grenade gears!!
 

I am getting a plan together for one of the two cubs, just not sure which one, to get one running good for mowing season. With the limited knowledge I have so far I do know that these gears could be a problem if still inside an original engine. The question is, can I see if the gears are inside without tearing the engines apart? One is in a 109, looks original, the other is a 149, I know it is not original, but not sure what it is, the plate has been painted and can't read it. If the gears are out I will work on just getting them running and go from there, just don't want to air out a good block, or two.

If the engine has the dipstick on the front right then it does not have balance gears.

If the dipstick is on the cam gear cover next to the points, then it may or may not have the gears. In that case you would need to pull the oil pan to look for the gears.

Thanks for the quick reply, I am going down to throw a few logs in the stove so I will take a quick peak. Hears crossed fingers that I don't have any, I think the 10 is good, the 14 has a dipstick on the right, but something down by the points.

Well, the 109 has the dipstick on the right, yee haw. The 149 has a dipstick/ fill tube on the right in the same spot, but also has the dipstick down by the points. The engine is the wrong color and the paint looks like crap, head gasket is leaking so the 149 engine is coming out for a closer look. I really want the 149 for the main mower so time will tell how deep I go into the engine. Looks like all the way.

I bought a 147 with the same set up apparently the previous owner used a different block during rebuild ! my opinion for whatever its worth just from past years of experiance is if you leave the balance gears in then eventually youll end up having to tear it down & rebuild it anyway possibly with quite a bit more damage ! So i would go ahead & remove those things while yo got it out ! Ive seen to many blocks with extra air holes due to balance gears !

Thanks, I am going to take a look see. If there are gears in there, they will go away with probably a new rod. I hope the cyl is not bored to big to save.
