This was a project that seems pretty straight forward......... not so much. I took out the vent and old seal without taking any pictures, so I'll have to just show the install. My youngest gave me a hand the other day and here's what we did:
We started with a clean slate, and then tried to figure out how the gasket went on. We finally settled on this:
Lip on gasket faces down
Got the thing in with not much trouble, unfortunately it was only a test run.**** taping is a good idea****
Tore it back out to clean prime and paint the rusty parts only
***The bolt assembly must be taken out in order to get it in or out**** I took it apart a while ago and thought I should figure out how the bolt goes back in while I'm not standing on my head.
Next time I'll take pictures BEFORE I take it apart!
Hopefully these will help you if you're in the same boat I was in
I've seen where guys will take it out from the top, but I have nothing in the cab to stop me from doing it from the bottom, and it worked well. I did leave the radio bracket in though with no issues.
Both removing and installing I start with the passenger side first. Push it up through and start wiggling the other side in. L0ts of wiggling and moving the level all the way back and forward (that's why you take out the bolt)
My boy is now helping and holding it so I can take a photo. Notice NO gasket on yet. You'll ruin it if it's installed right now.
My helper is still holding it up, but now it's to help me access the gasket. I did accomplish it the first time alone, so it is possible to install the gasket alone, but easier this way.
I did not use any sealer or adhesive.
While installing the screws I would pry the gasket toward the assembly so it was tight.
Then I would poke a hole for the screw to go though
All screwed in
Reinstalling the bolt assembly
As Ross has mentioned in a few other similar threads, do not lubricate moving parts that are still workable as they may not hold enough tension to keep it down while driving.
Lots of rust in there so I filled it with WD40 and let it run all over inside.
The 4 bolts underneath do not need to be removed all the way. Just loosen them a bit and slide it towards the passenger side and lift out for removal. Reverse for install.
Thanks for the great step-by-step photos and narrative. I'm getting ready to re-assemble my C600 and you will have saved me hours of swearing and throwing tools.
I made the mistake of not taking pics when I did mine, after a few years, two gaskets and several tries I got mine to work properly. "LOL" Keep up the tutorials. I always enjoy seeing what and how folks accomplish each task.
I have to save those pics, perfect timing as I will be doing the vent seal soon. I havent gotten my vent unit out, looks like I can leave it in place and loose to install the new seal.
Thanks so much for the pics and tutorial. I'm in the middle of doing mine right now (blasting and painting), and I didn't take pics of that lever adjusting bolt. You're a lifesaver.
Just did this a couple of weeks ago to my '51. Your tutorial is right on. One thing I learned is to not over-tighten the bolt that holds the thing open. It will work OK if too tight, but will chew up the area that the washer slides over. A little lithium grease and spending some time opening and closing will yield the correct amount necessary to tighten everything without damaging the sliding parts.
Many thanks for documenting this at the time SERE, I realize that this is an older thread, but I found it and was able to install my cowl gasket without too much pain today. I just wanted to bring it to top at the forum and add my thanks.
