[drew-turbo]

Will fit fine. Pin diametre is the same. Just the rod appearence varis a little...

cheers pal thats spot on

Have in mind when mixing parts that cylinder and piston require a specific clearence the same with the pin and piston . Thats why piston is marked with 1,2,3 and other diameters like pin,bearings have their own marking and specs.

to answer the question simply, yes the glanza pistons are essentially the same as the gt onesas the engines blocks are exactly the same.

gudgeon pin sizes are the same on all of the factory toyota pistons.
as said above when changing pistons you need to get the one to suit your bore clearances.
glanza pistons are mainly the mark 3 versions.

Mark 1 --- 73.89~73.90mm
Mark 2 --- 73.90~73.91mm
Mark 3 --- 73.91~73.92mm


some of the glanza conrods are slightly smaller (skinny) than the earlier model ones as also previously mentioned.

so what vesion are GT's usually, or does it vary between 1-2?

mine was mark 2 but better check the piston top between valve pockets.

theres a no 2 and an arrow pointing to eng front i think is that it?
How do you remove the gudgeon pin from the piston?

 

[billybob]

you will have to get it pressed off lad in a machine shop ,aswell when done chek the piston for warped a bit as pressure apply wrong when taking off piston has to be done right

kk i read it on a thread uve gt 2 heat up the piston nt the pin and either bash or press it out, how wud you get it back in just press it bk in with no heat?

[keya]

na im gud thanks m8, need it runnin 4 friday n i allready gt the bits to sort it

 

[Jaf_ep91]

ok

ok mate sorry i cant be of help.

 

[billybob]

the rod has to be heated up lad then push the pin in

 

[keya]

thought this much cheers 4 the help m8. u can all have some reps

removing the gudgeon pin is not something you should be attempting yourself. it should only be done by an experienced machine shop or engine reconditioners. i have done numerous myself doing quite a lot of engine work in my job, but have seen it go wrong very easily. they are in there very tight. by overheating the piston it will warp and become useless. there is an art to doing it correctly.

the number on the crown (top) of your piston is what mark piston you have. in your case its a 2. the arrow points to the front of the engine as you suspected.
hope this helps

if you are building the engine yourself make sure the ring gaps in the bores are within the correct tolerances. especially on the one with the broken piston. obviously other things also need to checked as well.
