Dear Ralph:
I have a 1993 Polaris XLT. My problem is the water pump was leaking, so I removed it to check it out. The main seal was bad, so I called my Polaris dealer and he told me the only fix was to replace the entire pump assembly for about $300. Do you know where I can get the seal for this pump?

Many of the water pumps on snowmobilers are like this; if the seal goes bad you replace the entire pump. This is pretty common with many older sleds. In the case of the XLT, I believe the pulley is press fit onto the shaft and there really isn’t a viable service method for replacement of the seal. Many times you’ll find things like water pumps, oil pumps and even some fuel pumps where the unit is sold as an assembly and individual replacement parts are not available.
Many times the pump assembly is supplied by another vendor to the engine manufacturer. Other times the assembly of the pump is such that disassembly and reassembly will not meet certain specifications or tolerances. Think of it like a circuit board in your television; the problem may be a fifty-cent chip, but you’ll have to pay hundreds of dollars to replace the entire circuit board.

    Dear Ralph,

    I bought a 1987 Yamaha Phaser for my son to learn on in the yard. It starts and runs fine until the engine warms. The engine heats up and sounds as though it is flooding or the choke is engaged then stalls. I changed the spark plug, check gas & oil then start the engine. It runs ok until it heats up then stalls. It misfired last season as well. It has 2,700 miles on it and I am not sure if this could be a bad ignition coil or other problem. Please advise.

    Thank you

    DEAR RALPH-I AM IN THE SLED BUISINESS AND HAVE BEEN GETTING QUITE A FEW SHOCKS TO SERVICE/REBUILD LATELY.I GOT EXPERIENCE WORKING ON SHOCKS WHEN I OVAL RACED A CAT IN THE EARLY 90’S AND STILL HAVE THE CAT PERFORMANCE MANUALS WITH THE SHOCK SPECS AND DETAILED INFORMATION IN THEM. THE PROBLEMS I ENCOUNTER IS OBTAINING IFP DEPTHS,NITROGEN PSI AND SERVICE INFO FOR THE OTHER 3 BRANDS. SOME DEALERS MECHANICS CLAIM THAT THEY DON’T HAVE THE SPECS AVALIABLE OR THAT THE SHOCKS ARE NOT SERVICEABLE. I KNOW THAT THERE ARE QUITE A FEW PLACES THAT DO THE HPG’S, OHLIN’S, RYDE FX’S, WALKER EVAN’S, ECT. I HAVE ALSO FOUND IT VERY HARD TO GET SPECS ON POLARIS SLEDS EQUIPED WITH M-10’S AND FOX SHOCKS. ANY HELP WHERE I CAN FIND THIS INFO?-THANKS, DALE
