Some of you are full of wisdom about older equipment.
I have a 85-3A Michigan wheel loader, and if memory serves right, a Clarke transmission. The problem has been ongoing for several years, (very low use machine) I'm sure a rebuild is in order, but the future use of the unit does not justify the expense.
The problem is, on startup, when engaging the shift levers (hi-lo, forward-reverse) sometimes, but not always, the lockup takes a very long time, once the hydraulics load everything is fine until you stop the engine. When restarted you might have to wait as much as 5 minutes before it seems to all of a sudden engage, and then your good to go again.
The atmosphere temperature seems to have no affect, oil level, or engine RPM, do not seem to help.
I'm sure that the inside parts are well worn, and in need of attention, I suspect most, that old shaft seals worn, or cracked, might be keeping a vacuum from letting the prime take place in the hydraulic portion, The pattern of this happening is so unpredictable, that it makes no sense if something is wrong in one area, why it would not act the same every time???:Banghead
It's a good thing the machine and I are old, and not often in a need to be in a hurry
Thanks in advance for any thoughts, I'll keep a list of any suggestions from anyone, until I find out just whats going on.
