      This topic has 4 replies, has 3 voices, and was last updated byTony Athens 4 years ago

      June 14, 2019 at 1:06 pm Stepping into the fire a bit here. I’m definitely wet behind the ears when it comes to Cummins knowledge. Still, having read Tony’s posts for years I know I’m in the right place. We’ve the possibility of picking up a trawler at a very reasonable price. What I know: It’s Cummins 5.9 equipped, early 90’s vintage, naturally aspirated and has about 7500 hours. As of right now, those are the only facts I have in ha…

    • Epoxy and Rectorseal #5

      This topic has 2 replies, has 2 voices, and was last updated byNot 5 years ago

      September 24, 2018 at 10:32 am Yes, I’ve read Tony’s sealant tips about NPT, SAE and push lock connectors. Epoxy and Rectorseal #5 are in hand. The part I’d like clarification/advice on – epoxy on NPT threads. Specifically, what is the best practice on selecting which NPT threads should have it as opposed to Rectorseal? I’m about to undertake a complete replumbing of my fuel system, with the exception of the return line. I’m replacing every…

      September 24, 2018 at 7:53 pm Thanks, Rob – I’ll fetch some Tru-Blu. I’ll try it everywhere first, but I do have a couple joints that may need epoxy for the reason you mentioned – orientation. Seems like there’s always that valve or elbow that feels too loose when oriented correctly, but too tight to get another turn out of.

    • Priming bulb inline w/o valving

      This topic has 2 replies, has 2 voices, and was last updated byNot 5 years ago

      September 6, 2018 at 1:02 pm I’m about to order up a double double filtration kit, but still debating on the squeeze bulb kit. I don’t mind the expense, but it won’t fit in my engine hold. There’s barely enough room for the double double kit. From what I’ve read of Tony’s posts, it seems like the only significant concern with priming bulbs is one of flow restriction – hence, the valving to bypass the bulb in the complete kit sold he…

      September 6, 2018 at 4:52 pm Thanks, Rob. Can’t believe I didn’t think of that before. Basically, I’d just planned on swapping out the Racor 500 for the double double in the current engine hold location, assuming it was there for a reason. I could certainly remove the Racor completely, splicing the fuel line together. There is indeed, a ton more space by the tanks under the cockpit than in the engine hold. The double double would easily fit there and actua…

    • Yanmar 4LH-TE – Proper Oil Filter?

      This topic has 3 replies, has 3 voices, and was last updated byNot 5 years ago

      September 1, 2018 at 12:20 pm OK…on paper, this seems obvious. However in person and with products in hand, not so much. I’ve got two oil filters for a Yanmar 4LH-TE in hand, and they couldn’t be more different. Let’s start with the original filter. I have the original build sheet for my 1988 Nordic Tug which contains many details, including the Yanmar oil and filter part numbers. 119100-35100 is listed for the oil, and while there’s a WIX insta…

      September 5, 2018 at 1:32 pm Well Tony…I gotta live with what I have, crap or otherwise. Engine runs beautifully and I can’t justify doing anything other than keeping it running while I own the boat. Now…when our upgrade to a Nordic 32/37 happens in a couple years, I’ll definitely bend your ear on those. All eras we are interested in are Cummins equipped. Rob – thanks much for the pointer to Bayshore Marine. Prompt response, very knowledgeable …
