If the water pump seal has failed can it lead to the mechanical seal failing , if so what are the likely consequences/signs ?


Not sure what you mean, "mechanical seal". When your water pump starts leaking coolant, the coolant isn't in the cooling system where you need it to be. It can also cause corrosion wherever it touches on the outside of the engine.
The leak will progressively get worse and worse. Eventually, the shaft will snap, and you won't have a water pump anymore. The snapping can cause additional damage.

Why is my transmission fluid leaking around the seal?


If you bought a new axle and seal, it shouldn't leak. Unless they nicked the seal putting the axle. When using a used axle, it needs the rust sanded off before installing. That rust will eat up a seal.

I replaced emerson 1hp pump to my hayward max pump and leaks any ideas all seals replaced


Hi, this is John the Hayward tech. Sounds like the mechanical seal is leaking. If you replace the spring loaded seal the problem could be that it was installed backwards. It is ceramic against carbon. if installed the other way it will leak. Any debris or oils getting on the seal will also cause it to fail Running pump without any water will heat up the seal and cause it to fail.

What causes the oil to leak?


1. Oil generally leaks because of mechanical failures.
To contain oils there needs to be a mechanical seal of some sort. This may be for the sake of argument a rubber ring or a flat strip or gasket seal of an appropriate material or even a propriety sealing agent which can be squeezed from a tube.
Simplistically a jar can be filled with oil and the lid which has a seal in it is placed on top secure enough to stop the contents leaking.
If that jar is connected to other jars by pipes to form a system they too need to have seals inserted where they join the jars so that there there are no leaks.
2. Seal failures can be caused by heat, chemical corrosion and or erosion , mechanical stress such as vibrations or bending or longevity of material properties such as the elasticity depreciating. Finally other causes can be attributed to wrongly fitted or inappropriate types of seals being fitted.

2003 Hyundai Elantra only has 35,000kms on it! Started leaking oil really bad, took it to mechanic, he fixed the engine seal, went and picked it up, leaking oil on the way home, took it back and they tell...


dear friend-your mechanic is not very convincing,did he perhaps use a pirate seal,or incorrect seal,according the km this car is still new,so it is not posssible for crankshaft to be damaged.please get a second oppion,as it might be that the leak is from somewhere else and not the seal in question.

Onga jsp 130 leaks


It is leaking due to a defective mechanical seal. It needs to be replaced. To replace it, is to take the pumpcase
off by taking off the bolts that hold it. Then, take the impeller off to take the mechanical seal behind it. Put the replacement in, and reassemble the pump. Just get in touch with us by e-mail to get more assistance.

Anti freeze driping out of seep hole from the bottom of case


hello
there are two different seals on the water pump. the oil seal and the mechanical seal. the oil seal helps seal out the oil from the trans case. the mechanical seal helps seal the coolant from going into the trans case, and vise versa.
the weep hole is there to help diagnose if either seal is faulting. so if coolant is leaking from the weep hole. the mechanical seal is faulting or if the oil seal is leaking oil will drip from the weep hole.
hope this is of some help. thank you.
