Chassis bushes. 30 mm ?

[Kimsl70]

Hello all,

I’ve removed my old chassis bushes, upon going to install the new ones (not polybushes) I’ve discovered the chassis opening for the bush is closer to 27mm. The new bushes are 30mm. I’ve measured it with a micrometer to confirm.

My questions are;
A. Did the early series 2 have different bush sizes ? Or have I inadvertently ordered/received the wrong bushes ?
B. Have I stuffed up and only removed the inner sleeve and bushing of the old bushes ?, and do I now need to carbon tungsten de-burr the hole the outstanding 3 mm ?
C. Polybushes? Anyone have any horror tails ? Or should I bite the bullet and just get them ?

Thanks in advance for any help

Cheers

Dunno, have you? [emoji23][emoji23] how many steel sleeves did you pull out? After getting the inner case out then removing the rubber, did you pull the outer case out?
If not you have to make a relief cut with a hacksaw then punch and hammer the sleeve out, you can make more than 1 cut to make it easier but be carful not to cut the chassis!

Cheers. I guess that’s more grinding out for me. I really appreciate you taking the time to measure that.

As u can see from this pic of 2 broken front springs the bushes have 3 parts. A steel inner tube or spacer. A rubber insulator, and a steel outer tube. I suspect u have removed the rubber and inner spacer and havent removed the steel outer tube from the spring or chassis. The holes in the spring and chassis are approx 30mm +/- a few thousands of an inch. If ur holes are 27 mm then thats about the size of the inner diameter of the outer steel tube. After u have replaced the spring bushes in the springs and chassis, (chassis bushes are hardest to do), dont forget to leave the bolts loose until the weight of the vehicle is on the springs. Bounce it up n down a few times and then, with the weight still on the springs, tighten the bushes, or they will fail very quickly and u'll have to do em again.

Ps...only pic i could find. I have others somewhere but not on my phone...[emoji41] https://uploads.tapatalk-cdn.com/20190111/212105e7e715c106f1132dea3a20121c.jpg

Thanks Rod. I really appreciate the reply. I think I’ve inadvertently left the outer sleeves in. So it’s back to grinding for me.

Clean out the hole with a flappy sanding disc roller. But dont take too much metal out. Fitting bushes in the spring is easy coz the spring is split and will spread open a bit when they are fitted. The chassis wont at all. Really good fun. I know.[emoji41] [emoji41]

Chuck em in the freezer so they shrink (apparantly) bit of a wives tale but ive heard it a few times.

Use plenty of Graphite Grease, Coppercoat, Antiseize, or something similar.
It makes it a dirty job, but far easier and better for the next time you have to change them,
as this set won't last anywhere near as long as the originals did.
Make sure you let them settle in for a week or so too, drive a few kays etc., before you nip the bolts and lock nuts right up.
Otherwise the new bushes with be history in no time at all.
The right "choice" of words and in the correct order, can help with the installation of some of the harder to get on with chassis bushes. ;)

As Rod said above...Have Fun ;)

Cheers, Mick.
