BurtB 91 #1 Posted Sunday at 05:18 PM Google Drive link to pictures, feel free to comment. Been a while since I was on the board or have worked on our tractor. Got stuck triaging the entire rest of our little playfarm such as roofs, foundations, and electrical. Excuse the mess in the garage, still a work in progress, but at least the roof isn't going to collapse and it doesn't leak. Anyhow, back to the tractor in question. It is a 69 GT 14, not that I've verified the year. Goal is to restore mechanical function to new/near new. Engine will be rebuilt, transmission rework very likely, wiring redone. We'll also be printing some emblems/instruction panels. If needed, I'm hoping I may be able to bore the engine on my lathe but we'll see. As for paint, we'll likely just be painting the engine. Everything else will get oiled and polished with orange rust being converted. My son (15) is also using this as his FFA project and is the one taking pictures. He will be posting as well and his uname will have Strudel in it. One of my goals is for him to learn technical communication/research/etiquette. Please feel free to address him and send him on learning rabbit holes. Engine is out of the tractor, I see what looks like an impression of the spark plug ground on the top of the intake valve. Exhaust manifold is looking like some sort of BIP frankenstein assembly. Have spare carb, carb rebuild kit, fuel pump rebuild kit. Today I have to go pick up a fruit press: our apple trees responded with a bumper crop after their first pruning in a decade. Hopefully we will do further disassembly of the engine this evening and I'll get some measurements. Comments/questions/suggestions are very welcome. What is the best way to access the transmission and how much should we disassemble to get there? 3 Share this post Link to post Share on other sites

Strudel 2 #3 Posted Sunday at 05:28 PM Hello, I am the Strudel he was talking about. Like he said, this tractor will be for working on the playfarm and also to get some hours in on my SAE for FFA. We got the tractor last year, from some guys who seemed to do tractor derbies. Luckily, this one was not put through the wringer. It used to run before the winter, but that doesn't matter either way since we're going to re-do basically all mechanical and electrical aspects. 2 Share this post Link to post Share on other sites
Strudel 2 #4 Posted Sunday at 11:51 PM (edited) Alrighty, so, I'm wondering what this wear on the top of the piston is from? I think it's only on this side. If you'd like to access any other images, please refer to the top post for the link. Edited Sunday at 11:52 PM by Strudel I goofed up and originally put "files" instead of "images."

BurtB 91 #5 Posted 13 hours ago Cylinder bore is 3.5045 at the largest. This is deep in the cylinder perpendicular to the crank. Has maybe .0005 taper on that axis. Parallel to the crank high on the cylinder, we get 3.5022. Perpendicular to the cylinder, high on the crank, 3.5040. So, bore exceeds wear allowance of 3.503. However, we're okay on roundess as it's less than .003 OOR. Taper is also okay as it is .0015 at the worst when measurements are vertical. (.002 allowed). Rod journal on crank isn't tapered. However, it is 1.4994 - 1.4987. 1.4990 is the minimum. We're also . 0007 OOR with . 0005 being allowed. Valve guides check right at nominal .3125 in all locations. Might be a hair larger on the exhaust side, but not enough to matter. Haven't checked head flatness yet. Took some measurements, I won't be able to fit the block on my lathe carriage for line boring. Also don't have the grinder to handle the crank. Can't cheat these dims without burning oil and wearing out the crank, can I? Share this post Link to post Share on other sites
