Time? It could be done in a day if you had all the parts and a full machine shop at your disposal. Most take anywhere between 1 week and several months depending on: 1) when your machine shop can get to it, 2) How long it takes to get/afford your parts, and 3) how much time you have to devote to it. On my 1939 9N, money was tight so I delayed getting parts and taking it to the machine shop and once I got it to the shop, the poor machinist's dad died and he got backed up. Since mine was a hobby, and not an emergency - I let him clear up his back orders and gave him plenty of time. From the time I split my tractor, to the time I got my engine back (today) as about 3 months. It will probably take me about another few weeks to a month (I am taking my time) to get it all back together and ready to test fire. The fastest I have rebuilt one was about 2 months from start to finish - most was waiting on the machine shop, but I am very meticulous and fairly green. Cost is greatly dependent on your level of rebuild. Full blown rebuild kits are about $400 or so, with just rings and bearings going for around $200 or so. Machine shop work runs about $500 - $750 or so depending on what you have done and any "extra" work it needs. My engine I just got back was $630 and it included grinding the crank, surfacing the flywheel, replacing the starter ring gear, complete valve job and seat grinding, vatting, magnaflux, freeze plug installation, installing and honing the sleeves, piston pin replacement and fitting, size the big end of the piston rods, piston and rings replacement/sizing, heli-coil four head bolt holes, rebuilding the oil pump and sizing the bushing, and misc. shop supplies. He usually does much more than he charges for, and always does a great job so I always use him. Overall, I spent about $1k for all parts and machine shop work. HTH, Dan
