I have an old Model C rower. I bought a Drive Chain Assembly kit to replace the two pulleys, axle, sprocket, and everything else in the kit.

I remove everything up until the Chain Idler Axle and Pulley. It requires a T-27 driver to remove the second Hex screw. I screw in the T-27 spacer screw, and remove the second Hex screw. Now I am not able to remove the T-27 screw as the chain idler axle just spins.... I need to remove the Chain Idler Axle with spacers in order to replace the old Pulley. I am also finding it difficult to remove the Flywheel axle assembly with the recommended adjustable wrench and 9/16" wrench.

It rows rough, so I am hoping replacing all of this will help.

Any suggestions are very much appreciated, TIA.

There is a trick to those pully screws.

Once you get one out you need to replace it with a longer screw with a nut on it. Screw it in and do up the nut and then remove the hard to get out screw.

Slacken off the nut and remove the longer screw. Thread is 3/16" UNC from memory.

You need two 9/16 wrenches or spanners in combination with just holding the flywheel and letting the one way bearing in it from stopping the shaft turning.

Make sure you put a drop size bit of a thin grease on the flywheel one way roller bearing before running it on the new shaft.
