1098 crank into 948
Happy new year all.
After much searching I have not been able to find myself an inline 1275 or 1098 motor in australia. I am quite sure that the shipping costs to get one here from the UK shall prove prohibitive. I have however found myself a new old stock 1098 crank that is going for the price of one used transverse 1098 crank ( fair trade I'dd say).
So, can I fit a 1098 crank to a 948 block? I have not yet seen it and can not yet verify if it has the 1.75 or 2inch mains.
Is the center main bearing going to be narrower on the 1098 ( i understand you can narrow the block here)?
As the 998 trasverse crank (same stroke as the 948) can be swapped with its 1098 counterpart, am I right in thinking I should not have difficulties with deck height if I use 1098 rods and pistons?
How am I going to go in the cluth/gearbox department with a 948 box? 1098 box will not be avialable.
Has anyone fitted 998/1098 pistons to a 948 block recently (or similar overbores)? I know vizard says its possible but the walls of most blocks have become thinner since then.
I would really appreciate anybodys thought or experiences on the matter.
Thanks

I've seen vizard fettle the blocks to clear long stroke cranks in big bore motors. I might have a look anyway, for the price of the cheap crank I don't mind a bit of grinding and machining.brixtonmorris wrote:you cant.if i remember correctly
i think the throw is to large .
it wont rotate
Ianselva,
the metro pistons were they 60+ on the 948 or 60+ on the metro? Are metro pistons like a 998 piston (we dont have metros in australia)? Did you have any trouble going through bore walls into water jackets?
Thanks alot for the feedback, I guess i'm just going to have to try to fit the parts up to find out.

It is a crank, but I'm not sure exactly what it is. It is printed on a box and comes complete with bearings so the part number might be for the whole kit?
The most popular heads ( in australia) for the 1098 are the 12g295 and the 12g202. i believe the sequence 12g is related to all heads. I'm hoppnig that 88G relates to all cranks, though I suspect it may relate to crank and bearing kits. I also understand that the part number is one less than the number on the part. Something to do with drawing numbers and the like.
Thanks all the same.

yes and no - Sometimes the number on the part is the casting number, and the part number relates to whatever it got machined into (ie one casting could be used to make parts to a number of different drawings)the part number is one less than the number on the part. Something to do with drawing numbers and the like.

1098 Crank into 948
Hello from Adelaide, Australia. I can't be certain on your crank swap, but I can advise you on your other question, overboring 948 block. I have just fitted 0.040"+ 998 pistons on a rebuild of my 948 block. No problems with this overbore in my case.
QUESTION:
Can anyone advise which engine backplate I need to use to fit a ribbed 1098 gearbox to my 948 block. I have the thicker 1098 back plate and I also have the pressed metal backplate from the 948 engine. Can anyone help?? the plates are interchangable, but one is substantially thicker than the other......
regards, Peter
