Hi, I am trying to decide if i want a 70D or not and i have some questions:
1.)How can you tell a OEM flywheel from a Taper-Lock Flywheel by looking at them.
2.)If it has a OEM flywheel, by looking at the crank, what are some easily visible signs that even a taper-lock would not work and that a whole new crank is needed? In other words, how bad is too bad?
3.)I have been unable to find out what a good 70D, p.s., good tin, useable tires, both motors run good, not painted up necessarally (but isnt all cobbled up and is origional), goes for. Has anyone seen some sell at sales and such and if so, what did they go for? Thanks alot,
chaz aka "Tractor Boy"

There is a wide variation in prices depending on where you're located. They go for about $2000-2500 (in the condition you describe) out in the Western and Midwest. Check www.atis.net classifieds, and 2-cylinder magazine. Here in Maryland they seem to command higher prices. My local dealer wants $3250 (down from $3500) for one not as good, with a "weak" pony. I recently paid $1650 delivered from Pa. for my 70D with a broken ring gear tooth and a bad pony but a good diesel engine, tin, and tires. A repainted 70D with no 3-pt and old tires went for $4200 at a Dennis Polk auction in Md. last year.

The taper-lock flywheel is three pieces. There is a tapered sleeve that fits on the splines of the crank, the flywheel without splines, and a large square nut on the outside. We have the poured steel flywheel on our taper-lock, so the flywheel itself does not have any split in the hub or bolts to tighten it. However, it was possible to have the OEM flywheel machined to work with a taper-lock, so its not necessary to have the steel flywheel. I can't tell you how bad is too bad, but our's was very loose before we put the taper-lock on. The reason we had to get the steel flywheel was that we had replaced the OEM bolts with fine thread bolts and used a 1" impact wrench to tighten them, which cracked the flywheel after we ran the engine for a while. At that time, the flywheel was so loose that it would come off even when the OEM bolts were tight.

Looks like you got your answer about the taperlock flywheel. They are nothing to be afraid of as long as they are properly installed and tightened. We have a 730 diesel that has had one for close to 15 years. Still works fine. They will work on some really bad splines just fine.

Chaz:
I don't know about your flywheel question, but I have been looking at a 70D that a dealer in my area has. it is in good running condition but needs nes paint, and seat cushions. no 3 point. they are asking $4000 in East Central IN.
