kpinnc 14,214 #102 Posted April 13 (edited) I didn't a little test fitting and a few little things today. I stuck wheels on it just to make it look sorta like a tractor. Rears are in primer and the fronts are the tires I'll be using but the original wheels are a disaster. More on that later... I repainted the tank using Rustoleum clear. I guess it's decent, but doesn't compare to the luster of the 2K clear. It may get a coat later. I really like the lineup of the wheels front to back with the wider axles. It's hard to see in the picture, but the wheels are perfectly online from front to back. Added a little bling on the oil fill plug. Now I can hold the extention with a wrench when removing the plug. I always hated how the extention always breaks loose first! The front wheels... Somebody did some hillbilly engineering from way back in the swamp on these. The bearings were replaced with a bronze sleeve and full length bushing in both wheels. One was damaged a bit and I had to round the hub back out. Test fitted a crap bearing just to see if it was snug. These wheels are really rough. They will get the workover in the next few days. Anyway- she's coming together. She has her flaws, but will look decent when finished. The pits just add character! Edited April 13 by kpinnc 2 8 Share this post Link to post Share on other sites
AlexR 1,686 #103 Posted April 13 Looking great!!! Those tires are definitely the right ones. Going to be a beautiful tractor when you are done. 2 1 Share this post Link to post Share on other sites
kpinnc 14,214 #104 Posted April 14 There was one more thing I had hoped to save. It was badly bent and had to be straightened and a new nipple welded on. Took up the rest of my afternoon. It isn't perfect, but it looks good enough. 1 7 Share this post Link to post Share on other sites

kpinnc 14,214 #108 Posted April 19 Just to say I did something today, I tried a new wheel color. 1 5 Share this post Link to post Share on other sites

Years ago when I bought it I remember it stood out to me that it was different. I straightened it up the best I could and added another baffle in the neck when I replaced it. I hope it works well. 3 Share this post Link to post Share on other sites
kpinnc 14,214 #111 Posted April 20 Well I got the engine ready to go to the machine shop. Took it all apart, cleaned the block. Also took the donor K181 apart for the piston. The piston looks brand new with the only scratches being what I put on it removing the old rings. Also- the donor engine had an aluminum pan. Full size just like the cast version. I've never seen that before. 3 5 Share this post Link to post Share on other sites

kpinnc 14,214 #114 Posted April 30 4 hours ago, WHX?? said: That's bizarre... crank is on the way. Thank you! I have found a NOS 2.885 (.010 over) piston and ring set. Probably won't be installed for a while until I get the crank ground so I know which rod to get. That matches what my block was bored for, and keeps the "smaller" original bore as well. 4 Share this post Link to post Share on other sites
kpinnc 14,214 #115 Posted May 2 Correct piston came today. Needed to be cleaned up a little (light oxidation because it had been out of the plastic), and it looks great. Matches the bore perfectly. Little by little! 2 3 Share this post Link to post Share on other sites
kpinnc 14,214 #116 Posted May 25 (edited) Still haven't taken the crank to be ground so I fixed another issue: the left front spindle was wallowed out enough to let the wheel wobble a bit, so I welded the hole for the roll pin up and re-drilled it. Surprisingly it all worked out and fit perfectly. Since my front axle was one of my clear coat guinea pigs, I had to strip it back to bare metal and repaint it. The 2 part clear coat is good stuff, but it shrinks more than a weenie in winter. The base coat needs to be properly cured before applying it. Anyway, I used the rustoleum clear over the base and it looks good enough. The spacers on the spindles are just temporary. My original wheels are gonna take a great deal of work before I can use them. Edited May 25 by kpinnc 1 5 Share this post Link to post Share on other sites
kpinnc 14,214 #117 Posted May 25 (edited) Not much, but it's on all fours. Still gotta finish the rear wheels. The fronts are likely temporary, but the originals are nasty and will take a while. I got tired of it being on the stand and at least it looks like a tractor a little more now. Haven't even started the sheet metal but I set the hood on for grins...

At least I could clamp it on the drill press and make it work. The steering shaft is bugging me. Where it comes through the tank at an angle makes it a puzzle on how to keep it from scraping and making a mess. To be such a simple machine compared to a classic tractor, it has plenty of fickle little issues to get around. Edited May 26 by kpinnc 2 Share this post Link to post Share on other sites
kpinnc 14,214 #121 Posted Wednesday at 07:50 PM Took a while, but I now have two K160/161 cranks ground and polished. The original crank from the 701 was .013 below minimum when pulled from the engine. It looked very nice but probably would have had some slap if used as it was. Talk about well worn! It was ground to .020 undersized. The second crank came from @WHX?? and it was ground to .010 undersized. Now I just need to find a good connecting rod, and I'll finally be able to get back to the 701 build. The shop sure knows how to make them pretty! Cost me $85 for both since only one machine setup was needed. Total for engine work is just under $200. That's an oversize cylinder bore, recut valve seats and valves ground, and grinding two cranks. Not too bad for today's prices. 1 6 Share this post Link to post Share on other sites
