D9 convert from torque converter to direct drive

Well made the mistake of going and looking at a D9 19A and I can’t justify getting it other than I want it! I’m looking to replace the torque converter to direct drive wondering if anyone has a parts machine D9 18A, I need from the flywheel back to transmission or last resort a good used torque converter for a 19A but would much rather make it direct drive, wondering if anyone on here has done this and what problems they had found thank you for any assistance.

I don't know about the D9's but I think the D8 torque convertor drive has a longer chassis compared to the direct drive.

The case and engine frame assembly according to parts book and NPR are different for 18A and 19A. No clue what specific differences are. If 19A is longer would not be impossible to convert, would need longer drive shaft from clutch to transmission. Unless there is something that would make oil clutch interfere with something in frame design.

Hi Clayton, if it worked out, would this tractor have a clutch and a 3-speed powershift? Reason I ask is that the D8LSA is almost that. It has an hydraulically-operated two-speed clutch (direct and underdrive) coupled to the 3-speed powershift, giving it 6 speeds forward and reverse. The other thing is that if you did manage to build it, that would give an option to other 19As that need unavailable torque convertor parts (I don't know if parts are available, but if they aren't, this would be a potential lifeline for those tractors)

Cheers,
Neil

No it would have a manual oil clutch and a gear drive manual transmission. Very much like 14A and 36A D8s.

Hi Neil yes Brian18a is correct it would not have any sort of power shift to it. The under carriage is in great shape actually the entire machine is in great shape except for the torque converter being bad .

Not sure what you want to do with the tractor, if you replaced the converter/clutch assembly with an oil clutch, you then have a 3 speed direct drive with a first gear slightly faster than 4th gear in a direct drive 18A.
