Coming unhinged! Not me - my MC9 battery door - Need more help!

Hi Craig! Have I told you that I really appreciate your expertise?

I'll try to post pix of the finished product.

Thank you

BTW 22 rifle cleaning rod (also used next sized bore larger), pick/hook tool to scrape the worst of the corrosion out of the channel, compressed air, and KY - lots of it - and I was able to slide in the rubber hinge. Success! _almost_ fun. I won't worry about the set screws. Thankfully I cut the hinge about 1/4" too wide. Tomorrow I go to visit my stainless steel guy to get those pesky severed screws out of the frame. Hardest part may have been getting my wife to go into Wal Mart to purchase all that KY.

Kind Regards, Phil

You better hope she don't read this thread, because nobody recommended KY for this project!

I do not remember if I ever tried KY for this but the best stuff I have found is 40 wt oil. I know that it is not good for the rubber but the part that always fails for me is the middle part.

Try using wire pulling lube from Lowes or Home D. olebusman

See - I'm not making this up! Straight from RJ! Hey - it worked great. wire pulling lube also sounds good.

Next I'm going to post pix of the finished project. My friend who did the work had a fulcrom device which really made the door install simple.

Kind Regards, Phil

Phil -

One of the secrets to installing new rubber hinges is to make sure that the tracks are clean! Many busnuts have used .22 rifle cleaning brushes with excellent results.

Dawn dishwashing soap diluted 50/50 in a spray bottle, keeping both the track and the rubber wet as you work it makes the job easier.

KY jelly is another favorite lube for this insertion.

FWIW & HTH. . .

Or what I did was to leave the rubber in and used a $5.00 H.Depot Stainless Steel piano hinge over the outside and screwed it with self-taping screws top and bottom. No lube, no knife, no pick tools, and 10 minutes done. Sorry I was late to the party and yes it seals out water. Put liquid rubber on the back side of the split rubber.

Here is the finished product -

(Dave - I like your solution - it would have saved a lot of time!)

Note the fulcrom setup my friend Larry setup to easily reinstall the door. Nice. He made it a one man job. Big heavy round base, adjustable neck, and roller at the top. It balanced the loose door against the top of the battery bay. Steady enough to line up & drill.

Kind Regards, Phil

Thank you Gary Hatt / BCM!!

It's so helpful to be able to pull up a thread on just about any bus topic and be able to pull up suggestions, experiences, and best ways to do a repair. Even if it is just reminding myself what I did a decade ago.

Yep, the rubber hinge gave out again on the battery door on our MC9. Time to get that rubber hinge replaced - again.

Take care all, Phil
