The manuals seem to only give an example of installing the pulley side crank seal when the case is split.... Whats the procedure when you dont feel like splitting the case? I would imagine prying it out is simple enough but the install, just pound it in dry with an appropriate tool? (I swear no puns intended)

It's just a seal and goes in like any other. after removing the old seal make sure the shaft and hole are clean and the shaft is smooth. You may want to remove the key from the shaft. Don't do it dry. Use some assembly lube or engine oil. Slide it on making sure the lip isn't flipped back and the spring doesn't fall off.

Gotcha. O.D. oiled as well? Thats what I was asking about installing dry

Rob Edwards

Yep, OD and ID oiled.

To ensure it ends up being square, you can make a pressing tool, as shown here (post #3):

Post #28 in the thread below lists Greg Brown's procedure for prepping and installing the rear main seal, I assume it applies to front crank seals as well:

From SKF
Seal installation, general industrial applications
To provide effective sealing, radial shaft seals must be installed properly. An experienced installer with suitable tools, working in a clean environment, is recommended to provide proper installation. The shaft counterface surface and housing bore should meet the demands specified in the sections Shaft requirements and Housing bore requirements.
To facilitate seal installation and to achieve initial lubrication, prior to installation, SKF recommends wiping the shaft and seal with the lubricant that is going to be retained. While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated.
Seals with an auxiliary, contacting lip can also be filled with grease between the sealing lip and auxiliary lip to reduce frictional moment. This does not apply to silicone rubber seals and seals with hydrodynamic features, other than SKF WAVE lip designs.
SKF also recommends using a hydraulic press, with suitable tools, to install a seal in its housing bore. Pressure should be applied as close as possible to the outside diameter of the seal.
Seals that are designed to sit flush with the wall of the housing bore must be installed perpendicular to the housing bore axis. The outside diameter of the tool should be larger than the housing bore diameter (fig 1).

Is the main seal not a silicon rubber type? I thought it was...in that case its no oil on OD

Thank you MrMerlin
