I just purchased a McKees Bros. Roughrider.I was told there was a 399 Yamaha snowmobile motor in it at one time.I want to replace it with a B.S. or a Techumsa 4 cycle.Am I going to have to buy a special clutch for whichever motor I choose since it will be a four stroke?Will a two stroke clutch work? and lastly it appears that there isnt a transmission in it like the max or the argo transmission.It appears to be two belt pulleys with a main drive belt off the clutch in the middle.Does anyone know what Im looking at with this system and can someone explain how it operates and is it a reliable system? |

Chris, We have a Roughrider my boys have been working on for a while. It does drive with the two belts. When you push a handle bar down half way it releases tension on the belt and stops drive to that side ,then push all the way down on the handle bar and the disc brake locks that side for a sharper turn. It doesn't have a reverse gear. One nice thing about the Roughrider is that most of the parts are not specially made and can be bought at a bearing supply store. |

Thanks for the reply,I appreciate it.
Im kind of lost with this thing.The body is really nice,has no motor.I was just confused when I looked at the drive train.As a matter of fact I cant even see a disc brake mounted anywhere in the tub.everything else seems to be there though.What kind of motor do you have in yours?And would there be anyway you could send me a few pics so I can look at yours and compare what I have to yours? |

There is no disc brakes. The brakes are a "band" type, like you would find in an automatic trasmission.
The original engine would have been a JLO 230.
The use of belts, instead of a transmission, is really quite cleaver. If you know how the belt engages the auger on a snowblower, then you know how it works in the Roughy! Theres just two systems instead of one (one for each side). McKee Brothers were manufactures of a full range of snowblowers, and they just pulled parts off the shelf to build the Roughrider.
Unfortunately, because the primary drive belt runs down the centre of the machine, upgrading to a twin cylinder snowmobile engine is impossible (not enough room). But the machine is so light that any 2 cycle single cylinder from any old snowmobile, will get it up to 30mph easy.
I have many manuals and promotional pamphlets I could scan for you if interested. bookm97@yahoo.com |

There was actually a Rough Rider made that had disc brakes instead of bands. One Rough Rider on ebay had the bands that I saw in a pic. My machine had disc brakes in place of those bands/drums. Must have been two different runs of that vehicle. The previous owner of my Rough Rider said it was a 1964, but I don't know when those vehicles were made. |

Ahh yes. I 'spose some twins WILL fit. I just opened the hood on my '79 Polaris 340 TXL to see if it would fit and... not even close! LOL. But I'm sure there are other small twins that would. I have to start scowering the countryside now, 'cuz I just broke my JLO in a BIG way!  |

We've grown tired of two strokes. Smoky, rough running, fouling plugs, etc. Get yourself a new or lightly used Honda 4 stroke from ebay or something (like I just did)
F the BS motor. Won't go wrong with a Honda |

Sorry, not a 4-strike fan. Had a 440 Argo years ago and that speed is addicting (qualified drivers only). I'm on 3 lug FatCat floatation tires (on Roughrider), and I get a huge thrill bouncing around the coutryside, hehe.
BTW, at 17 yrs. old, how can you have grown tired of ANYTHING! LOL, JK

A lot of troubleshooting on an old Sachs can make you tired of it.
Like when it quits and refuses to start when you're out on a lake. Remind me to get collapsing oars and install blocks. |

forgive the weird order in my replys to posts there in wrong order in my yahoo mail:
sean i use a tape mesure to figure out how long or wide a motor can be and stil fit my aatv's,
before you take out that sacks and bury it in back yard take your tape mesure and go from inside edge of engine cluch (motor side) and mesure to atv hull on recoil starter side of your engine, subtract a half inch for safe clearence and write this number down in walet, every time you think you see a nice motor take out your trusty tape mesure and wallet and you will soon find engins that fit your buggy
(sometimes how tall makes a diference too)
just another of my ol rules of thumb,~ got a milion of them! |
