Is this the brand name of your motor as they use 2 different manufacturers. The Thompson Saginaw style was used around 2010-2012. This manufacturer has a thru the frame bolt that you turn. Think it’s a 5/8” nut
This is from the other manufacturer with the Lippert name on it and the nut is not a thru the frame nut but on the face of the gear box. Why I have both you donít even want to know at this point but if you need a new motor and yours is the Saginaw itís not made anymore and we need to talk.
