Just a pump that you operated once and a while to lube the rod as it zipped past |

Here is a pic on one on a 3HP
You open the valve that is horizontal and then operated the pump handle that is verticle. When finished you closed the valve. There wasn't really any nozzle inside just a small pipe that kind of headed at the rod.

Unfortunaly I didn't get the lathrop running yet . I was in the process right before huricane sandy completely destroyed my automotive business . The engine went under water , but I drain it and clean it up . Engine survived but I lost 80 % of my equipment , tools and cars were gone . I will post some pics and I am glad you responded . I am sorry it took so long as I was and have been recoving since . |

Thank you Richard for posting the pics .
Hello everyone , I have many questions about this Lathrop Engine and need help . I have looked into a lot of reading material and specs posted here . Some information I can't seem to locate ? or understand at this time . Thank you all in advance
Any one seen a fuel mixer like this ? The only information stamped on it stated " Gen Valve Co. NY "
Is this for fuel ?
Can I get a seal kit ? |

Scott , I see a pin , contact arm , cup washers , spring , cam , upper rod bracket ,
and to the left looks like an adjustable threaded rod . Are these parts availible along with a make and break ignition system ? Recently I ordered 2 books from stan grayson , so I can learn and research the correct terminolgy of these parts . My goal is to complete this project and bring it to the mystic sea port show next year . |

I don't know of a source for these parts you will probably have to hand make them if you come to the seaport I can show you what you need. |

Thanks for the reply post on B&W engine..
Pulled Engine out.
Block no, G5288IHENY
Head no.505986
Found timing marks on crank sprocket, block and cam sprocket. I assume they all line up toward each other, to put chain on but would like to know for sure.
Do you know any websites for nut and bolt torque settings.. |

Keep in mind Old Man Lathrop didn't believe in mixing oil in the fuel to lubricate two stroke engines. His customers certainly did and those stupid pump lubricators were his answer to the long argument about how to lube two strokes. Put some oil in them and don't use them mix the oil in the fuel and you will have no lube problems with piston and lower bits in my recommendation. |

Hello All,
The operators manual I have from 1931 says the pump on the side of the crankcase is only used when starting the engine. Open the horizontal valve handle 2 turns and pump the plunger to prelube the big end of the connecting rod. The rod has a felt held in place under a perforated steel deflector. This is screwed into the web of the rod. The felt drips oil into a well in the top of the rod bearing boss. I'll take some pictures of this next time I have the side cover off of mine. I can assure you, if you open that valve with the engine running the plunger on the pump will not be able to be pushed down because of crankcase pressure. At least I think that's what happens. I was wiping the oil that used to be in the oiler out of my eyes.
There are double oilers on all of the Lathrops in my catalogues and pictures. These are piped to the cylinder wall and to a disk on the crank that lubricates the big end of the rod when running. very similar to the early Gray arrangement. It is my belief that along with not mixing oil and gasoline, Mr. Lathrop was a proponent of running on kerosene. The kerosene injectors are ported right into the cylinder from the intake port therefore no gasoline and oil is used when running on kerosene. This will require an external oiling source; the drip or force lubricators. Again, the plunger pump is only used for starting. Maybe this helps, but hopefully it excited more questions...
