"Flex Coupler Arms Fastened TogetherWith solid motor mounts installed in a Cub Cadet that originally came with an ISO-mounted engine, the driveshaft will not be able to "move" with the engine and there'll be less chance of clutch parts prematurely wearing or breaking. The flexible rubber disc(s) at the end of the driveshaft will be useless too, and could deteriorate over time. So instead of replacing the OEM coupler arms with a machined rigid tubular coupler, make the coupler arms rigid by removing the flexible rubber disc(s) and install a couple of 3/8" thickness spacers for a single disc, and a couple of 3/4" thickness spacers for double discs, and then fasten the arms together with a couple of 3/8" diameter hardened steel bolts. (Large nuts are used as spacers in the picture to the right.) By the way - one rubber flex disc is 3/8" thick. This setup is just as strong as using a rigid tubular coupler, and it cost a lot less." Anyone have any other opinions on this? Im all ears |

I understand why now. His name, nor link is mentioned.
Not trying to cause problems, just seeking advice I would like opinions on mounting the rear flange from experienced person's. |

No harm in keeping the flex disc connection, regardless of how the motor is mounted. Having a flex disc in the drive line provides some forgiveness in alignment and should reduce vibration and stress on bearings, etc.

I am assuming you are still using the original rear coupler that goes on the transmission input shaft, correct? So if that is the case, then it has the centering bearing. So as long as that centering bearing is not shot or worn out, it should center your driveshaft with the center of your transmission input shaft regardless of whether there is a ball in there or not.
With that being said, I personally would NOT replace the rubber flex coupler with metal spacers because there is no way on God's Green Earth that you can tell if there is a direct straight line all the way through the crankshaft and through the transmission input shaft. Making it solid is an invitation for disaster unless it was originally engineered that way such as the older Cubs. However if it were me, I WOULD use TWO rubber flex couplers instead of one. Just make sure the end of your driveshaft is getting into the the centering bearing in the rear coupler. Just my |

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.
