Yanmar Barras Shire Water Pump

[Nightwatch]

Gloom. Detected a drip from the water pump. Going back to my motoring days this would indicate the requirement for a replacement.

 

Looked online at Yanmar pumps generally and genuine items are a great deal more in cost to a after market one. Part of me says ‘genuine’ another part of me says ‘Non-genuine’ parts.

 

My thinking is, the engine was installed in 2002. It very rarely exceeds 2000 revs. It doesn’t run every day. 
 

Is it worth considering a non genuine part or false economy?

 

Next question. Where best to get one from. I’m in Skipton. So is the boat. I can probably fit myself.

Buy from anywhere but a Barras agent. Yanmar are industrial engines, plant, tractors generators etc. So buy from a Yanmar plant distributor.

 

You will need to find out the Yanmar engine type, usually cast on the top side of the block

I know the number. I suppose luckily I’m in the right place for farm vehicle supplies and parts.

 Barrus put me onto Selby Boat Centre who are their agents as would not supply the part I needed direct to the boat yard I was in, had absolutely no joy from their authorised agent, finally just bought the genuine part off Ebay😄

I would have no worry about a non-genuine one as long as it is from a brand that is accepted in the vehicle repair trade.

How would I ascertain that Tony?

I would go to a few independent garages/workshops and ask them. I was happy to trust certain Motor Factors in my area until Europarts seem to have taken most of them over. I used to know the brands I felt I could trust but not any longer. Do what Tracy said and look for an industrial/horticultural/agricultural agent.

[Nightwatch]

I’m on the case. Thank you.

Knock me over with a feather, checked this morning before and after running the engine. No drips. Stone dry.

 

If it ain’t broke, don’t fix it.

 

However, I will keep checking it of course.

Please do, and keep looking for a non-marine source. That behaviour is typical of a water pump in early stages of failure in that they only leak when they think they will. Sometimes stationary, sometimes running, and sometimes for no good reason. Dammed tricky things, faulty water pumps, especially in the early stages of failure.

[Nightwatch]

In the mean time Iam having difficulty identifying the engine.

 

I have the number from the rocker cover. The documents from the installation show the same series.

 

The number I have is 2203 0201868. I called one supplier and they wanted more. I haven’t got more at present.

 

But I will persevere and keep looking.

That is how mine went, thankfully an easily sourced Lister bit

There should be two sets of numbers, the original Yanmar stamp and the brass plate that Barrus put on once they have tinkered with it.

The Barrus plate is on the top 

rocker cover and the Yanmar stamp/plate is on the side by the starter motor.

Something like this from a 2003 Barrus.

  If it is the 4TNE84. You can get them off Ebay if you can’t find in your area or cheaper.

Run out of coolant? 

[Tracy D'arth]

Sneaky devils:  water pumps. Some only leak when running and spray a microfine mist, not a drip, so you can't see it. When the engine gets warm it evaporates as fast as it leaks, convincing you that its not leaking.

 

A raw egg in the water often stops the leak,-------------for a while!

Instead of purchasing a new pump you could get yours refurbished, I've used SP Water Pumps Ltd before, great service at a reasonable price...
