Exactly! I measured the "magic number" back at the start and came up with some .470 aluminum plate.

As for the pilot shaft. I considered this: Drill out the crank using the current pilot bearing as a guide. Get it nice and centered using the pilot bearing, and then, pull the old bearing out, enlarge the hole slightly, replace the pilot bearing with a new one, and then get the tranny colinear using the new bearing as a guide (along with the dial indicators). Nothing is settled yet.

That should work! I probably should fire up my Diesel Metro. Its been sitting a long time.

Here's the difference between the bolts. The 5 are the flywheel bolts, and the 1 odd one is a flexplate bolt for comparison.






A freshly washed transmission:


It started like this:



The plan for tonight is to drill a new hole for the dipstick, remove the oil pan, and set the engine on the mating cradle.

Kimer, how did you move your oil filter? Mine looks like it should just swap to the other side where the block off plate is, but... the block off plate does not key into the oil filter mount...

Wow, I made mine in October 2008. I THINK I made my own block off plate for the oil filter on the injector pump (RIGHT) side of the engine. The thing that gave me concern was that by using brazing rods, I poked inside the oil passages to the new location and determined that the present passages would BYPASS the oil flow through the oil filter.
I made a disc that covered most of the passage in the engine block in the NEW filter location and it had a channel cut into it that directed flow into the outside holes of the spin on filter. This disc was held in by the hollow bolt that the filter cartridge spins onto. The oil flow comes out of the block through the slot in the disc, enters the outside holes of the spin on filter, then clean oil exits through the hollow filter mounting bolt back into the engine.

You have 3 oil holes under the plate covering the new filter location. The 2 outside holes will connect to each other if you just spin on the filter as is. My blocking disc covered one hole and forced the dirty oil to go through the filter and out through the hollow spin on bolt, the third oil hole.

I will dig up my old laptop that I was using in 2008 and see if I have the photos of that plate. The Japanese did us a favor by keeping the same threads in the crank between the Geo and Kubota engines. The starter teeth are also the same as I recall. But I want to smack a plate of wasabi sushi into the engineer's face at Kubota who didn't make the 2 oil filter locations completely stupid proof and 100% interchangeable.

Also, I kept my wiring all stock and uncut to adapt it to the diesel alternator, starter, temp sender, etc., so I could drop in the gas engine as needed. I hate cutting wiring harnesses. I know you aren't there yet...but you can think about it in your off hours.

If my old laptop won't run and I can't access old photos, I will see if I can dig out the car and take some pictures. The 2 transmission mounts are the same but I rigged up a new left front motor mount. Also, I made a home built low thermostat housing to clear the hood. You'll get there....

Here are a few old pictures from the Diesel Geo Metro project. The oil filter plate was something that I determined was necessary at the time. I cannot recall the details but remember that oil would pressurize the filter but bypass it without that flow plate. I think I made the hollow bolt, too. Good old Harbor Freight Tools lathe! Precision exceeded only by a jackhammer.

Subscribed. Late to the party!

Well, you might have thought I died. nope. Just got stupidly busy with family B.S., the Holidays, and vacation.

I've returned to my work, and if it does one thing it sucks the life out of me. To rejuvenate my mind I work in the garage.

Here's a progress report on the Diesel Geo:


I think everybody saw this. It was the plate adapted to the engine.

The workshop:


The Plate, with the holes drilled for the engine AND the transmission:


The plate, trimmed:


So last night I mated the two parts. The engine's crankshaft and the Transmission's input shaft are collinear - it took a long time to get them just where I wanted and get the holes reamed to the correct size. I'm not sure that it's perfect, but I feel very confident that it'll work (for a while, maybe a short while maybe a long while).

You know, of course, that a clean garage is the sign of a sick mind....
My garage is a bit more cluttered.

For some reason I can't see the photos.
