The original subject was Re: KT, KTA, early U Moline.

Hello,
I just read an old post from you from I think 2011.
I'm contemplating a purchase of a 1938 Twin City KTA.
The owner said it hasn't run for maybe 3 years. As far as I know it has been parked inside.
My question is, should I try cranking it to see what it feels like?
Or is this not wise because I could bend a push rod or something else?
It is a very complete tractor and I'm very interested in it. But of coarse if it is loose or not, this makes a difference in the long term work and cost to get it running.
Any advice for me?
 
yes crank by hand slowly. if you feel resistance not normal stop. the best thing to always do when a tractor has been sitting is remove the plugs and squirt at least one once of oil in each cyl. that at least lubes the cyl's. and as i say turn easy as a stuck valve will give resistance with the push rod,... keep turning and it will bend the push rod. just use sense. dont force it.
 
KT,KTA motor not same as early U. Motor is a KEA and has no starter so has to be hand cranked. As long as motor not stuck should be good.
 
Good advice already.
Without actually saying it, a couple guys might be alluding to checking the valves to see if they're not stuck and they're right.
Great starting point. If an engine is up north or in a humid climate, inside a shed or outdoors, the moisture gets to to the parts in a short time.
Crank gently until you know. If it's freezing outside be more careful, might be moisture in the oil pump.
Found the link Tom is talking about: I've been looking for this parts book info also. :)

Neat topic Tom! Thanks for bringing it up.
Yep, GB is talking about the engine models. :) The KE casting numbers shows up on my 1950 UTS with one 10A and one GE head.
Doggone it, I don't have a good pic of the engine tag.
Darn it, not an engine tag pic of the '30 KT engine out here either.
Reminds me: I need to talk to Charlie...
Keep us updated.

KEA motor from 1929-38. Replaced by KEC in U and KED in UDLX. KEC 38-41. KEF 1941-47. KEF had precision bearings. Earlier babbitt.
 
Does anyone have a good motor drawing of the KEA (for the KTA tractor). Maybe with some cut away views? Or whole tractor drawing showing internals of gearing and motor, etc.

Thanks in advance.
 
Not sure if there is one on manual. Basics same as U. Rods, pistons, block, head and valve train all same. Crank,crankcase,mains,etc not. KTA has different mag mounting,waterpump,flywheel. Not sure what you are looking for?
 
Is something like this what you're looking for? From the Kombination R739F parts book.

You're welcome. Only takes a few minutes to help. You helped me with that link above so... :)
There are a few more images I'd share if you need them. Like GB asks, whatcha need?
If you buy that late KT-A, I'd also suggest the two or three manuals at the manual store. Sshhh, they're generally cheaper than jen.
No affiliation but that's my go-to source for manuals.
We'd like a serial number if you would.
Note; the service manuals are usually the old Instruction books.
Trouble is we usually can't see inside to see which specific manual it is until we get it. That's often inside the front cover.
IF you go this route, there are two KT categories: KT and Kombination. 79909 and 79625 are Instruction books.
Oops, 79625 is an operators manual. Same as 79909?
79791 is the parts book. Makes me want the 79909 book as the cover says Twin City KT just to see if different.
The image I took is from 79791 from that store. As it says Kombination.
I've spent too much time inside TC manuals. :) I type too much.

The engine drawing is great.
Do you happen to know what spark plugs
were used?
The drawing answered a question relating
to the two front axle stabilizer bars. I
see they are tied back to the oil pan.
Obviously the pan is cast iron and beefy
enough to handle that function.
If you have a drawing showing the tranny
and brakes that would be helpful. I'm
guessing they are band style brakes?
 
I have the w89 Champions in KTA same as in 12-20. They are obsolete. 39 UTS Waterloo belted to 38 KTA

Say it isn't so GB. The champ W89D/W89 is done for too?
Stuck with the Auto 3076? That all we have left to choose from?
Neat picture of a brother turning an older brother by the way!
