Starter Issue

[CostaRicaPrado]

Hello,
2000 w/4.7L.
History of vehicle is unknown.
Starter is making a raspy, screach sound during start-up. (Its not the belt).
The starter engages as soon as key is turned and the raspy noise stops as soon as the key is allowed to return to ON.
(Does this eliminate the contacts as the primary issue?)

It sounds more like a Pinion Gear. Is this a common failure with these engines?

What starter supplier do you suggest for replacement? Are you having good life from Remans?
Thankyou

Did I post this in the wrong sub-forum?
Thanks

Nope, not the wrong sub-forum. Probably just people not wanting another starter thread - there are a lot of them.

Bad contacts usually result in slow-crank, intermittent no-crank (click, click), stuff like that. Your noise could be the gear not engaging the flywheel. You never mentioned if the engine actually starts while this screeching noise is going on. There also have been issues where a bearing retainer ring on the bracket side of the starter pops out and makes all sorts of grinding/squealing noises when the starter is cranking. That can only be seen with the starter removed.

Either way, it sounds like you will need to pull the starter. Most people here rebuild earlier MY 100 starters and replace later MY 100 starters. Here is some info here: Procedure for replacing 100 series(98 and up) starter contacts

Also, I know there are a couple of walkthroughs on intake manifold removal on here, but I can't find them at the moment. Search for either starter replacement or knock sensor.

I did the starter replacement one week ago.
I had to laught at Vermont's avatar photo.
It's a little bit PITA, yet nothing you can't tackle.

As an aside: I cut a 2x6 the width of the inner fenders, and placed that inside the engine bay.
I sat and/or rested my chest on it while working the starters out/in. Much recommended.

Yup. I couldn't even begin to lift the manifold without being up in there...

@Vermont,
Great info. Yes, I had searched before posting and found good removal threads but mostly diagnosis for Contacts being worn.

Plus, vendor lists and reputable rebuilders changes over time so I like to get up-to-date experiences. I belong to a number of motorhead forums and I never get tired of answering posts no matter how many times they are asked. The good forums and the good members understand that is what forums and community are all about. Thank you for stepping up.

Also, your post on Early & Late MY quality is just the info I needed as I gather info on new vs rebuilt.

 

[CostaRicaPrado]

Can anyone suggest a reputable seller of rebuilt starters?

Were the original starters the DENSO? Does anyone have a photo of their factory starter? I need to see if the one in here now is original or a replacement.

Thanks

I don't have any good photos, but mine has a silver/lime green tag that has TOYOTA on the top, and DENSO on the bottom. It's factory as far as I know.

Thankyou.

Be careful not to damage any of your sensors when removing or installing the intake.

Denso's are good.

Pulling the hood makes things much easier.

Great photos.
I can’t believe thats the location of the starter on the 100. My 40’s were designed for accessible field repairs.

I was shocked too, however being moved away from the exhaust and up into that spot allows the starter to not experience as much heat soak and they tend to last much longer. Mine needed to have the contacts and plunger replaced at 300k miles. Not too bad. It isn't easily serviced but Mr. Toyota figured out how to make them run a LONG time by popping them up there.

This is one of the few times that Mr Toyota should have looked at American V-8 design. Pull 2-3 bolts and the starter drops in your lap.

And replace them all the time.

I dunno, the starter on my 80 series is down there....and I've replaced the contacts in it exactly once. Original starter, 310K miles on it. I know the mileage doesn't equate to 'starts' but suffice to say...its lasted a long time.

Conversely, had to replace the starter on my 100 series at 185K, not much fun. On top of that....the alternator on the 100 series is right down there in the rain, dirt, dust, salt, etc....not the best spot for it.

I love my 100...but those are not my favorite features.
