Which starter for a 1HZ/H55 setup (1 Viewer)

[davegonz]

I have two starters that my buddy gave me and don't know which one to use. They look like they're mirror images of each other.

I like how much bigger these gear reduction starters are compared to one off of a 2F. These things are massive!

Is there a denso or toyota part number on them?

I have one off my 1hz waiting for a rebuild, can take pics tomorrow for you.

Thanks .

This is the only part number I can find.

The early (90 -96) 1HZ, uses a 28100-17040.

That part number looks to be from a 24v.

The other starter has no part number.

Some photos of my spare starter.

Thanks for the pics!

Since it appears the clocking is correct on the starter you have, one option is to get a 12V forklift starter, 28100-54090, and swap the nose pieces. When I bought the engine from Georg, he gave me the rebuilt forklift starter, and I did the swap. Easy job.

Here's a dumb question, but is there a way to test the starter on the bench and determine whether it is a 12V or 24V? As I mentioned before, both spun up when I applied 12V.

Both starters will operate on either voltage. The 24V model should run approximately half speed on 12V with no load. By putting 24V on a 12V starter, it will try to run a twice normal speed. In other words, the speed of a DC motor is related to the voltage applied. However, to develop the proper torque, a starter needs to be operated at rated voltage, or it will overheat. I'd believe the part number, which indicates it's a 24V model.

That's what I was thinking but was hoping otherwise.

28100-17020, this number is also for a 24v. And its off a 90-92 1PZ 1HZ 1HD T

This a 12v number 28100-17060, but I bet there are more
