Picking Out Replacement Grease Seal for # 174253TB

Question:

Replaced original seal tcm 174253tb with 1.741 bore with a National 473796 with a bore of 1.75. Noticed your Redline RG06-050 have a bore of 1.719. Question wouldnt it be better to go with the Redline since it is smaller bore then going up to the larger 1.75 bore? To be used on a 3500lb boat trailer. Thank you.

If the outer diameter of your spindle where the seal rides is 1.719 inches and the diameter on your hub is 2.565 the # RG06-050 would be the closest matching grease seal we offer. You will need a digital or dial caliper for this measurement like caliper # PTW80157.

The grease seal number you referenced doesn't cross reference with anything we offer but based on the bearing numbers a different customer came to us with that said they also had the same seal number you would need the # RG06-050. You would still need to measure to verify this. Your old seal you measured may have stretched over time.
