MTU Engine 4000 Series

05/01/2012 5:08 PM

What are the problems when you don't use a lube oil priming pump before starting and the engine is provided with one?

After many starts, your engine may begin to sound like there is a little man in the oil pan beating on the block with a ball peen hammer.

Yah, I would assume if the manufacturer went to the trouble to install a lube oil priming pump and include the operation withing the manual...

There was a similar discussion regarding a generator a few weeks ago:

It may answer your concern.

I'd say the biggest problem would be the voiding of the warranty if recommended starting proceedures are not followed.

Why, in the name of everything that is sane, don't you RTFM and call the manufacturer.

The prospective life of the engine will be substantially foreshortened. The maintenance budget for it will need to be increased. The availability of the engine to the process it is intended to power will be reduced due to down-time over and above what would normally be expected, and the capital expenditure bid proposal intended to replace it at the end of its service life will need to be brought forward in time. It can also be seen as career-limiting behaviour by the individual that didn't use the priming pump, invoking, as a long shot, the need to find employment elsewhere and possibly in a different field. Ridicule within a global forum such as this is also a significant possibility.

Will that do?

Maybe you could save money by not putting any oil in it at all, then you could save even more because you wouldn't need an oil pump.
I suggest you buy a LynDoorTM unit designed by accountants for minimum outlay.

'Troll'?............premature wear, oil isn't called a lubricant for nothing. Obviously the engine oil pump doesn't provide sufficient lubrication on start-up, and it takes longer than an optimal time to reach sufficient oil pressure within the engine. I'm guessing its probably an after thought by Detroit after they have had premature failures of that series in the past.....could be wrong though. Either way, if its there, its a no-brainer, and you should use it.

Welcome to the insanity.

On that particular engine series, There was a contractual obligation to a supplier of components to the the engine manufacturer to purchase a large quantity of small lubricating pumps. In order to not have to absorb the cost of these pumps, the company decided to fit each engine they sold with an oil priming pump, and pass the cost of the oil pump along to the end user. You can just throw away that pump. It is strictly for decoration only.

Are you kidding us? Everything that is lubricated by engine oil is going to start to wear as soon as you hit the starter. Everything!

You are a month late: That special day is April Fools, not May Fools.

Please completely disassemble the engine. Examine all the parts that move relative to other parts. Where they touch, there must be lube oil ("lube" is short for lubrication) to prevent these parts from wearing excessively. Imagine a force that would cause oil to drain away from these surfaces if the engine has not been run for a while. Gravity is one such force.

Obtain the parts prices for all of the pieces that would wear from lack of lubrication during startup. Add up the cost of all these parts. Imagine that amount being taken from your own bank account. Would having your bank account reduced by that amount be a good thing or a bad thing?

hello,

we have 4 diesel engines MTU 12V4000M71 and no priming lub oil pump.

engines are 10000hours and no problems because of no priming pump.

at 9000h we inspect 2 connecting rods bearings on all 4 engines: very good condition.

this is only my experience

Seriously?

One of the problems might be finding a suitable junk/scrap yard nearby to weigh the <... MTU Engine 4000 Series ...> in.
