Overhauling a L235 DT 4wd...and similar (245?, 275?)

Got a few questions based on what I found below quote on another site. Beside though; thought it might be helpfull to someone else....

The L245 could be retrofitted with any of the following Kubota engines
D1100
D1101
D1102 (or any DH models of these where the "H" indicates a higher speed
version.)
D1300
D1301
D1302
D1400
D1401
D1402
D1462 (rare model)
The " A" suffix indicates originally manufactured for agricultural use.

These are basically the same family of engines.
The block drillings are all the same and whilst the bore sise changes,
the engines are interchangable without major rework.There may be
differences in sumps,manifolds,flywheels etc
but you should have all these parts with the original tractor that could
be changed over.

Also, the similar series engines from Daedong (Kioti)
engines will fit i.e TD1100, TD1300, TD1400
We recently supplied a TD 1400 Daedong to fit a Kubota L2002DT which has
the D1300 engine, and the conversion worked really well

With that info.... when trying to get an overhaul engine kit or any engine parts (no one shows any parts for D1102 engine) what should I be looking for... D1302 or 1402 orrr? to rebuild my 1102 engine.

To rebuild a 1102 you need 1102 parts as other engines while still in series will have different parts.

Wolfman you must have Orange Blood LOL! You seem to be the most common person answering questions in here.. I thank you for your time and assistance!!!!

Now back to rebuild kits... Drat; no one sells a rebuild kit for the 1102 engine. Means no discount for a "kit" compared to every part ordered individuallly. grrrrrr

But...... from other reading it appears the 1102 block is the same thru out much of the series. So what is the differences in the actual engines?... Crank? Head? cam?? Or is it just the injection pump is turned up a little more giving the engine bit more output on other models????.

Just wondering if I got to rebuild anyway if it would be wise to also update the engine at the same time... for one reason... looks like parts availabity for the 1102 specifications is getting smaller. If it is cost effective using a later model rebuild kit and also swapping out whatever is different such as the head, crank or, cam??? might keep it in a range where parts will be available longer into the future AND give a little more oooomph to the engine.

Further investigation said the crank and rods are the same between 1102 and 1302. (and everything on the net is true) Piston bigger in 1302. Question then is the sleeve thicker on the 1102 or is the bore and sleeve larger on the 1302 block. If larger bore in block...... question remains would be; can you bore out 1102 block to same speck as 1302 and resleeve with 1302 sleeves.

Not being able to find a good parts manual for L235 has made this real difficult to get desired info.

then again would 5 over pistons in the 1102 net you around same output as 1302 anyway?

thanx........ so far not much help. I don't know how well Kubota cross references part numbers between models. Also does not answer things like say..... is/is not block same just bigger/smaller bore than another... or head is the same but one has bigger valves and valve seats, cam is all same just different lift and duration for better performance etc.

I'm not sure if you gave this answer or not, but what is cast onto the motor right behind the injection pump or hydraulic pump?

Might take me a few days but I'll get that number. (tractor is not at my residence)

In re reading this I think I got the wrong numbers. These are the ones "stamped" not "cast" onto the motor.

A-01436

I did write a note while out there on another day that 1115cc was cast on the motor but this just indicated to me that it was the cubic centemeter output and not an engine number

With the #'s it could be you have a 1101A or a 1102A really doesn't matter as they have the same exact specs??? Kubota is know for odd changes that either add up or don't add up to much.
As far as 1101A or 1102A piston DIA 2.989 to be bored out to 1301A or 1302A piston DIA of 3.25, I think you would be asking for problems.
That's a lot of steel when it comes to a block, but with it sleeved it might take it.

Send me a PM with a email address and I'll send you a sheet of a bunch of motor specs for you to compare, and a WSM for the tractors they used those motors in.

PMed ya. If all other dimensions of the blocks are the same....... cranks swap, rods swap...... then Kubota had to have shaved the same amount of wall out to go with the larger piston too. Blocks not bigger. If the head is the same then cooling passages are the same too so they were not moved to gain more metal between cyclinders after making the 1302 with larger bores??? Hopefully your info will shed some light. I dont know if the heads are the same.

I have recently found out from someone else that apparently the D1005 and the D1105 are the same..... with the 1105 having the IP tuned up 600 more RPM being the only difference. Will be interesting to see if the part #'s are the same between the two.
