All the dry sump parts arrived last Wednesday except for the pump itself. There’s plenty to do without it though: modify the tank for a -16 scavenge fitting, add a -10 fitting to the dry sump pan for the turbo return line, mount the tank and pan, attach the crank pulley and dry sump mandrel, and fabricate an alternator mount. I got about half of this completed.

The tank and pan were modified without issue. Attaching the pan to the engine however, hit a snag because the manufacturer didn’t leave enough space around the OEM bolts along one flange – unlike all the other flanges – and the bolts jam against the wall of the pan. It’s not a big deal but annoying since the hardware stores with metric Allen head bolts were closed for the holiday.

The ATI crank pulley went on no problem, until offering up the dry sump pulley mandrel that mounts to the front of it – the OEM crank pulley bolt interfered with it and had to be shortened. With that fixed, the mandrel (for the dry sump pulley) was attached to the nose of the crank pulley with three supplied screws and surprise, one had a different thread pitch. Nothing could be found in the documentation to indicate that this was on purpose, so a note was sent to the dry sump supplier, which of course is closed until Monday.

As long as there’s stuff to do, none of the above is a real show-stopper, but it is a little surprising. Perhaps it’s because it is a dry sump that’s the issue; maybe only pros tend to install them and they typically have real shops, do everything custom anyway, and have a good stock of fasteners. Meh, it’ll get done regardless.

Then there was the alternator mount, which consumed a surprising amount of time. As said before, it would have been much easier to use a custom alternator, but it being sole-source was troubling. It seemed wise to sink the time into it – once – so that a Chevy C1500 diesel truck alternator fits in case it goes out in the middle of nowhere. Anyway, it’s done – probably. The concern is the narrow adjustment range due to the alternator’s arc when tightening it down. If I can’t get a 39″ belt it may take another redesign, but like I said, it’s better to have it be painful one time instead of every time the alternator needs replacing.

In other news, Lulu, Midlana’s book printer, is offering another of their year-end discounts. Currently (subject to their whim) you get 35% off the Midlana and Kimini book, so now’s the time to order for Christmas!
