    Are you getting the storm

    Global warming just makes the snow not stay long enough to make trails. We still get lots.

    I would have liked to see the crankcase split in half.

    The main bearings are lubed by the oil pump oil directly. I don't think that is the problem. Due to the two piece forged crank assy. pressed together in the center, there is no way to assemble the rods on the crank pins. So the rods have a bolt on cap like a 4-stroke BUT with needle bearings in there. That is what exploded in the early engines cutting the crankcase in half. Maybe Motorhead can elaborate on his engine failure instead of "my engine blew up". Like you said, inquiring minds want to know. Doo problems seem to hushed up. Lay it bare !

    Hey, don't shoot the messenger. I am only pointing out what is wrong AND how to fix it. I own one of these chain cases as does my son. Therefore I fix them both. It is definitely a weak part of the sled, but if serviced yearly with a $3 bushing, a tension adjustment, and an oil change, it will stay together. Not sure if it will at sustained 200Km/hr like some want to do, but for this old guy it does. I have had my share of 2-stroke engines cold seize, piston melt, loose rod, broken stator, cracked flywheel, etc, etc, etc. I know how to fix them.

    Make sure you get a backward running 2-stroke. That way there is only a chain a two fixed mounted sprockets. What could go wrong ? Then you will only have to keep the engine together.

    If you look close on the top picture in my last post, the right side case is off the engine. This was to see how things work inside and understand how and why the starter idler gear and the starter shaft teeth have been breaking. I figured that out too. Note that the design of the magneto is backwards to old 2-stroke engines. The flywheel is mounted backwards and the stator is mounted to the case. I never had a starter gear failure to this day because I always held the key until running. I also got the ECM re-flashed twice on my 15 7000 until they got it right and now it runs like a Cat-ilac. If I have a problem or hear of a problem, I investigate instead of just bitching and complaining. This investigation cost me $16 for an engine case gasket.

    There will be no changes made until the next chassis is made, if that ever happens. I can only assume that it will be worse based on the kids designing with Solid Dick using FEA to test things out. They obviously have never fixed a sled, and maybe never rode one either. The old boys have been forced to retire so there are no wise ones watching anymore. So I have taken on the task to re-engineer the thing to make it reliable. 1700Km this year and it drove out of Quebec on it's own power. Currently apart in the garage waiting on bushings from McMaster-Carr. May be waiting a long time.

    The top chain sprocket has the bushing inside it and it rides on the inside of the top jackshaft. The right side of this gear has small pointed teeth on it just like in a manual transmission. To the right of this is the sliding shift collar and reverse gear, splined to the jackshaft. The shift fork on this sliding gear holds the collar against the top sprocket driving it forward. So the top sprocket and the jackshaft are now turning together, so there is no relative movement of shaft to sprocket. So the bushing does not wear by turning, but by the harmonics of the chain and sprocket. The gear change shifting motor is a 2005 Saturn passenger side power window motor. It turns a pinion which moves a rack that shifts the fork. The worm wheel in the motor is plastic and strips just like the garage door opener does. This is also a problem because it is too hard today for anyone to run a shift lever. When the top sprocket bushing is worn, as mine is right now, the sprocket is running at an angle which pushes the shift collar away and damages the shift fork. Then it is stuck in reverse. Mine has not gotten to this point because I did a yearly inspection and found it in time before the shift fork got damaged. So the whole design is a POS. The 199x to 2004 design was bullet proof and had the three spring loaded pins to engage the bottom drive gear. That would not work now since riders right hands are not up to the task of pulling out the shift lever and pushing it back in. The magnets on the bottom shaft are the speedo signal. The pickup is in the outer case. The bottom picture shows the shift collar/reverse gear and fork removed. You can see the engagement teeth on the outside of the top sprocket. You can also see the flat head screws on the tensioner bracket. TIG weld the screw head to the bracket on each side so the screws cannot come loose. Both bottom sprockets are splined to the output shaft and rotate together. In reverse, the top sprocket turns backwards on the jackshaft, and that is why there is a bushing in there. It is not hard enough.

    The biggest problem is the two flat head screws holding the axle for the chain tensioner wheel come loose and the the axle spins and the screws fall out. The wheel then falls to the bottom of the case where the bottom gear blows the tensioner wheel through the case and breaks both halves. The case does not magically break from the immense hp going through it. The permanent fix is to TIG weld the screw heads to the tensioner bracket so they cannot come loose. Problem two is the teflon coated oilite bushing in the top sprocket. The pounding of the chain going over the sprocket flattens out the inside half of the bushing making a taper, and the sprocket wobbles. This makes the chain loose as well as forcing the shift collar to jump out of gear, wrecking the pads on the shift fork. The sled is now locked in reverse. The solution here is to press out the bushing in the sprocket and replace with a leaded bronze SAE 660 bushing or better yet an aluminum/bronze bushing. The bushing is 1" ID, 1.125" OD x 1" long. Once pressed in the gear, cut to length flush with the gear and de-burr. I hope this has cleared up any misconceptions with the chain case. Anyone that opens it up once a year to change the fluid can easily address this and ride with piece of mind.

    GMRS is limited to 2 watts in Canada. Power does not make that much difference with the UHF frequencies used when in hilly terrain. It's line of sight communication.

    Gps is receive only. So somehow the coordinates of each sled must be transmitted to each other sled. This would not be far without cell towers. The Garmin Rhino did this by Gmrs. I doubt the signal would be reliable more than a km based on how my so called 65 km range Gmrs radios worked.

    I don't think the radio range would be very far in hilly terrain. Unless each sled in the 5 mile chain is a repeater.

    Canada produces enough milk for the country. We produce enough beef and pork to export where ever possible. Lots of corn, wheat, canola, oats, barley. Fruit and vegetables are a problem in the winter. Manufactured goods are a big problem since we have been forced to buy everything form abroad. However, that could/would change if the need was there. Price would be more expensive though.
