April 2, 2023 at 5:20 am Hi Guys Has anyone produced a timing gear cover with PTO mount that can be used for mounting the pump on? My boat on the port engine is a pig.. very serious pig to change. To do easily the aftercooler and HX have to come off (HX so i can stand and bend over the engine) everything is done pretty much one handed and can take anything from 4-6 hours. SB engine is 15 minutes.. kinda says it all really! If the pump was front mounted it would still be…

Aftercooler pitting
This topic has 2 replies, has 2 voices, and was last updated by
2 years ago September 1, 2021 at 5:36 am So about to put my intercooler back together and it has the typical pitting on the internal circular face at the bottom of the body casing, it doesnt cause any issues with sealing, however I was wondering if it was worth filling the pits with a skim of JBweld or something like JB tankweld putty just to prevent condensation etc from reacting and pitting even further? Just trying to eek more years out of the housing! Steve

15si vs 19si

3 years ago February 16, 2021 at 7:43 am Hi guys My alternator on the SB engine has died. It’s on a 1997 6bta and is a 15 si. Sourcing a new 15si in Aus is proving problematic as there is only one brand and the bearings and alternator howl when running.. shop is refusing to supply now as they have had a couple like it. I was wondering if the 19si is useable without any mods. I’ve searched and can’t find frame drawings anywhere. The 19si is more readily available. I…
