C153 engine

[rusty504]

Thinking of "rescuing" a C153 engine from a draper windrower going to scrap. It was supposed to be low hours, but it has sat outside for 35 years and is stuck. What would be the minimum for consideration to make it a usable runner again after getting it loose? Should I be thinking new rings and crankshaft bearings? What about cylinder walls cleanup? I have read that these weren't great engines, but maybe it would find a use somewhere, such as on a generator. Thanks!

Remove the spark plugs and look inside as best you can
a snake cam would be helpful

if the exhaust was open to the rain
could be most anything 

Else get some PB, Kroil, or FreeAll and let it soak over several days
Diesel and automatic trans oil also works but slower

I would tend to treat this as an out of frame overhaul.  You might need oversize pistons depending on the how much corrosion is on the cylinder walls.  Or sleeve it down to a 135 (a short search says both use the same block and the 153 was sleeveless).

1 st what are you doing with it??

As it is simply a max bore 135  /likewise it can have up to 7 bolt/ bell housing acc patterns.

check casting # sizes etc 6 x  ?

Unfortunately they go to scrap as PC says parts are illegal. Expect $1000 + if its not super NLA late #. But/with salt $12K new engines dont make it 1000hr.

even last years off the shelf "custom sleeve ($20)" is NLA Bob retired or $500+

When a $.03 (retail)many use) line seal (5-10yr life)2x change)can only be purchased in 1000+ ,forcing stealer into faux NLA for $3+ ea + $20/ship,and open market is $20-50 /ea + $20 = $2 stamp shipping. Few will buy it thus the " faux crisis whine"  "no one bought any last year"

Thanks for the replies! I haven't looked at the engine much yet. I just hate to see an engine be scrapped if there might be any possible use for it. The rest of the machine is obviously far outdated and would be a difficult restoration if someone even wanted to. I know this was an odd (sleeveless) engine for IH, so I won't put much time into it. It was a low acreage machine, but nature can do nasty things.

Is that the same engine as in a 504?

Yes, and no. It's the same internals, but this version of the engine will fit tractors like the Super C. You need to make accommodations for the pilot bushing in the flywheel, and there's one bolt hole missing, but if I'm not mistaken the swather C153 will otherwise bolt up, giving you a "Super" Super C.

So would it work in my U123?

I'm looking for a replacement engine for my U123. I think it's got a super C engine but I'm not sure.
