Getting ready to tackle servicing my steering knuckles this weekend, I stopped by NAPA on the way home from work yesterday to get a seal puller, grease, etc. High temp in St. Louis was 102F yesterday! I get back in my truck, turn the key, and nothing but a single click.

I was contemplating getting out my lug nut wrench and giving the starter a whack when I decided to try again. Click, pause, and then the starter whirred to life and she fired up.

I had to drive 15 miles to pick my oldest daughter up from volleyball practice, then another 20 miles to meet my wife and the other kids at a scout event. So I ditched the Cruiser at home and took our third car--2007 Camry with a non-functioning A/C--to meet the family.

Fast forward to about 9:30 PM. We are home, kids are in bed, and I am not looking forward to having to drive the Camry tomorrow since it will be even hotter. In a bin of spare parts from my donor engine is another starter. Does it work?

Well, it is crusty and disgusting, but it is an original Toyota starter from 1996 from the donor engine that had about 170K on when it was pulled. I did the FSM electrical tests on it, and passed! I also replaced my fusible link and junction block, which has been on my list, but the starter was clearly failing. It would click, pause about 1 second, and then start spinning. So, how hard is this thing gonna be to replace?

Remember, I've got a rebuilt engine that was installed only about 5 months ago, so nothing should be seized. But, holy s***, there is NO room to work under there! Also, the starter bolts were torqued to WAY more that the FSM-specified 29 lb-ft. I was happy that I have about 12 different 17mm sockets of different depths and a variety of extensions to make different combinations of lengths. The upper bolt was particularly difficult; there was one combination of a socket and extension that was the perfect length to allow my ratchet handle to stick out between the shock tower and the wheel well sheet metal. I had about 5 degrees of movement. Slipping a jack handle over the ratchet handle gave me the leverage I needed to break the bolt loose. Of course, it doesn't help that everything on the driver's underside of the truck is currently coated with birfield grease and gear oil from my leaking axle seal!

Once I got those bolts loose, the replacement was easy. The new (old, crusty) started works great, and starts a lot stonger than the failing one ever did. The failing one that I removed is a Denso-tagged reman. It came off of the blown engine that was orginally in the truck. I'm not sure if it was installed because the original starter failed, or as preventative maintenance, or what. But it looks pretty new. I guess there's truth that the remans aren't as good as the Toyota originals.

I finally wrapped up about midnight, once I got my greasy tools cleaned and put away. I'm thankful that I was able to do it in my garage and not is some parking lot!

I suppose I'll tear it down and replace the solenoid contacts (and maybe brushes) and have a spare, assuming the bearings and commutator look good.
 
With the right tools :) it's a pretty easy job (usually). Glad you're back up and running and with A/C. CA bay area weather doesn't often need A/C, though we have other issues being in CA :bang:

I've done it a few times over the years. Our 80 has been with us when bought new late '97. The last few times just using a 3/8" ratchet + extension + wobble for the front bolt and a loooong extension for the rear.


cheers,
george.

Awesome link!

An impact with a wobble would have definitely come in handy! I have a 1/2" electric impact, but it it was in the basement and I didn't feel like going inside and getting it.

Its funny, 'cause on the rear facing bolt (the lower one), I found that between it being right above the bellhousing bolt, the rib on the transmission bellhousing, and the transmission tunnel, it was really tight trying to get any ratchet in there. The fact that is was torqued to about 60 lb-ft wasn't helping. The 3/8" wobble was instrumental in getting it re-tightened.

The front facing (upper) bolt was easier, once I found it by feel and then figured out the perfect combination of socket + extension to get the ratchet handle in a position where I could actually turn it!

In spite of the busted knuckles, it beats the starter replacement that we had to do on my wife's '03 Sequoia last month! That bugger was so seized in the block that it took an air chisel to bust it out!
 
Fully rebuilt mine, amazing difference in performance!

Well, the "junkyard" donor lasted exactly one week! The Tuesday after Labor Day, I dropped the kids off at school, dropped my infant son at daycare, and was ready to head downtown for jury duty. At daycare, I get the click-nothing. She started on the second attempt. I was holding my breath every time I started it, and did it a couple more times on Tuesday. I called the local Mr. T and ordered the plunger and two terminal kits in George's link. They were all in stock in Kansas City, so I had them on Wednesday morning.

Thursday, it was rainy, and that wreaked havoc. In fact, I was pretty sure I was going to need a tow from work. But, she started and got me home. So I cracked open the Denso reman and got to replacing the terminals. Luckily, that took less than hour. However, the quality of the Denso reman was TERRIBLE! No insulation paper on the battery lead terminal, and both contacts were cock-eyed in exactly the way the FSM warns NOT to install them. I don't know if it came from Denso that way, or if somebody replaced the contacts in the past, but it was a bad-looking reman, not at all to factory spec. I would humbly suggest that any body buying a reman cracks it open and looks at the work before installing it. Of course, the contacts in mine were badly ablated where the plunger hits and totally beyond FSM minimum spec in terms of thickness.

Having just done a week ago, I was able to get the started replaced in only an hour this time. Working great for now, and I am considering installing the relay/solenoid mod as outlined here for future piece of mind. Seems like this is unnecessary on a starter with good contacts, but might buy a bit of extra life as she ages... we'll see!
 
Glad you got it working.

What company rebuilt your "Denso Reman'd" starter ie: was it a Toyota/Denso Reman with a red/silver label or something else with a faded white paper sticker?

Got a photo?

I didn't get a photo before I put it back in the truck, but it has a silver and red Denso sticker with 280-0169 stamped on it, with a white paper sticker below. It looks identical this one, although I think the number on the white sticker is different.

Thus, I think it was remanufactured by Denso themselves. Of course, some ape could have replaced the contacts previously, between Denso remanfacturing it and now... I'm not sure. I hope that was the case.

It does not have a Toyota sticker or part number on it, though, so it did not come through the Toyota parts channel.

Tackling my starter was the first job that made me feel like "I'm really in this now" -- it was harder than expected due to access. But I wasn't doing it at home so not finishing wasn't an option! The Denso reman from RockAuto has been solid for me going on 7 years.
