Default Quietline 12 HP into a 122??

Can I put a non starter generator motor into a 122? Got the old one from my 1250 parts tractor and the 122 is just sitting there begging for a motor...I do have the old motor from the 122 with its starter generator, no carb and only about half the tin....Will I need to swap short blocks or can I just plop the newer one in there minus cradle of course..and wire it up??

Entered the 1450 in a real pull today and I can definitely feel the need for a standard tranny /clutch setup.. That hydro is TRICKY to get in the power band. It didn't help that it was running against everything 14-20 HP either..the 12 HP class would be a lot more appropriate for my funds, so I'd like to get the 122 going by next weekend if possible.

Definitely not a bolt-in...Wiring harness is different, bearing plate is different, the starter will interfere with the frame, to name a few problems. You'll need to change the bearing plate, flywheel, etc. to put that engine in a narrowframe.

You could also notch the frame for the larger bearing plate. I have two 122 tractors that I have notched and installed 16HP engines. Brian Millers web site has the info on notching the frame.

Thanks guys.. I did a google and came up with the same thing myself. Can't notch the frame, it would be a dead giveaway there is something different in the engine department, so I guess it is time to get dirty!

Hi truckntran,

I'm a little jambed up for time right now but here's what I can tell you quick. Like Matt said, on the flywheel side of the 1250 motor take everything off up to and including the bearing plate then put all of theose same parts back on from your 122 motor. Then take everything off of the crankshft side and put your starter pully on from the 122 motor, the tricky part is that the 1250 motor may or may not be drilled for your s/g bracket, if it isn't you may have to build a bracket that will work, not sure without looking but you may be able to drill your 122 frame rail and bolt your s/g bracket there and get a longer belt, not sure if the belt will clear the frame or not, the s/g may need to be elevated to get the belt on. that should be about all except for adapting the choke and throttle cables and the exhaust is also a little different.

Good luck with getting it done for the weekend.

Hello from a new member in Mi. The swap of 301aqs into 310a spot requires the replacement of everything from the bearing plate out (bearing plate, flywheel,screen and blower housing) in order for the swap to fit into the narrow frame. As for the starter/generator, the bracket will bolt right up to the mounting holes for the later model starter. Remove the electric PTO and replace with the PTO setup off the 122 motor and the original start/gen belt will work fine. At least it did for me! I also did the reverse in my 169 to try to get it to start better in the cold Mi. winters.

I'm about halfway thru the swap and so far it has been a piece of cake. I found out my replacement engine had been taken out of a green tractor at one point, and everything on it has come off easily. Same for the original engine from the 122, PTO pulley slid off like it was greased, flywheel popped off easy too. As long as I am this far into the motor I am going to decarbon and clean up the valves... new head gasket and about an hour of assembly and I should have a good motor after that.



I hope!

Well, it is in, awaiting some wiring details to run. What I found out..

The original block was from a John deere...I do not know if it would be different than a Cub block from a quiet line but there was one serious difference in this particular engine.

The output side of the engine had a stepped ring that probably was used to center an electric clutch in the Deere application. It got in the way of the starter -generator arm. A quick grind of the offending part cured that.

The output shaft is about 1/2 inch too long. I cannot install the clutch for the mower without cutting off some of the extra shaft.. Otherwise the clutch fingers do not go into the starter pulley basket. Also there is not enough room for the clutch button with the extra shaft in the way. RIght now I was getting the tractor ready for a pulling meet, so it isn't gonna get dealt with for now. Maybe I should have installed the entire crankshaft...

THe other side of the engine fits fine, I had a low boss head 14 I stole head studs from and barely had enough room to mount my gas tank bracket on them...the right studs would have been helpful on my high boss head. I also was amazed how much carbon was in this engine, but there was virtually no wear otherwise. Valve adjustment was almost dead on already, and the guides were pretty tight for the age of the motor. The ports are really ugly, I can see how a little work there would really help out a hi perf rebuild.

I did find a NAPA number for a metal backed crank seal on teh PTO end.. SKF 15041 seems to work well...the original was cocked and fell into the crankcase when I tried to straighten them..pulling the seal was fun.

Got to go look up the wiring diagram for a 122 now.. and get this thing running!

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
