I see quite a few new engine parts available for 3B engines but seldom see any available for my smaller (and less common) B engine. (Looking on places like eBay.)
Yet I know that the following parts are common to both engines:
So if anyone knows of other ENGINE PARTS that are interchangeable between these engines, could they please help me by posting replies here?
PS. I'm trying to update this post (and/or #5 post) as I go (with info I gain from working on this thread)
Edit 12 Sept 08 - Post No.4 in this thread talks about starter motor interchangeability: -

And here's another thread:

So it looks like the B engine in a 1979-onwards BJ40 employs the same 2.5kW gear-reduction starter motor as the 3B in a 1982 BJ42 for instance.
But if your looking for a replacement starter motor for your B or 3B engine, check out this thread first:
https://forum.ih8mud.com/diesel-tech-24-volts-systems/248398-3b-starter-compatibility.html
As you can see from reading it, you may be able to buy a starter that was designed for an entirely different vehicle (and as such, may be cheaper and more readily-available in your country) and then simply swap your old "starter nose" onto it to make it fit your vehicle.
And this thread here talks about replacing a 2B engine with a 3B.
https://forum.ih8mud.com/diesel-tec...swapping-lhd-3b-into-rhd-1981-bj-44-w-2b.html
So it appears that a "latemodel" B or 2B bellhousing bolts straight up to a 3B (as used in a BJ42) with the original B/2B engine mounts able to be re-used on the 3B. (Sounds almost too good to be true!) I guess a feature to look for is that both original and transplant engines have/had "gear-reduction starter motors" - because I have heard of odd-ball early B-engines (with simpler/lower-torque starters) that had significant differences from the 3B (making such transplants very much more difficult.)
Thanks in advance for any help and/or corrections offered.
Note: This all gets a little complicated because two engines can have the same designation (B, 3B or whatever) yet still have differences. For instance I know some 3B engines have rotary injection pumps instead of the more rugged/dependable in-line type. And while a 3B in a BJ42 may use the same glow plugs as my B engine in my BJ40, a 3B in a BJ60 will not. Furthermore, a 24 volt model will CERTAINLY use different glow plugs to a 12 volt model. (Note: Even some 3B-powered BJ42s use different glow plugs. For instance a 1984 12 Volt BJ42 will feature "superglow" and be fitted with 6V plugs.)
Yet I know that the following parts are common to both engines:
- oil filter (Toyota 15600-41010, Ryco Z9, AC PF2, Highway 51016, FRAM PH8A)
- fuel filter (Ryco Z169A, FRAM P4178, etc)
- primer pump (Bosch 2 447 010 033, Bosch 2 447 010 038, Bosch 2 447 222 125, Bosch 2 447 222 126, Denso 09219-50)
- Injection pump diaphragm (Denso 090580-0041) where an "in-line type" injector pump is utilised
- Glow plugs 8.5V (Toyota 19850-68030 or HKT PT104) - provided the engine utilises 12V-battery-power and provided it has a MANUAL glow sytem (without "superglow" feature)
So if anyone knows of other ENGINE PARTS that are interchangeable between these engines, could they please help me by posting replies here?
