found that apparently when we put it together the first time we either broke or damaged the ring landing for the oil ring. A piece of it was broke off above the piston pin. Im assuming that we damaged it upon the installation and it broke off during the ride. We decided that because there were no signs of excessive wear on the old piston, we would throw it back in with another set of new rings and the pin from the new piston and let her rip. But, we are incountering the same problem again. It slides past the two compression rings with relative ease, but when the jug meets the oil ring it becomes a battle.
Whats the trick? Do we need some sort of ring compressor. I have put together 250X's, 300EX's, and 350X's and have never met this much resistance and have never used a spring compressor. From the ones that I have seen, I'm not sure how you would get the compressor out after the rings went in anyway.
Help me out.
Thanks,
Charlie
