Reinstalling #6 Cylinder

[jakev]

So, I had a broken cylinder head stud on #6. Took the head off that side, removed the cylinder, replaced the two exhaust studs. Now the question is how to reinstall the cylinder. The factory manual shows installing the cylinder with the piston attached to the connecting rod. The ring compressor is between the crankcase and the cylinder. I've tried this and I can't see how the ring compressor gets removed after the cylinder is fitted. A different ring compressor?

The other option is removing the piston from the connecting rod, then using the ring compressor, installing the piston into the cylinder, reattaching the piston to the connecting rod. As I am working on cylinder #6, it means removing the other cylinders on that side to access the wrist pin. This adds more time to the procedure.

Is there another method? I have considered removing the intake cylinder head studs to facilitate removal of the ring compressor after the piston is in the cylinder. But, I don't know if there is clearance for the ring compressor.

Any suggestions as to what method?

By far the easiest thing to do is just use the correct ring compressor so you don’t have to remove the piston. Hazet 794U-3 is the best but there’s a couple others that will work as well so you don’t have to remove the piston

You could install cylinder #6:

• Piston installed inside cylinder #6.
• Or piston installed to the connecting rod.

People who had attended the Engine Rebuilding Workshops had done and practiced this particular task many times over using the right tools. Install the piston inside cylinder #6 or the piston to the connecting rod. Both methods work and use the appropriate tool/s.

It is a lot easier and convenient to install the piston with rings and set the correct piston ring gaps on a work bench. I tried both methods and prefer the piston in the barrel/cylinder method.

I have used a ring compressor like the one below for situations like you are describing.



For fresh build I find it much easier to install piston in cylinder and then install them on the engine.
