lifter notch and shim replacement tool

Postby toycort » Thu Jul 13, 2017 10:13 pm

I have a head that has only 1 notch in each lifter, is this common? All my other heads have 2 notches 180 deg apart. I assume the notches are for shim removal. Would there be any negative affect on adding the second notch?

Does anyone know of a source to buy the lifter compressor/shim removal tool? I have not been able to locate one.

That is what I use and it works great.

Thanks, I have one of those. I was looking for the tool to compress the lifter to allow the shim to be removed.

Just figured out how these tools work :)

Image

The tool like a pair of pliers is used around the camshaft (not the lobe) to bear
down on top of the shim and force the bucket and shim to move down...

Image

Then the other tool is used to get under the camshaft and hold the edge of the
bucket down (not pressing on the shim). Put the plier tool to one side as it has
done its job.

Image

Using a small flat blade screwdriver, place it in the cutout on the edge of the
bucket (and you already turned the bucket so that the cutout is facing you),
and apply firm pressure to the bottom edge of the shim. It may take a few
seconds to break the suction of the oil film holding the shim onto the bucket,
so don't get agro :)

Once the screwdriver has slipped under the shim, use a "magnetic finger" to
grab the shim and pull it out. Best to have the replacement shim handy so that
you can slip it into place while you still have the bucket held down.

When the cam lobe is no longer touching the shim (lobe pointing up) the bucket
is easy to spin around and get the cutout facing where you want it. So do this
before starting on each shim.No way would I be trying to make a second cutout.

Have to say that I have never used these tools, as I have always had to shuffle
shims around to set the clearances, and pulling the cams just seemed easier.
But now that I have figured out how they work, I'd be tempted to try these if
I only had one or two shims to change.

I have to agree with Jondee86 when it comes to holding down the lifter buckets. It is a PITA to hold down the edge of the bucket the tool. If you have more then a couple shims to adjust, it is much easier to lift the cam. If you do not have to adjust the front valves you can actually leave the belt on the cam gear while replacing the shims. Dave W
