thanks AKSorry I missed this one Guy.
Taking off the water pump cover doesn't get to the gear cavity so you can't get shavings out that way. If you are careful and turn the motor up side down no shavings will get into the gear cavity.
The stock base gasket for late model 440's and most 600's is the .015" thick one P/N 5812494.
There are 3 other base gaskets available for these motors.
You can do a lot with your motors performance by changing base gaskets, but you have to know what you are doing as you decrease the squish.[/b]
It depends if your cases are within tolerance or not. The best thing to do is bring your bottom end to an engine tech or polaris shop and have them check it. Sometimes when the crank locks up, the bearing spins a little in the case and throws them out of tolerance. This can be fixed two ways, if it isn't that far out, the cases can be line bored to true up all the main bearing saddles. If the case is too screwed, you need to replace it. Most of the time the naked Eye can't tell if a case is good or not, so don't listen to your buddy who says "they look fine to me, throw a crank in it and go" because sometimes it works fine, and sometimes (like with my 900) the cases need to be line bored.okay Tom, question. I had a 04 440 motor that had the crank sieze at about 500 miles. my question is if i split the cases and do the mod are the cases still good, or are the junk along with the cranks?[/b]
I get the syringes from a local pet store. They are vetenary syringes. They come in several different sizes from 5ml to 25ml all with the same sized tip. That one is a 12ml. I inject about 5ml (cc's) every tank of gas.Hey Tom, where did you find a syringe with the amount marks on it that fits? Also, how much oil are you shooting in it, the recommended 10ccs by Polaris?[/b]
