Engine Builders! Looking for some tips

Hi All,

I am currently in the process of rebuilding my first rotary engine. A series 4, 6 port. I bought this engine to learn on so when the time comes, hopefully I can rebuild my Turbo II myself.

So, in the interest of working smarter not harder does anyone have any tips/tricks on cleaning the engine components? I should have done a better job cleaning the outside of the engine first but as it sits everything is disassembled and needs cleaning. From the outside of the irons to the oil drive components any tips for cleaning would be appreciated! Looking for cleaning solutions used (parts cleaner?)/tools/brushes/anything.

Also curious if there are certain parts I should NOT clean a certain way. For example, would a heavy degreaser/parts cleaning solution hurt the face of an iron?

Aside from cleaning if there is anything else you guys have done to make an engine build go smoothly feel free to post it!

Buy a harbor freight parts washer and a brush and go to town. I loaded mine up with simple green HD and its worked great for a few rebuilds.

I like having the brush the connects to the nozzle with a hose so the de-greaser comes right out of the brush.

I used a plastic tub (wheelbarrow) filled with Simple Green and water. Use minimal contact time with the Aluminum housings as the simple green reacts with them. I just clean them quick to get the grease off and then rinse them off with water. I usually scrub the irons/rotors with a stiff wire brush and even some drill mounted ones too. All the steel stuff can sit in the simple green solution for as long as necessary. I usually do a quick scrub and return them to the bath for a few days and repeat as necessary to let the solution do the work.

In regards to the brush with the hose I could see hooking that up to a cheap aquarium pump to replicate a parts washer without having to buy one.
