loose air intake temp flap

richmccolman · Post by **richmccolman** » Wed Oct 31, 2012 4:23 pm

Hi guys - the rubber air intake temperature control flap on my air cleaner is loose to the point that I can set the flap for the cold-weather position (needed now that it's getting colder here in NC), but within a couple of minutes of vibration with the engine running, the flap will flop open to the warm-weather position. It looks like, over time, the rubber flap may have contracted just enough that the portion surrounding the metal temp control lever shaft is no longer a snug fit between the two sides of the sheet-metal intake snoot of the air cleaner.
I'm contemplating eliminating the slack by cutting a slot into one side of a small flat washer and jamming the washer between the flap's pivot (and around the metal handle shaft) on one side and the adjacent side of the intake snoot. Another option, I suppose, would be to squeeze the two sides of the intake snoot together with a large pair of vice grips just enough to re-establish mechanical tension between the snoot and the rubber flap. But before I do either of these things, I wanted to check and see if anyone on the list has dealt with this sort of problem in a better way.
Thanks in advance,
Richard

Or you could replace the missing spring that was suppose to hold between summer/winter.

Oh, wow - thanks a bunch for pointing that out! Indeed there is no spring there. Didn't even realize I was missing a part.
Now I just have to go about finding that spring, or a generic one with similar length & tension. I wonder if anyone has any pointers on a source for one...

Okay, here's what will seem to some like a dumb question:
Does the upper end of the spring attach to the intake air temp control lever where it pivots -- the part of the lever at the rotational axis -- or it is attached further up/out on the lever handle? (I'm trying to figure out whether the spring merely pulls down on the pivoting shaft all the time to bind it a little and keep it from moving due simply to friction, or whether the spring biases the lever toward either one end position of the lever's range of rotation or the other, forcing it to rotate to one extreme of rotation or the other once it's pushed by hand.)
I looked for images that would show where the upper end of the spring attaches, but none were clear and close enough to show this in detail. The parts breakdown is of no real use, of course, because it shows an exploded view, with all the parts separated from each other.
If I had the original spring in hand, I think I'd be able to figure all this out based upon the spring's length and tension characteristics, but I'm actually missing the spring. My thought was to try finding a few generic spring replacements and try them one-at-a-time. But since I don't know for sure where the original spring was supposed to attach to the lever, I'm not sure what length and tension comes close to being correct.
Apologies for my ignorance - guidance would be appreciated!
Thanks,
Richard

The spring will mount or go around the rod just up from the pivot point where it is horizonal. if you look close you can see crimp marks on the shaft to keep it from sliding off that section of rod. If you look at figure 2-62 in the Coupe Maintenance manual you can see a picture that might help. It also shows on page 29 of the Coupe owners manual.

Ahh, yes -- I see now. Thanks for pointing me in the right direction on that. I suspected that those crimps on the lever may have been intended as a retainer for the spring hook, but wasn't sure. This is confirmation.
Now I just have to figure out what sort of spring to use. I may end up having to buy several in a particular length range -- ones with different amounts of tension -- and see what works best.
Thanks again,
Richard

Bought a spring at Lowe's and put it on -- temp control lever/flap works great now.
Thanks for the input!

Rich,what size spring did you get? My car was bought restored but the guy i bought it from disabled the flap so it just 'flaps'.Getting cold here in No.Az.Only drive the car every couple of weeks but i would like it in working order.Thanx,Laurie + 1972 Honda z600 Coupr.

Hi Laurie - The spring I got is 3/8" x 2" x .035". (That's 3/8" diameter, 2" long including the loop-hooks on the ends, with the spring's wire diameter of .035".) The safe working load is 0.94 lbs.
Do you have any Lowe's home improvement stores in your area? (It looks like most of the Lowe's stores in AZ are clustered around Phoenix and Tucson, with one in Prescott and one in Show Low.) If so, you might be able to get the same exact item I did - a two-pack of these springs. If not, and if you can't find a good source of similar springs somewhere else, let me know and I'd be happy to send you the second one out of my two-pack.
Note that the lower attachment point for the spring -- a little tab with a tiny notch that hangs below the opening to the air cleaner intake -- might need to be bent slightly forward or rearward to allow the flap to stay firmly open when opened with the lever and also stay firmly closed when closed with the lever. (You'll see what I mean if this turns out to be an issue for you.) It's simple to bend it to the right position, and will be necessary if the tab had ever gotten bent out of its optimal position at some time in the past, as mine was.

Hi Richard,
Thanks for the spring info.There is a Lowe's about 45 min from me(live sort of in the boonie's).I'll check it out the next time i'm out that way. Might have weather coming our way on friday... not ready for it yet!! I'll keep your post and let you know if i have any probs.Thanx for the offer of your second spring, that's so nice.One thing about Honda Baby Car people is that they are very sharing and giving.
Thank You,Laurie
