3 cylinder distributor R&R

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
 
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 -

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 -

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

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

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

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

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

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

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

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.
