Flywheel Removal
I'm in the process of tearing apart a k241 and when I went to remove the flywheel I noticed the flywheel key broke and the flywheel is rotated like 45 degrees. I put a puller on there and tightened it down and cannot seem to get the flywheel off. I tried the tap tap tap tighten method without success. Is there any tips you guys can give me to help get the flywheel off?

a very old trick.....Heat the hub with a heat gun or little propane torch and while it is hot run a household candle around the shaft so the melted wax seeps down between the shaft and flywheel, let it cool for about 10 minutes, then try again to remove the flywheel...sometimes this work, sometimes it don't...

Old mechanics know some kick butt things, things that keep getting passed on and on. Apparently only to a few select individuals.

flywheel removal
I worked on getting a flywheel loose on a K321 for the better part of two weeks. I sprayed penetrating oil on it, heated it, bent one puller and started on another and it finally broke loose. There is no secret formula that I know of, I used the entire vocabulary on it, and it finally just gave up and gave in.

I was actually looking at prices for pullers yesterday, they aren't bad and ill probably pick one up this weekend. I made my own puller with a 2x4 and a half inch bolt with a nut on the backside. It worked well on the starter generator pulley but im hesitant to use an impact gun on it for the flywheel.

I got a harmonic balance puller tonight, put it on and tightened it down and one smack of the hammer and the flywheel came right off. I think the 2x4 might have been absorbing too much of the energy from hitting it because I'm pretty sure I had it just as tight and it didn't budge.
I pulled the bearing plate and the crank came with it as expected. I plan on using muriatic acid to dissolve any aluminum on the crank so I can measure it properly. Is there any reason I should separate the bearing plate from the crank before I use the acid? Thanks for the help guys.

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.
