Can I Take The Rb25 Head Off Without Taking Off The Cam Gears?

[ruthless_one3k]

as the title states Can I get it off of an rb25 with out taking off the cam gears. I am thinking of taking out all the bolts and seeing if I can lift up in the back and slide the belt off the front. Does anyone know if this will work or not? I tried taking off the intake side cam gear but it's on there pretty good and I don't know how to get it off. I got the big bolt out but it's still on there tight.

You only need to remove the timing belt when taking the head off. You will have to remove both timing covers and loosen the belt tensioner though

cam gear should come off once you undo the bolt, it just needs some convincing. but no it doesnt have to come off to get the head off unless you wanna leave it attached to the belt on the right tooth

If you have an air compressor and a good rattle gun it will come off. Just need a big spanner on the cam.

BUT - You can remove the head with leaving this cam gear on. Problem is, its harder to get the cam gear off when the head isn't attached to the block.

sounds like thats what I'll do then. I don't plan on taking the cam gear off at all so no need to worry about it being easier with the head on the block and I plan on marking the postition of the belt with a paint marker on all the gears and the belt so it should be easy to get back in time. Looks like I just need to pull the lower timing belt cover off and loosen the tensioner. Thanks for the advice.

best method would be to loosen the tensioner, take the head bolts off, prop up the head from the block by wedging some 10mm bits of timber (or something soft) between them, then remove the belt and then take the head completely off.

the idea is that if the cams move then you could possibly be up for replacing your valves. keeping the belt on eliminates this from happening, and propping up the head stops the valves hitting your pistons if either of them move after you remove the belt.

just set the motor at TDC before pulling it apart and take the belt off last, unless you go cranking it over your not gonna hurt the valves
