Hi,
I need to replace the bushes on the front of the engine, the part that bolts the front of the engine to the frame, I tried this morning with no luck, the rubber is really rotten so I have a wobbly ride.
Does anyone know of any tricks or tips to make this easier, I'd like to do it without removing the engine from the scoot if possible.
Thanks in advance, have a great weekend. ;D

I've never done this one but I'm thinking once you get the engine off that a small section of 1.5" pipe and a C-clamp might work to press the old bushings out...

Do you mean pipe that is bigger than the bush housing to set the c clamp to and push the bushing into the pipe?
I am a bit concerned as the rubber is pretty perished that it will, just push the rubber and the inner sleeve out leaving the outer sleeve in place.
thanks.

No, use the pipe to push the bushing in/out as the pipe is about the same diameter.

Actually I was referring to exactly what Sweden was saying but in this event I would consider a second pipe, or washer, or something that is the same diameter as the outer sleeve for the clamp to push on.

If you just have to remove the outer sleeve why can't you split it with a hacksaw to remove it?

Because you have to press in a new one after and I would not trust JB Weld on a structural piece.

Just cut the sleeve, I don't know what I am talking about as far as what sweden has but I have removed sleeves and bushings this way and never had a problim. As far as JB weld gos I agree with you if you cut into the structural part of it.

Okay, I think I know what you're talking about... making the cut from the inside. Yeah, that could work.

So what you are saying is that I could basically dig the perished rubber out ad then put a hacksaw in there, and cut the outer sleeve and then bend it up and drag it out, is that right?
Thanks for all the answers gents.

You got it, but like D-cat said be carefull not to cut into the structural part of it.

you could make a puller with a thick washer the same size or just a hair smaller than the outside diameter of the bushing and a large socket with a inside diameter larger than the bushing. Put the washer on one side of the bushing and the socket on the other side of the bushing and run a long bolt through both then thread a nut on the socket side and tighten the nut until it pulls the bushing out of the motor and into the socket.
You can use the same tool to install the new bushing.

Sockets, I like that; a variety of sizes at your disposal. I'll have to remember that one.

I found a video on youtube the other day where the guy was using something like a socket with a bolt through it on a honda engine, I can't find it again now, typically, to post the link. I will try the socket first and hacksaw second if I end up with the outer sleeve left in, I only have this Saturday to do it as I am hanging up my helmet for a while as I am having a shoulder op and will be off work and everything for 4 months.....might manage another months scooting at the end of the 4 months if the weather holds here!!! Once again, many thanks for your replies and suggestions, they are most welcome.  |

Don't try cutting it out. I did that and it is slow and doesn't work very efficiently. For the second one I made myself a bushing press using two sockets, a couple washers and a bolt. This is the same method that premierscooters and sweden are talking about. It took less than 1 minute using the press. Here is a rough drawing of the tool. One socket is just a tad smaller or the same size as the bushing. This one will push/pull the bushing through the race. The other socket needs to be a bit bigger. As the bolt is tightened the bushing is pulled into the larger socket until it is free. The drawing doesn't show any washers but you should get the idea. To install the new bushing you just do it in reverse and can ditch the larger socket and just use a thick washer. Attachments:

I have taken out bushings and sleeves with sockets also works good. If they are not too tight you can also drive them out with a hammer and socket but be carefull you can beark things or end up makeing it tigher. If they are corroded bad and real tight I have used heat to remove them. I have also has them so bad where I have to torch them out. Like I said before I don't know what you have.
