1862 engine swap question

[Tater305]

Not sure if this is the correct place for this if not sorry. But I have a 1862 I was looking into changing the M18 motor that is in it cause 1 I'm not a big fan of the kohler KT or Magnum and 2 the motor needs the oil seals fixed cause they leak, but mostly I dont trust the motor. But I have a flathead briggs stratton so my question is did cub ever make an adapter to bolt that motor the the driveshaft? or dose anybody have any idea on this subject? I am getting a 129 soon and if I get that up and running then I can work on the 1862 but until then I need it and about the time I take it apart we will get that elusive white stuff.

I got a 1861 and I love that engine. I didn't like the plastic, but, that is gone now.

I would fix the seals and run it. That is the best value for your $.

If you ever wanted to sell it, the conversion would drive the price to 10 cents per pound, because nobody trusts the upgrade.

Briggs V-Twin engines are common upgrades, so they hold their value.

Yea I understand you have the flathead, I'm just giving my 2 cents worth on what I have seen happen to tractor prices for machines that have been changed.

I would never try to sell the 1861, it is probably in the 10 cents category because of the hood swap.

First your M18 is a good motor. I would not replace it with a BS.
Where is your M18 Kohler leaking? If it is the front seal on the pto end of engine. You need to do two things. Replace front seal and reed valve under the valve cover. A bad reed valve builds up excessive internal pressure and oil blows our the front seal.

Fix your Mag. They are a good engine with lots o power.

I agree with fixing the Mag. They are a great engine. Much better than a briggs flat head in my opinion. but if you insist on using the briggs, you might look at checking with Patton Acres or Ray's IH parts for the driveline out of a 1641. The 1641 is the same style as your 1862 but uses a Briggs engine.

I, too, would encourage you to repair the M18, which is an excellent engine. The horizontally-opposed B&S is inferior to the M18 in several ways. I have had quite a few M18s, and one B&S flat twin...I had more trouble with the B&S than I did with all of those Kohlers combined. The Briggs is a cheaper engine, and it shows.

me and this M18 have a long history i actually sold him the motor cause I did nothing but fight with it. I got the motor back in 09 and just now got 3 hours on it after i had to fix it 4 or 5 times the first time the "lawn mower repair shop" said they fixed a busted rod and replaced it which was true but they forgot to remove the old rod pieces and one day the oil gear picked up the pieces and guess what no oil pressure(had a gauge on it) the other times the seals wouldn't stay in it so I sold it to the guy I bought the tractor from did the same thing to him and it sat then I got the whole tractor back with my old motor.....But anyway both the PTO and flywheel seals are leaking so they need new ones. I have just had more luck with briggs motors than kohlers....I plain on running the motor until it dies but its always nice to have a back up especially when you have 3 briggs motors sitting on the floor looking for homes..my crown jewel is the custom 20hp briggs in my pulling tractor but it stays there

After fixing my mag, Im really pleased with it. Its my second one I own. I love the sound in Dannys 482 with the command, but the mag builds more torqe than the command. Also, and this is JMHO that briggs is crap. 90% of the stuff I work on ever day is briggs, that is eng work. If your running Vanguards, that dont count, thats not a briggs eng. Briggs just bought the name years back from what I understand, those engs are great! Except for the coffee can load of bolts in the tin work! LOL

I would rebuild my mag if it were me. I have some extra parts here Ill give you REAL cheap if you need stuff. Also check with AJ as I have gotten a lot of help with my engs from him. The only thing I dont lie about the mag is that you have to grind the valve stems to set the lash. If you dont have the proper valve grinder and you grind them slightly off the valves wont spin, there for causing a good chance of carbon getting into the seat.

Tater,

I hope you are sucessful fixing the M18. But, if you want to let that 1862 go, I may be interested. I'd like to find a 1862 or 1864 to fix up for my son.

Thanks,

Ike
