I know I know; worthless without pictures, but a few weeks ago I think I finally compiled all the parts I needed [seemed like every part I took off needed to be reworked or replaced, then putting it back together kept finding things!] yet, I haven't resized many pictures.
Still decapitated, but the engine is back in the bathtub [the tractor's "uniframe" not our bathroom which would provoke some strange looks from my wife: for your own safety nothing bigger than a carburator gets cleaned up in the house; safer yet, forget the carb too].
So far it has
All the large castings "boiled out" (this makes clean up and assembly much nicer!) in town
New main bearings [these are ball, else it'd been rote]; a bit of a bugger to press these on the crank, but I heated them to about 250F first so not too bad
Crank ground [I didn't think IHC did Tocco journal in '29, but the shop said it was HARD]
New used rods with likely 75% babbit instead of 20% and missing chunks too on 2&3; about 60% equivalant on the shim stack [plastigaged to .002-3] with .005 off the crank.
New seals on both ends, and several gaskets I needed to make along with a bunch of new ones and NOS
New pilot bearing
New clutch facings; pressure plate completely disassembled to remove mouse fluff and rusty scale [likely result of mouse pee]
Clutch arms tuned to throwout [recommend this is done on the bench, in retrospect I'd either agree or cut larger reliefs into the pressure plate/spring housing as well as wrench flats on the female side of the "studs"]; linkage tuned and new pedal spring - several points in the linkage should get a date with the welder and built up, but that can be done when it has it's own power again.
Flywheel face cleaned and scale [like pressure plate face] removed
New throwout grease-tube [a bugger to put in without the original swivel fitting!]
Steering arms removed (.002 press fit
) and bushings added; new pins made (I really need a mill and lathe here, but the VoTech in town liked the project)
New manifold water injectors being made at the Votech too
10 bolts/studs removed (litterally drilled and pealed out thread by thread; neither straight nor spiral screw extractor would budge a one, so after peeling enough thread for a tap to find the cast and bite the grade8? instead that pushed it out without too much damage) from manifold. A can of oven cleaner, a can of carb cleaner [the former much more effective, but I didn't want residue left behind] and much elbow grease later [on top of much to disassemble the selector plates in the first place], and most of 50 whoknowshowmany years of carbon deposit removed from intake.
3 NOS sleeves/pistons with weird mix of preserving lube [cosmoline perhaps] and surface rust] nearly cleaned up - the guy selling never recieved the 4th several years ago; two sets of oringal sleeves/pistons only about .010 on the sleeve, I'm still debate which of the set and change everytime I look - ready for new rings.
Head redone, .010 off block face and manifold face, 3 new valves, 8 new guides!
Cam shaft, bearings, lifters and gears, cleaned up and well coated in assembly lube
Oil pump de-"slimed"
Oil filter too (anyone ever see a Purolator with a T-Handle on top to pull a plunger inside the element? I think I have somewhere, but not on one I've ever had apart)
Oil Lines blown out
Broken bolts on housings drilled and retapped.
A little TLC on the impulse, and file on the points, the mag has pretty good spark - not sure how it looks at engine rpms, but have a rebuilt one located.
Being only a month or so early of changes for 1930 [Velumoid instead of cork on the bellhousing etc.) , I managed several times to make gaskets to the wrong thickness (not quite that anal to redo such things if they work fine, but this messes up mounting other things later) and have to disassemble, remake, reassemble - you'd think I'd learn, but this skull is thick.
Sleeves need to go in now, and pistons too, but shimming the rods with it sideways was sure nice; the ground crank [several thou out of round] sure made it nice to plastigage too. Next is the governor, which also has the mag drive shaft and support base. I really should have found a new bushing for it, but it didn't look horible and not to much stress is applied there.
Hopefully a bit less time between this and the next update - it looks like Mith built a tractor from scratch while I was rebuilding this one!
Not that the others didn't have a fair share of rain, mouse pee, or both too.
