I am restoring a Red Wing Thorobred 4 HP with a Paragon Reversing Gear. The Red Wing is almost complete but I am unsure about re-assembling the Paragon (probably both early 1920's). The gear housing with the planetary gear system is stamped with GREASE but I think this would be too heavy a lubricant. I am more inclined to use either standard transmission oil or differential oil. What advice do you have? Does that also apply to the three brass clutch plates?  |

The GREASE probably refers to the reversing band since it is steel on cast iron. The body of the transmission is turning at engine speed inside that reversing band.
For internal lubrication, I use 30 weight non-detergent engine oil. Differential oil is a lot heavier and might cause the transmission to drag in neutral.
In a boat that wouldn't be good; at a Show, it's OK.
There aren't shaft seals on my transmission, so the whole thing probably drips a little oil.
It looks like you've done a really nice job on the restoration. What's the history of the engine?

Miro, thanks very much for the response and advice. I picked up the engine and paragon reversing gear assembly as a unit in a garage sale several years ago for $100. It sat in the garage until this year when I decided to restore it. The Red Wing engine is a single cylinder, 4-cylcle engine of 4 HP and has a serial number 6154K. I assume it is circa 1925. I completely disassembled the engine and it showed virtually no wear, and all journals were tight. I grit blasted and painted all the cast parts in grey which appears to be the original colour. The copper and brass cleaned up with polishing. |

I'm now in the process of restoring transmission that looks just like this one, only it has two screws, the one over the friction plate I don't no what it is there for ? does the friction plate also get oil ? Had to make new friction plate, original had stress cracks. I will try to post pictures.} |

These old exposed reverse gears lived very well with almost no lubrication other than what ever was used when it was assembled. The assumption was that the entire clutch and gears rotated as one big lump between the engine and the prop shaft when in forward since none of the internals was doing anything with the clutch locked. It was also assumed it would spend most of its time in forward.
Not true for the rear main/thrust bearing though. Most of these had a grease cup right on the bearing since in most cases it took all of the thrust from the prop.
