luck!!

The M-18 had 170 different Spec Numbers, thus 170 versions of that model.

And I believe that all 170 use the same seal, but I have not taken the time to check each speck number individually.

I put a 52-032-10-S from Mowtown for $7.05 in my Mag 18 / Spec 24506 and don't have any problems yet.

I found the TN of the place I bought the longblock from. I'm going to call and get their take on the gasket. I recall something about it taking a while to deliver it to me because Kohler kept sending him the wrong gaskets (seal).

Cross your fingers. Like most times this tractor acts up I got disgusted and shoved it into the corner for a while. I had to get some other projects addressed. I checked with the rebuilder and got some pointers on this job and the part# he used. I went to a great local small engine parts place with that and got 2 seals. I pulled the engine out and the seal was shredded. It was the smaller seal and mine uses the larger. Not sure why I didn't catch that the 1st time. Must have just been rushing. Anyway it was obvious as soon as I set them side by side. New seal has been installed. Tomorrow I install a new fuel pump and put the engine back in. Hopefully everything will settle down for a while. It would be nice to just use this tractor for a season without a bunch of fussing with stuff for a change. It's a working beast and I really like it but it sure has tried my patience!

To install the seal I used a PVC conduit union/coupling that I found in the parking lot at work on one of my walks. Seemed like the right size. It was very close. I set the seal in place and added the PVC and then used the flywheel bolt with a large fender washer as a seal press. I went around the seal with a drift and it needed just a couple of very light taps to make sure it wasn't crooked. I try to get some pics up soon.

The saga continues. Pretty much had everything back together when I figured out where the gas smell we've been smelling in the garage came from. We thought it might have been from the pan of oil sitting under the tractor. IE still leaking fuel pump. It wasn't that. I've got a small hole in my gas tank!

Back in early march we had a pretty vicious storm here. Took down the power lines at the end of our lane on the main road. Trees came down on the lines and broke some poles. Lines set the asphalt of the road on fire! Needless to say we were out of power for a few days. No prob we have a wood stove, generator, and transfer switch. Just set up to run the needed stuff off the gen. I stick the power cable through a small window in the back under the deck from switch to gen. Went to put fuel in my portable 6k watt gen and it started flowing all over. The dang poly tank had cracked open! Well I got that all cleaned up and realized the tank from the Cub was outside as I was working on this issue. Both use 1/4" lines so I grabbed some fuel line and set the cub tank on a ledge above and a few feet away from the gen and hooked up 6' of fuel line filter of the Cub tank to filter of the gen. It worked great for several days. After I put the gen away I just left the tank on the terrace under the deck out of the weather. I have since added a Johnson outboard quick connect to the generator so I can just use one of my 6 gal outboard gas tanks with it.

Well it seems some small critter tried to chew into the fuel tank. May have broke all the way through or maybe almost so. It must have opened up when I put it in the tractor. It's kind of a squeeze getting the tank in the metal frame sometimes. Well it now has a small steady leaking hole. Just enough for a continuous drip. I drained the fuel into a can and now need to locate a replacement tank. Fortunately the old MTD started right up yesterday so I'll be mowing with that the next week or so. Nice to have a backup.

I also replaced the fuel pump before I reinstalled the engine today. I had a new in box spare that's been on the shelf. One of the new style ones. The Kohler engineer that designed that must have gotten his degree in "LEGO's"! It's one of the new plastic style with the snap in connectors and you have to use a big supplied snap ring as a keeper to hold the buttons in while you snap the LEGO pieces together. What was wrong with conventional, easy to source screw in fuel fittings? Once again a company found something that worked well for decades so they fixed it!!

I found a NOS tank on E*** today and bought it quite reasonable. It has already been shipped. I picked up the bushing and a new fuel shutoff valve at the dealer and should be good to go real soon. I hope anyway! FYI these tanks are now NLA from Cub/MTD.

Some pics to add to the story.
The too small trashed seal.

I should have caught this when I installed the 1st seal. This is what happens when you rush on service work and repairs.
Correct seal on left. Incorrect seal on right.

Home made seal installer. A PVC conduit coupler I found in the parking lot at work on my morning break/walk. a big washer and the flywheel bolt. It worked great. I just used a small drift punch to make sure it was perfectly straight when I finished up.

The seal worked fine for over 3 hours running last weekend.


Here is the NOS replacement tank, bushing, shut off valve.

Sweet seal installer. Finding it was luck or a testament of how much these cubs are on our minds during the day. I vote luck!:biggrin2: Congrats on geting it fixed and that NOS tank looks so nice!
