IS300 and GS300 Xenon bulbs the same?

Checking on http://japan-parts.eu/, part numbers are as follows:

JCE10 IS300 – BULB, DISCHARGE HEADLAMP 90981-20007

JZS160 GS300 – BULB, DISCHARGE HEADLAMP 90981-20001

Visually they look identical.

Narva catalogue lists Narva 49301 is listed as fitting both applications.

http://xenonlight.com.ua/ lists a Philips D4R 42406 XenEco as fitting both applications.

Cressida Lower Control Arm Polyurethane Bushes – Same as IS300?

Regarding front lower control arm inner bushes, this site has the part listed as fitting both MX83 Cressida and JCE10 IS300:

http://superpro.suspension.parts/spf3039k

As the superpro catalogue doesn’t list a MX83 lower control arm inner bush, it would be nice to confirm that it fits. Here’s the superpro info page for that part:

Superpro SPF3039K page

Note it doesn’t list MX83 on the application list.

Having both XE10 bushes and MX83 arms, I can confirm this WILL NOT fit. Measurements are taken off a new set of XE10 TRD bushes, and a set of used oem MX83 lower arms. Note the superpro part doesn’t include an outer shell, so measurements are taken on the inside of the existing shell.

XE10 on the left, Cressida on the right:

Lexus IS200 starter motor brush repair

This procedure is relevant to other Toyota planetary gear starters.

The exact factory procedure is under Starter Components in the TSRM

Symptoms of the problem:

  • No tick, tack from the starter solenoid when turning the key.
  • Tapping the starter with a stick while turning the key agitates the starter enough to start.

The starter solenoid has 1 power and 2 grounds: one ground to the body of the starter, and one ground through the starter motor. Both grounds need to be connected for the electromagnetic solenoid to pull in.

The problem is not with the solenoid itself, but with the grounding through the starter. This can be verified by:

  • Disconnecting the high current input to the solenoid input post
  • Disconnecting the link between the solenoid output post and the starter motor
  • Connecting ground to the solenoid output post
  • Connecting ground to the starter assembly body

Then power the solenoid signal +12v, it should pull in reliably every time.

Tapping the starter with a stick agitates the motor brushes to make better contact on the commutator, making a better ground through the motor. Based on these symptoms the brushes or commutator in the starter motor are worn out.

Pull the starter and dissassemble:

Usually we start by taking the other end off, but here we can see the brushes are 100% finished. 2 barely protrude from the brush holders. Where did they go? That pile of graphite tells the story.

The commutator is scored and filled with worn graphite. I wasn’t sure if this would be reusable.

Cleaned off and sanded it down

The minimum service specification is 27.0mm. This one is OK to be reused.

Here’s the brush holder end. The brush holder assembly is replaceable and can be ordered from Toyota. This is for a 1999 IS200 with a 0.8kw starter. If yours is different check the catalogue

  • 1x 28140-70020 HOLDER ASSY, STARTER BRUSH
  • 2x 28142-70020 STARTER KIT (these are the negative brushes)

The brush holder assembly contains the positive brushes. The negative brushes are separate and have to be crimped on to posts on the field body. Details of this whole job are in the service manual.
