Yamaha 14B engines (1 Viewer)

[roscoFJ73]

I haven't heard of these before. It came through on my FB page. Yamamha Marine could be an emergency parts supplier or engine swap option for B engine owners.
Marinised Toyota 14B sold by Yamaha. EDIT. It is actually a 14 BT in case you hadnt worked it out for yourself.

I've got an FSM for it, but being marinised there are a few differences. I did manage to work things out between the factory Toyota 14B manual and the Yamaha ME372 sti manual (that's the engine name).

Good video with sound of a ME372 blasting along

Yeah, I found that video a while back on a Brazilian 4x4 forum. The 14B (non factory turbo) came out with the Banderainte in Brazil, so they have a bit of knowhow on the non turbo version.

I had a look at this a while ago, while the block is 14bt, it looks to have a different head than the heads used in trucks. It looked to have glow plugs which I have not seen in the 13bt's.

It wouldnt surprise me, the 4B has glow plugs


And there is also the ME420STI which appears to be a 1HD T or later

Would love to know how many RPM that is. Sounds like it's howling.

 

[roscoFJ73]

I would say about 1500 at the low rpm and 2500 on the high end.

Where can you see glow plugs? Looks like the same as my 14BT head/injectors:

i wonder why they didnt choose the 15b as a base engine

Have a closer look at the other pic.
There's a flat buss bar running beside the fuel return line that is connecting them. Beside each injector you can just see the top of a plastic screw cap that is used on glow plugs

 

[crave reFleXion]

Gotcha. That's interesting... I wouldn't think it would be necessary on a direct injection engine, but there you go.

I wonder if that is the same engine as the yanmar 6lp, I didn't even realize that Yamaha was making the diesel Toyota engines

Yanmar 6lp

So I have this in the shop that I can pick up for very short money, I rebuild these things for a living so labor is good, I know parts can be expensive but we get discounts so not to bad. I have looked to see if anyone has done this but a quick search did not find me much so does anyone have...

There are references for glow plugs for 15B as well as Daihatsu 14B

I would say it is the same engine. Yamaha would be buying the engines from Toyota and marinising them most likely.

The block is actually listed as a daihatsu 14B in the FSM, so that's probably why.

 

[roscoFJ73]

Which block, which FSM? There must be a good reason why they used the glow plugs as the glowscreen would most likely be cheaper.
With glow plugs you still have 3 plugs when one dies but once a glow screen gives up the ghost you have nothing to warm the engine on a cold start.
Most of the references were for 24v engines.

Just saw this today, I think some of you might appreciate it

Lotsa fun but what a waste of a good engine.

It's not a waste if that's your hobby and what you enjoy doing on the weekends. The same guy could say the same thing about people going boating on weekends. Not everyone wants the same toys, I just like seeing engines in any vehicle.
