so lately i noticed that the big bushing in my cases for mounting the engine were completely torn, and causing my rear end to toe left and right and was very unstable and unsafe. so i ordered what i thought were new bushings, after recieving them i took my motor off only to realize what i got were the bushings that go in the metal bracket that connects the motor to the frame... those were not ripped and what i really need are the bushings that are in the cases... i cannot seem to find them online. i read something on a forums about a guy using a bearing in place of the bushing to make it a more solid mount, and i am all for it but i have no idea what size bearing to use... also im pretty confident i cant even get the old bushings out to replace them without cutting them and mangling them up. has anyone else had to deal with these? its starting to become very frustrating because i want to get it straightened out, the weather is finally nice and my scoot is in 100 pieces lol

Not sure if it's exactly the same in scooters, mine all use bearings, but the ATVs with minarellis use bushings. Here's what came in the ATV engine I bought...  If that looks like what you need, I think it would be #3 on the diagram at the link below. Polaris part # 96400-233538 . www.powersportsplus.com/parts/search/Polaris/ATV/2003/A03KA09CA+PREDATOR+90/ENGINE+BRACKET+-+A03KA09CA-CB/parts.htmlHere's a pic of the bearings swapped into that same engine pictured above.  Gimme a minute and I'll run out and see what number the engine mount bearings are. EDIT : 6003-2RS If you plan on keeping the same mounting hardware, you might need to use a different bearing with the same OD but smaller ID to match what you use to mount. |

And....... let me add: it really isn't a good idea to wail away at these things with a hammer..... you would use maybe a combination of a big "C" clamp and socket, or maybe a ball joint press, you sure wouldn't like to trash a set of cases with a hammer?

A long piece of threaded bar with a nut and washer on each end is the least violent way of doing it.

1fastqmb - in the picture those look about right, but in the description it says gy6 and kymco mounts?... i dont know if they are the same? 90GTVert - i cant view those images on my phone ill check them on the computer when i get off work today... i tried to take them out the other day by using a long bolt with the biggest washer i could put on the ends and tightened it with a nut and all i did was suck the rubber inwards since i cant get the washer to hit the outter metal ring... it seems pressing these in will be 100x easier them taking them out... i may have to cut the rubber out and then use a dremel to cut through the outter metal ring and then bend them inwards and pull them out... but before i do this i want to be 100 percent sure i have the proper replacements... 90GT- when you talk about what mounting hardware i use, i plan on using the stock steup.. i think tritons are a little different them zips.. theres a box type bracket with two mounting points, one to the cases and one to the frame.. the bracket goes in between the case halves and just the bolt itself goes through the engine mount bushings... i am open to either using a new rubber bushing or getting ball bearings al long as i know what i need to make it work right

nope its nothing like that. mine is a welded steel box with two mounting points in between the engine and the frame. it goes directly around the reed cage and gets in the way of everything. but the bracket itself does not go through the engine mounts, it merely fits inbetween them and the long bolt goes through it and the mounts all at once, and then it sort of pivots between the case and the frame. i will get pictures today.

the bracket im talking about actuall has its own bushings and when i ordered what i thought were new bushings for the case they turned out to be the bushings for this bracket(which are useless to me because those are in good shape) all i need are the bushings for the cases

I ended up separating the rubber from the bushings so I used a chisel and dug into the steel shell while hammering so the bearing would move out. Just have to be really careful not to cut all the way through the shell and chisel the aluminum case. There's prob a better way, but that worked for me.

2strokd - sorry, I tired viewing the pictures earlier while i was at work in the link you posted on my phone and i must have been looking at the bottom engine in that picture, plus it doesnt help that my phones screen is rather tiny and the sun was shining directly on my lcd lol.. that is defintiely the mount i am talking about. Basically the bushings that are in the pictures that 90GTVert posted off the ATV engine are probably the same outside diameter as the ones I would need where they fit into the cases, but those have a bigger inside diameter because there is a tube of sorts that ruins the whole way through both ends.. with my setup the tube is part of that bracket and just the bolt itself goes through the center of the bushing... I dont know what size bearing i would use to give everything a snug fit, not to mention that the bearing would most likely be narrower so I would have to shim that mount with some washers on each side to keep it tight and centered.... i wish I just knew where to buy those bushings.....

90GTVert - Did you switch to those ball bearings that you posted of a picture of? How snug of a fit were those when putting them in the cases? I would think youd want it similar to the way the crank bearings are fitted, maybe slightly looser, but not much...
