1HD-T 24v to 12v Starter Conversion Question (1 Viewer)

[CaptBeardilocks]

Hey all,

I'm swapping the 1HD-T from my parts rig into my FZJ80. I plan on deleting the 24v starter system as part of the move. I was wondering what folks on here were using for a 12v starter? The top options seem to be the factory starter (28100-17010) for ~$600 and a Denki for around ~$125. (Partsouq prices).

I usually go Toyota only but DAMN. I imagine if I dig hard enough I might find a Bosch option or something else. I was just wondering what the other converts were using and how they held up over time.

Cheers.

Hey Captain,

I bought brand new the Factory Toyota 12V starter for a US spec 2LTE available here stateside. I’m not sure if it is still available and I can’t recall the part number (maybe it’s the one you listed?) but it works and works well.

You can swap the 1HZ 12V Starter. Cruiser Brothers in Stockton have them.

 

[CaptBeardilocks]

Looks like the same deal for the 2LTE starter: Toyota for ~$500 and Denki for around ~$100.

Cruiser Brothers lists the same Toyota Part number but sell Terrain Tamer. Not sure if TT make those in house or is using another manufacturer...

 

[Dilspec]

TT has a good reputation, I wouldn't hesitate to use their products and I do. At the end of the day it's your choice, we just equipped you with some options.

 

[CaptBeardilocks]

I’m about to order a clutch kit from them so I may throw the starter in too. Hate paying ~$450 for a starter but it’s still almost half the price of the 24v. Lol.

 

[CaptBeardilocks]

Or you can get an 80 series 12V starter and change the electrical connection at the harness side.

And you are done.

80 series FZJ 12v or HDJ 80 series 12v?

Should already be a 12v Alternator on the 1HDT correct? Just need to change out the starter & wiring. Or I missed something major in may research which is COMPLETELY plausible. lol.

s***. My bad. I haven’t had my Sanka yet. I thought we were talking alternators.

Disregard my posts.

Alternator is 12V. Starting circuit is 24V and that’s it. Entire truck is 12V aside from starting.

If it's the same as a 1HZ, a Cummins starter motor will work:

Last summer dad picked up this relatively rust free cruiser off of craigslist with no title and no drivetrain. After some paper work and a few months of waiting, he received the bonded title. With the title in hand, we started the parts buying spree by sourcing a 1HZ and H55 from @joekatana...

I stock the factory 1HZ/1HDT Toyota 12v starter with pig tail $400

Thanks for all the leads on starters. Plenty of choices at least.

Does anyone know if the starter relay (28300-17020, located inside the left fender) is part of the 24v starter system or if it is still needed on a 12v conversion?

The relay from the 24v system will work if that’s what you’re asking.

 

[CaptBeardilocks]

I was curious if it was still needed after a 12v swap. ie: if it was one of the parts that are removed from the equation when moving away from 24v.

Your answer would imply that it is still needed after the conversion to 12v.

Is it a part that fails fairly commonly? Good idea to replace as long as it's out? Or fairly bulletproof?

 

[mudandrock]

You should use the relay. It will start without it, but will eventually damage the internals of the starter over time.

If you can't find a closer option, I have some remanufactured Denso 1HZ starters. $175USD in box or $150USD no box shipped to your location.

Do you still have any of these, Brau? Thanks, Pete
