SC 400 Starter Motor Removal
I have a 2000 SC 400, and I am presently attempting to remove my starter motor to replace the contacts. I am trying to remove just the motor itself (rather than the entire mount) in order to replace the contacts in place, as ClubLexus user billydpowe advised in this thread: https://www.clublexus.com/forums/ls-...ml#post6052613 I want it to look like the picture attached. However, when I try to remove the motor, only the case moves - the internal components (brushes, etc.) remain attached to the mount. How do I get the motor - internals included - out in one piece to look like the picture? I have looked through every thread that I could find on this as well as a 1999 Lexus workshop manual, and I cannot find the answer.
Thank you.
Thank you.

Yes, there are two of those, both of which I removed. This enabled me to move the case of the motor, but not the internals.

I have not removed the started on SC, but on GS (the setup seems the same), I removed the starter by undoing the bolts/nut. In the attached pictures the access to the mounting nuts/bolts is from the top, but they come out towards the transmission. I would suggest against diassembling the starter. One of the must do is a bench test of the assembled starter. You can see the mounting ears of the starter and access is from the firewall side.

Yes, starter motor and solenoid. If the problem is with the solenoid contacts, I would not touch the motor.. But that is just me.

Are you still working on this?
I hate to contradict BillyPowe as he claims to have actually done it, but I personally do not believe the solenoid can be serviced without removing the entire starter assembly from the engine/transmission. If you read his words CAREFULLY....there's some room for doubt. In addition, even if the plunger can be swapped, wear or damage to the lever that actually engages/retracts the gear isn't going to get fixed in this manner, or the gear replaced, etc.
As for removing the entire starter:

Where in Arizona are you. I'm in Sun City (Phoenix).

supra yours is just "stuck" pull it out
the original parts lasted 11 years, so I went back with original. that was 2010, and it is now 2017 and we are still driving the LS.
my nephew, who done mine, is a Lexus mechanic, has NEVER replaced a complete Lexus starter, on a side job.
but maybe a SC is different?? do you know Wade??
also here is a current photo of my 209k LS

Thank you very much for your post and photos. As to being stuck, I am pulling as hard as I can and it will not come out... it moves about 1/4 inch but no more. Forgive the likely stupidity of this question, but is it okay for me to pry it out with a screwdriver? I am afraid of damaging something.
Thanks again.
Thanks again.

this is very interesting. I have bad contacts in my starter and have been looking at whether I could just disassemble it in the car or to remove it and put a new starter in, then rebuild the old one for a spare. I think do to the mileage on the old one, and the PITA they are to change in the 400's I will put a new one in and keep the old one for a spare. This a good alternative though!

just looking at the photos.... there is nothing there.
BUT I REMEMBER: Just open up the access panel on the bottom of the tranny where it meets the engine and stick a large allen tool in one of the flywheel holes and slowly turn the engine to see if it will loosen up ?? just a guess
