Trailer Grease Seal 34823 has a Larger Diameter than Seal 12194

Question:

hello, I did purchased a bearing kit, the bearing part # 44643 and seal #34823. I will using it in a reliable sure lube system, everything looks ok. but the seals are a bit different being the old seal taller than the new one, my question is if the new seal will fit in my application or I need to buy the right seal.

If by taller you mean that the seal has a larger outer diameter then you would not be able to use it. If you mean that it is deeper then it is likely not a problem but you would know if it does not sit flush with the hub once the seal is installed.

From what I could find the 12194 seal that you have has an outer diameter 0.004 inches less than seal # 34823. The difference of 0.004 inches is very minimal but you will still need to use caution when installing. I recommend using a piece of wood and tapping gently until the seal is seated in place.
