Water jacket stuck on motor...

[animigan]

Big fail here. I'm trying to get my leopard 4050 jacket onto the 4074 motor. I greased the o-rings and motor housing but perhaps not enough. It's on but just barely (not on far enough) and I CAN'T BUDGE IT ANY MORE. I can't get it off to add more grease, or advance it into the proper position...

Is there any easy trick out there?
Thanks,
Andre

If it's that difficult, you have the wrong size O-rings in the jacket or the jacket isn't sized correctly. I've had some 40mm jackets fit better than others on various brands of 40mm motors. Are you installing a Leopard jacket on a Leopard motor?

Thank you, yes - it's the leopard 40mm sized jacket made specifically for this motor (leopard 4074). It went on smooth without the O rings when I tested it...

It's so tight now I can't even get it to turn at all. I tried some lubricant spray on it but of course it doesn't get past the O ring seal.

Frustrating!

Put a couple of screws into the mounting holes. Then gently close vice jaws around the shaft, so you can twist the water jacket without the motor housing turning too.

I will try that, thanks!

also heat expands metal. try a hair dryer on the jacket until its nice and warm then it should be able to turn.

[animigan]

Great, I'll do that too!

Put some oil inside the jacket where the water goes.

edit: I see Larry just beat me to the answer

inject a few drops of some oil and heat the just jacket

[animigan]

Thanks - I'll try some different oil. The only thing I sprayed in there was some "release-all", but that didn't seem to help, even with a big volume of it and lots of soak time. I tried heating the jacket before that, but I'll try the heat in combination with the oil. What oil would you recommend?

Some of these jackets take a lot of effort to get them on. I've had some that take every bit of strength and body weight I had.

Some of the water jackets vary on the depth of the O ring groove, this is on the same make motors along with the same make water jackets. I have had a few jackets that were nigh on impossible to get onto the motor even using oil/grease etc. Where the O ring groove is machined to shallow in the jacket i put them up in the lathe & skim the groove deeper & they then go on a treat & also dont tear the silicon O rings getting them on.

If you do get it off try using dish washing, like Dawn, to lubricate the O rings, super slippery and easy to get off next time

I think he is still trying to get the jacket off. could always call 911.

spray it up with WD 40 let just the water jacket rest on a vice edge in a way your not going to chew it up ,, upright with the jaws open just enough to catch the water jacket and let the motor fall threw motor shaft side down tap the motor body not the shaft with a plastic hammer go back and forth on all sides of the housing never seen this not work
