is this how its supposed to look or what parts do i need? i took the water pump off and this is all there was no bearing nothing just this. i didnt take the innner cover off just the water pump cover. but the schematic shows a whole difference of parts then these pieces,[/b]

anyone? in the schematic there is a washer two seals and a bearing and all there was when i took mine off is this thing with a spring on it.

 

wtf, never seen that before, i never took my pump apart enough to notice this. i just took the outer cover off and let everything else in. maybe i should check it tho, im going on 3 yrs now and i know some people have had pump covers in the past.

this is whats supposed to be in it

 

Its called a mechanicl seal,,, {ha I cant spell it} it looks broken,,, was it driping out the hose at the base of your pump housing ???? they are cheap to replace

 

haha beat me to it pigdog, i just checked it out and its called a mechincal seal it looks to be fine to me but still are pretty cheap

alright the mechanical seal comes with spring and all? couldnt notice from the schematic. i just had a rebuild and had someone put on a new cover but i thought i would notice its been 30 hours. and theres no bearing like it show i shoud just order all that huh.

 

i found it in my service manual, you should go download it out of the engine section its pinned at the top


VERY helpful

 

no need for the manul, im here to the rescue

with my copy and paste skills in Paint :rofl:

fixedit. i forgot to add #12 and 13 before

 

lol yea see #2 mechanical seal

 

umm....I kinda responded to this in the Gasket blown thread above......

but, yes, that is a mechanical seal....and yes, it is damaged.....

you are SUPPOSE to replace this seal by removing the right side case.....knock out the oil seal first...then the mechanical seal (according to Honda this is the prescribed and ONLY method)....then tap in a new mechanical seal...then new oil seal.....




HOWEVER......if your a dumb azz Oakie like myself. and dont know no better.........there is a short cut that works just fine.......


instead of going to the trouble of removing the case.....knocking both seals out from the back side...... then replacing all the seals.....

simply use a screw driver (or in my case a special curved seal removing tool 'used to be a cotter pin remover'..lol)... and you can pull this seal out from the outside with no problems...... then simply tap in another seal....... its quite simple and fast......

but dont tell Honda.... we wouldnt want to do anything 'simple and fast'....lol



and of course.....this is just my oakie way of doing things....... no warranty expressed or implied using the above method...

jmho...me~

 

I know this huge

So i recently Bought a new MX Offroad Supercooler Kit Spectra

So i had issue when getting the stock impeller off. So in the process i must have screwed up the Mechanical seal. Cause when i installed everything back up and poured new coolant it started to come out the bottom

:sweatingbullets:
So i am debating on whether to install it myself or not.

I was looking at this thread and it looks pretty self explanatory. Still not sure. If i take it to a shop almost completely disassembled, how much do you think it will be.
