I'm going to assume your 7" is like my 9" and say that after you remove the backer pad and expose the spindle you should have access to the gearbox cover that's held in with 4 screws. if you remove those 4 screws and remove the cover you should have the bevel gear exposed.

of course the handle and guard will have to be removed to make it easier.
hold down the spindle lock when unscrewing the backer pad.

The polisher when the switch is depressed will routinely stop then start again by itself. What could cause this to happen? Brushes look like they have alot of life left in them. No loose wires inside...

Its almost without a doubt your brushes or a broken wire inside the cable, Usually a broken wire near where it enters the machine, Some times it can be caused by a dirty switch which will need replacing, does it have an electronic speed control? if so these give a lot of trouble and not worth replacing but it sounds simple enough? Try switching it on and flexing the cable near where it enters the machine, If it works now and again its a break in the cable,Hope this helps,

Gears seem to be skipping. which of the 2 gears is most likely to wear? the one on the armature? or the big disk one?

If one gear is damaged it is causing damaging to the other, whether you can see it or not. If you have teeth that are skipping, the gear with bad teeth will wear out the teeth on the other gear. You should always replace both gears. On your polisher, the small drive gear isn't on the armature, it's part of the armature (Makita part number 515266-4) and that's a $90 to $110 part to replace. The spiral bevel gear (Makita part number 227455-6) is $40 to $45. You can replace one or the other but the gear you leave in will only wear out the new one.

I have been using a Mouse and turned it off for a break. On resuming the job I could not turn it on again. The switch clicked but nothing. I have checked the fuse

Sounds like it could a be switch problem. Unfortunatly I dont think there are replacement switches available for this unit because the cost of service would be would be higher than the replacement cost. If the unit is less than 2 years old it may fall under B&D's 2 year warranty (even if you do not have a recepit there is a datecode stamped on the machine.) You can find a service center though The only question I have is, where you using or had you used the sander to sand drywall? If so, the B&D warranty is voided. Many people try to use electric sanders to sand drywall and as hard as the tool companies work to seal off the tool componant, drywall dust is so fine that it still gets through, gets caked on everything and kills the motor and switch. Unfortunatly the best way to sand drywall is with the good old sanding block.

Milwaukee Polisher model 5460. Gear Case Replacement

you need to remove the pad first and then you will find 2 torx screws about a 25, remove them and the plate next if you have a dead blow hammer tap on the side of the gearcase where the screws were and the spindle assembly and bearings will jump out of the housing, then remove the 4 screws holding the gearcase to the motor housing and it will come apart. To reinsert the spindle assembly gently tap back into place with the hammer to reset the gears. Let me know if you need more assistance.

Old longcase clock oak

As far as the wood I would use mineral spirits. and gently clean. do not use laquer thinners it will remove the finish. after you are satisfied with the cleaning you can use old english to give it a new looking finish. old english takes time to dry sometimes a couple of hours.

Grinding noise,possible clutch

No, it doesnt sound good. These machines don't have clutches but it could be a problem with the gears or gear lock. You shlould really take it back to where you bought it and get it checked under warranty. If you take it apart yourself at all you will invalidate the warranty.
Has anyone engaged the gear lock whilst the disc was still spinning. I see a fair few machines where this has happened and it causes damage to the lock pin, gear and gearbox housing.
