Looking back

Looking back I have to wonder how I ever managed to take the engine out of that VW, rebuild it and get it all back together considering my lack of experience and limited tool box.

Specifically I have to wonder how I ever got the pistons back into the cylinders without a ring compressor, but I know I did, which led me to try it again with the Honda.

"How'd that go?" you may ask.

"Not too good." I'd reply.

I mean I didn't screw anything up, but I couldn't get it back together either. I probably would have screwed something up, but realizing as I do now that parts for this machine are rather hard to come by, I wasn't willing to push my luck too far.

I put the rings on, hooked the pistons to the rods and tried to balance the cylinders over the pistons with one hand while trying to compress the rings and work them into the cylinder with the other. You probably already know that doesn't work and once I got the first piston @ half way in I started thinking about how was I going to even possibly do the other side considering I'd only have about half the room to work with. So wisely I stopped and went out to buy a ring compressor.

When I opened the box I was faced yet another problem. All ring compressors aren't created equal and the one I just purchased, while it would definitely compress the rings, it definitely wouldn't get those pistons into those cylinders while they were attached to the connecting rods. It was wider than the rod was long. Furthermore, if I got one piston in there was no way to get it off afterwards as it was a closed circle in every shape. Furthermore, with one piston installed it was too big to fit over the other.

So I looked online for some words of wisdom. I found a picture of a guy using a very similar ring compressor to put a piston in cylinder. The big difference was he was working on a one cylinder engine. Every one else was using a specialized tool, which I found I could order, but then I'm waiting again.

With the tool I had the only way to do it would be; put the pistons in the cylinders before attaching them, then try to balance all that while getting the wrist pins and circlips installed. That didn't seem too likely, but the alternative was to return the compressor I had, order the specialty tool and wait.

I decided to give it a shot.

It was kind of tedious and a lot frustrating trying to hold the rods still with one hand while balancing the cylinders with the other while trying to slide the wrist pins in with...what? And I managed to not drop either circlip into the crankcase while installing them, (I plugged all the holes before starting)

I'm pretty sure the purists would say "you did what?" And I know that's not the way to do it but...

  1. CBMMA. If it gets the job done (without screwing anything up too bad), it is the right way to do it. Keep on keepin' on.
