Hello Joe, I can remember years a go doing an in hull rebuild of a 6LX unable to be removed from the wooden boat so I devised a set of engine mounts that were hinges and we removed the top rocker gear and then tilted the engine near 80 degrees till we could remove both the heads and cylinders and crank , it was by far the hardest rebuild I've ever done only for the cramped and dimm Conditions and all this work was caused by the owners use of oils ment for a modern turbo engine
Hi Joe, I think the first picture of the leg out of bed engines you showed was a 6BT Cummins, good engines too when looked after, Did I see you had a fine looking 8LXB on FAFB for sale, are you going to do a 8LXB video?
Damn , but those Conrods are truly MASSIVE . I've worked on Paxman's and MTU's so I've seen bigger , but those are Huge for the Size of that Engine . GARDNER . Built to LAST and to hold together . No Matter what .
The 6LXB is an amazing engine, incredibly robust. I have come across Leyland Olympians still running in revenue earning service with engine knocks like that and still maintaining some degree of oil pressure, sufficient to not alarm anyway. The drivers being 30 feet away at the other end of the bus were unaware until something major gave way and all forward motion ceased. But the consequences of that situation are nowhere near as bad as it is for a boat at sea.
Looking at the state of those pistons I would say that that engine had more than a few miles/ hours under its belt and was way over due for an overhaul. They weren’t affected by the lack of oil pressure as there wasn’t any signs of them picking up and it doesn’t look as though they had any overheating issues. It was fairly common to find broken piston rings when we pulled them down and as the original Gardner pistons didn’t have “armoured “ ring grooves piston ring groove wear was common. It would have been interesting to see what the bore wear was like, fairly well worn I would have thought. With the bottom end… it does definitely help to have oil pressure, in normal circumstances the crankshaft which was nitrided was just about bullet proof and although with high mileage engines it was common to find the bearings showing copper there wasn’t usually that much wear on the journals. A quick check with a mike to ensure that they were in tolerance and anew set would be fitted with no problems I have known Gardners to bust con rods but it was not at all common and was usually because someone did something that the engine wasn’t designed to do. The two cases that come to mind was that it was decided by some bright soul to try and get a 6HLW to run at 1850 rpm instead of 1700 and another bright spark who decided on a 6LXB that with a 4 bolt big end tight was good but tighter was better, he stretched the bolts they failed and the end result wasn’t pretty, ventilated crankcase anyone…
Company I do work for has insisted on unmanned engine rooms with there new fancy alarm system. (To save money on having to employ engineers) since they implemented this they have lost 4 cranks on big deutz engines and a mirleees k-major
@@tangentgardner pity, easy to do, hard to fix. Yes, alarm would have saves it. But in a single engined boat? Would they have been able to stop the engine and fix in time?
In 50 years of truck mechanics I have never seen anything really wrong with the bottom of the engine , dropped valve heads were another thing , they do not like over running them down hill .

Just discovered your channel, to me it's like winning the lottery as Gardners are my favorite engines and I just do not know enough (yet) about them
always a real pleasure JoeMcC…a lifetime of knowledge and unusual insight. Thank you kindly⁉️👊🔥
My favourite kind of engine, in buses. In NI the old "Bristol REs" had this engine in its horizontal form.

excellent vidieo it would be nice to see a little of the installation process sometime. many thanks.

excellent video Joe, as always very informative

It is a pitty the old engine but the dust but the replacment looks great keep the vids coming Joe

I've never heard of the saying - put a leg out of bed
Joe can you recommend the make of an oil pressure alarm?
Would you recommend straight 30 for all Gardner's ? Im purchasing a 6lw that has been mated with a generator
Watch the video at 6:40 !
Whatever happened about the Brigantes engine?

Oil... Why did it lose pressure? Low level, pump failure?
Crewman accidently broke off a small oil pipe :-(

Knocking like a Jehovah's witness! Poor old thing.
