On my 41 H I can slide the crankshaft in and out about three eighths to a quarter of an inch. Is that normal? If not how do I correct it? I have recently bought the tractor. It is not stuck and one of those tractors that "ran" when it was parked. But, I am still learning about two cylindars and what clues things like that mean as I disassemble it. Thanks for any help.

Johnny -- If you do not have the special wrench needed to loosen your flywheel bolts, go to www.jdhpubs.com and select the Restoration Guide, the "Read Chapter 1" section. At the bottom of the last page (page 8) you will see a home-made wrench that does work, and that you can make. Of course, you will need a socket to go with it that fits the nuts.

The second issue -- The I&T Shop Service Manual gives you only half of the story. Here is the entire specification you should apply:

Flywheel End Play -- The specification is called out in JD-4 with no instructions how to do it. In accord with Dir. No. 214 (repeated in Dir. No. 248); "End play can be taken out of crankshaft by loosening flywheel bolt nuts and inserting screwdriver in groove near end of crankshaft through slot in flywheel and prying toward the tractor." End play shall be from 0.005 to 0.010 inch. To take it all out may result in damage to the L.H. Main Bearing (FSB 96-S, 4-15-39).

Like Mike said .005-.010 and that is recommended in the I&T JD-4 shop manual. The I&T JD-4 covers your H plus other two cylinders, A,B,D,G,M,MT and worth getting along with other manuals if much work is needed to be done to get the H in shape. H operators manual OMR2011 and H parts catalog PC304 will be helpful also.

Thanks for the info. I do have the jd-4 book and found it on page 19. Next time I'll look in my books first!

That's not normal. It should be from .005" to .010" You have to loosen up the flywheel and slide it back on the crank farther. There are some notches in the flywheel and a groove in the crank you can get a pry bar in and pry the crank out of the flywheel then tighten the bolts and recheck. There is a special wrench made to get at those bolts I see them on ebay all the time. I don't know if you can get to those bolts without it or not ? I have always had one.
