Rear suspension bushing

tom.langborg · 01-01-2009, 03:06 AM

Hi
My Weltmeister bushing docent fit so well.
The bushing outside is to big to fit in outside holder.
The bushing is 75mm in outside and the hole is 73.5 mm.
I think that 1.5mm is to much to compress.
What is your experience?
I have not take apart the other side yet.

regards
tom

If they are rubber (neatrix), then keep pushing, they are the right size. Use some silicone lube to fit them a bit easier. If they are hard plastic, I can't answer as I've never used those.

Use longer bolts in the bracket to force fit it in. You might need several sizes. Start with 2 long (enough) bolts. Screw then down to their max which will force it in aways. Then use another smaller length & bolt it down to it's max & repeat etc until you can use the stock bolts.

Tom,

I had the same issue with my Weltmeisters. You have to force it.
Do you have any clearance at the inner diameter around the spring plate tube? If so, it will be picked up when you press it into place. Make sure you scuff the bushing surfaces and slather it with silicone grease to keep them from squeaking as much.
I used a belt sander to reduce the outer diameter until it had a snug press fit.

Good luck and Happy New Year!

Hi
Thanks for yours inputs.
Bushing looks that the are made of some type of plastic material.
I have some clearance at the inner tube. I think that i need to reduce the outer diameter before.
I think the best way is to press the bushing on the outside holder before assembling the rest.

Thanks guys and have a good new year with your cars.

To,
+1 with the above.
Reduce the outer dia. if needed, file the edge at an angle of about 15 deg. to get a lead, use Silicon grease, press the bushing in half-way and see how the shaft fits on the inner diameter.
If the fit is good on the shaft with the right clearance, push the bushing into the housing all the way and continue.
Use Silicon grease inside and outside of the bushing.

Consider pulling the torsion bar out, lube the splines with bearing grease and re-install.

I installed a bump steer kit during the same timeframe of my Welmeister bushing install on the spring plate assembly. I found that the original steering rack bolts that were removed as part of the bump steer kit were the exact size (diameter, pitch, length) that I needed in order to start the bushing spring plate covers to be pulled over the new bushings - just like Ian (imcarther) mentions above. No resizing/chamfering of the bushings is required - but a little grease doesn't hurt.

I once installed a set of those. The proper way is to turn them in a lath to fit. Having said that I sanded the OD on mine to get them close and then forced them in. This made the inside diameter to small so I took a barrel sander and opened up the ID till the arm would fit without binding. This an inexpensive track style bushing. They are known to be a bit stiff and sometimes squeak so use the Weltmister lub that is made for them.

Next time around I went with the Neatrix rubber / stock style bushing.

Most on this board worship at the church of Elephant Racing, Polly Bronze Bushings so I would not be surprised it you don't get beat up over the Polly Weltmister bushings.

If you have to force the springplate together when using plastic bushings, you're not going to be happy with the result. You need a bearing like action with the plastic, or they will bind, squeak, and give a harsh ride.

It's O.K. if the bushings are tight in the chassis, and the spring plate cover, but once these are in, the bare springplate should easily slide into the bushings. If not, you're going to hate the results.

With the rubber Neatrix, tight is fine, since the rubber actually twists during suspension movement just like the factory bushings. These are much more user friendly to install.
