JD300 motor removal

[[email protected]]

I got it partly stripped down and think I'm about ready to split

in manual TM-1068
page 80 ; 10-4 it shows the loader frame attachment to frame without a slot
page 80 ; 10-1 it shows loader frame with slot

the instructions for removing the motor/block say to separate the motor from the front however in the example there is no loader on the tractor that would make that easier.

the instructions for clutch repair (per youtube videos i watched) they separate at the rear.

it looks like to me, my loader frame arm attachment was solid at one point and someone took a cutting torch and made it a slot.

so i'm thinking at some time someone had this split for some reason.

there seems to be 4 bolts that hold the clutch housing to the block and because the loader is in the way i was thinking it would be easier to separate at the rear then the front part could be moved forward using the space between the front of the tractor and the loader to get some room to work. also one bolt (the front) on the mounting pad is broken off (picture 1).

so the question is : are those slots there to facilitate the separation at the rear of the tractor and slide the front half forward to do clutch work?

reading clutch R&R page 10 ; 25-6 describes separating at clutch, i didn't really see any reason i couldn't get the block out separating at rear then front rather than front then rear?

but i thought i would just put it out there and see if any of the guys that may have done this might have a big warning for me in trying it that way.

other wise i guess i have to get the loader off and out of the way before proceeding?

thanks for any comments or ideas.

The slots are factory.
Deere engineers did not want the pushing force on the bucket to pull there, but to push on the trumpets housings.

To remove the engine, you need to put jacks under the loader mounts right under the engine (with loader raised and BLOCKED (like you have it), or removed), and under the clutch housing, then you remove front axle, then you remove engine.

You cannot slide the engine + loader + front axle forward, as a unit, because, the front mount is a pivot. You would have to hold it all together: Painful and difficult. That would be like removing the loader masts. The loader masts at the rear are hold with big bolts, and are some work to remove. This would be very time consuming, with unecessary hydraulic fluids loss and risks of dirt in there.
