CAT 988A Information

[Arnauld K]

Dumb question but have you tried running and using this machine yet before doing maintenance? Why was it parked it may have problems.

Your question is not dumb Sir. According to the previous owner, The machine was parked for so long because the engine was broken down and he decided not to repair it because, since he was living in france , the one he appointed to drive and manage the machine was receiving money from customers but was using that money for himself without informing him. So the owner decided not to rebuilt the engine because it was mainly the driver that was benefiting from that machine. That’s how after about 10 years, I enquired about that machine to know if it was for sale, and he agreed to sale it to me. So I never tried running and using the machine before , but I met the man that used to be the driver of the machine , and he told me it was working and running very well before the engine failure .

Arnauld. This man who ran the loader is a thief and a lier. You can’t trust anything he says.

Yeah what you say makes sense. And I don’t intend to have him as a driver. There are so many 966c drivers here I will get one among them as driver. And since we’ve rebuilt the engine i keep hope that everything will be alright.

Ahhh, that's not good news, and it means you're going to be looking at a serious expense for a complete new water pump.

Possibly the best source will be CGR Ghinassi, the Italian aftermarket parts manufacturer. If you contact them, they will be able to advise how to acquire one of their pumps, and at what cost.

It will almost certainly cost you many hundreds of dollars to acquire a complete new water pump, as they are a big pump, they're heavy, and they are now hard to find, either new or used.

Hello , I finally ordered a water pump (2s7209) . It was delivered to me and I was so disappointed when I opened the box and saw it; it was not complete... see on the picture attached how it came. There is no way we can fix mount it on the engine . So I will need a cover with some Elbow for this pump, according to the part manual . You can see on the second pic I took from the service manual how the complete water pump looks like. I don’t just know what to do about this wheel loader ...

 

[OzDozer]

What you describe as a "complete water pump" is the water pump with associated piping housings. If those other housings are missing, then you will need to purchase them, too.

What was delivered to you is a replacement water pump, which is the same that any parts supplier, including Cat, would deliver.

 

[Welder Dave]

Having a parts diagram really helps especially on a machine that is missing some things. In the case of Cat a lot of things are seperate and not included. Even the rubber gasket that goes around gauges is seperate.

So sad to hear that... too much spending . Thanks anyway , I will see if I ca find a similar used water pump

I have a part manual , I don’t know if it’s the same as part a diagram, but it’s only after receiving the pump that I saw in the part manual that there are some element of that pump that come seperately ... I just bought the part manual few weeks ago, so I’m not really familiar with it .

I tried looking on SIS and see your pump but could not copy a full picture for some reason to past it here. If you need the part numbers of the two elbows and any other part let me know and I can look them up.

The page in the parts book shows the whole pump assembly but many of the parts have a black triangle next to the part number and a note at the bottom of page saying not included with pump assembly. So You have to be careful when ordering parts.

Yeah you are right. It’s only after the pump was delivered to me , that I realized that , in the book part , it was mentioned that the parts with a triangle next to the references are not included with the pump. Since I’m not yet very familiar with the book part I don’t pay attention to some details... thanks for your help. I have all the references , there is as shop in the US that has most of those part, they will cost me about $1600 with shipping to an US adress included. It’s quite out of my budget for the moment. I also learned that there are about 9 CAT machines using that same water pump. So we are trying to Find out if there could be one of those machines around us that are no loger operationals so we can buy the water pump (even broken down) from the owner at an affordable price .

Thanks for this links Sir.
Other very important parts needed for that pump are :
- Housing 9M2413
- cover 5H2830
- Pulley 9M2411

There is another part 9M2408 called bracket . I saw it in the document on the web as a related item to that pump. I wonder what it is , wish I can know if I can do without it .

Can those elbows be fabricated by a local welder?

 

[Arnauld K]

Can those elbows be fabricated by a local welder?

Yeah, sure. But the welder might need a sample to do that . As he will also need to fabricate a housing and a cover and we have no idea of the shapes. The welder I work with, fabricated the exhaust Elbow for the turbo.

Is this what the pump should look like (with an additional front elbow)?

even better:

Yeah! Exactly

 

[kshansen]

Hope they didn't run it any longer than that with no water in it! And the least they could have done is had a hose on the return fitting from the fuel pump! But maybe they spent all their money on the nice thick coat of paint!

 

[OzDozer]

I really am amazed at the number of YooToob idiots running engines for multiple minutes with no coolant in them!!

My training was that any engine run for more than 30 seconds without coolant is irrepairably damaged!

Hello, Great news for me guys. I contacted some CAT mechanics I know and I shared with them my urgent need of water pump. So I gave them the List of CAT machines using that pump (988, 825B, 826B, 768B, 769, 769B, 824B, 834, 657, 657B).
one of them called me telling me that he knows a 825B he used to work on and it’s no longer operational . So he contacted the owner who agreed to sell me the complete water pump at $275...

Fantastic! I'm sure here in the USA there are many of those engines just sitting in scrap yards but probably not many in Cameroon. Now that I think of it I know where I have seen a 769 Cat truck parked for years that I believe has that same basic engine. Once you get the "new" pump I'd hide it good so you don't have this problem again! And if you can post a short video of this machine running.
