I appreciate it Bob. I can do fun after, when things aren't so hectic. It is water cooled and it is 10 hp. The z400 engine was used in the Kubota G3200 mower. Must not have been very popular, not that many around of this engine.thebuildist wrote: ↑Thu Sep 08, 2022 7:03 am I guess you're making sense. But if I were anywhere near you I would personally help you get that diesel engine in there. It's just such a nice end result.
And I don't think Kubota made any water-cooled diesels less then about 16 or 20 hp. One of the little Hatz style air-cooled diesels could be 10hp or under, but I think anything water-cooled is going to be plenty of power.
But again, I recognize you're doing the responsible thing.
just not the FUN thing.
Back to reality though. Today I did some scouting in Princess Auto (similar to your Harbour Freight but probably fewer options and stuff). I have this more modern and new, never used 420cc engine claiming 19 ft lbs of torque and 16 hp. It came with a parts OHV 446 at some point.
It also came with a new hydraulic pump and proper mounting. The pump has 0.732 displacement and 12.7 GPM.
A little more than the original, but I suppose that should be fine. Has ORBF 12 inlet and 10 outlet. The result of my scouting was some fittings: a 3/4 ORBM to NPTM straight adapter, and then an NPTF-NPTM 90 degree elbow. Will try to connect a 3/4 hose on this to go to the tank.
For the outlet I got an 1/2 ORBM - 1/2 JICM.
I'm thinking to replace the current steel line that goes to feed the TCV with a flexible hose of appropriate size, to give me flexibility in mounting the engine to the frame. Might not have yet the right fittings or hose.
Oh yeah, and I had to replace the L095 flex coupling that came with the pump and motor, seemed to me it was too small. Got the L099. Bore size 3/4 on the pump side, and 1" on the engine side.
