Would a NOS power head gasket kit include a crankshaft seal? Sure hope so

None of the power head gasket kits I’ve ordered have included the crankshaft oil seal. Some kits may include the upper and lower case O-rings. Depending on the individual motor, the gasket kit may or may not include the cylinder head gasket.

Thanks for the reply. I’m now working on a Scott Atwater 5 hp with low compression. I’ve got it torn apart and everything looks really good , cylinders and pistons not scored and the engine looks very clean over all but noticed a lot of gummy oil under the cowling top and bottom. Was thinking maybe a crank seal might help with compression but probably kinda like winning the lottery to find one lol. Anyway got it tore down and gonna paint it and put new decals on and shine it all up good and make a “wall hanger out of it I reckonMay 27, 2019 at 7:26 am #176095
I replaced the top and bottom crank seals in my Scott 5hp with easy-to-find stock seals from a local bearing supply company. I dunno, I may have written the numbers down.—-Maybe.May 27, 2019 at 7:36 am #176096
Yeah, here ya go—
Top seal: OEM#497-1910. TCM# 087111VM-BX. 7/8″ x 1-3/16″ x 3/16″
Bottom seals (takes 2):OEM#497-1915. TCM# 07101VC-BX. 3/4″ x 1″ x 1/8″.
I think this was a 1954 motor.May 27, 2019 at 8:49 am #176099
Mine is a 1949 model. But your saying get the old ones out , take to a shop that deals in bearings/ seals and maybe they can get a replacement?

Thanks I’ll try thisMay 27, 2019 at 2:56 pm #176132
A little lesson in Scott part numbers: The first section of the number is the motor model number where the part was first used. The second section (after the dash) identifies the particular part. So, taking the number I gave you for the upper seal, 497 is the model of the motor where it was first used (model 497). It so happens that is a 1949 5hp. 1910 says it is an upper crankshaft seal.
Summing up, the numbers I gave you should be good for your 1949 5hp.
