[DQ'd Member Banned] SebastianAlbrecht's Murray Widebody Offroad + Trail Mower [2019 Build-Off Entry]

Thanks. Yea the OHVs are pretty tough, I haven't abused mine too hard only because it has a helicoil. But soon as I change the head, look out. The only time (besides online) I've ever heard of a blown OHV was my friends
14.5 HP. Then again I've never had a 12.5 that was not a powerbuilt. B&S put a weaker connecting rod into the powerbuilt for some reason, probably for cheaper manufacturing. But for that reason I try to stay away from the
powerbuilts as much as I can. I haven't had any experience with the normal 12.5 so I guess my opinion only applys to powerbuilts. And yes, FF does abuse his pretty hard.

I have a fleet of OHVs, I like them allot better than the flat heads for power and ease of working on. I have not seen a 12.5 OHV of that vintage either, only the flat heads. I have a newer intek style one, but all the 12.5s I had were flattys.

I know right. I didn't even know 12.5 OHVs existed until now, except on a tecumseh.

Same reason I like the OHVs. Strong, powerful, easy repairs (not that flattys aren't), and of course, they sound better (no offense to the flatty fanatics).

Interesting!! I guess that it's a 14,5HP with the dumb HP Decreasing gasket!

I never worked on a Single OHV before, hope it's easy!

Just got some Lit Steel Pipe outta the Scrap Bin @ Work & want to build a Stack for it!

Yea that is interesting. And yes they are very easy to work on. The only real difference between the two are the valves. Just be sure to check and/or adjust them at least once a year. (Top valve is .004 and bottom is .005). A
stack would look pretty cool on it. I was going to put 1 on mine until someone said something about if it flips it could damage the head.

How about putting a little flap on the top of the stack like the old tractors have... just an idea.

yeah, might do it! IDK jet! Need some of the Pipes for the AYP too & I might do some muffling to the Widebody, but IDK rn, cuz I love loud Exhausts!!!

Well I planned on stripping it down this Weekend, but we got temps below freezing, so I decided against.....

Scored me these Pipes outta the Scrap Metal Bin @ Work!



And mocked up a Stack for the Widebody!

Pretty cool! It looks when you steer it the stack might be in the way... or am I just seeing things.

it was just a quick mockup without any measurements & stuff, just to look how well the pipe fits the Widebody..

Ok. Yea I do that all the time lol.

That should do well.

Well, it was 8°C outside today and no wind so I decided to use the 1 1/2 hrs after work to strip the Widebody down, since I didnt got that done at weekend!



everything is pretty rusty, but WD40 did a great Job! Didnt needed to take the Angle Grinder out, thanks WD40 & the Impact!

Need to figure out how to reinforce the frame next, & clean it up so I can weld it, and get me some box steel!

have Angle Iron and flat stock lying around, but IDK how well I can reinforce that C channel!

The Pulley is rusted solid to the MSTs input shaft, so I sprayed WD40 on it!

Ordered some electrical crap for MW!



Will add this thing to the Dashboard

Nice work! With some good reinforcing the frame will be pretty solid. What is the port on the top right of the electrical panel?

USB for charging the phone...

Awesome. Looks just like my murray. Rusty, dirty, and torn to bits and pieces lol. You'll definitely need frame reinforcements, those murray frames are weak as crap. My brother cracked and broke his frame in several places. Had to brace them until we can get them welded. If candle wax and the torch doesn't work on the stuck tranny pulley then you have to get a new input shaft. Gotta get a new one for my murray.

"WD40 and impact". Sounds just like me lol.

RN I have no clue how to reinforce it, since I cant just weld stuff outside since I want to reuse the deck lift lever, I cant weld stuff on top since it would misalign my shifter and lifts the body, I cant weld on the downside since there R all the mounts for Transaxle & stuff, I cant weld inside since there's the steering & stuff & other mounting brackets going on...

My last Input Pulley I dumped a waste oil and heating oil mixture into the pulley, after it was penetrated with WD40 several days, made a fire in the pulley, and then took me the pin outta A FNR Diff & Beat the crap outta the thing til the Pulley was fully deformed but I got it loose & was able to reuse the center for my new pulley!

I'm gonna try to bolt 2 steel plates on the bottom and 1 on the top in the back. If it doesn't do the job, well it's back to square one.

my input shaft is shot.

Sounds like it might help a tiny bit!

IDK RN in what shape my MST is, gonna look @ it when I take it apart

Scored me this Stuff today!



Prolly welding a Frame outta that box steel & then cutting up the old frame & welding it into the new Box Steel Frame!

This Stuff is pretty sturdy so I guess that Rig wo'nt flex then after all!


BTW: I need to get my Gas Sweeper going to clean the front yard! Looks horrible with all these Leaves & stuff & rusty junk & old grass outta Mower Decks lying around!

I knew there was something wrong when I let the clutch out and it sounded like tttttttttttsssssssssssssssojjjjjjjjjjjjdoddddddddddddddddccccccccccchhhhhhhhhhhhhhhshhhhhhhshshshshhskkkkkkkkklawaaaaaaaaaaaaaacscssseeeeeeeeeeecccchhhhh...lol.

Yummy! grinding gears!!!

Or gear shafts...

Box steel for reinforcing looks good. How about making a subframe to go inside the stock frame? That would be slightly less complicated but would achieve the same result.

Impossible to do since I need to change everything then... Will take a closer look to that Rig soon & figure out a final reinforcement plan!
