Question:
Planning ahead for spring when I repack my bearings. Looking for lip seals and grease caps for a Terran axle. ST52N-C-S-80.5-65.25-US-6107-7112-E Customer refer.code: A009 I see Terran lip seals for everything but the 5.1K. Are you able to give the correct replacement part numbers?

Expert Reply:
Hey Peter! For your Terran 5.1K axle, you need the following replacement grease seal and caps:
-Terran Double Lip Grease Seal # TX92RJ
-Terran 2-1/2" Grease Cap # TX75RJ
The grease seals measure 2.250" ID x 3.376" OD, and the caps fit a 2-1/2" hub bore. If you decide to replace the bearings instead of just repacking them, I recommend the Bearing Kit # BK3-100. This includes the inner and outer bearings, races, and grease seal so you won't need to purchase the seals separately.
