Here is the key to no leaks:
1. Bearings adjusted properly - no side or end play.
2. Good seal surface on the flange.
3. If you have to sleeve, this is approach to consider.
a. If you're replacing leather with a modern seal, you have to establish the new wear ring point for the modern seal. It will be a different location on the flange than the leather and if you use the old leather wear ring to gauge where you should install the sleeve, you may be off enough to actually hold the modern seal open with the sleeve causing a greater leak.
b. You determine the new wear ring by installing the modern seal. Apply a thin film of grease around the flange and install it. You don’t need to torque it down, just tighten it.
c. Untighten the flange nut and remove the flange. The grease will identify the new wear ring point by a ring rise of grease around the flange surface.
d. Measure from the end of the flange to the grease ring. Install the sleeve midway over the ring.
e. When installing the sleeve, the flange surface must be clean. As you drive the sleeve on, apply liquid steel around the current wear groove and work under the sleeve as you drive it on. You don’t want any air pockets. The purpose of the liquid steel is to seal the sleeve and prevent distortion of the sleeve by the oil seal causing the flange to leak again.
f. Once the liquid steel has cured, break away the sleeve flange carefully to prevent any distortion of the sleeve.
g. Lightly coat the sleeve surface with grease and install.
