BJ40 Starter problems (1 Viewer)

[lostmarbles]

Hi Albert

I just searched my EPC using my BJ40 VIN details and it shows the same "bolt" in place of my "cut-out/shut-off switch". Yet my cruiser is definitely "standard" for this part of the world in having that cut-out switch.

I think this shows yet again that the EPC is not "gospel". (The EPC is correct for your vehicle but not mine.)

But I seem to remember you don't have any EDIC (electric diesel injection control) either - And the cut-out switch is there on my vehicle to work with my EDIC. So I guess this tells us there were "with EDIC" and "without EDIC" versions of the BJ40 produced by Toyota in 1979. And in this respect - our engines are different. (I have seen quite a few references to "without EDIC versions" before but have never seen one "in the flesh".)

And it looks like the same wiring loom may have been used for "with EDIC" and "without EDIC" versions which would explain the disused connectors/wires on "without EDIC" versions. (In different threads we established that the same loom is used for 12V and 24V versions so this is not really surprising I guess.)

My oil cooler:


On the subject of engine reconditioning, I think most people would advise using only a shop that has a proven record in reconditioning diesel engines (and preferably Toyota diesels too). They need to be able to strip, clean and reassemble while replacing or reconditioning anything that isn't "within-spec". These days, there are very few "mechanics" that have the necessary skills for engine reconditioning because machining, engine tolerances, etc are no longer part of a mechanics "normal work" or "normal training".

But budget contraints can force one into trying "short-cuts".

I think the absence of feedback on your engine-repair strategy is because people recognise the difficulty you're in and the risks you face.

cheers
Tom

My saga

Thank Tom. I realize that the experts on the site like you cringe when reading some of my recent posts. The nature of the problem is sort of in that red flag zone. A total re-build is the right thing to do not knowing the condition of the engine and other problems I may face if I only make partial repairs for now. From reading the other posts, people with similar situations seemed to have more time with their vehicles, had heard them run well before and could identify strange sounds or different from the norm, type sounds. I don't have the history and unfortunately do not have room in my garage to tear the engine apart myself. Even though I would need a lot of help along the way, that is what I would love to do.

I am in the process of adding things up and the mechanic is making a parts list. In the mean time, I'm trying to keep informed and reading all I can on mudd so that I can make better decisions. Ultimately, to do things the way I like and without having a machine shop friend, things will be very expensive and may be cost prohibitive.

Connecting rods

Guys why do rebuild kits not include connecting rods? Is it common practice to have them machined if they are out of round? How many times can a conrod be machined? Is it likely that in my situation my con rods would not be re-useable?

I had a few other questions related to buying a complete rebuild kit:
Is there a way to measure/confirm outside diameter of a cylinder liner without dismantling the engine? Can this be done from the bottom end?
Can I visually check if the thrust washers are separate from the main bearings without dismantling the engine?
Can I check if I have a 3 or 5 cam bearing without dismantling the engine?

Oh - One more thing. If that relay on your firewall is indeed your "starter relay" then it is an aftermarket one I think. Here is a photo of my starter relay on my 1979 BJ40 where it sits in the passenger footwell area behind that big plastic rectangular air duct (by the way - mine's a RH drive vehicle):

I suspect, from the thickness of the wiring on your firewall-mounted one, that it is more likely to be an aftermarket relay for something else - like the glow plugs perhaps.

very nice pics, I just recently acquire a bj40 1978, I'm from Costa Rica, I'm trying to rebuild the wiring. I bought a wiring very old i would love more pictures from yours if is possible. Thanks in advance. I haven't found the correct wiring diagram, both i found wiring looks very different from the paper.
