Well I finally got all my ducks in a row and started putting this engine
back together. I would love to say it smooth as silk , but not. I was having a heck of a time getting crankshaft end play correct as when I would take the bearing plate off the bearing would always stay with the crank. Got that dealt with and then things went south. Could not get the bearing plate to torque down right. It just seemed odd the way it was tightening up. I did manage to get it to about 20 foot pounds and then snapped a bolt off in the head. Now I got big troubles. That seemed like a lot of torque on that aluminum plate. Never been real successful at removing broken bolts. Dang. Is it possible that the book has a misprint. It says a K181 needs 115 inch pounds and a K301 is 35 foot pounds. How can it be that different? Help Ken

I don't know if there is a misprint, but 35 ft/lbs equals 420 inch/lbs
To convert ft/lbs to inch/lbs multiply by 12: 35 X 12 = 420 115 inch/lbs equals 9.583 ft/lbs To convert inch/lbs to ft/lbs divide by 12: 115 divided by 12 =9.583

Those bearing plate bolts can end up yielding when you try to torque them down. One or two of mine did; would get to 20-some-odd foot pounds and would just keep stretching after that. I just replaced all four with some grade 8 bolts and they torqued down perfectly. 35 ft-lbs for the K241-K341. 115in-lbs for the K91-K181.
Easiest way to get the bolt out if you have some of it sticking out would probably be to weld a nut on. Sure felt like it was always one step forward, two steps back when I was rebuilding my K241, so I few your pain. But you’ll get there eventually, and it’ll feel pretty darn good once you do!

Just curious where you guys got your numbers.
I know this is probably too small to read in this post but it is a screen shot from the Kohler K Series Service Manual in this site's Tech Library. It says: K91 200 in. lbs K161,K181 15-20 ft. lbs. K241,k301,K321 25 -30 ft. lbs. K341 25-30 ft. lbs. https://www.onlycubcadets.net/forum/...ead.php?t=4646 Page 1.7 also, if you're lazy like me.... https://www.thecalculatorsite.com/co...oot-pounds.php Edit: When he said "I did manage to get it to about 20 foot pounds and then snapped a bolt off in the head. " I thought he meant he snapped a "head" bolt. Sorry for my confusion.

Thanks for the feedback guys. Yes It is bearing plate I am working on.
I am looking specifically at page 12-10 item 4 for where it lists 35 foot lbs. Where does it say 9lbs Lew? I did manage to get the broken bolt out today. Sigh of relief. Rusty got me thinking on the bolts not taking the torque so I went to further investigating. The threads closet to the head are pretty tore up from stressing em. Did some measuring and the 1.25 inch bolts that came out of are within a whisker of bottoming out inside the block. I think that is what was hanging me up once I put the heavier torque on them. Don't really want to go to a 1 inch bolt because that only leaves a 1/2 inch of thread in the block? I believe I will go get some grade 8's and try again, gently. Maybe double washer if it gets weird again. Thanks again Ken

Page 12.10 lists 35ft-lbs for the bearing plate bolts on a K241, as Ken said. As far as only 1/2” of thread engagement, that would more than likely be enough. General rule of thumb is 1 times the nominal screw diameter for steel holes, 2 for aluminum. Block is of course cast iron but I would think that ~1x nominal diameter engagement would be sufficient, especially since there isn’t a particularly large amount of thrust loading on that bearing/plate (or else they would have used tapered roller bearings instead of ball bearings  )Btw, the fasteners in question are indeed 3/8-16.

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.
