Question No Manual for 323 BJ Astina with FP engine

Hi Everyone,

I have a major problem. I have a Mazda 323 Astina BJ Series with a 1.8ltr FP engine. I am basically rebuilding it with a completely reconditioned head, new bearings, rings, etc...

Mazda Australia has basically wiped their hands of me saying that they do not have any details on the information I require.

This information I require is:
  • Torque Settings on the Conrod Bolts
  • Torque Settings on the Crankshaft Cap Bolts
And whether they are torque to yield bolts and if so, where do I get a set of replacement bolts.

It seems to me that the 323 manual does not have this engine (i.e. FP), but the 626 does, and I believe they are the same, however, I m not 100% certain.

Could someone help me with:
a) the settings and if they are torque to yield
b) a copy of the manual that backs this up

Thanks in advance.

Regards,
Andrew

If I have time at work tomorrow, I will blow the dust off our old paper workshop manuals and see If I can find a 323 manual with the 1.8.

Also can you give me the year & chassis number?

Hi Grim Reaper,

Really appreciate it. Seems like the FP engine was not in the 323 BJ Manual, however could be in the 626 manual for the same year. I downloaded manuals from all over the place, no luck.

But as to the style, BJ 2000 was per below image: (NB: Not our car, but you get the gist).

VIN: JM0BJ10P100124404 10/00

Thanks,
Andrew.

Ive looked in both BJ 323 & GF 626 manuals and they only cover cylinder head gasket replacement, nothing about the bittom end.

I will try Mazda Technical assist and see if anyone can help.

Update, had a look in the GE Mazda 626 book ( 1991 -1996) with the FP & FS engine, not sure its the same as your BJ.


However,

Connecting rod bolts, 47.7mm - 47.3mn spec. Max 48.0mm

Main bearing cap nolrs, 67.7mm - 68.3mm spec . Max 69mm

Hi Grim_Reaper,

I really appreciate this.

It is what I have been looking for. The BJ is an FP engine, although not the correct years, mine is 2000, I would imagine that the values here should be correct. What does your experience say in this case?

If the bolt lengths etc are the same they would be the same specs?

I will check the bolt lengths. And unfortunately, it looks like it is coming back with details I hoped were different.

I do not have the experience here, and need some guidance/help from the more experienced.

These are + 90, so from my understanding are "Torque to yield" bolts. Again, from my understanding this means that they should be replaced, however, the manual there says "replace as required".

What does this mean in this context?
Do they need to be replaced?

And if new bolts are required, where can I get replacements?

Regards,
Andrew.

I have very limited experience with rebuilding engines.

Yes these bolts are torque to yield, hence the length specs, yes they can be reused, as long as they are within spec. Some manufactures will say replace regardless, Mazda believes there is a stretch limit than can be accommodated before the bolts reach their stress limit.

Grim_reaper, thanks very much for your help so far. I really appreciate it.

All bolts were within spec. At the top end, but within defined range. None anywhere near max. So all good. Thanks.

I have another question if you would be so kind.

It looks like there is a requirement for an o-ring between the sump base and the block. So I explain this well, there is in the setup the Block, sump base and then oil pan. Between the sump base and the block is the following:


Reference is bottom middle, sump base is the section above that is where the oil pickup attaches.


I have a number of o-rings in the kit, and one seems to fit, however there are no rub marks on the sump base suggesting that there was not one here. In addition, the diagram for the assembly does not suggest one. It just looks odd.

Thoughts?

Regards,
Andrew.
