LN thereby seems to corroborate Grant's contention that just removing the seals ensures adequate lubrication. And yet, LN beats the drum for the Solution, touting its pressurized direct oil feed. Isn't that unnecessary according to their own statement? |
To answer your question, Jake Raby actually ran an IMS Solution for a prolonged period with the oil feed line disconnected during the system development and testing; Jake noted that the IMS Solution survived this without issue on just the oil mist inside the engine. But knowing that Jake is a decided "belt and suspenders" type engineer, he kept the oil feed line, which delivers a slow, controlled amount of oil, because he knew that a lot of the Solutions would end up in track cars where heat build up in the bearing is more severe. He also wanted this product to be a "life of the engine" answer to the original bearing's short comings.
Having had the opportunity to see IMS Solutions after hours of track time on dedicated tract rat cars, I think he did the right thing; these Solutions looked like they just came out of the box.
