I assume an mc7 door is supposed to latch(overcenter) by pushing it shut from the outside. I still have the closing arm attached and have tried adjusting it. It's adjusted so the door is tight when closed. Could something be missing? Or perhaps sprung hinges? Roger | ||

Rodger, I have the same problem and have not been able to figure it out. I replaced the spring that is located behind the panel on the front of the bus between the windshield wipers. It helps keep the door open and closed. I got the spring frome luke. I have come to the conclusion that My door is sprung or adjusted improperly. I have read the manual and talked to various experts. If You figure it out please help Me to correct Mine. It spring open with a press on the button on the front of the bus and be able to be closed fron the outside. Mine is difficult to close with the handle inside and impossible to slam closed fron the outside. Good luck and please let Me know how You make out. John | ||

Roger & John - IIRC, there's a turnbuckle inside the dash on the rod between the door handle and the door. Access is thru the fire extinguisher area. Sorry, don't remember which way you turn the buckle to do what, but that's the adjustment for the closing mechanism. I think the procedure is outlined in the shop manual, too. Do you both have your door air lock working? Makes a big difference in front end noise when underway. FWIW & HTH. . .  | ||

RJ, how would I know if the door air lock is working? I have actually wondered about the door air lock. I suppose I could try oopening the door with the engine running. Do You have to be in gear or anything? Sorry for the ignorance, but this door has been a pain for a long time. Any help is very much appreciated. Thanks, john. | ||

should be a handle by your right knee that works the air lock on the entry door | ||

My air lock works well. It pulls the door tighter than the handle. I have adjusted the turnbuckle, but if it's loose enough to close the door, a small kid could almost get in!(not to mention bugs etc.) | ||

There is a momentary switch under the dash that activates an air solonoid in the spare tire compartment that should automatically operate the door latch air cylinder. On my MCI 7, this solonoid was dead and blocked air to the cylinder. I bypassed it and now just use the red knobbed lever under the dash to close it for travelling down the road. I did not have an RV handle, just a Schlage deadbold that would not keep the door closed underway. My door closing equipment (handle,etc,)had been removed by the previous owner. I added a handle to pull the door closed from the inside and I throw the deadbolt and then when the air is up, throw the red knobbed lever and I'm good to go. I installed my door and it took a long time to get it to close properly. I found that the bottom step had been bent up, so I took a 6x6 log and a sledge hammer and fixed it. Also be aware that between 1968 and 1972, they changed the door latch cylinder and catch and hinges. I had to drill and tap new holes for the door and catch. Good Luck! Glenn | ||

Roger and John, we have pretty much the same thing with the GMs. When we visited Ted Campbell in Williams, I asked him about the door adjustment. He said that it can be adjusted so that it can be locked by slamming the door or it can be adjusted tight enough that it won't whistle, but not both. We chose to make ours fairly easy to lock, and now I need to find some combination that will reduce the air leakage. Perhaps that is what is happening to you. If it is, then I can see why MCI has the door latch cylinder. For what it's worth. Tom Caffrey PD4106-2576 Suncatcher Ketchikan, Alaska | ||

I found a remedy for air leaking and that was to put a small J rail in front of the door and that will deflect the wind/noise from coming in around and it works and doesn't look bad at all, but use the small j rail not the large J LOL Gomer Oh btw, Install it up and down right at the edge. LOL | ||

Doug, would you care to elaborate regarding your doors? Are you saying that they never needed adjustment or just that they were easy to do? Thanks. Tom Caffrey PD4106-2576 Suncatcher Ketchikan, Alaska | ||

we have never needed to adjust any of the doors on GM's we have owned 2-4104's 4107 4903 2- 4108's 4905 wind noise generally comes from a front door seal that is gone or broken | ||

Thanks, Doug. From what you are saying, I expect that our door has been damaged and not repaired right. Am I to take it that you don't think much of Ted Campbell's opinion, as well? Tom Caffrey PD4106-2576 Suncatcher Ketchikan, Alaska | ||

Doug, I have a red lever by My right knee, but if the bus is still rigged as new the operators manual says that the red lever is to dump air to the door latch cylinder in a emergency. It is supposed to lock when You use the manual door closer but if it is I can not tell it. I am about to give up and live with it until I can get to a rally where maybe someone can help Me with it. Regards,John | ||

John - When you push the red lever forward, you disable the air door latch mechanism. When you pull the lever back, the latch mechanism is supposed to work when you close the door with the handle, which contacts a switch under the dash. Won't work with the ignition off, btw. Easiest way to check to see if it's working is as follows: From the driver's seat, close & lock the front door using the door handle with the engine running and full air pressure in the system. Then move the red handle forward & back, and listen to see if the door latch activates and/or releases. If it does, great. . . one less thing to fix. If it doesn't, time to get out the shop manual! FWIW & HTH. . . | ||

Thanks RJ, I will give it a try when the better half gets home from work. What You have said makes a light come on in My old tired brain. I will post after I try it. John | ||

Thanks RJ, after the bus had the air up I closed the door and pulled the lever back and low and behold I could see the door pulled in at the trailing edge. If the lever is left back and the brake is released, engine running when the door is closed the latch works all by its self. The operators manual does not explain the lever operation in a way that indicates that the lever should be left in the rear position. Thanks so much for the final clue. Great to have so much input. Thankls again. John |
