OutdoorEnvy 1,522 #1 Posted March 23, 2023 Hey folks, I wanted to post a recap of the C-100 save I did over the last year or so. Some may remember when I got this rig but thought it would be cool to have the progress in one place and maybe encourage others to not pass on a project. Also showing about the most budget friendly way to save one of these nice old machines and turn into a great user. So this is a 1974 C-100 8 speed that I got for $25. No implements, though it did have a mule drive. It sat for a long time with a blown engine. But this is the day it came home. Total cost/budget for this will be at the end. Engine tear down and inspection. Blown rod. Discovered this engine had been rebuilt before with a .020 over piston and .010 under connecting rod. There was so little carbon on the head when I removed it I figured the engine didn't have many hours on it before it was ran low of oil and that's what caused the failure. There was a nick in the cylinder wall but it was below the ring travel line. So I ordered a rebuild kit off ebay with the .020 over piston and .010 under rod. Cleaned everything up and did a valve job. Also cleaned and rebuilt the carburetor and all new fuel lines, and filter. Fuel pump was bad so changed to electric pump. Cleaned the points and the set gap. Starter wasn't working so took it apart and cleaned everything up on it nice and put it back together and worked great Now that starter was working and verified the engine ran well it was time for the wheels/tires. I got tubes for all tires and cleaned the rims with water and wet sand paper, 200 grit. They cleaned up nice! I'm always surprised how well old paint can hold up. Rear tires are Goodyear AG size 23x10.5-12. They were a little cracked but with new tubes they should be just fine. next was a muffler. It didn't have one when I got it. So ordered the cheap one and welded on some pipe with matching thread. Ugly weld as this was one of my first weld projects. But it's working. A trans fluid flush revealed a leak on one of the axle seals. So replaced that Well with new gear oil and everything greased up I washed it down and gave it an oil rub down. I've probably got around 10 hours running time on it so far but it is working fine. So here is the finished rig keeping it about as original as I got it. So cost for this save project is below. I didn't include maintenance items, like oils, and filters. Just the broken and needed replaced parts: $25 - Tractor $100 - Engine rebuild kit $60 - tire tubes, all 4 $30 - carb rebuild kit, fuel lines, and fuel tank valve $20 - electric fuel pump $7 - Axle shaft seal $18 - muffler and pipe Total is about $260 in this rig to have it a solid user. It was a fun project and I'm satisfied with how it turned out. Well worth the investment and effort to me. Thanks for looking! 6 14 1 Share this post Link to post Share on other sites

steelman 251 #8 Posted March 26, 2023 Very nice description of the steps to bring it back to life. Can’t tell if you stitched the seat or duct taped it but it looks much better. I have a C100 and it is a favorite of mine! 2 Share this post Link to post Share on other sites

Debating on a new seat or trying to source a local place that might be able to make a new bottom pad and cover. Top back pad is perfect. 1 1 Share this post Link to post Share on other sites
