Engine Installation and Head Installation

With the engine assembly mostly done, I wanted to get it installed into the frame. The frame was a rolling chassis and was ready for the engine to be installed. I decided to not install the head as without it the engine was a managable weight I could handle alone and wouldn't need assistance to install the engine.

I began by masking the entire right side of the frame of the bike around the engine area. I didn't want to scuff up the powder coating and althought it is tough I wasn't going to take chances. I also dug into my bag of powder coated parts and found all of the newly coated engine mounts and all of the bolts. I cleaned up the chrome bolts and prepared to install.

The most difficult thing about installing the engine besides the akward weight, is to get the shaft drive to mate up with the engine. I prepared for this by liberally greasing the u-joint and ensuring it would go onto the drive, and also by placing a jack under the bottom of the engine to be able to adjust the height. I then moved the engine into the frame and set it on the jack below, and began to maneuver it into proper position. Once the drive shaft is mated up properly, the mounts can be installed. I did the front two first and then the rear upper and then both loweres. This process took about 45 minutes start to finish, and in no time I had the engine installed. Here is a photo of the finished process. Notice the head gasket partially installed.


Next I needed to install the head. I first cleaned the mating surfaces of the cylinders and head and then placed the head gasket in place. I then put the cam chain guide into position and finally lowered the head into place. It took some doing as the cam chain guide is tricky, but once it dropped into place the head mated up and I was all set. The picture below is of the head in place just before bolting it down.

There is still work to do on the head such as adding the lifters and camshafts and all of the other small parts. That is my next task when I find time in the garage.
