Thread: Chassis bushes. 30 mm ?

Dunno, have you? 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!

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

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

Hope this helps ya

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...

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.
