EMD Water Pump Identification 2

[chiefrobert]

Irecall a reference made to the rotation of EMD Marine Engines and the relationship to fresh water pumps on the engine. I recall seeing, in a parts book I believe, a drawing referring to the "Construction" of the pump being either a right hand or left hand. They drawing as I recall had right hand engines with either a right hand "constructed" pump or a left hand "constructed" pump. The same was true for the left hand engines. Can someone either verify this or correct me? Can anyone refer a site where I might get a copy of the page with this drawing?

I can say that I remember that also.
There was a manual on line but I cant find it now.
I will have the manual in my pile of stuff which I will look thru later.
I will look for the online manual later also and if I find it I will send you the link.
Could have been on the manual aboard the John Spence also.
But I do remember that fact so I do agree with you

Thank you for the reply. If I recall correctly the drawing was in a parts book near the front cover. I worked for Offshore Logistics and others and have 21 years experience with EMD's and I have now been awayfrom them for 6 years. A friend and I were discussing this and it led to "I'm right" "No, I'm right". So here I am. Thanks and what ever you run across I would appreciate hearing from you.

Thats part of the manual
Cant find the table of contents.
Maybe you will have better luck.
I go bed now
I will look later as I said
The whole document is on line somewhere.
Just keep finding bits
Better luck tommorow

This info was found from the following link.
On a ship I was on, we had one clockwise rotating engine and one counterclockwise rotating engine to offset the prop rotation.
I think that the fuel and oil pumps were of positive displacement type so they pumped equally well in both directions.
The water pumps had to be changed because they have to pump in the proper direction according to design.
Quite an inexpensive way to change the rotation of the engine.

Thank you for the reply. I will follow this link and see where it leads me. I am preparing for crew change today. I really appreciate your time and assistance.

EMD engines are set up to rotate one direction or the other, the designation being a "Right Hand" or "Left Hand" Engine. The difference in the water pumps is the configuration of the impeller based on the direction of the Accessory Drive Gears.

In other words, and LH engine uses a LH Pump assembly (EMD Part Number 8347607) and a RH Engine uses a RH Pump (EMD Part Number 8364237)

Keep in mind that both Lube Oil Pumps on an EMD are interchangeable between and RH and LH Engine

 

[chiefrobert]

Thank you for the reply. You are correct about the lube oil pumps as they are gear type and direction does not matter. The water pumps on the other hand are dependent on the impeller and volute to direct flow.

I am familiar with the difference in the rotation but if my memory serves correctly an old (circa 1970's early 80's) parts book showed four configurations near the front of the book to aid in identifying the different "configurations".

Each of the four drawings showed configurations as follows:
Right Hand Rotating Engine; Right Hand Construction (construction is a key word)
Right Hand Rotating Engine; Left Hand Construction
Left Hand Rotating Engine; Right Hand Construction
Left Hand Rotating Engine; Left Hand Construction.

Constructed, again if memory serves correctly, meant that the water pump volute outlet was either going to the water manifold from the bottom of the pump or the over the top of the pump, depending on the engines "construction".

What I am trying to find is a link to, or e-mailed copy of this "page". I'm sure someone out there has seen and knows what I am refering to. I worked with locomotives before working on vessels and I refered to that page frequently because I was not used to the engines having opposite rotations and it was slightly confusing to me when ordering various part where rotation mattered.

I do appreciate your reply and the time you took. Thank you very much for the assistance. Good luck to you.

I am on short leave from ship right now and thought I would check this site.
I am aboard the John Spence (Off shore supply vessel) and it has the EMD manual.
I will scan the page and put it into my lap top then when I come back I will figure a way to send it if you still need it. I know the pages you are refering to.
Thing is.... I won't be back till Dec. 21st
I go back on the 17th of this month.

Thanks for the reply frankiee,

I will be working as well through December so if you can send that page to me I will greatly appreciate it. Enjoy your time at home.

If you look at the front of an EMD engine if the water pump snail has a left hand turn to the water pump outlet that goes into the block or water manifold it is a LEFT hand rotating engine

If the water pump snail turns to the right and goes into the water manifold or in to the block it is a RIGHT hand rotating engine

Also if you look at the oil seperator between the blowers you will see a raised spot about 3" in dia if it is more to the left side it is a left hand rotating and if it is more to the right it is a right hand

645Bossman,

I really appreciate your reply. I have kind of got sidetracked on this topic and have been focused elsewhere. I now have work unrelated to EMD Engines (and I miss EMD's).
I am working now with MAN B&W Ruston Engines.

Thank you anyway and best of luck to you.
