4age 16v camshaft removal

[levinguy]

hi,

im pulling apart a 4age bigport at the moment, just to learn a bit more as i no nothing

at this point in time it has no cambelt on and i have taken the all the caps off

i am stuck as to how i should go about getting them out without the cambelt on, as i cannot get the cam gear bolts off.

how do i go about getting them off? preferably without taking the gears off

also i was told and i did take the caps off in a certain order loosening them as i went. what is the point off this? and what would happen if i did not do this? just out of interest

thanks

Point of taking them on and off like that is so its basically pushing the cam down as a whole rather than hard down at one end etc which would twist things and stuff. Worst explanation ever, but you get the idea.

Should just come out once the caps are off. Give it a bit of a lever with a screwdriver and see if it pops out

you will have to take the camwheels off. Did you mark top dead center before he cambelt came off?
With the caps they need to be undone/done up evenly as they tend to go on a angle, few turns each side etc.
once the caps are all off and cam wheels off(so much easier when marked fo putting the back together!) the cam should come straight out. If may need a wedge though

hope that helps

to get the cams off now you hold a screw driver thro 1 of the holes in the cam & wedge on 2 something then undo the bolt

did not mark TDC, thought there was a mark on the camwheel that you can line up with the side of the head? or am i wrong? cambelt was off/proberly snapped when i got the engine

have been told to put the cam wheel back on straight after in the right spot or to mark where it goes on the camshaft

and for using a screwdriver have tried just now, and no luck. where should i be jamming it? im proberly to scared to put to much weight on it when i am jamming it.

where you located?

you may have to take the backing plate off the head so you can take the cams out easily. i bet that's why you can't take the cams out. Had this trouble with my ae92 , just take camwheels off (which you've done) then unbolt the backing plate, 7 bolts and they come out. Maybe a little stuck in the end cap as they usually have sealer in them which makes it a bit hard to take the cams out. If you lever the cams don't lever against the head as you'll foul the gasket mating surface but you'll need a rather large lever and don't lever against the cam lobe (shiny part of camshaft. ) you'll damage the surface of it

i thought the camshaft had a machined hex between 1-2 piston, so you can put a spanner onto that and undo the pulley bolt??

[levinguy]

i havn't taken the cam wheels off thats my problem,
theres nothing stopping the wheel and the whole cam from turning

i was told to use a screwdriver but where abouts is safe to use it?

sorry if im hard to understand, im doing my best!

[Brick]

once you got the cam wheels off, take the 10mm bolts out of the blac matal guard thing here

taht will makeit easier to get the cams out.

you might be lucky and get the cams straight out, other wise if your going tolever it out make sure its no where important

[levinguy]

got it

pretty simple once i realised

thanks for the help everyone!

Theres a hex on the cam a bit down from the cam wheel.
Put a cresent or spanner on that amd hold the cam while trying to undo the cam bolt

have only been inside one 4ag, so am happy to be corrected. Toyota were usually pretty good at designing gear that was easy to work on, hence the reason why it's reliable in a standard form.

Another way to get the gears off is to get somebody to hold them with a big $&#$% off set of polygrips. In fact almost any automotive problem can be solved with big polygrips.

& a big hammer can also fix any thing

if it dousent work hit it with a hammer if that dousent work get a bigger hammer
