Never seen one before, but that looks like one tank of a sled.Well, this didn't happen today, but last weekend I finally fixed a long-standing problem with my Skandic 900 ACE. It would occasionally rev up without me touching the throttle. This happened both at idle and while riding. And when this happened the speedo would go crazy, like reading 112 mph while sitting still, and then coming right back down to zero. And at high speed or load the speedo would start bouncing up and down and the engine would bog down, as if the ECM was trying to adjust mixture based on speed. Over the course of a year the problem got progressively worse, none of my buddies had helpful advice, none of the local shops had experienced the problem, and my casual troubleshooting didn't help matters. Frankly the only people who believed me when I described the problems were the ones who had stood next to my idling machine and observed the speedo when it acted up - which it didn't always do.
Finally I got serious and tracked the issue down to the speed sensor, which is located in the gearbox cover. Of course Skidoo won't sell you the speed sensor by itself - much to my disbelief I had to order a whole new gearbox cover for $200.
Here's the new cover next to the old one.
Here's the outside of the two covers. The speed sensor is glued into a channel, then covered with an aluminum strip. On the old cover, you can see a dent right where the punch is pointing. I believe the wiring was probably damaged there; I've no idea how that dent got there.
The inside of the gear case - you can see the four little magnets on the drive shaft that actuate the speed sensor in the cover.
The only tricky part was removing the shift fork from the old cover and transferring it to the new cover. Two roll pins hold the fork onto the shaft that passes through the cover:
Getting the fork out was easy enough, but I needed four hands to install it in the new cover; one to hold the shift fork steady, one to hold the roll pin in place, one to hold the punch, and one for the hammer. Despite my best efforts I couldn't get a pin started. It didn't help that I don't have any starter punches, and my pin punch wasn't quite the right size.
Finally I had a little inspiration: I carefully taped the roll pin onto the punch. That made it a three-handed job and after a few tries I was able to coax my left hand into doing two of those jobs at once.
Off to the woods for a test run, and to replenish the cabin with firewood. Such a relief to have everything working right again!
Oh, and I'm looking for ideas on what to do with the old cover. Best idea so far is to turn it into a lamp.
I'll be over in about... uh, three days? Reckon you can keep some warm for me?
We already ate them all. Plus the German potato salad, cole slaw, tomato cucumber salad, and Tres leches cake.
How about pulling the old speed sensor out and repairing it? That way when you run over your next stick or whatever, you'll have your replacement ready.Well, this didn't happen today, but last weekend I finally fixed a long-standing problem with my Skandic 900 ACE.

Well shoot! Now you tell me! I'm an hour from Boise right now....
Don't get me started...
That looks like a nice project. If you're getting rid of one that nice I'd like to see the ones that made the cut. What was your criteria for getting rid of this one?
Got this ready to go on the rollback at the "beginning " of the week according to the tow truck driver, maybe now I'll actually be able to clean up my garage taking the total amount of vehicle projects down to 3 wooohoooo
It's a buddy of mines I just put a new wiring harness in it, 3d printing a gauge pod for a iPad mini, built a main wiring panel (so he can't hook up the battery backwards again). The other projects consist of a twin turbo xtreme blazer, a streetable Dakota, and a 01 ram lol
Just how many of those Scotchlok things are nestled in that mess?I got the power windows of the Brick working again! I took everything apart and tested everything and determined there was nothing wrong. Put it back together and tried the windows: Nope. Took everything apart again, re-tested: still nothing wrong. Try the windows again...
THEY WORK!
I hate power windows.
Now I have to stuff all this ****
back into the tiny space where it lives.
Thanks Outlaw. Have a couple of ideas and there are some washers on line that look suitable. Needs to be 3/16" ish or 4 - 5mm thickness.
A metric **** ton. I'm not even sure what the hell they're for. They don't appear to be splices, but the wires in them are stripped. They micht be for test points? Looks like they'd take a male spade lug.
Battery tenders are cheaper than batteries.Waxed my new (to me) work sedan, washed and gassed up my wife's SUV monstrosity, and started/jumped a few vehicles in another storage site prior to moving them to my newly completed room. The "Car Salon" (as I have been amusingly referring to it over the last few years). I can finally starting to fill it with my modest collection of junkers. Now on to the front and final portion of the remodel.
I got the idea from The Samba Vanagon forum.
