Re: install of new engine

The hardest part of changing/replacing engines is getting the electric clutch/pullys from the old engine, you may need a pully puller. Most of the time the pullys come off with no problem, screw driver or wrecking bar usually brings them off. The rest is just a matter of disconnecting and reinstalling gas line, wires and t-cable. Don't forget to tighten all bolts and put oil in the new engine before trying to start it. Some people do forget to do this. Good luck.

Jeff, if you need a pulley puller, most rental places have them for rent.

If you are replacing the engine with an identical engine, it should be fairly easy. Not that different engines are hard, but sometime slight modifacations have to made. One then to check the new engine is mounted is proper belt alignment. This is easily checked with the belts install by looking at the belt from pulley to pulley. They should be staight runs. If there is an angle, then pulleies will need to be repositioned. If not, belts will not last as long and you will loose some horsepower and erode the pulleies. Another way to check true alignment if there is room is to use a straight edge and lay flat across the top of one of the pulleies, the straight edge should parallel the belt. If the straight edge is long enough to lay across both pulleies and the pulleies have the same thickness, then the straight edge should lay flush across both pulleies. It doesn't have to be exact, however the truer they are the better.
