My mahindra 2538 pto seal has a slight leak, I have the new seal and am wondering if i should use some type of gasket sealer on the gasket or not

I usually put a little oil or grease but mainly use whatever fluid it it restraining on the lip when installing seals.

I only grease both sides of gasket, and inside of seal.

Usually they don't leak unless the fluid in the gearbox is too high. It needs to be below the seal lip, or if the outboard bearing has excessive radial play.

the hyd fluid sightglass is higher than the pto seal , so i assume the fluid is also so not sure what you mean by fluid being to high ?

The sightglass is even with the top of the pto shaft The level fluid line is just above the shaft , So the lower 2/3 of the seal has fluid on it,

I usually go by how the original gasket was installed. If it had some form of sealant I use some on the replacement. If not install it without.
