Hello All ; I am reading and enjoying your Website and was considering building my own version of ATV . It is interesting to view all the opinions of people actualy using these specially built vehicles . #1 Would a auto-type
differential be the best choice for spliting power to each side ?.#2 How about using commercially available cone clutches ? #3 Has anyone ever built their own reversing epicyclic geartrain ( planetary gears w/ forward & reverse two brake bands per side )#4 Wheeled vehicle or track laying ? #5 Or hydraulic drive as in your forum already opened? Lets kick this around as there looks like a number people interested. |

Alex,
1. Possibly but an old t-20 would be better.
2. Cone clutches might work.
3. I doubt it unless they spent a lot of time.
4. Depends on what you want to do.
5. Hydraulic drive eats too much power with a 20 hp the best speed you would get is maybe 15-18 mph at full throttle. |

Alex,
Toward the bottom of the restoration photo section ( http://www.route6x6.com/photogallery/restorationphotos.html )of this site, a guy named Mark Murrany put a reverse gear in his Terra tiger using parts from an old GM transmision. From the photos, it looks like he did an excellent job. I tried to find his Email address to ask some questions about how he did it as I have a Tiger also, but I couldn't find him. Anyway he used gears for the reverse and cone clutches to split the drive. Just wish I could get a hold of a genius like that.

Just checked out the photo of Mark Murrany's setup in his Tiger. WOW. Would love more info on the cone clutches!!!!! |

Thanks for the reply guys , I see there is some interest here. I would guess that Mark used the gears out of that trans ,although he must have some form of gearbox around it to contain the oil.
Anyone who wants to look at cone clutches and other drives open www.hoffcocomet.com/comet.com and open up
drive components . |

I too would enjoy takling with Mark Murrany about his design. I think that a number of older units could benefit from it. The Scrambler is one such unit as well as Attex with the ATV5000 transmission and I am sure their others...SO MArk if your out there please tell us more!!!!!! |

Guys,
Thankyou very much for your comments on my tiger.
It was as you say a labor of love because I had to machine everything from scratch. As far as the clutches go there are marginal for even a 18 h.p. motor. They are the same size as the originals. That is where I made a mistake. I eventually did a horsepower calculation on it and found that they where too small. You can increase the spring pressure (some) but then your steering effort goes up. If we all stuck with the original flotation tires instead of large cleated tires it wouldn't be to bad. Newer style tires and rims suck up more poneys when turning. Till later

So Mark, did you make drawings or sketches that you might like to share? I do a fair amount of machining and would enjoy to see more! Please feel free to contact me Gary in VT (gharper@pcilightingcontrols.com) |

I have some parts drawn on my computer that's got a CAD program. I have no way of extracting those files as to get some prints though. I recently got laid off from my job and that's where I could plot my files as I do not have a plotter at home (yet). I also repowered my Tiger since those pictures were taken with a 23h.p. briggs vanguard. The single cylinder 2 stroke just didn't have quite enough power for Humphrey's steep hills. After the repower I took it back to Humphrey in october and it worked just fine. The tigers are unique and rugged. It's nice to hear from others who find them fun.

I can plot then and convert them to other fromats if you would like. So let me know as I said I am intrested. There has been a lot of intrest in the past to add a true reverse to the Scramblers and I think you may have a design that would do it. |

Hey guys,
Let me jump in on this. Mark, I would sure like to see your cad drawings. Electronic files are fine for me too, most any format. I added a reverse to my tiger last fall using belts and pulleys. It works ok but has some serious limitations. I blew one of the clutches this winter and need to rip it apart and fix it (too cold lately). Maybe mine is overpowered for the clutches, it has a Polaris 340 in it my guess is maybe 25 - 30 horsepower? What do you think? Too much? Mark, again I would sure appreciate seeing your cad drawings!!

Guys,
I managed to stay underground on this board for over a year now but I guess I'm out of the closet now.You guy's and your enthusiasm is just too enticing not to say anything.Sheldon, years ago I thought to approach reverse probably much like you did. I would be interested in seeing what you have. As far as power goes my motto is, I'll take every pony I can get and then some. My next Tiger I want to put 3 cyl. Geo motor in only in the rear. It will be tight fit but I think it can be done.

A good way to share CAD files is to convert them to Adobe .pdf files. They can be viewed using Adobe Reader and you can zoom or pan and print them on your printer. I am currently creating AutoCad drawings of some Sierra Trail Boss parts and will be using the .pdf format to post them on my website. Any questions? Just ask. |

Maybe if we ask Richard real nice he will set up a area that cad files could be held for all of us to view and enjoy! |

Pete ; You said that an old T20 would be better to start with , how many do you need ? Where would you find these things ? are they very costly in used condition ?
I also noticed several people stating that tires with aggressive tread use more power , this forced them to go to a larger engine .I have 8 ATV 22X10X10 tires that are takeoffs and I have several small automobiles with small four cylinder engines 1.6 liter ( 70 hp at sea level ) and 2.0 liter ( 100 hp at sea level ) only half that Horse power at my 7200 ft. elevation , would they work ? I would have to machine an adapter to fit one of those centrifugal clutches to them . I would like to build a little larger model than the average ATV. Something almost the size of the Studebaker Weasel . Whats your opinions ? |

Al,
Yes a t20 would be good and you only need one. You can find used t-20's on here I'm sure somebody would be willing to sell you one. However, they are not rated for those larger engines if that is what your going to use for a powerplant then you might have to construct a bigger transmission out of a car rear end or something like that. |

There is a guy in New York running a Mitsubishi 4 cyl. engine in a MAX IV with a stock T-20. This engine produces 80hp. He has never had a tranny problem. However, his machine does enjoy a steady appetite of drive belts. Non-the-less it is a neat machine. |

hey bob: when hi torque/hi h.p. engine used on belt driven-torque converters, krevlar's variable speed belt MUST be used.......at least GATES produce it......bottom line is that kevlar's belt bounce stronger!!!!! |

Al....... I too have read this board for over a year (since I bought my Hustler AATV) without posting but the build your own does interest me. I have seen several 6x6 home built machine, but none are AATV.
On your weasel type machine, are you going to try to stay AATV or just land use??
I just sold a weasel, it was a very simple machine. Was a stock Studebaker engine, 3speed, and rear-end with sealed axles and gears vs. wheels. Had the two stick brake drive. I didn’t want to fight trying to find old Studebaker parts to keep it running so sold it for twice what I paid for it. |

Has anyone out there ever tried using syncronous belts and sprockets instead of chains. I am thinking of trying this on my Trail Boss. The main issue for starters is clearance, but if that works out, it would be a matter of durability. Gates Polychain GT II looks like the ticket. Image no chain lube gooping up the inside of your machine! |

MIKE ; I think that for the type terain which is here Land use ,will be the one for me. I have found the little Studebaker engine to be very underpowered at my elevation of 7200 ft . The best I can do is 15 mph , just not enough oxygen , probably needs to be supercharged to perform properly . |
