    Some way, some how, I lost that spring (16). Can I pick this up at a local hardware store?

    I have purchased a spare spring but the other one is missing also so I am short one.

    Also, after looking over the machines I noticed that the paddle wheel, on one of the machines, is missing. Any advice on where I could find one?

    By the way I love this site and the info.

    Thanks,

    Welcome to the Hulk Matt

    Parts sources can be found through my signature links below.

    Polaris part # 7041995 SPRING-COMPRESSION is about $10
    I am sure you can find something similar locally, but make sure it will not rust. I might have a spare spring around here somewhere

    Those springs do tend to fly out and go hide if you are not careful when taking the reverse mechanism apart. It might be somewhere in the bottom of your hull. Look/feel under the engine and among all those hoses. Also look around the rear where the jet pump tunnel is. Lots of hiding places for a little spring

    The 2410344 ASM-PADDLE,WHEEL speedometer sensor may not be available new. Call a few of the listed suppliers.

    The paddle wheel from a Yamaha or Seadoo will fit. Do you need the whole assembly or just the wheel?

    Thanks guys. I'll check with my local hardware store for the spring. Now that I think about it I'm not sure that I didn't lose the washer that holds the metal bracket. I'm sure that would be a standard stainless washer correct? I sure hope these machines work! Got them from a guy I know and he needed the $.

    Beerdart, I just need the paddle wheel and pin.

    Yamaha or Sea-Doo part numbers for the paddle wheel?

    Actually, do you know if the whole Polaris speed sensor assembly will interchange with a Yamaha or Sea-Doo part, other than the connector/cable into the hull?

    Do check the basics before you go riding.

    Compression, fuel pressure, correct spark plugs, etc. Also check for loose hose clamps, nuts, bolts, and so on. Check everything you can.

    Click my signature links and prepare for some reading

    I will try and check as much as I can. Thanks K447. I use to live in Mississauga when I was younger. Looks like one of my msx's is the same as the one in your picture.

    Mine is a 2004 model. Check your HIN number for the model year - last two digits.

    The mounting is different for the three Seadoo also incorporates Lake Temp in the sender.

    Yamaha # for the wheel only. GJ1-U835D-00-00 .SERVIS KIT (SPEED SENSOR) $25.31

    Seadoo does not sell the wheel separate.

    Matt I have 2 Virage i's.... new member as well. These guys are awesome. I was doing the same "fix" on mine and I made sure I kept an eye on that spring.... still went for a ride. Just stuck a magnet under the fuel tank and hit gold. I found it to be much much easier with the oil tank removed.

    I am far from an expert on this but after taking mine apart twice and seeing how there is no margin for error, binding, mis adjustment I would want to put a factory spring in there. I suspect those cams are machined and calibated based on many factors one of those being the tension and size of that spring.

    Per the attached photos, you do not need to remove the entire mechanism from the hull to fix it.


    Pry the plastic cap (1) from the outside of the reverse handle (33). Use a 10mm driver to unscrew the long bolt (2) inside the hollow handle. Remove the handle.

    Under the hood, remove the cotter pin (25) and washer (18 ) connecting the reverse arm (26) to the reverse cable (34). Slide the cable out of the hole on the reverse arm.
    Note: This step is not entirely necessary, but it is how I got mine apart.

    Remove the Philips head screw (19) holding the Reverse Lock (17).

    Remove the 10mm bolt (15) holding the metal bracket to the center of the large reverse arm. Don't lose the washer underneath (14).

    Note: There is a captive nut on the back side (13).
    Don't push too hard on the bolt while unscrewing it, or the nut will push out into the hull and go hide somewhere.

    Gently bend the metal bracket (20) away from the reverse arm, enough to allow the reverse lock (17) to be removed.

    Alternate method; If you don't want to bend the metal arm, remove the hidden 10mm nut from the rear support stud (30). This will allow the metal bracket to be removed. Don't drop the nut or washer

    Slide the plastic reverse lock pawl (17) and spring out from under the metal bracket (20). Don't lose the spring (16) that is inside.

    Now you can use the 10mm driver to gently tap on the end of the cam shaft (12). Mine was quite snug. Tap the cam shaft all the way through. The pinion (9) will come with it.

    In my case, the problem was that the nylon plastic cam shaft diameter seems to have expanded (or the pinion gear hole shrank), enough that the pinion no longer freely rotates on the cam shaft.

    This causes the reverse gear arm to remain locked when you try to move the lever, and it feels like it has jammed. Fight with it enough, and the lock suddenly releases and works, or you break things

    I had to use a hammer and drift to tap the pinion off the cam shaft, and it was tight all the way. Time to do some fine sanding...

    Apply sandpaper to the shaft until the pinion slides smoothly on and off the shaft. Also make sure the shaft now slides freely into the hole where it goes when re-assembled.

    The pinion (9) needs to freely rotate on the cam shaft (12) (next two photos).

    Apply waterproof grease to all contacting and sliding parts, shafts and gear teeth as you reassemble.

    I see that Babbitts shows the cam shaft part# 5433955 being SUBSTITUTED BY 2202170 ($18US), also the pinion part# 5434067 also SUBSTITUTED BY 2202170
    Sounds like an updated version, perhaps because of the binding shaft issue

    This video shows the pinion and cam action, without the locking pawl present.
    Note the motion of the cam before the pins move the pinon gear.


    Here you can see the reverse sensing switch and Forward/Neutral/Reverse detent pin


    When it is working properly, the reverse mechanism looks like this.
    Note how the cam motion releases the locking pawl before the four pins start moving the actual gear. This is how the system allows the operator to move the reverse bucket usign the handle, but jet pump force cannot move the bucket if the locking pawl is in position.


    And finally, mounted in the hull.
    All moving parts have been greased.
    It really is about a two finger amount of force to move the reverse lever when everything is working properly.




    Great info here same thing with my 2002 Virage i. In addition mine also has I nice little bend in the reverse cable right by the gate. Even with the cable bent there is no binding because the bend does not extend into the telescoping part of the cable. I am certian that it is throwing off the adjustment.

    Took apart the gear mechanism because it was binding as well. Found #12 was stuck and binding inside #8 the housing needed a drift to work it out some sanding and marine lube it was good to go. Got it all back together and once assembled it would move freely until it got to Forward and the cam#9 would not release once locked in. If you moved it around eventually it would come loose.

    Took it apart again and this time I removed the whole housing so I could get my head around the way this mechanism worked. Also found that #9 was siezed on #12 and just that binding would cause the whole operation to fail. Honed #9 and some sanding and marine lube on that as well. Now it works on with minimal effort.

    As K447 previous posts on this I am dying to know if #12 expanded or #9 shrank.

    Also removed the reverse cable and straightened it. 1 Before pic and 2 after pics

    $20.00 worth of marine lube (with plenty of left over)
    $13.00 worth of 3M 5200 series thru hull sealant
    Should be like new

    Nice writeup but I still can't seem to find how to actually operate my Lever. Push, pull, need advice in order to troubleshoot.
