How bad is to ride with dead engine bushings?

[katt]

 

I think my bushings were dead before could have killed them some more doing tests today basically this is how much i can move engine with my hand, will it not damage anything if i ride like this (6 hours a day) for few days while waiting for replacement bushings?

Someone got link to buy bushings that go inside the motor mount itself?

[milly]

Yes most likely you if anything snaps and you loose control.
Sorry the only links I have for parts is in the U.K. here.

Is it those bushings or the big one on the dong at the front that's worn?

[katt]

One in on the dong can rotate by fingers when i lift up engine and a big piece broke off of it, other bushings inside mount are way off the center and one inside crankcase have big cracks visible.

I like to lean to the side somewhat when making a 90 degree turn on the stop light and just when road curves so i need to take care of this, also when i use rear drum brake i feel jerking sometimes it could be related.

Since no one sells bushings for the mount itself at least i have no idea where to find custom size bushing and new motor mounts are out of the stock in stores at moment i have decided to try this and repair them as seen in this video.



There is also nice video on how to make your own with mounts that i want to try out of curiosity.

If you measure them, you can prob find something. I don't think most ever replace them. Prob replace the whole mount if needed.

Let us know how it goes with the DIY bushings.

I don't mind new engine mount, except they out of stock everywhere i checked.

To put long story short here's what i learned about bushings, factory made universal polyurethane bushings on sale are all into sport category (stiff) versus rubber ones (soft). Liquid urethane can have any level of stiffness even softer than rubber.

Even aftermarket rubber bushings are stiffer than OEM rubber bushings (for cars, chinese scooters probably already had cheap stiff rubber bushings), more stiff it is less damping it provides simple as that.

I wanted to try making my own but i cannot wait 1 week because its how long it takes to cure some of this mixes.

Just ordered a set of pre-made rubber ones i might still try when i remove the old ones and have a old shells to play with.

Whats it called here's a temp fix for the middle bushing, just tossed it and used a electric tape.






Another issue i found out is receiver for that bushing had broke off the frame and only holds on one side, dunno that's due to excessive movement due to broken bushing or because weld rusted.

Changing 3 crankcase bushings engine mount dong improved handling stability, still got to change engine mount and rear shocks bushings, and one in metal plate holding rear wheel.

katt, have you tried the diy bushings yet? If so, how did it go?

I've got to do All of mine. The Cyprus has an odd mounting arrangement with four bushings and a heim. The Helix, hell idk, and them the three for Junior when he's up and running. I'd like to try my hand at making a few sets as well.

[katt]

I did not go with DIY mainly because i had to make money doing deliveries and it takes 7 days for this stuff to cure. Just purchased new bushings and did quick swap in few hours, the pretty soft as well.

Don't forget to get 2 front and 2 rear bushings for the crankcase.

I was bit concerned when i seen the rust at the sleeves of the bushings and thought they rusted all way and will not come out without a fight. Since crankcase is aluminum i did not want to break them and used a metal saw to brake the sleeve.

Basically i cut 90% of the sleeve in 2 parts then used screwdriver to tap on the sleeve with rubber hammer until it started to fold inside and by the time i folded it about half way bushing started to come out loose.

Section of bushing sleeve that touch the crankcase was not rusted at all, it would come out okay if i tried to extract it.

I don't recommend using saw unless you absolutely have to and then be very careful, second bushing i cut a little bit too far and went onto crankcase just slightly.

I sell those bushings...


Also the case bushings...


Sorry if I came to the forum late... haha whoops

[katt]

I am all set now, perhaps put it on for sale section. Still need a new engine mount, tried to extract old bushings and it is close to impossible to do guess because they are like 60mm long.

Came across this center bushing it seem like it has a metal sleeve dunno if that an aftermarket improvement?

Perhaps i need to order some motor hardened ones because i got this one and it fallen apart pretty quickly in 2000 miles or so.

Yes you should replace them as soon as possible , have you ever seen a rear tire on a scooter that is worn out on the outer edges of the tire and the center is good or the outsides are cupped . That happens when your engine mount bushings are gone that is how you tell if your just doing a visual on the scooter be for you even touch it ! IF you can't find any bushings and you need them like yesterday do this . Take the engine mount off go to your local offload store 4wd store and look for a neoprene bushing that will fit your mount a lot of them are 6" or more long you can make two and cut the inner sleeve down
and your good .. Just get all the measurements and go for it . I did this once for a three wheel scooter cause i could not find the right size and it worked for two years nice be for the scooter got stolen !
