Washington injectors, finished!
This week, OTM Inc finally finished rebuilding the injectors for the Timber Heritage Association‘s Estep yarder. Two of the three operate well, but the third has a smashed tip that I hope they’ll order replaced soon. In the meantime, all three injectors look great!
Enterprise injectors, begun
Martin from Hatch & Kirk is working on a new injector nozzle for a G Enterprise, so we dug up one of our spare heads to check the spray angle and tip depth into the cylinder.
Martin and I also disassembled four injectors from the Maris Pearl, then inspected, reassembled, and tested each. It turns out that even though they were leaking, three of them were within specs. The fourth was ruined and it’s a good thing we changed it out: the pintle had been badly scored, possibly from dirt. We’ll discard the worn parts and save the rest for spares.
Lightship 83 Request for Proposals
In the office, we’ve made a bunch of revisions to the draft Request for Proposals for the Lightship project. Hopefully, it will go out on the street soon.
Work on the Arthur Foss
OTM Inc is assisting Ocean Bay Marine in buttoning up the Arthur Foss. We’ve decided to pull the tarp and seal up the wheel house as best we can with the funding available. This will bring the work on the wheel house to a good stopping point, but not a finishing point. We hope to tackle it again next summer with renewed funding dedicated to the project.
Work on the Maris Pearl
Meanwhile, back on the Pearl, we’re looking for water leaks in the engine, as it seems a few cylinders are leaking water into the base – not enough to turn the oil milky or anything, but still a few drips when it’s cold (none when it’s warm). It looks like we will be changing out some cylinder heads soon.
In future news, OTM Inc is planning a trip south to see the Portola and the Sobre las Olas. We got a request to perform an engine survey for the Portola, in addition to doing a few repairs and acting as engineer for a few trips. A potential buyer who obviously has really good taste fell in love with the boat and wants some technical advice and assistance. I’m looking forward to seeing her out cruising again, so I hope the sale works out.
While in California, I’ll do some more work on the Sobre, another beautiful heavy-duty yacht. This ought to be a fun trip. Details soon.
OTM Inc, the educators
For years, we at OTM Inc have been using heavy-duty diesels as training aids to people new to diesels. Our collaborative high school classes have won high praise, and now we’re working with The Anchor Program to design more educational opportunities for those interested in engines and boats. More on this later.
