Update on my hi-miler Z project - Page 23 - ZR-1 Net Registry Forums

I met Kurt this morning (heck of a nice guy, BTW). We exchanged my old motor for his new one, and I was on my way back home.

Cam cover bolts removed, masked off for paint:

First coat of paint:

Since I've been running with the Secondary Port Throttles deleted, I needed to perform the deletion procedure on the new heads (which definitely ARE new!). I took some pics of the process, for anyone considering doing the same on their own motor:

Here you can see the throttle plate, and I'm using a vise-grip pliers to hold the magnet end of a telescoping retrieval magnet. All of the materials (plate, shaft, screws) are ferrous, so the magnet is a little insurance policy against losing anything down the intake port. The screws are a T10 torx.

Once the screws are removed, and stuck to the magnet, the entire plate/loose screws assembly is carefully lifted up via the magnet.

Next step is the removal of the throttle plate shaft and bearing assembly.

View of the shaft, in the intake port

View of the external portion of the shaft

A socket is fit over the threaded end of the shaft (I used a 5/8"). The key is that the hex end of the socket must be large enough to accomodate the bearing as it's pulled out of the cylinder head, yet small enough to fit flush on the flat surface surrounding the bearing.

A fender washer is then placed over the threaded end of the shaft that protrudes through the square end of the socket

The actuator arm nut is then threaded back on to the shaft, and carefully tightened against the washer, which will then pull the entire bearing assembly out of the head. A needlenose pliers, with a rag or towel as cushion, is used to grasp the throttle shaft to prevent rotation.

Done! 7 more to go!

Might take me a little longer than that to get everything all squared away... Heck, it'll kill a whole day to finish painting the cam cover lettering

Great time for a stainless bolt upgrade.

Yep, actually already had them on my old motor... transferring them to the new one after paint is done. =D>

Awesome bro don't hurry or rush your almost there. GC

Daryll, no rushing here -- gonna possibly be held up for a while until I can obtain a tool to install the harmonic balancer on the crank. Anyone have one they'd be willing to lend or rent?

The brotherhood comes to the rescue again -- Phil (Jagdpanzer) is going to lend me his installation tool! Thanks Phil!
