HI.
Found antifreeze instead of oil in my just bought , 1995 Polaris Explorer 4X4 400, balancer case.
Have to replace oil seals and gasket of the fuel pump.
Removed yesterday the pull-start case. Going to remove the flywheel.
In order to remove the right third of the engine case, to expose the water pump, should I remove the entire engine from the chassis, or I can do it with engine in the chassis?

Sorry about the "fuel pump" in the subject field, I'm talking about the water pump.

 

We all make mistakes at that time of the morning.

I have repaired water pumps on the 400's in the frame, as well as pulling the engine - As long as you don't have to work on the balance shaft (ie replace the inner balance shaft bearing ), the water pump is less time consuming to do with the engine in the frame.

You need to at least replace the (2) water pump seals and the water pump bearing, but make sure you check out the balance shaft for "slop" before you start putting it back together - it could be the cause of your water pump seal failure. If you have to go into the balance shaft, it is much easier to do with the engine out of the frame where you can get to everything. Also, if you were pumping water through the exhaust - I would recommend replacing the crankshaft bearings and seals.

You can find the parts breakdown to get a good idea of what you are looking at here:

You can get a complete K&S oil seal kit (ALL the engine seals including the WP seals) in the neighborhood of $22 from your local Armor Tech dealer (www.armor-tech.com for the dealer locator) as well as crankshaft bearings, otherwise all the gaskets, bearings, and seals related to the WP and balance shaft repair are only available through Polaris - at Polaris prices.

 

For me, on the other side of the ocean, it was 11:00 AM, so the time is no excuse for the mistake.

10X again.
