PostSubject: Richie's Murray Widebody- "Orion"   Mon May 22, 2017 11:27 pm

So I went to a fellow atltf member's place and picked up some stuff...

In that stuff was this...a 90's (I think) 1st gen Murray Widebody which had a MST206 and Tecrapsuk engine



Before I even got the thing running I threw on these (which I got on rims from that same guy). Wheels came off no trouble! I also put some cheap go kart tires on the front because I had them lying around. I hadn't even pushed the clutch pedal in yet and this thing had decent tires!



I swapped on a Briggs 14hp 28ci OHV(also got that from him) because i hate any vertical shaft tecrapsuk(besides their Vtwins)



At first I had major issues with the needle and seat not doing their job...





I swapped the seals and gaskets from this carb to another I had, this one runs lean and therefore hot but it's been improving. At first the muffler would glow red with the lights off. I actually drilled out the side of the muffler to where it has a like 1" hole instead of all the tiny holes to let some heat out. I also undickered the muffler bolts by tapping the exhaust adapter holes to 3/8" and using some allen head shoulder bolts I had.

She's Hot!



I love unibits lol, just let em eat till the hole is the right size. Muffler is only slightly louder and sounds better than it did before



I had to modify the exhaust a little because of the hood, add a little piece of tubing to direct it out under the hood. I only had the stick welder so it came out a little messy, but it holds.



So whatcha think? I have yet to pulley swap it, add a foot throttle, or wire anything besides a kill. In fact I really don't wanna pulley swap it. It looks like a bear to fit a bigger pulley on the front and there's no way to really adjust any pulleys to make a stock belt still work. If I do pulley swap it, I'm thinking 6 to 4 pulleys.

Yeah, but there's no place for extra idlers and belt keepers and such

Well, as a few of you have seen, I put up a video of my first romp on Orion. Didn't get stuck and actually barely had to rock it. she's pretty mint

So the next thing I really gotta do is a pulley swap. I have an about 7" cast iron pulley that should be perfect. Problem is, I don't have a 5/8" bore pulley, so I'm thinking of using the center of the stock pulley with an old engine pulley or something. Not sure what the speed is gonna be exactly, prolly somewhere over 30. But I'm fine with that. The brakes on this thing are actually pretty decent. I'll be doing some math on speeds here in a little bit.

I got a bunch done on her in the past few days. Pulley swap is done (besides a few belt keepers) I think, I might use the old deck drive pulley on the back rather than what I have now.

Old pulley gave me a little trouble, had to heat it with the torch and give it some crayons to get it to come off. Even with the wax it took a well educated hammer to drive the input shaft out





Drilled the spot welds out of the old pulley and knocked it off of the hub, then i put the hub on a bolt in the drill press and filed it down to where I could fit an idler pulley over it snugly (sans bearing) and then drilled holes in the hub to bolt the pulley onto. Have you guys noticed I'm kinda cheap yet?   Literally the only pulley I have ever bought was the idler for the clutch on MUTT





So now that I had the rear pulley done, it was time to swap the front. I was kinda dreading this moment but it turns out Warren was right, you can just take your grinder to the underside of the thing and just ask it nicely (with a cutoff wheel) and it will fit. This is an 8" cast iron pulley, my rear pulley is 4-1/2". So that gives me a just under 2:1 pulley ratio.



Somewhere in the midst of this I wired her and stole a battery out of my Snapper. Believe it or not, the headlights work! (they are on 12v rather than the stator output btw so they are waaaaaay brighter) I welded in like 2 belt keepers, added an idler to keep the belt off the shifter, and off I went. She throws the belt when you let off the clutch after a few times, I'll just keep adding keepers till it stops. This thing is REALLY fast. I think like 30mph, maybe more. Brakes still work ok at speed, surprisingly enough. Right now I'm making another gas pedal, the bike brake I put on just doesn't work for me.

Yeah, they're pretty much the same tractor! This one might get a governed 18hp oppy if I can get a carb together for it. The single just doesn't do it for me, lol
