Yanmar Maintenance parts

[Justin_NSA]

I have a Yanmar 2GM20F that I want to service before I put her back in the water. I just got her last fall so this is my first 'cycle'. These are the Yanmar parts (numbers) I want to replace. Should I stick with Yanmar or are there good quality alternatives that would be less expensive since this isn't a onetime affair. I'm not even sure that what I have today are Yanmar parts or not. I don't want to compromise the heart of the boat.

I went with Yanmar parts from TOAD marine. At least you know what you are getting. What are you saving by finding non Yanmar replacement parts?

 

[Justin_NSA]

Money basically. There are major manufacturers like Sierra and Jabsco selling direct replacement parts for Yanmar. I can get them for less money and free shipping. Just wondered if anyone uses them, had any feedback on their quality, durability etc.

The raw water pump isn't made by Yanmar, usually it's a Johnson or Jabsco so I use their impellors from an auto/marine parts store about a mile inland from the harbor. For the little secondary on engine and o-ring I use the Yanmar, it's cheap, I'll use a Yanmar oil filter if I happen to be near the Yanmar dealer otherwise a Wix from the auto parts store. NAPA usually has WIX filters available to fit most applications also, including replacements for Racor fuel filters.

Oil filter I use either of these (NAPA GOLD 1568, Fram 3593A), or the Yanmar.. not because they are less expensive, but because they are easy to find.. the Fram is available in the big Wal Marts. Water pump impellers, I kinda stay with Yanmar.. Had problems with dimensions off on a blue one so I stay with OEM.. which might be Johnson.

Two possible water pumps, and they use different impellers. The Asian made Yanmar uses a Jabsco pump which has a paper gasket. The Johnson pump on the European version has an O ring in the backing plate.
They also use different impellers.The Johnson pump has a notch in the shaft which accommodates a cross pin in the sleeve of the impeller. I happened to find a Westerbeke replacement kit that was actually the Johnson part. The pump brand is stamped either on the pump body or the backing plate.
Be really careful with aftermarket impellers, there are some out there that have been known to fail by separating the rubber impeller part from the metal shaft.

Interesting fact

The WIX number is 51358 for the oil filter. Notice the NAPA number is identical to WIX except for the leading 5. That is because WIX makes them for NAPA and they follow essentially the same numbers.

Yanmar changed from WIX 51568 to WIX 51358 about 3 years back. The only difference is the size of the canister. I think they did this so you have to buy a different filter wrench.

The fuel filter element is WIX 33262.

I do not know who makes Yanmar branded filters - but these very same filters are used on many other motors - not just those made by Yanmar.

Thanks guys. I poked the interwebz some and my previous supplier (bought an air filter) Niemiec Marine seems to have the best price on the Yanmar impeller ($39) and gasket ($2.53) plus shipping. West Marine wants almost twice as much for the part!!
I will look for the Wix oil filter (possibly fuel too) locally in the auto stores. Wix is a respected brand of filters. This is Kansas. We don't have any good marine suppliers.

The Wix site lookup feature shows these for the 2GM20F: Wix replacement on-engine fuel filter is 33262. As mentioned, the oil filter is 51358

Since you mentioned it... A birthday card shows Dorothy in her ruby-red slippers, and Toto. The front page says, "Hope you have a happy birthday in Paris". Inside it says, "Oh, sure. You get ONE wish you want to go to Kansas?".

Turns out I have the Johnson pump. It uses the o-ring like you said. The old impeller was marked Johnson but it surely can't be the original, even though a couple vane had cracks in them.

Does anyone know who makes this primary inline diesel fuel filter? It's under the aft berth on my '91 Hunter 30T - Yanmar 2GM20F. I want to replace the filter. Looks like it leaks a little too. I'm not sure how to open it. Thanks in advance.

After a dialog with a Yanmar parts supplier, evidently I have something called an aftermarket 'speedy seal' cover. That explains why the bolts were knurled and not hex head. They come off by hand. There are some markings on the cover, so maybe I can find a new o-ring for it.

 

[Ron20324]

It's a Racor 110. It's on alot of OEM applications, as it's about the smallest filter you can get. I have a Y 3YM20. See West. The nut towards the camera is to drain the bowl. Then the nut in the center of the bowl is cast as a part of the bowl. Unloosen it, and the whole bowl will turn and spin off. Put on a new gasket while your doing it. I have a 120 i'm about to use to replace the 110.

 

[Justin_NSA]

Excellent ! Thanks Ron! I don't know when it was replaced last. I just bought the boat last Fall. I'll see how dirty it is and decide if it's adequate or not. I only motor out of the cove a few hundred yards and back when we sail. Not a lot of time on the engine. It definitely needs a new gasket.

 

[Justin_NSA]

Found a new R11T filter cartridge filter with o-ring and gasket on Ebay for $23.60 shipped.
Still need to find out more about the 'speedy seal' water pump cover with knurled bolts. I'm not sure what the advantage is. I still had to take the pump off to change out the impeller.
Not sure if any of this will help anyone else reading my thread.

 

[Mark Maulden]

The advantage of the speedi seal is the knurled bolts and o-ring. If yor Johnson pump was like mine, it had brass screws going into a bronze housing with a thin paper gasket. PITA putting the cover back on and the gasket would end up leaking after a year...two of my brass bolts disintegrated. Either a poor design or a PO bad decision. They have a website and you can learn all about them. Should probly order some spare O-rings.

 

[Justin_NSA]

Thanks Mark. Found the site. Sent an email to see if I can get some o-rings

Pardon my rambling. Someone may be able to take something worthwhile away from all of this;
I replaced my primary RACOR filter this weekend. A tad messy, but first, the old filter element was almost black, not paper colored like the new one or even slightly discolored like the secondary filter element. I realize that diesels are dirty, I used to own a Mercedes diesel. But this is on the raw fuel supply side, I wouldn't think it should get this dark. I'm just trying to gauge how often I should consider replacing it.
As for changing it; the 2 plugs on the bottom (see previous pic post) are drains. The hex head on top is the one that drops the bowl. Be aware that all of the fuel in the line from the tank will drain out. At least the line comes from the top of the tank and not the bottom! A gate valve before the filter would control some of the drainage.

If you're primary fuel filter is black, you have some kind of crud in the tank. And/or it hasn't been changed in a really long time. If your fuel is clean, your filter should be too.
Start with cleaning the tank.
