18RG early model conrod

as in title I am after one early model 18RG con rod.
Part number must be 12GU or 12GM.
I realise this is unlikely, but what the hell, I want one.
If you've got a whole set, I may still be interested but I only need one.
Cheers

What happened to the ones i sold you? I still have those other 3. I'll check to see if they have those numbers on them.

Thanks Michael,
I don't think the rods had been balanced.  When I got home I weighed them and they weren't all the same (3 x 62AU, 1 x 62AM)
I may mix and match them with some others I have to try to get a full set of similar weights, then get them linished and balanced.
I weighed all the rods I have, and the 12GU and 12GM ones are obviosly different from the later models. They appear to be of slightly different colour and the materials are much heavier. The 12GU and 12GM rods were within a gram of each other.
The 61AU and 61AM rods are different weights to each other.
The 62AU and 62AM rods are different weights to each other.
Anyone got any spare rods?
Are the rods you still have the ones I saw from the 18RGEU motor Michael, or are they other ones?

Other ones. 3 with squares on them. Sold one to some guy in Qld through here not long ago.
I've been told that the conrods them selves don't get balanced, it's the crank that gets balanced. Since you have the balanced crank, all should be fine.
But if you need some more conrods, let me know.

What are the number cast into those rods Michael, I may be interested depending on what they are.
A propper balance job will do the rods & pistons (big and small end), crank, harmonic balancer and flywheel.
I have seen 18RG rods that have been balanced so it does got done.
I just hope that that crank was balanced separately to the rods, otherwise it won't be too much good to me unless I use those rods I got from you.

In MY opinion
im sure your on the right track... crank is balanced, rods are weighed sepperatly to within tolerances ie 1grams or less of eack other then put on the crank.
There is no way that im aware of that enables you to balance it all together??
Ps
Thanks for the help the other day  it was the Air Valve, and the brake booster barb, however the order of the sensors on the thermostat will be hit and miss

Thanks for that phill. It is always good to have someone to confirm your thoughts.
I'm glad that the EFI stuff is getting sorted out. As for the thermostat sensors I don't think the order of the green and brown sensors is that critical.
It would be good to have a look at how they should be though.
I reckon a toyota parts dealer should have that information on microfish (sp?). They should at least have it for an analogue 22RE.

I have a single conrod, part number is 61CM, I can weigh it if you would like.
As for the balancing, I recently discussed the full procedure with a friend of mine who is an engine machinist. His description was that each item is weighed separately, and brought to within 1 gram of each other (con rod, piston, gudgeon pin, conrod-endcap) and then the total weight of each set is passed on to the machine shop, who will match the balancing of the crank to the weight of each piston/rod set. dont forget to used the weight of the circlips in the gudgeon pin balancing, the weight of the rod bolts with the rod itself, the weight of the nuts with the rod endcap and the weight of the rings with the pistons. You should discuss with your crank machinist as to whether or not the weight of the bearings should be included. also one complete piston/rod set with rings should be supplied to the machinist so that their balancing calculations can be based on their weight analysis of the set. Harmonic balancer and flywheel are balanced separately.
Hope this helps to make sense of this all. If you are interested in the rod I have (doubt if you will be) then email me at O_man_ra23@yahoo.com.au
Cheers, Owen

Thanks for the info.
That is pretty much what I had been told and what I fugured.
I'll contact you about the con rod, I just have to check the part numbers that I already have to see if it will complete a set.

I am intersted in the rod.
Does it have a little square cast into it just up the shaft from the Toyota symbol on the front of the rod?
Are you able to get me some photos if certain parts of it?
I'd like the following photos.
-Front on photo of the small end casting
-Front photo of the big end where the cap meets the rod (thrust flange)
-Rear photo of the big end where the cap meets the rod (thrust flange).
And yes, I'd love to know what weight it is.
How much do you want for it?
Thanks Owen
