    • Strange pieces

      This topic has 8 replies, has 2 voices, and was last updated byRob Schepis 3 years ago

      July 16, 2020 at 9:54 am Last year I noticed these small pieces of ‘plastic’ under the front of the starboard engine, 1999 Cummins 6bta 5.9l 330hp. Nothing like this under the port engine. Port – #45766133 Starboard – #45764308 I cleaned them up and put in new absorbent pads and had new belts installed. I now see more pieces, the mechanic I use doesn’t know what they are. About to head out on an 8 week vacation and would like to know if…

      July 23, 2020 at 4:09 am Right you were confusing tensioner vs idler. Tensioner is replaced with new, not just a new shim. Itā€™s not expensive nor difficult. Idler pulley upgrade is something else worth searching on the website and forums here.

    • ZF 80A filter replacement

      This topic has 9 replies, has 4 voices, and was last updated byGraeme Walker 3 years ago

      June 23, 2020 at 2:53 pm I thought changing my transmission oil/filter was going to be an easy job, however I don’t appear to be able to get the ‘plug’ back into the hole in the transmission. Everything online I’ve seen says just place in hole but the o-ring won’t fit. Do you have to fit the filter to the ‘plug’ before putting into the hole? Why is there a tighten and loosen component to this? Does the ‘plug’ com…

      March 9, 2020 at 10:23 am I purchased my ‘oil change’ pump from https://2k-pumps.com/ Specifically https://2k-pumps.com/marco-up3-oil-gear-pump-for-lubricating-oil-12-volt-16402012/ I see they are on sale for $207 at the moment.  Much cheaper to purchase from Italy than USA distributor. They ship from Italy with $15 worldwide shipping cost. Very pleased with they customer service, considering purchasing a fresh water pump to replace existing noisy diaphr…

      March 10, 2020 at 7:25 am See this is what I love about this forum and business,..

Support given even when a sales is not likely…No protection of sales just genuine Opinion. This will lead to sales but not enough people in the marine industry realise this. As always appreciation to Tony and team for their hard work and contri…

    • Impeller blades missing, an issue?

      This topic has 4 replies, has 3 voices, and was last updated byGraeme Walker 5 years ago

      September 27, 2018 at 4:00 pm I’ve just taken possession of boat with twin Cummins 6BTA 330HP engines. During the seatrial the Cummins rep had a look at the impellers and wouldn’t let us go out without replacing them, the port impeller was very chewed up and missing 4-5 blades. Sea-trial went well and engines go to WOT without issue, no smoke on start, ~700hrs. I asked the rep whether the rubber impeller blades would be an issue as they are now floating around…

      September 28, 2018 at 8:15 am Appreciate the comments, will run only at hull speed for now, only went at WOT for seatrial for brief period. I have maintenance plan scheduled for the winter season, it’s getting longer. I’ve been ‘grunting’ my way through your tips, very informative. Thanks.
