Getting the 2t-g head off.

[andurils_sheath]

Hey guys,

need help with my 2t-g. I'm trying to get the head off and i need to take off the cam wheels to get the timing chain off. Im having real trouble removing the bolts as they just wont turn. Is there any trick to this, like ie are they reverse thread or anything like that. All help would be greatly appreciated and rewarded.

Cheers.

They are just a normal thread. I'm assuming you are talking about the central 19mm bolts? The are usually very tight, and a sharp blow to a ring spanner is the best way to free them up. Just make sure the spanner is located properly, lock your flywheel (or put it in gear if still in engine bay) and hit it with a rubber mallet. Either that or get a lever (breaker bar, 2m long street pole, whatever floats your boat), but the short sharp blow is the best option. The flex in the timing assy is disturbing if you apply sustained pressure!

Shudder!

Definately go the sharp blow...

.....or use the hex section on the cam and use an appropriately sized open end spanner or shifter to hold the cam still while you undo the cam gear bolt (with the sharp blow etc.).

Best done with a friend - one for the cam gear bolt and one to hold the cam still.

if it is anything like the 18rg (which it is), i used a pipe wrench on the camshafts themselves
at the front of the camshaft should be a position where you can put the wrench just like undoing a normal nut (it should be immediately after the first cam shaft bearing).
with that on there have a mate/relative pull on it to the clockwise direction, not to turn the engine, just to take the slack.
then you will need the spanner as mentioned earlier, pad the end of it with a rag so you don't kill your hand and fingers when pulling on it (the spanner that is).

damn it, i took to long to draw my picture

i don't know how much luck one would have getting a proper socket and breaker bar onto the front bolt, i think the casting of the head stops you from getting anything better than a spanner in there (definately use the ring side of a spanner though, not the open end.)

Nice one barned01, crystal clear explanation and diagram +rep

[barned01]

virtually the same explanation as you
great minds think alike...


or small minds don't think far apart, i forget which

[tricky]

Oh yeah, forgot they had the hex section Must be at least six months since I've had my celica apart. I've been playing with slightly less well engineered stuff lately . Barned, yep, you definitely can't get a socket onto it, slip ya tube over an open ended spanner.

Anyway, with eight responses saying the same thing, I hope it's somewhat clearer now, andurils_sheath!

I rebuilt mine 9 years ago and I can still remember that

Yes, There is a possibility that I have a degenerative brain condition.

Empirical studies have shown that he who persists with a certain car on which every single part has been replaced is a fool!

Nah, I just think in a different way to most people. Part of it is due to the fact that for the last four years I've been paid to pull apart things I've never seen before and fix them with parts I can't source, hence shutting out things that become obvious when I have to deal with it again.
