3T Versus 3T GTE conrods

[CHB]

how to get these rods onto the crank?? it looks like it is in one piece

[3sgte]

Could you please post a pic with the big end cap off?

Seems that the socks came off while you were waiting...

[setsuna]

its extremely well mated pair of surfaces, if you look closely, you can just see a hairline join..



and with the endcap partially off. you can see a centering dowel type thingy where the bolt goes through into the rod side..



and it all the way off!

They do look like a VERY nice set of rods.

I was wondering where the join was myself. Very well matted.

Guys,
I just got some eagle rods and notice that they don't have an oil gallery for the pin? I see a small hole at the top of the rod, I assume this will get enough lubrication?

Based on this I'm also guessing that I can use either 2T or 3T G rod bearings as no oil hole is needed?

Cheers,
Simon

Yes, the little end needs only a very small amount of lubrication. It will get oil that drips off the under side of the piston crown.

I think that the oil squirter hole should be drilled into the rod. This is there to squirt oil on the load side of the bore.

Jase,
OK, a couple of dumb questions-

Which is the correct side and location for the hole? I assume only a small hole is needed, eg 1mm?
Also what happens if I don't drill the hole and if I do won't it weaken the rod?

Finally does the stock rod have this squirter hole?

on the right side (from the driver's seat)

Also what happens if I don't drill the hole and if I do won't it weaken the rod?

I don't have the definitive answer to the first part of this question: I suspect that there will be enough oil flying around to offer sufficient lubrication to that area, but the factory did it for a reason, so maybe longevity will suffer. As for the rod being weakened; no. rods generally don't break in that area, they break further up the beam.

Finally does the stock rod have this squirter hole?

Yes it does.

Thanx Jase, a great help as usual.

So my best bet would be to drill a hole in the same spot and size as the stock rods?

Anyone got a pic of the hole in the stock rod? I'm a slow worker and am just gathering bits for a rebuild ATM

Get you hands on a second hand bearing (the 3T bearings have the hole in a different spot to the 3T GTE bearings), and use that as your guide. The hole will only need to be 1.2 to 1.5mm maximum with a chamfer to lead into the hole.

4340 is tough material. I suggest the use of a cobalt drill, low speeds (relative to diameter - in this case 1200rpm is still slow for the drill), make sure that the drill hole is started with a centre drill and use Rocol RTD cutting compound.

OK thanks. Can I still buy aftermarket bearings specifically for the 3T GTE from someone like S Wilkins? Or is Toyota the only option for the right bearings?

[sillycar chick]

SW has them listed on their site... maybe give them a call and ask them about it?
(Im keen to know as I will be going down the same road as you when I get some time and money to play with my 3tgte )

[YelloRolla]

They're available from other bearing manufacturers. I know that NDC do them, I will see if I can find the part number.

Simon,

If your drilling the holes anyway then you can just drill them for the 2T bearings

Rod,
I know the location of the 2T holes are different, but is the bearing width etc the same as the 3T GTE bearings?

I know its not required, but I think I'll track down the 3T GTE bearings as everything else in the engine will be top quality....
I'll call Toyota and get a price for them..

Cheers,
Simon
