Question:
I have a master tow dolly. Model 80THD. I need the brake drum/bearing assemblies. Not having much luck with Master Tow. Do you have a replacement for them?

Hey Steven! I don't have any specific information on parts for that tow dolly, and I wasn't able to find a parts list. However, it does look like it uses standard hub and drum assemblies. Is your current hub marked Dexter 8-247? In one picture I found it looked like that was the hub it had on it.
If that is correct, you can use the Dexter # 84546UC3 or if you want a pre-greased option our own # AKHD-545-35-EZ-K. These are designed to fit a #84 spindle with # L68149 inner and # L44649 outer bearings. If you aren't able to identify anything on the hub you will need to pull the hub and identify the bearing combination to be sure. Part numbers are probably stamped into the bearings. If not, you need to measure the inner diameter with a digital caliper # PTW80157.
If you find that you have different bearings or a different hub please reply below and I'll see what we have available.

Hey Steven, were you able to confirm whether your tow dolly hubs were marked Dexter 8-247 or had the same bearing sizes listed? Knowing what you found could help others trying to match parts for their Master Tow dollies.
