O-Rings What NOT to GET or DO!!!!!!!!!!!

[JaysGone]

Well guys Im still learning.
I needed to redue the manifold O-rings.
So I got generics for a buck a piece 10 days ago.
Here they are!!!!!!!!!!!!!!!!!!!!


One word folks, and I put them in today REDEYEsssssss
Fast as heck.
I ordered them saturday here today..................

[Hook#3287]

YUCK!

[sandy]

Red Eye sells the right O rings. If you need them in a hurry, find a local hydraulic supplier supplier. Get a #123 in viton or silicone. Never change them again.

[JaysGone]

Considering I live in what I call a pretty well populated area.
The lack of places to buy parts is unbelieveable.
5 auto parts places and all I could get in the right size then and there was the generics.
I knew after maybe 3 or 4 days they were falling apart.
It began popping again and I could see rubber threads starting to show.
Plus brown gunk<fuel> on the manifold.
Using this dammed ethonal doesnt help in the gasoline much.

Some things you just cant plain ahead of time, and try to order.
Even Honda whos prices are ridiculous.
Takes a 4 days to a week.
Took 6 days for my shock bushings at $4.50ish a pop.

Im not really used to having to order small parts for a bike and wait on them.

[Rio Wil]

I'm guessing those orings are too large in cross section and those little feather edges got squeezed off as they were tightened down. Do you know what the size is?

[JaysGone]

I ripped the package but I believe they were 28mm X ?4mm X 3mm.
They were a perfect fit for the groove in the manifold.
I think it was the ethonal or maybe even the Techron I use in my fuel.
Or they were just rubber and the fuel melted them.
Size wasnt an issue.

[Blackduck]

Had just about all O rings I have used feather a bit but not that bad.
More a sign of O ring size than fuel or additives.
Will need to take some measurements off my spare inlets and see how they correspond to the spec's for O ring grooves.
Will to it tomorrow if the work load is not too bad

OEM o rings...

O-RING (2.4X29)
16075-GHB-B70

[JaysGone]

Well guys whatever the were size wise right or so it would seam wrong although smaller then OEM.
They are gone.
Put Redeyes in ;ast night.

Just thought a few might be intrested in what wrong looks like in such a short period of time.

[Rosie]

I also put Redeyes in last night. Easy job less than half hour.

[xman]

Hey Jay and Rosie
I have a new set of Redeye. If i can figure out there's a leek, I'm going to change them. Did you pull one at a time or the whole side? What did you take apart? Did you do anything special to keep them in place as you put it together?

Thanks Tom

[JaysGone]

In my case I loosened the top clamps, dont remove them.
Then 1 manifold at a time loosen the all the 8mm bolts and place them aside.
Put a little upwards pressure with 1 hand up on the carbs.
Just slip the manifold out.
Make sure the surfaces are clean.
Dont let anything drop into the cylinder port. Very important there.
Slip out the old ring wipe the manifold end down.
Making sure its nice and clean, insert the new O-ring.
Nothing needs be on them.
Then push up on the carbs again and with your other hand slide it back in the bottom of the carb.
Do this for all 3 put back the bolts loosly hand tight.
They are supposed to be tightened to 14f/lbs.
But hand tight is tight dont cram them on.
14ft/lbs will feel like they will shear...........
Tighten them up 1 at a time.
They have to go back on the cylinder they came off of.
They are not the same.
Dont forget to tighten the upper clamps back up, again hand tight is fine.
Repeat for the other side.
15-30 minute job.

You might want to remove the spark plug wires but it isnt really needed to do that.
Might just make it easier.

Tools needed:
Clean rag.
1/4 inch rachet, extention with swivel.
8mm socket.
Philips screw driver.
Or just an open end 8mm wrench for everything.
Half a beer job.

[9Ball]

They have to go back on the cylinder they came off of.
They are not the same.

They ARE all the same...no difference.  Some have vacuum caps and some are connected to vacuum lines...only difference.

[JaysGone]

If they are all the same.
Why is it some line up better then others and sometimes the holes dont line up at all??
On mine, only #5 has a vacuum line.
Ive put on 3 different sets of carbs.
The 1st time I did it.
I piled all six manifolds together.
They didnt go back in any particular order.
I had to find the right one for each port.
Then I actually read the manual.
States to number them and replace on the same cylinder they came off of???

[JaysGone]

Aside from what jr said about the manifolds all being the same. As I dont know that to be 100% correct.

From the manual to correct 1 thing I did write.
14ft/lbs is a general rule for 8mm bolts.
BUT.

Intake manifold bolt 9 N.m (0.9 kgf.m, 5.5 Ibf-ft

Further down it says :

Install the intake man~folds onto the cylinder heads and
tighten the bolts.
TORQUE: 9 Ndm (0.9 kgf-rn, 6.5Ibf-ft)

So still hand tight.

So thats 5.5ft/lbs...........hand tight more or less.
Not 14.

[Blackduck]

Honda parts only list 1 number for all 6 inlets so I would have to say they are all the same

[JaysGone]

Even if all the same..........
In a nutshell.
Big F%^ Deal.

If it doesnt matter and all I can say is so what. Big whopping deal.
Is that really worth pointing that out??
If indeed they are all the same???
I dont think so.
The Clymers for all its worth says to number and replace on same port.
I had difficulty just putting # 6 on number 4 and #2 on #5 for example 8 months ago.
I now number them.
I said put it back on the same port it came off of.
Thats bad advice??
Again dont thinks so.

Some here just love to nit pick and must be 100% factual even if it has no real bearing on the poster being right or wrong.

Its not like I had him connecting a manifold to a brake line.............

Just saying.

[9Ball]

It appears that anyone trying to help you be correct is considered "nit picking" and it offends you.

I won't do it again.

[Farther]

Some here just love to nit pick and must be 100% factual even if it has no real bearing on the poster being right or wrong.

I for one appreciate factual information and not misinformation.  The place for misinformation is the General Forum.  But thanks for posting anyway.

JRH.....please don't apologize for trying to add some sanity to the grossly inaccurate information dispensed in this thread. I personally think this thread should be deleted in its entirety so if anyone searches for o ring info they would never get this included.

[xman]

Thanks Jay for spending the time to write the detailed explanation of how you changed these O rings. You felt there was an issue moving them around, and you passed it on. No more no less, thanks. A rule of thumb is to reassamble with the same parts in the same place they came from.

Tom   

[JaysGone]

I dont want to get into this that or the other thing.
Tom asked what I do, and I explained.
The intakes are identical. I never said that they werent.
Their orientation within the boots are not.
You cant take #1 off and put it on #5 without loosening up the bottom band and reorientating the intake so the holes line up.

If you just piled up all 6 intakes with the boots on.
They dont go back on willy nilly with out having to loosen and reorientate all the runners within the danged boots.

Take them off one at a time and replace on the same.
Thats it done, no problems............

I dont need to know any more then that.
Nor does Tom.........

Thats what pushes my buttons here.
Added info that has no bearing on the task asked about.

For anyone who cares.
My bike was desmogged has no vacuum ports at all on the intakes.
They were cleaned up, welded or soldered over and plugged by some other owner.

Delete the whole thread Willow.
I dont really care...................
