Justice77 163 #1 Posted November 7, 2018 On Sunday I mocked up this 70's YardMan. I also found a guy not too far away who has a 3000ish sq. ft. gokart shop. He set me up with used rear axle assembly w/ everything I need on it, + Hyd. disc brake, 4 alum wheels and a junk frame with all of my bracketry and other usable components. I'm pretty excited to get on this project. Have a Peerless 700 series 5 spd in nearly new condition for this as well. Likely power will be a 16hp twin from a Simplicity that is in line as next project after this one. The Simplicity is a larger (medium?) frame machine which I'm hopefully picking up power for this weekend - a 600cc in-line 4 Suzuki. 11 2 Share this post Link to post Share on other sites
ebinmaine 67,502 #2 Posted November 7, 2018 That looks pretty good all mocked up. Can't wait to see the finished product. Share this post Link to post Share on other sites

I made some progress on this project recently. Rear axle set. Trans tunnel cut. front axle cut. Should have front tires soon - they're 2" wider than the ones pictured. Adjustable steering geometry next, and I really need to decide on an engine. Right now I have options of an 18.5 hp Briggs single OHC, a 12.5 opposed twin flathead, and a 16 hp twin. I love the sound of a twin, esp at idle... I'll browse CraigsList for another week or so.... Every so often I see a Craftsman mower w/ a 21 hp or more v-twin Briggs for around $200. This would be ideal. https://imgur.com/a/DekcN2k 1 Share this post Link to post Share on other sites

Got 8" wheels and mounted 16x7.5-8 tires (see my pre stretch idea to get bead to seat easier). Scratched my head a bit considering how to get this low, tires to clear fenders and keeping seat pan above tops of tires. I cut lower outer fender section off, flattened the step-down, then got it all to fit back together nicely... friggin' miracle. I'm happy with my solution. If I were more experienced with this I might have chosen a different donor frame. Made front axle plates on friends ironworker. Verified my pre-set 10 degree caster and camber and tacked in place. Have 2 right hand spindles as that's what was in used parts bin and they are heavier duty than left side - 3/4" inner spindle shaft dia, and 5/8" outer so I'll have to mod. one dep if I go w/ front or rear steer set-up. Adj. camber w/ heim joints and caster - my plate is set at + 10 degree and the slot punched in to top of plate allows +9 to +15 degree range. Wedge adj. by arranging the washers above / below. Need to start considering an engine. I don't have a sub 17hp single, or a + 8hp flathead per build rules... To keep going forward, deviating from build rules I do have a 17.5 ohv single, and an 18.5 ohv single. + I have a 12.5 f.h. opposed twin and a 16 f.h. opposed twin. I can also get a 20hp ohv v- twin. If any of you weren't sure if you would definitely race this, which engine might you go with? Is there a brand new < 17hp ohv, vert. single I might find on a Black Friday or Cyber Monday sale? New would be nice, but I don't want to spend much...

ebinmaine 67,502 #5 Posted November 24, 2018 Cool little buildup. HF have any engines on sale? Other than that maybe just keep watch on CL. Share this post Link to post Share on other sites

Can hardly wait to blast out of the garage with burning rubber smell following me. I just decided I'm going to pull a perfectly good 18.5 hp ohv single out of a Craftsman lt1000. It has working elect start and alternator, new battery, working wire harness, clutch odds-n-ends, cables, v gauge, and it's right out back. Why wouldn't I... That was a $150 craigslist steal as it's mint / hardly used. Was planning it to be woods / mud / yard machine, but ... one project at a time. An easy sacrifice considering everything I will use from it. I just finished pulling engine and have mocked up in blue machine. Lots of room Edited November 24, 2018 by Justice77 4 Share this post Link to post Share on other sites
Justice77 163 #7 Posted November 26, 2018 Got my discretely hidden frame reinforcement all welded, trans plate lined up and tacked in, trans mounted, chain and tensioner installed. Now considering where battery and fuel tank to go. Maybe if I inch cowl back a bit they'll fit in there. Next to reinforce cowl and set up steering column. Column runs straight in to engine head so may need to use a u-joint or 2. Pics in reverse chron. order. https://imgur.com/a/DekcN2k 1 Share this post Link to post Share on other sites

Justice77 163 #9 Posted November 27, 2018 It dawned on me that this is like building a little race car. Not that I've done that before but I sort of get the idea. 2 Share this post Link to post Share on other sites
Justice77 163 #10 Posted December 5, 2018 (edited) Got a bit more done this past weekend. Trans plate, trans, chain tensioner mounted. Engine plate and engine mounted. Cut out slot for sprocket and built guard. Also finished full welds on fender mods. Now waiting for more steering components for pitman arm I fab'd, drag link... should have bellcrank fab's this weekend and hoping for full operable steering by Sunday evening. Also due this week is engine pulley and trans pulley and some clutch components.. Next week will be thinking about clutch, brakes, throttle, gas tank, seat and battery mount. Getting closer to a test drive! Edited December 5, 2018 by Justice77 3 Share this post Link to post Share on other sites

The Tuul Crib 7,336 #12 Posted December 6, 2018 Hey is that a Corona I see?! Share this post Link to post Share on other sites
Justice77 163 #13 Posted December 18, 2018 Lol... Yes - Corona Light aka "Work Beers". Took some time off from this project due to tweaking my lower back then had an infected abscessed tooth... Ugg. I got some stuff done on Sunday though, inc. pulley alignment and steering components fab'd and installed. Steering was a bit tricky and will probably be modified yet again. Prob. start working on clutch next. Was planning to fab my own but saw a fancy one online and impulse bought it. I am not sorry :). 3 Share this post Link to post Share on other sites

Justice77 163 #15 Posted January 1, 2019 Thanks! Made more progress in last couple weeks. Made a cut-out and cover (from cut-out) for battery, Trans cover out of Craftsman louvered hood, re-did steering bell crank and pitman arm for THE 3RD TIME - and I have determined that the 3rd time really is the charm. I also got the clutch assembly mounted and a nice working linkage to a clutch pedal. Have belt installed with keepers on both drive / driven pulleys. This past Sunday I got brake caliper mounted, and now need to make a brake pedal and mech. linkage to master cyl. The list is getting shorter week by week. Hoping to transfer wire harness today and get brake working. 6 Share this post Link to post Share on other sites

Justice77 163 #17 Posted January 3, 2019 I think just a handful of list items left to do before test drive. I did fab a brake pedal and got it and master cyl. mounted and linkage done. so... Fuel tank Throttle assembly Mount steering wheel Wire everything Battery clamp / secure somehow Tether kill switch Hood / grill bracing Some welding here and there... Oh, how could I forget - Drink holder. Lol... 1 1 1 Share this post Link to post Share on other sites
