K341 engine questions
I've pulled the engine off the 1650 I recently purchased and found that only 3 of the 4 mounting bolts were in place. Upon further inspection, I found the 4th bolt sheared off in the oil pan. After extracting it, oil leaked (slowly) from the hole. Without having removed the pan yet, my guess is that a previous owner over-tightened the mounting bolt and broke through the bottom of the tapped hole. In the process, they broke the bolt. Since the ISO mounts were shot, it was easy to see this happening.
So here are my questions: 1) Does my scenario sound reasonable? 2) Can the oil pan be repaired (how)? 3) Are solid ISO mounts a good way to go as I rebuild? 4) Should I still modify (cross-brace) the engine cradle if I use solid mounts?

Hi MFP8055,
Instead of trying to repair the aluminum oil pan, I'd just replace it with a cast iron one. I did this on a 1250, I used to own. Also, I'd just buy the rubber ISO mounts from Cub Cadet. Unless, you prefer to use the solid ones. Please do the engine cradle upgrade, you won't regret it. My 1250 did great, after doing these repairs. Hope this helps! |

Ditto on the replacing the oil pan suggestion.
Another reason to replace the aluminum pan is your old pan mounting pads that mate to the engine rails are probably badly worn, point being even if you choose to repair the threads, the pan will not fit properly on the rails. |

I would modify the engine cradle if this was my Cub. My Dad has 2 cross braces in his 1450: This Cub works in a small truck patch. Solid vs. Rubber mounts: I'm not going to touch that one. One thing to remember is a 16 horse motor has the most weight rotating inside it. They will shake some.... |

Merk Your dad did a nice job on the cradle modification, the rear bracket may be some over kill. I'm guessing the reason he done it was because he welded the front bracket between the rails and did not overlap it.
When I do it I overlap the front metal bracket a inch or so over the rails and then you can do 4 welds on both sides of the bracket. When you do that a train couldn't pull it apart and you only need one bracket. Your dads looks good and should last forever too. |

I haven't had the chance to pull the pan off yet, so I'm not sure if it's cast iron or aluminum. Any thoughts on where to find a cast iron pan? I'll need gaskets too. The metal for the cradle modification has already been put aside, so I'll get to that shortly. What I found surprising was how soft the ISO mounts were. I just changed the body mounts in an older car I have this past winter, and I expected something similar on the 1650 engine. No surprise that they wear out. I may try the sway bar bushings as a compromise between spongy rubber and solid metal.

Unless someone changed it, it'll have an aluminum pan. Put a want ad in the classifieds, search on ebay, etc. to find a cast iron pan.
I would highly recommend the OEM mounts. They are expensive, but when installed properly are very smooth at full throttle. The new ones are harder and should last longer. |

I found a few cast iron pans, but they are quite different from what's on the K341 now. They are referred to as deep oil pans, and have square, flat bottoms. I'm sure they would bolt-up to the engine, but what about the ISO mounts? Do these pans work with the standard mounts, or do I need to make further modifications? Are cast pans identical to the original shallow plan out there somewhere?

Yes, the cast iron pan will look exactly like your aluminum pan, the square bottom pans are for other applications and unless you have a milling machine and are willing to do the work... Just trust me on this.

Thanks for the clarification. I'll keep looking for a cast iron pan, and take a look at repairing the aluminum original as a back-up plan.

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.
