[QUOTE="Tazza, post: 25453, member: 82"] LOL good 'ol ether fumes Those were my concerns as well, the 642 runs an even smaller engine than a 743 i believe, same frame size though. It still have enough power for what it does, but the newer machines have just that bit extra so they can handle a bit more engine load. There was a gear pump option, but i think from factory they were ALL vane pumps. Throwing a larger pump cartridge at it to an extent i see no problems but there will be bottle necks with the higher flow in some parts, this will cause heat and extra engine load even when you aren't using the hydraulic functions. I'd never say do it, or advise to do it, its your choice if you give it a go, but be prepared for possible problems in the future. [/QUOTE]
