Constant Torque Hose Clamps
This topic has 7 replies, has 6 voices, and was last updated by
1 month ago March 27, 2024 at 9:14 am Curious if there is any specification or guidance on tightening these hose clamps.Ā My impression is that the spring needs to have some give both to tighten and loosen to allow expansion.Ā Ā Anyone have any advice vs just tightening them ‘tight’ like normal hose clamps.

3 RepliesJuly 19, 2023 at 6:48 am Maretron makes a fuel flow analyzer but requires a significant amount of auxillary pieces to setup and calibrate. Ā NO matter what type you settle on they are all worthless unless you can gaurantee there is no air in either the supply or return lines. Any bubbles and they wonāt work. Ask me how I know. Check with a couple of clear Ā vinyl hose segments in the system before getting started and save some headaches.ĀLast Post by:

1 ReplyMay 21, 2023 at 10:48 am If not a gauge issue, then look extra carefully for the broken hose clamp/loose hoseĀ on the orange hoses allowing a boost leak.Ā Lose boost = all of a sudden will raise the EGT and or make dark smokeLast Post by:

If one battery is failing the parallel connections will show a good average voltage high enough to make things look OK.Ā Ā The meter will likely show a good average voltage. However as soon as you try to crank the engine the failing battery will cause that average to drop big time. I have…Last Post by:

Use Barnacle Buster?? 2006 QSB5.9-380
This topic has 8 replies, has 7 voices, and was last updated by

December 14, 2021 at 1:28 pm I want to do a Barnacle Buster flush on my motors but am worried about the chemicals making it “too clean” and maybe causing an internal leak at the fuel coolers or aftercoolers. I read one post and after a BB flush the person had water in his fuel due to a leak in his fuel cooler. My raw water system was relatively clean during the last cummins engine service about 2 months ago but that doesn’t protect me from a failure. …

8 RepliesDecember 20, 2021 at 7:14 pm I have used Rydlyme at the end of the season and when I take my coolers apart they look new. It will not cause leaks because it only gets rid of the marine growth and will not hurt parts. They show a man pouring it in his hands while holding a clam shell. I did it as a test and it dissolved the shell and did nothing to my hand.Last Post by:

2 years ago September 14, 2021 at 11:12 am I’m new to the world of Cummins engines but I would like to install the Envirovent CCV system on my 2002 6BTA 370hp engines to mitigate the blow by gases. I would prefer to install the timing cover option but after watching the installation video and reviewing my condition I have something (not sure what it is) where the system connects to the timing cover.

6 RepliesSeptember 29, 2021 at 2:30 pm I didn’t use any additional parts except those from the Valve Environment Cover Kit Seaboard supplies except the additional valve cover with oil filler cap. They include a T in the kit. All is the same else wise. Just tucked in the hoses a little differently to keep it all inboard of the outer dimensions of the engine. I did not want to take off the Heater element and turn it 90 degrees because I will never use it here in South Florida…Last Post by:

6BTA Aftercooler Alignment

3 years ago July 14, 2020 at 7:39 pm Hi, I’m trying to service my aftercooler on my port engine. The core came out easily, probably too easily because I forgot to take a picture before hand. Now I realize there is no alignment arrow on the end of the core. One side is just stamped “ARB” No nice little arrow. Any hints?

Bilge Paint

4 years ago March 10, 2020 at 12:26 pm Hey All, Long story – short is dropping in a pair of new CTAs (450). Taking the opportunity to replace hoses and really dial in the engine room. Wanted to get everyone’s opinion on bilge/engine compartment paint. I’ve seen many different options online Total Boat, BilgeKote, then a lot of people swear by good old rustolium enamel (oil based) and add hardener…. Would be a very cheap easy option as opposed to epoxy base…

I had to buy it out of state and ship it………..Maybe the best coating I have ever used–Went on heavy, covered all in one coat, and in 2-3 cool days is was like a porcelain finish.. I would have no issues using it in a bilge. Yours reads like the same product.Last Post by:
