starter brushes

pinball · May 5, 2022

i replaced the starter brushes on my Delco Remy starter on my int 300 tractor. been 30 years since I've done that. i need some help getting
the brush assembly back on. I'm by myself, hands don't work as good as they used to. maybe someone can give me some tricks to hold those
brushes open so i can get it on. thanks

Are you asking how to get the armature back in?

I just push it gently up against the brushes, then start pushing the brushes out one at a time while holding steady light pressure on the armature.

There is enough slack in the hinge pins that one by one they will hook on the edge of the commutator and eventually all will be in position for it to slide home.

If this is what I'm thinking of you pull the spring to the side and slide the brush beside it, install end plate and use hooked tool to release spring allowing it to rest on top of brush. When all brushes are in place install cover band.

the trick to that is have the brushes pulled out enough so the spring pushes on the side of them instead the top. then once the armature is in u just lift the spring with a pick and push the brush in and set the spring on the top. very easy and fast. i should not be giving my secrets away.

Rustled, please cough up that secret. I can't visualize it.

Tie rap them back , then side cut to release .I usally get it with long thin screw driver ,one at a time with the end plate at an angle pry back against lever against brush spring over commutation, Depends hold the brush on slightly then go to the next repeat .

Been a while since I worked on one with the band and windows in the case. I think you can go about it the same way as the later models the case has no band and the back bearing plate is a heavier stamped flat plate that only holds the bushing but does not support the brushes as the one you have does. Place the assembled nose with drive and armature in a vise so the commutator end is up. Slide the case down on it. Now place the end cap with the brushes on top of it aligned to the wires properly. Now spread the brushes out one at a time to get them to go over the commutator. A couple brushes may need install once the end cap is placed on top due to them connecting to the field leads. One of SVCummins girl friends will show you how to do it near the end of the linked video. Also the method rustred and Leroy are describing is for Ford and some Chrysler style starters that have coiled up flat springs and the the brushes slide in a rectangular receptacle.

I do it like Steve and 560 do it. Slip the brushes back one at a time with it tilted slightly and slips on when they are all on the commutator.

i am referring to the starters like the old fords and my LA case was the same as i did it a couple weeks ago, and thought thats what he had. not visualizing what type he is referring to at the moment. i know the w6 the brushes are mounted right to the spring and i just slip 2 over the armature with the end plate on an angle then slip the other 2 over and done. those are easy. so i presume the 300 is like the w6 , nothing to them either. the ones i am talking about the brushes slide in and that spring holds them down against the armature. guess he should have posted a pic to be on the same page.
