starter motor : 28100-17030 or 28100-17050

[Firewout]

hi guys,
during the MOT test this morning, the starter motor thought that it would be the right moment to start smoking and spinning.
I had to disconnect the 2 batteries and the MOT guys pushed it outside the garage.
looking for a new starter motor now and saw 2 part numbers for the HDFT engine.

in my epc, the 17030 is listed but I wonder what the difference is between the 2.

starter contacts have replaced last year btw.

Hi Firewout always the way when least expecting.
There are few on ebay that might be of help like this one below. Difference prices but worth a look.

All the best

Beware. One has 5 teeth, the other 6. You need to find out which one you have.

You may not need to replace it. You say the starter contacts were replaced, could it be the back plate screws have come loose on the solenoid? I had this where the plate fell off and the plunger moved against the contacts and it set light to my starter so HAD to be replaced.
Also, did you replace with the extended contacts?
Lastly give Robson and Francis a call for replacement motor or parts. You will need to check the amount of teeth on the pinion.

 

[Firewout]

12 teeth
extended contacts
back plate screws ok
my best guess : contact ring shifted and shorted the 12 volt coming from start relay.

In that case there are either 5 or 6 teeth on the 1HD-T whereas you were talking about the 1HD-FT. My bad.

€125 delivered sounds far too cheap to me. Hope it’s worth the money.

we'll see. If it isn't, I'll surely let you guys know.

I think we had this come up last year? There are 12 teeth on the 24v starter on the 1 HDT, and HD-FT, there is a 12 volt 12 teeth version 2.5kw. On the 100 (HD-FT) , they are 12 volt (3kw) and have 11 teeth.

11 teeth 12 volt 3kw

12 teeth 24v 4.5kw

Side by side pic.

Maybe I was just 6 teeth out!
I knew there was 1 tooth difference. Mine has 12 in that case though i accidentally fitted an 11 tooth one and it worked for about 6 years until it stripped the teeth. But replaced the pinion with the 12 tooth one and all is good now. Mine was a 24Volt on a 12 valve 1HD-T

I think I’d be going back to the plunger supplier (presumably you replaced the plunger when you replaced the contacts) and having some words with them. Something clearly isn’t right in there for that to happen under normal conditions. Could it be the spring got displaced?

 

[Firewout]

presumably you replaced the plunger when you replaced the contacts

erm no....

 

[StarCruiser]

erm no....

Ok, so original plunger. Was that a Denso starter or an aftermarket?

I’m just trying to work out how this happened in a normal condition so if need be it could perhaps be prevented.

 

[Firewout]

Denso

this is how it looked before I put the new contacts in :

this is how it looks now :
it smoked a lot and the motor was spinning freely without the contact being on. The plunger was stuck with the contacts closed.

 

[Dave2000]

Plunger and contacts are traditionally replaced as a set.

Already a known issue on the 80's replacing just one half exacerbated the problem, I did not know you could purchase them separately?

TBH I thought Toyota sold a kit, this had the plunger, spring, a pair of contacts, and the necessary insulators and nuts?
