B rebuild progress

Hope you don't mind but I resized the photo. Good start.

Coming along fine.  Looks like the engine is ready for use.  

Started out intending a bare minimum rebuild.  This was a "pasture find", which is like a barn find if you had gone and dumped a cup of water down the exhaust pipe every month.  Two cylinders were heavily corroded.  Ended up with a complete rebuild kit and had the crank ground and the head surfaced and valve seats ground.  Carb is in surprisingly good condition.  Crank pulley was seized in place and broke that early in the process, but found a replacement.  Have a donor C that is in worse condition to rob a few parts from also.  This is getting the mini one wire alternator upgrade since the generator would have needed a rewind.  

great progress! I'm also starting a B project can wait to hear the tractor run.

Glad to hear it's back running!  Can't wait to hear mine again, been many moons...If I'm following, sounds like the clutch works OK without the engine running, but not doing it's job with the engine running...  (spitballing from here down)  Only thought I have before re-splitting is backing out the clutch rod a turn or two.  Should give it a little more travel.  Just have to make sure the clutch pedal still hits the torque tube stop at full travel (per the manual).  Otherwise its binding up elsewhere.  A tight bushing that is not spinning true enough is a possible explanation.

I need more info.
I doubt pilot bearing itself is the problem from your testing.

Did the torque tube resist being snugged to engine for last 3/8" when reassembling?

If yes,overpacking crank pilot bearing recess causes a problem like you describe. It prevents trans input shaft from fully inserting into crankshaft and puts lots of rearward stress on input shaft (killing trans front input bearing) and causes the input shaft to act like its seized to pilot bearing - which may have been partially pressed out of the crank by hydraulic pressure when torque tube was bolted up. Unbolting torque tube 1/4" may drastically improve things to indicate overpacked crank recess is the culprit. (Use method below to spin trans/engine -starter won't get proper flywheel ring gear mesh with torque tube moved back).



Otherwise...with engine not running,does the trans shift into gear?

No? Note, may have to jack rear wheels off ground and rotate wheels slightly to help slide into gear (old trans not fine mesh). Figure out trans problem(s) to see if cures shifting problem.


Yes?

Good. Put trans in 3rd gear, pull spark plugs, jack up rear and see what sound/resistance you have rotating trans/engine spinning wheels.

Now repeat while pushing in clutch. Engine should stay still. If not, clutch adjustment wrong, clutch wrong size, clutch rusted to flywheel, and/or pressure plate somehow pinched clutch disc to flywheel(disc od too big).

are you doing this at full throttle or 800 rpm ?  There are many tractors that will have a "SLIGHT" drag if your running at a high speed.. I always drop down under 1000 rpm to shift.

not a FIX, but sometimes you can pull up on the hydraulic lever ( pto engaged) to LOAD the pump and the shaft will stop so you can shift..

Sometimes when you install a bushing it distorts in the process. May be a high spot  because of it. Only fix is to pull the motor and look.  Your adjustment of the pressure plate fingers could be an issue all so. Might be adjusted so tight they bind before completely releasing. Are the tips of all 3 fingers the same height? if one is doing less travel than the others that pressure plate by that finger isn't opening as wide. 

Ok, last pic for the season.  This is as far as I will go until tackling the back end, including the dreaded brake pins, next year.  Just finished up replacing the front spindle bushings, which was a little more of a chore than expected, but not terrible.  Made my own hub seal out of felt which worked well.  Also repaired a badly rusted front rim and put new rubber on them both.  5x15 tires, slightly larger and taller than what was on it, but I think they give the front end a beefier look that is good.

Luke what year is that old Falcon ?

Luke,  Thanks for what you are doing to keep my favorite alive and well.
