Boomer 3045 Water Pump - Overheating

[ptsg]

Messicks lists a reman water pump for $178 or a new water pump for $324. A new alternator was around $530 if I recall correctly. They offer reman options a lot cheaper as well.

dang that's quite a bit cheaper. The part number doesn't match although it does look like it is correct.

Quick edit. The 3045 version is 70 amps while the TC45 is 40 amps.

I have a bit of issues with Chinese made stuff but pretty much whatever you buy most likely is re-branded stuff but yet same origin. I would never buy a Chinese tractor but components I would buy. Just an example I lost a compressor for Honda Vehicle. The OEM Honda was $1500 and some change. I bought a Fleabay compressor from China for $120. Put it on, evacuated, charged and have Ice cold discharge Temp @ 46 to 48 for the last 3 years. It already paid for itself.

PS, The casting looked good and was perfect facsimile of OEM. Just wondered OEM also cam from the same factory re-branded.

Bet it's less expensive to get it rebuilt. In reality there is little inside to fail. The diode trio or the exciter brushes or the shaft bearings, all easily renewed.

That is perfectly correct as 9 out of 10, at least American cars I owned needed diode trio to rectify the current. it was so easy to change and as long as the bearings were good then diode costed about $3.50. I doubt it is that low price now. By the way did a quick search and O'Reilly sells it for $7.29.

Tell you a short story about Chinese made tools... I bought a Harbor Freight Chief 4.5" air powered angle grinder ($105 clams). I also have the Ingersoll Rand 4.5" air grinder ($270 clams) from MSC. if you put them side by side on a table, you cannot tell the difference between the two unless you look at the side.. One has 'Chief' painted on the side, the other has 'Ingersoll Rand' on the side.

Why do I think they were both made in the same Chinese factory on the same production line but final assembly with the branded handle was the only difference (besides the price of course.

Another look alike is the ICON 1/2" drive clicker torque wrench, 110 bucks at HF versus the Snap On 1/2" drive clicker from the tool truck at a tad over 500 bucks. Put them side by side on a table, no difference but the lazer etched name on the barrel. Same tool exactly and same accuracy. Needless to say unlike the 4.5" IR angle grinder I own along with the Chief, I don't have a Snap On torque wrench but my buddy does so I got to compare them.

Not that way always but I thought you might enjoy those 2 examples.

I suspect a ton of stuff comes from over there and gets rebranded or repackaged and the price goes up as well.

Don't mind a company like Snap On or IR making a profit but making a profit and gouging the end user is 2 different things.

Why I always shop around and compare stuff and watch YT vids and ask friends. I work hard for my money and I don't want to pizz it away for no reason.

I do know that some Chineseum water pumps have a fitment issue. Cannot speak for alternators as I always get mine rebuilt if possible.

Totally agree with what you say. Chinese manufacture everything for anyone. what matters the specs they are given and negotiated price. They can make a wrench out of pot metal of best SS or Chrom vanadium. One might be $1 and the better one might be $10. just look at a prime example apple and their manufacturing in China. Now on alternators, the only alternator I have overhauled several times was AC-Delco on my Buick Skyark and chevy Chevette while in college. I have never had so far a Toshiba or Japaneses made Alternator to fail out of our fleet of 5 hondas.

Sharing my understanding of alternators. And apology for sidetracking.
Alternators are a science onto themselves. And no, they are not all the same.
Yes, figment and rated output are key data points. But alternator manufacturers play a rating game. Output specs should be considered at temperature and rated pulley RPM, self-excited output, etc. Consumet beware.

Yes, in a past career, I was tasked to specify and engineer alternators for an OEM of transportation vehicles.

But for most DIY replacement, fitment and “nominal” output will suffice.

I hope you were better and that than you are at spelling.....

I took a better look today and here is what I found. The coolant level was a tad low which I didn't notice yesterday as it may have still been warm when I looked. I'll run it again today to see if the overheating was caused by this. I also did a better job of cleaning the radiator fins with a hose as suggested above. I usually blast it with my compressor every few hours.

The noise on startup isn't the belt or the water pump after all; it's the alternator. If I slowly rotate it by hand, it remains silent. However, if I spin it really fast, it screams like a banshee. I guess the bearings are going on it.

Taking a look at mycnhistore, the alternator is priced at just over 1500 CAD$! And a suitable aftermarket doesn't appear to be available from the usual online source or are just as expensive.I'm going to take it to a rebuilder unless someone has a online source for a new/reman.

fyi - The tractor has 3450 hours. I purchased it at 2700 hours 2 years ago. It had a rough previous life although it was well maintained in a fleet for snow removal. It now serves as my snowblower/land clearing/wood hauler/sawmill forklift.

thanks again

$1500 for an alternator has to be for a case of 8 of them. Absurd. If you can sort out the wiring issues most likely there are dozens of other alternators that would work just fine. Back to the overheating: Esp with that many hours you may want to check the radiator cap too. If it is weak and won't hold normal pressure that will cause overheating (which it did on a Kubota I was working on.) All that said, you probably have a dying water pump.

exactly, below some info I cataloged for my rig many years ago,



Let's say Kansas is 800 feet above sea level with atmospheric pressure of 14.1 rather than 14.7 psia

At sea level and 14.7 psi atmospheric water boils at 212 deg F

7 psi radiator cap=14.1+7= 21.1 and water boils at temp of 230 deg F

13 psi radiator cap=14.1+13= 27.1 and water boils at temp of 243 deg F



50/50 anti freeze raises the boiling temp to 223 @ atmospheric condition and up to 275 deg F.

so a tight cap and radiator increases the boiling point. At boiling point change of state happens from liquid to vapor.

Radiator caps are another neglected item that really needs replaced every few years. The seal gets hard and the spring gets weak. They don't last forever.
