(='_'=) Posted November 9, 2015 Posted November 9, 2015 hey, i am trying to replace the carbon brushes on my starter, but im having problems because the springs raise them out of their place and i cant install the lower section onto the starter body.... do you have any tip of how to do it?? i know how they should go, but i cant make them to stay on their place.... dont know if that matters but its a Johnson 150 from 1994.... i guess most starters are about the same though.... thank you!!

Super User Way2slow Posted November 9, 2015 Super User Posted November 9, 2015 you need to buy or make the tool, that holds them in place while you put the back on it. Quote
(='_'=) Posted November 9, 2015 Author Posted November 9, 2015 thanx, do you happen to know how is it called, or have a picture or something?? i was thinking about maing something out of a thin plastic sheet, like a credit card material, but if it already exists, it would give me a better idea of how to do it....

Super User Way2slow Posted November 9, 2015 Super User Posted November 9, 2015 Not sure what it's called, It's just a thin, flat piece of steel the width of the starter with a notch in the center so it will slide past the armature to the edge of the starter. The one made for it is bent so it actually clips onto the back of the starter but for a one time thing, I would just notch me a piece of thin, flat metal deep enough for it to slide all the way past the housing and just hold it while slide the back onto the shaft. Then just slide it out when the housing is all the way down. Quote
(='_'=) Posted November 9, 2015 Author Posted November 9, 2015 thanx!! more or less what i was thinking, i was going to use thin plastic but i guess ill look for some thin metal then... Quote

(='_'=) Posted November 10, 2015 Author Posted November 10, 2015 thanx!! i managed to install them yesterday using 2 old ID cards to hold them in place while my friend assembled the housing and the lower lid... Quote
Super User Fishing Rhino Posted November 10, 2015 Super User Posted November 10, 2015 Glad you got it resolved. Quote
(='_'=) Posted November 11, 2015 Author Posted November 11, 2015 well, today i tested the starter without intalling in on the motor.... it spins as it should, and it goes up, but it doesnt goes down... mine is a little different than the one in the video, the uppermost part is the small gear, the one on the video has a spring and a nut above the gear but mine doesnt have that.... i know its working, so i installed it on the motor now... i guess ill have to test it out on the lake (i dont have ear muffs), so, what do you think will it work?? will it go down once the motor starts?? thanx!!

Super User Fishing Rhino Posted November 11, 2015 Super User Posted November 11, 2015 I believe on some starters, when the engine starts, it "drives" the starter gear back down the shaft. Don't make book on that. You'll know once you start your motor. You may want to put some light lube on it, or maybe just a silicone spray. Grease attracts dust and dirt and can get "gunky" and make for a sticky pinion gear. Quote
(='_'=) Posted November 11, 2015 Author Posted November 11, 2015 thanx, thats what i believed as well, the motor would "push" the gear down when it starts... i guess ill have to head out to the lake to verify... Quote
Super User Way2slow Posted November 12, 2015 Super User Posted November 12, 2015 If you have it together right, their should be the bendix, with the gear away from the starter, a spring, retainer and nut. When you engage the starter, the sudden motion kicks the bendix up into the ring gear on the flywheel. The spring is to keep it from hitting so hard and also assist in getting it to disengage when you stop cranking it. If the bendix is not going up when you engage the starter, you may have the cables backwards and spinning the starter backwards. Quote
Catch 22 Posted November 12, 2015 Posted November 12, 2015 I manage the brushes with two knife blades. That tool looks handy. Quote

Super User Way2slow Posted November 12, 2015 Super User Posted November 12, 2015 OK, yours is the reduction gear starter that has the Bendix on a separate shaft and your starter just drives a small gear that drives the Bendix. It's not uncommon for the Bendix to stay in the flywheel when you quit cranking on one and it hasn't started. As mentioned, as soon as the flywheel is spinning faster than the starter, it should spin the Bendix out of it. Quote
(='_'=) Posted November 12, 2015 Author Posted November 12, 2015 thanx! then everything is working as it should i guess, now ill have to take it to the lake for the final test.... Quote
