Starter/Cranking Speed Problems
When the engine has not been run for a couple of hours, and then a start is attempted, the speed of the starter is very slow, almost like the batteries are low. But, after it has cranked for about 10 seconds and the key is turned off for about 10 seconds, and I attempt to crank the engine again, it cranks at normal speed and the engine starts immediately. It ALWAYS cranks slow the first time, and ALWAYS cranks normal the second time.
I was thinking that maybe the solenoid contacts to the starter do not make sufficient contact to provide the needed current during the first try. But, due to heat generated during the first crank attempt, the solenoid moves more freely(heat expansion of parts) on the second attempt giving full contact and enough current for the starter.
Any suggestions. Batteries and charging system components are all new.

Well, I had a similar problem, but it ended up getting worse...
As it turns out, the starter brushes were worn and the brush holder was cocked too. Has new brushes ans a brush holder installed in the starter, put it back in, and starts like a dream!

I had the same problem, turned out to be the commutator on the armuture was melted. I did not mess around, I had the whole starter rebuilt for about $100. It is not worth getting stuck somewhere.

Starter/Cranking Speed Problems
I just put in a new starter... and it is still hard starting. The start cycle was fast some of the time. But, because the engine did not start for about 5 tries, one time the starter completely stopped. I turned the key off and then on again, and the speed was fast and the engine started.
Batteries are good, starter is now new, and glow plugs are good and properly cycling.
