I have changed a few of these and there should not be need for any machining. And deburring is just to take down rough edges as Lambert says.
I used a press for the bushings and had no problem installing. Have put in original type and two kinds of offset ones. Hardly needed any deburring either..
I've used my 50 ton press mainly for building rifles. Pressing steel barrels I to steal trunnions or receivers.
The size difference between the control arm ID and the bushing OD was 1.6mm. The bushing have a machined slope to one edge to facilitate pressing. But it seemed a sufficient size difference to justify some reduction in the 1.6mm size difference. Thoughts?
The bushing if course has a steel ring and center separated by rubber. I've never pressed bushings so I don't know what kind of compression tolerances can be expected. But coming from steel to steel pressing it seemed likely reducing one or the others surface might help. I'm not even sure the slopped edge on the bushings fit into the control arms ID. And they seemed adamant it wouldn't press and something would break.
I am concerned that the outer ring in the bushings are now .8mm thinner. But regardless who was wrong or right. I felt it easier to replace bushings later than control arms. If something failed.
Thoughts? Is 1.6mm a normal tolerance offset for a bushing you would normally press? Have the bushings been compromised by their .8mm reduction?
I did some querying on Grok. Apparently the tolerances or interferences I am used to in rifle building are similar to car parts. 1 to 2 tenths of a mm seems normal. And although .8mm is pushing it. It's ok. Could result in a 20% loss of life in the bushings. But will most likely be fine. I'll keep an eye (and ear) on it. And probably eventually just have them replaced with better bushings that fit properly.
I'd follow up with ARB but their support for the Phillipines is fairly non existent. And it's a waste of time with the Phillipines distributor. It's a woman agent with little tech knowledge -who refuses to put me in touch with any tech type person. Not that one probably exists anyway. Lol.
Ah. Life's an adventure in the third world. Lol! It's why I'm here.
Anyone know of a specific better bushing that is in a sweet spot between quality and price?
