Hydramatics never work the first time they are back together.

That there is just plain ugly.

No? What do they tend to do?

I'm guessing airlocks in the hydraulics, adjustment issues?


Phil

Nah, they do some bizarre stuff. Then you take them apart once more, don't find anything wrong, put them back together and suddenly they work for some odd reason.

[PhilA]

Fair enough. I can see that happening due to the design of the valve block.

From an engineering standpoint, this strikes me as slightly strange. The two gear sets there are held together in that formation on the same shaft on splines.

Why would they be placed in an offset fashion? I would have thought they'd be perfectly corn-cob to distribute the load evenly. As they are, they're not quite corn-cob.

To avoid jerky shifting.

I was going to guess harmonics, but JM is more likely to be right.

Would appear it is by design

I need to make a contraption to press the clutch spring plate down so I can pull the snap ring and remove the clutch cone and replace the seal.

Hopefully I'll get the spares ordered tomorrow.
