Hey guys I have a few questions about removing the rocker arms on a 6G74.


1. In the workshop manual it shows a special tool E9M40-2. Is this necessary or is it so the lifters come out with the rocker arm assembly?

2. Am I correct in understanding that the torque for the rocker arm bolts is 31nm?

3. My lifters do not tick, though since the rocker arm assembly is coming off, should I follow the "Lash adjuster cleaning and checking" guide in the workshop manual?

4. Anything else I need to keep in mind when removing/replacing the rocker arms, other than to put everything in the place it came from?

I never used a special tool to remove the rocker arms or lifters.

The lifters will sometimes just drop out so you need to be careful not to let them fall into the motor.

Rockers arms are 31nm.

How come you are removing the rocker arms if you are not doing anything with the lifters/hla's?

I would still give them all a good clean out in diesel while they are out.

I am planning on changing my valve stem seals, not remove the lifters but since going this far into the valve train I was wondering if there is anything else to keep in mind.

What do you mean the lifters could drop out? I thought they were stuck in the head and need pulling to get them out?

Removing the rockers without losing the lifters? Get a helper and roll them back. Plug all potential holes before doing so.

Installing rocker arms without losing the lifters? I used 2" wide silk ribbon to tie them in while out of the car. This holds them in well enough to get everything positioned in the car, then you untie the not and slide the ribbon out. Works well, I know I replaced my lifters this weekend using this trick. No lost lifters, no sweating bullets over losing lifters.

I could "draw" up the part you're talking about. I think I may have already. But, the roll of ribbon was maybe $3.

Rocker arms have the hydraulic lifters in them. Lift the rocker arms and the lifters drop out. The tool is a simple piece of spring steel "U" shaped to slip over the end of the rocker arm and keep the lifter from dropping out. You would need 24 of them. Can use masking tape or ribbon to do the same. Once off, flip the rocker arms & shafts upside down. Shouldn't leak oil out, hopefully.

I see, I always thought the lifters would stay in the head. Seems I need to do more research

Yes, some head designs have the hydraulic lifter in the head, usually as the pivot point at one end of the rocker arm, with the valve stem at the other end and the cam on top at the middle. Better idea really, since it reduces weight of the bits moving. Then again the 6G engines aren't high revers.

I think I also have a DOHC setup pictured in my mind. Not really sure how the SOHC setup works as far as lifters are concerned.
Luckily I have a spare set of heads which I was going to get some practice on before trying it on my car

Guys another question in regards to removing and reinstalling the rocker arm assembly.
Does it matter at what part of the rotation the motor is at when removing?

I was reading a how to on removing the rocker arm assembly for a Toyota and it said to make sure Cylinder 1 is at TDC of the compression stroke? Why would this make a difference?
