Jake Kuhn 1,547 #1 Posted July 17, 2015 Hi all, Does anyone happen to know if lauson h55 parts interchange with Tecumseh h60? Picked up a 550 that had a motor in pieces and if there the same as h60 I want to go through it but otherwise not sure where I can find part? It does have a h60 shroud but I remember hearing when they have this indent in the block they are a lauson...also has the wico ignition setup so I'm guessing its a older one because my lawn ranger motors did not have this. Any help would be appreciated... Thanks,Jake Share this post Link to post Share on other sites

sorekiwi 761 #4 Posted July 18, 2015 (edited) I am very rusty on this, I am pleased that I havent worked on a Tecumseh for quite a few years!!The indent on the front cover is where the oil pump is housed. The H60 does not have an oil pump, so does not have this indent. The H55 does not have a dipper on the rod, the H60 has the dipper for its splash lubrication.I do remember that I used H60 rings in my H55, also H60 gaskets. I reused my H55 piston and rod. A few years after I freshened my engine, I came across a vertical shaft engine that had an identical oil pump and rod as my H55. I think the vert engine was a V55."Puddlejumper" was doing a bit with the H55's at one stage, you might find some info in his posts, or if he is still around he might remember more than I do. He ended up with a few of my left over pieces.EDIT: My mag looked different from that, but my engine had no charging system, so that may be the difference. My throttle/governor set-up looks the same as what you have. My '63 Ranger also had this setup on its H60.
