what 2B engine do I have?

[Folkert]

hi dieselers,

I have a march/april 1981 BJ44V with the stock 2B engine in it, doing a resto and stumbled upon the engine valve cover decals for the 2B engine @ cruiserparts.net

I found out that they offer 2 versions: there is a orange version and a green version, they are the same except for the timing info.

what version do I need? how can I find out?


see links for the pics @ cruiserparts.net:

green 2B decal
2B Valve Clearance Sticker Green [11293-57030-G] - $12.99 : CruiserParts.net, Toyota Landcruiser Parts

orange 2B decal
2B Valve Clearance Sticker Orange [11293-57030-O] - $12.99 : CruiserParts.net, Toyota Landcruiser Parts

one has the same info as the B engine, the other as the 3B engine...
since mine is pretty close to the 3B introduction date, I guess I need the one with the same timing settings as the 3B?

hope someones here knows...

Wow, thats an odd one. Same part number for both stickers too, bizarre.

Anyway... since the EPC carries the same p/n for the sticker on all 2Bs, the only clue we have is that overall BJ44 production was split into 08/1980 - 09/1981 and 10/1981 - 09/1982 variants.

Funny thing is that the EPC lists the cover sub ass'y (which includes the sticker) with a note that says the one-and-only p/n is valid up till 08/1984. But there is zero mention in the EPC of a 2B used on any Toyota vehicle (I checked things like Coaster busses, etc) after 1982. Soooooo... I dunno; stumped.

the first coaster also had the 2 b engine, and i have a toyota service manual for the B and 2B engines dated 1977, so i assume the "older" timing settings are for the 2B used in the coasters and maybe early Bj44/41, then they used the new timing like they also use on the 3B engine? question is when did they change?
how can i check what timing is correct on my vehicle?

 

[amaurer]

2B FSM, maybe?

 

[Folkert]

fsm? factory shop manual?

2B FSM, maybe?

 

[amaurer]

Yeah.

I'm not sure if one exists for the 2B - I'm not sure they'd make a translated copy for a JDM engine. But who knows, maybe it does?

 

[Folkert]

hmm, don't think so too..

The FSM I have is in English, but that one is for a 2B Coaster engine (manual is printed in 1977), so it probably doesn't cover the later 2B (1981) engines. Not sure about the differences though.

found this manual as free PDF download here:

According to my FSM for the B, 2B, 3B dated Aug. 1980 it is 14 degrees BTDC. No mention of 10 degrees in this manual.

hi daryl, thanks for the very usefull info,
in my FSM of 1977 it says 10 degrees BTDC for a 2B.. so that must indicate the change of timing setting to 14 degrees BTDC was before august 1980 or at least from aug 1980 on...

I also have the 1977 b, 2b manual. I must look and see if that is for the dyna. Is the dyne a BU code?

Cheers,

[Folkert]

no its the coaster that already had a 2B engine at that time..
the dyna had a B and 3B engine, but never a 2B.

In my opinion, the sticker difference could be dependant on

• date of production, or
• vehicle model

I've been searching but I can't find any reliable information either way.

I see that there were block changes for the 2B engine (as used in the BJ41 and/or BJ44 model cruisers) which could support the "date of production" idea. (Aug 80 to Jan 82 was 11401-59095. Then 59135 till Sept 82. Then 59215 till Oct 82.)

But then again, perhaps all the Coaster 2B engines got the 14 degree stickers and all the Cruiser 2B engines got the 10 degree stickers? (Are the valve clearances different too?)

I think the best way of finding out is simply to PM owners of unmolested BJ41 and BJ44 models and get them to post images of their valve cover stickers.

Here's mine for a 1979 B engine:

Here is where the change over is important. Your rad hose is on the right side of the vehicle and therefore have all of the B series glow and relay parts for the engine. This includes bus bar, injection parts, and a different head from the 8/80 spec'ed (but as we are discussing in another thread, not well adhered to) parts.

I would guess the 2B decal that match the B series clearances is what you need.If you had the engine like mine with all of the 3B series stuff, you would use the 3b clearance info... because the head is essentially a 3b head on mine and a B head on yours... Look at the EPC and they will show you the differences if you look at the adjoining pages... Use my vin BJ44-002769 as it will show both options...

Let me know if this helps at all and I will do some more research on this end.

[Folkert]

either way, i ordered both decals...
time will tell which one is right
breck, do you still have the decal on the cover?

 

[BreckenridgeCruiser]

I don't have a decal any more... I should be interested in buying whichever you don't use as I am pretty sure we have the opposite 2Bs .

sorry tom,
completely forgot to thank you for the info and good thoughts,
will indeed ask around what other 2b owners have on their cover.

I had trouble downloading those images before but they worked OK today:

....

Looks like the clearances are the same but it is just the injection timing that is different Craig

However I search, I just see one sticker part number for all the cruiser 2B engines. And it sure seems odd to me that Toyota would apply exactly the same part number to two very different stickers!

Yes. I still see this as the best option for finding out the truth.

Interestingly ToyoDIY lists just the part number and price for the sticker without giving an orange/green option. (I was wondering if these Cruiserparts stickers were reproductions ... but their images certainly imply "genuine Toyota".)

Edit: We've since discovered they sell both "genuine Toyota" and "reproductions" (with the reproductions aimed at being perfect reproductions of originals."

 

[BreckenridgeCruiser]

AFAIK, the difference in the pre and post 8/80 2Bs are the head... Maybe they adjusted the timing based on the difference? When I said clearances, I really was supposed to be saying timing... whoops! Good catch Marbles.

Your b series has a 10 timing set so I wonder what the spec is for a 3b?

 

[Folkert]

dont think they are repro's, also says on the site they are genuine toyota, while some decals say " other manufacturer"
dont think its that interesting as well for them to reproduce, i mean how many 2b owners are there...

just my thoughts...

 

[Folkert]

IIRC the decal of the 3B said 14 BTDC

but when i look at the other decals on the cruisercorps.net site they also have 2 different B engine versions, also with 10 and 14 btdc... a black and a blue one

how confusing, this completely ruins the idea that newer engines had 14 and older 10 btdc.... or...
