Need help!! Found the leak!!

[yamabro]

A friend of mine has got a leak in the front end hopefully his wont be the third one with the same problem. Good luck with the fix

Sorry to put a damper on your professors info. Hope it doesn't dampen your eyes.

this has been the week for wheel bearings and balancers apparently. Lord knows what it will be next week.

Obviously, the Professor didn't read the tech manual.

I wonder if he used "Search".

So dampener it is! LOL!!

I think I am going to call it that POS on the crank!

Hopefully not!! If it is though it is really not to bad to fix. Just takes some time to get everything disassembled.

The 361 series TM calls it,

5 PBFZZ 19207 10935278 PULLEY AND DAMPENER

I was so sure you would quote the TM I didn't even look up what the TM called it. Just waited!! thanks

It would seem to me that Harmonic balancer and vibration dampener would mean about the same thing. But was wondering what the TM called it.
At work we actually use both names for the same part. Is strange 2 in a week. Usually things come in 3's.

no way of telling , could have been anything . but beerslayer had it right , a w.a.g. , so ill add mine , without a microscopic inspection of course without magnafluxing the broken partss , there is no way to tell. , could of been some soldier could of left the damper loose allowing the harmonic engine vibrations to crack the damper at the weakest part @ the keyway eventually breaking the piece in two. .option two could of over torqued the damper causing the same failure. option three during over haul soldier two dropped the engine on the damper and seeing no visable damage said nothing . you get the idea ?? oh and never forget the built by the lowest bidder option . interesting

Did you replace the seal in the timing cover, it was hard to tell by the picture if it was 'tweaked, torn or twisted' by the broken edges going round and round inside of it.

 

[jwaller]

I had the damper go bad on mine last year. there is a thread on here with pics somewhere. I replaced it pretty easliy.

 

[deuceaid]

now that I think of it, how could that drive pulley dampen or balance anything? It doesnt have the mass of the flywheel, and I dont see that it has been milled to offset some other weight. The last option would be an active dampener, but You would hear the loose material or fluid moving around inside it... its a pulley Jason Phd BS

I am going to replace it when I go to put it back together. I tore the truck apart to replace the timing seal and gasket because of a leak and found this.

check your key in the keyway mine was broke in half...... after this we might become dampener friends

I checked the key and look to still be in one piece!

thats good If somthing happens and you need one order from memphis equipment there 4.50 plus shipping... do not use store bought key way most likely its unhardend and you will have problems... did you get your timing cover off?

I have not gotten the cover off yet. How did you get this bolt out without taking the air compressor off? Mine has a nut on the back that I can't seem to get to with a wrench to hold it from turning.

I got mine back together tonight get a stubby and you can get it in there..... Its tricky getting the washer and nut back on but I did it with my fingers

Maybe the guy that wrote the tech manual wasn't a professor.

 

[doghead]

I don't care if he was the head bait tender on a Grecian tuna boat.

It helps if we can all reference the items as the TMs list them, so we all know what were discussing. We can reference page numbers, pictures, and part numbers with the TMs.

Just to nit pick here - it's a damper not a dampener. Dampers take away vibrations. Dampeners make things wet. Just something one of my professors once told us in class

"damper" is how the engine design texts spell it.
