No wonder I don't have hydraulic pressure, Oliver 88

IFF · Sep 30, 2016

I posted a couple of weeks ago that I had zero pressure from my Oliver 88 Group 1 hydraulic system. I took out the pump tonight and found the centerplate, which I had replaced, is too tall. It stands ~1/4" proud of the gears. The centerplate is 1 3/8" thick and the gears 1 1/8". I know there are two different centerplates and I must have the wrong one. I feel foolish for not catching it the first time around. I think at this point I am going to adapt an external pump to the tractor, hiding it the best I can.

I think you have the correct center plate, but you have the wrong gears. Sounds like you may have gears from a 66 series.

The very early 77 and 88s used an 1 3/8 inch centerplate. They also used a 16 tooth gear with a different shape. All the newer used and 1 1/8 plate. The 66 plates were 3/4 ".

I have said the same a few times,I don't anymore. It ain't fixed till the fat pump sings.
