JD 40 hydrolics leak

[Tim Dean]

I have a model 40 tractor that the hydrolics leak fluid from the quadrant onto the brake housing. I have seen several other 40 tractors with the same problem, so I assume that this is a common problem. Does anyone know what normally causes this problem and how difficult is it to fix it? Thank you for any and all advice.

there are cork seals around the shaft that leak very common not to bad to replace it would help to have a manual or parts book to see the parts involved, the front shaft seal is the easiest to replace just remove the levers and braket first before removing the main body around the shaft when removing the main body from around shaft hold shaft in place and slide the body housing off there is is a litte snap ring on the first shaft that you take off a then you can slide the spacer and old seal off and put a new one back on if the shaft slides out during this install it will come out of splines in side then you need to take unit apart , the rear seal is a harder seal to replace, the only way I know is to take the unit apart
