Bernie The Bolt

[hpeer]

AN engine manufacturer that shall remain nameless make a raw water pump that is - at first look - perfectly accessible. That is until you realise that whilst it is easy enough to unbolt it, in order to remove said pump from the engine means removing the front foot & engine mount.

So a simple raw water pump overhaul then turns into a major job to support the engine and re-align. ?‍

Yanmar 4JH4, change the mounts and change the pump kn same interval. $2,300US.

I had a similar problem on my 1968 Morris Minor. The brake master cylinder is located in a hollow U shaped chassis member and secured by two through bolts. There is plenty of room to withdraw the bolts from one side but on the other side the suspension torsion bar runs immediately adjacent. Guess which way the bolts were fitted.
After having to remove the torsion bar to remove the master cylinder I reversed the bolts when replacing them!

This is not an engine but I would happily keel haul these two if I ever saw them…

Servicing a brand new toilet that is not connected to anything on a workbench is MUCH easier than crawling around the heads having to manufacture screwdrivers that fit into the available space on slotted screws (why not hex?) that have been there for a while and are ‘covered’ by the waste pipes that were fitted over them in the factory so there is no clearance in the heat of the day etc etc

A ‘simple’ 15 minute job took me half a day. Grrrrr

Engine cooling water pump on Massey-Ferguson tractors that are inside the timing case and gear driven off the timing gears. OK till it leaks then the antifreeze goes into the sump and destroys the oil, wrecking the engine, Half the tractor has to come off to change a pump and the timing reset. Daft engineering

Whilst I will admit to ploughing a few sandbanks, I have not managed to plough any fields with my boat ( yet) so I do not see how reference to tractors is anything other than a thread drift
Or perhaps you intend to sow some seeds of doubt into our furrowed brows

Me too. Yanmar 3GM30F?

To be fair, getting the pump off/on again's easy though. besides a bag of spare impellers we had a spare pump too; switching out the pump was <10 minutes, then you've all day to replace the impeller and as there's no rush you might as well do the spindle a favour and change out those crappy bearings and seals that they build them with too.

It certainly wouldn't be fair to blame Yanmar, but one of the first tasks I did when we bought our boat was renew the engine control panel screws, installing six new/matching ones; it only had five in when we bought it, but it still required three screwdrivers and an 8mm spanner to remove it.

Removing the starter motor on a Volvo 200x engine is difficult because the lower Allen bolt has insufficient space behind it to get a normal Allen key in. It requires a ball-headed Allen Key, or a very short one.

But on the positive side, it makes buying an old BMW RS/RT motorbike a worthwhile idea as that same cut down allen key works for their fairings' lower mounting bracket bolts. Which reminds me that I need to grind down a new socket for adjusting the BMW swing-arm bearing nuts, mine got left with the boat in NZ - it was perfect for the centre hub on a Whitlock steering wheel

Can't speak for others, but I'm certain there are more than a few MABs with marinised Kubota 'lumps' installed. I had one.... they're tractor engines innit?
Then there's the BMC 1800 of song, story and legend - also a truck engine - fitted to lots of boats.

True, but there are people who put tractor engines in boats! The Morris Minor is not a boat is it?

Massey Ferguson engines ?? well one lives & learns

To be fair the original liquid cooled Kubota engines were actually designed as marine engines so not " marinised" in the way some of the BMC engines ( for example) may have been. A different range was designed for land based use.
The Kubota marine engine , I believe was built from the ground up as a marine engine. But not being a marine engineer involved in the history of these engines, I may well be wrong. Others more knowledgeable than me may comment to the affirmative.
If not then I will stand corrected.

A VERY long time ago, my Dad and the rest of us looked at a motor boat. It was powered by two Scammell lorry engines. Unfortunately, the rest of the boat was made of plywood panels unsupported except at the edges. We did wonder what would happen if the engines were ever started!

It's a good warning not to buy a boat with a Massey Ferguson engine fitted...???

 

[zoidberg]

I was never much enthused about delving into engines.... so I tended to avoid 'em.

Once I discovered I was the owner of a Kubota 'lump' inside a MAB I'd acquired, I sought some guidance. Every ag-engineer for miles around pointed me towards Old Man Hurley's setup which fortunately was just on t'other side of Bath from me.

He knew the model in question.

"It may run and run for years without a problem, but if you need spares, finding and getting them could take the rest of our lives . And getting someone who can take out the old and fit the new to the standards we do here would also be a challenge. In all that time you'll be stuck in a marina somewhere, with your engine in bits in some waterside workshop. The costs will make you weep.

Buy a new one, get it properly commissioned, then if you need something it's days - not months..."

I did 'zackly that.

Neither is a BMW RS

I think you are correct about that one. You have just reminded me that back in the late 60s a student friend of mine tried to "marinise" his Morris Minor in the Norfolk Fens one frosty night. Unfortunately, without much success. I expect that they used a tractor to pull it out of the canal, but I would not know if it was a Massey Fergusson. From what he told us, it was not much use as a car afterwards either

I worked as a field engineer for a large computer corporation last century. We had a process whereby our guys were seconded to the manufacturing plants in order to make sure the products would be serviceable using our tools and training. We had the authority to "stop the line" if a problem was not addressed. Obviously not a sentiment shared by manufacturers nowadays.
