4X4 not always engaging

[TomB1550]

Hi Everyone, I own a B1550 4x4 bi-speed. I only purchased it a few months ago so the first thing I did was to change all fluids and filters. When I drained the front diff I only got out 1/2 a litre yet the manual is clear that a bi-speed should have 2.5 litres and no bi-speed 1/2 litre. I hadn't noticed any issues before but I hadn't really been looking so once I completed the job I took it out on the ice/snow and proceeded to get to spin.
Heres what it does:
Sometimes the back will spin and the front just sits there, if I push in the clutch and let it out the front will then spin too. I can drive it around for a few minutes then get it stuck again and have to push the clutch in again to get the front to engage.

...any thoughts......hope its not because of last owners mistake

There is a set of clutches in there, and I bet that when it was run low on fluid it damaged the clutches or assembly.

Thanks very much, I don't have a service manual but I'll drop by my Kubota Dealer today and see if I can find a little more information on the clutch assembly.

I went by the dealer, but to no avail, the mechanic simply said he wasn't sure. He could take it apart and figure it out for about 3 hours labor. I told him I would keep investigating on my own. I'm thinking next step is a service manual.
