How to install generator mounts

[flying kiwi]

Can some one please tell me how I can lift a 12kw northern lights generator from underneath so I can replace the vibration mounts?

You should be able to lift each corner and do them one at a time. Maybe a small bottle ram and a pry bar?

Thanks for the info. Unfortunatly the one that has failed is the one next to the oil sump and I can't get a jack underneath any where around the area. Has anyone else got any ideas? Thank you.

Kiwi, is there any lift point, a bolt or ring, on the top of the genset?

Some folks have used a beach ball, soccer ball, basketball, old inner tube, as an air lift bladder. Let the air out, slide it under, inflate to lift. There are real lift bladders sold in auto shops, to be used instead of car jacks, but they tend to be way more expensive. A hand pump putting 50 lbs. of air pressure in an old inner tube, multiplied by the area of the tube, can lift a lot more than you think. Just make sure to slip some blocks under it, so you don't crush fingers if it deflates in a hurry.

An inner tube sized to fit a trailor tyre will work provided one can stabilize the machinery so that it cannot slip out of alignment. If the space under the generator is not horizontal, level it with loosely filled sand bags filled with kitty litter. As the weight of the machinery comes on, the material will compress and become quite immovable and, later kitty litter is easier to vacuum up with a shop-vac than is sand et al.

FWIW s/v HyLyte

Thanks very much Hellosailor and svhylyte. I will try that.
