Bought this trashed 1978 CX. It appears to have been stolen probably in 1979, then dumped at a NYC river (gross back then). The registration stickers say 1979. The odometer states only about 1400 miles. After having washed off construction dust (from sitting in the garage of a building undergoing renovation), it smells like a sewer.



The cooling liquid is bright green. Is that good? What did cooling liquid look like in 1979? Can I use it again and add water or is it too old?



The oil came out pretty clean, but not using that again.



The rubber hoses had to be peeled off everything. Used a thin screwdriver. And now trying to get the rear engine cover unstuck. I want to get the stator from it and use it in my 81 CX500c. Either that or just use this experience for when the 81 engine comes off.



Do I use a razor and go around the gasket?

Also thinking about putting an extra coat of resin or something else insulating on the stator windings before re-installing. Any suggestions?



Planning to restore this engine and maybe design a new frame for it -- one where the engine does NOT have to be removed to service the alternator!



Oh yeah, I took this pic before removing the impeller cover. Can't get the impeller off either! Everything is stuck, except the shifter, as if it's all rusted inside. Do I have to remove the pulser stator too?



Thanks in advance for everyone's help!

Get a copy of the shop manual and follow the procedure as stated.

Have the manual. Didn't see anything about stuck rear engine covers. Did see about removing the pulser stator, though that's not the problem.

You need to remove the Water pump cover on the rear top of the engine and the water pump impeller before you can remove the rear case.Definitely read the manual if you are going to strip and re-build the engine.Better to get a hard copy manual off Ebay/Amazon

if possible so you can sit and read.Helps big time even when you know the engines.



My 2 cents.

A small puller would be a good investment here to remove the impeller. A liberal dose of wintergreen oil on the impeller/shaft joint and let it set for a day before pulling. Wintergreen oil can be purchased at most drug stores.

How about Deep Creep? (pure petroleum that foams)



And what about breaking the seal? I finally got a rubber mallet, but it's not budging. Anyone else have gaskets glued tight?

Pm sent.

PB Blaster? Foams and penetrates.

 

[Shep]

They can be glued hard but also be certain you have removed ALL the rear engine bolts and the Water Pump impeller?

i think you will find its the location dowels that are the issue,i ended up...grinding down a 3/8 wood chisel to 10 degrees,then nibble away at the dowel locations.

very slowely,tap away.you need to vibrate the joker off.....but dont rush

 

[Randall-in-Mpls]

I use an old fillet knife. It's not very sharp anymore. But with its square spine to tap on, it makes a good wedge. Just remember the dowels are there, so don't tap too hard or too deep.
