Does the vacuum advance mechanism slide straight out of the distributor body after removal of the set screw? no tricks, no twist or anything? (obviously I have to disconnect the actuator arm from the distributor plate)
It's distributor day in the warm shop with wind and ice outside - I've removed the distributor from my new-to-me 4500 - filthy inside and out, no grommet where the wire enters the body, no dust cover -
The vacuum advance is stuck in the body - I've removed the set screw and put some penetrating oil at the appropriate points, from reading here I understand the unit is not longer serviced so I want to be very careful, but unless I get it out of the distributor body I can't remove the points plate and access the centrifugal advance to clean and lube -
thanks - David

Tom in TN helped me find an advance for a 2000, and your part looks similar. Here was his post:

"The place I got mine is called All-States Ag Parts. They seem to be a clearing house for parts with contacts in many different companies.

They actually hooked me up with Wisconsin Tractor in Black Creek, Wisconsin. The guy I dealt with is Mike Like. His toll free phone number is 1-877-530-2010.

Good luck,

Tom in TN"

Hope this helps. Mine worked really well, and they were most helpful.

It has been quite awhile since I worked on a distributor that was that bad. Your work is looking pretty good!

so - got the distributor kinda done - I'm going to post some pictures to maybe help another person with what you see -
I have never worked on a tractor so completely encased in this thickness of yuk - I spent two sessions pressure washing the machine before bringing it into the shop for repair - I didn't spray real hard around the distributor and it shows - I disconnect the vacuum advance line and pull the cap and take a picture of which way it's pointing - third party image

take a picture of the clamp mechanism, or 'arm' as the parts catalog names it - so I can things back about where they were - after removing the set screw, I finally got the vacuum advance mechanism off - there's an O-ring that seals the bore, it was tight - third party image

nasty dirty - and you can see an extra piece half-submerged in the muck -
third party image

here's all the pieces back from the parts washer - couple of extra fasteners lost to the bottom over the years -

third party image

the centrifugal advance mechanism - the top of the shaft is a lubrication point that needs a drop of oil each point change - third party image

the points plate is held in by the screw that hold the cap clips - third party image

vacuum advance re-installed with attachment to the breaker plate shown -
third party image

I got the tune-up kit from the dealer - maybe the quality is good....
third party image

points/condensor with gap set - temporary wire while I find a grommet and maybe some better terminals third party image

Today's Featured Article - Antique Tractor Wiring Basics - by Curtis von Fange. One of the most neglected parts of old tractors is the wiring. After sitting in the elements for half a century or more much equipment wiring has deteriorated to sparsely covered strands of copper or other metal. Plastic insulation has cracked, mice have eaten through the older clothed style coverings and the exposed wires have reacted to winter moisture and salts by turning blue and powdery. Terminal ends have corroded, rusted or just plain evaporated away. Aged wires not only keep an engin ... [Read Article]
