Hi Oscar; I can see how you ended up here since a search for the MTP 5103 pulls up our CE Smith Grease Seals # CE16305A. However, I don't see anything that corresponds with the MTP 5103. I also wasn't able to find measurements using that part number so I can't confirm these are the right replacement.
The best thing to do is take a digital caliper # PTW80157 and measure the inside and outside diameter of your current seal. If your inner diameter is 1.00" and outer diameter is 1.78 " the # CE16305A will fit. If you have different measurements please add them in the comments below and I will see if we have a replacement that matches.

MPT seal 5103 I was looking for the same seal as it’s on a towable log splitter that I’m servicing. The old seal measured: 28.44 mm ID 45.2 mm OD 10.5 mm wide None of the auto parts stores could help me and I ended up sourcing it form EBay. Now you have the numbers. Steve

Hi Oscar, did you get a chance to measure your old seal with the digital caliper? Once you had those inner and outer diameters, were you able to confirm if the CE Smith grease seals were the right fit? Your update could make it easier for the next person trying to match that MTP 5103 part.
