Rear spring conversion source

Hello everyone,

Unfortunately on my RMC the airbags havd perished and need replaceing.

I've seen reference on here to being part number AR113 for new airbags and think I may have found a matching wabco part.

If this fails, where can I get a set of rear springs plus caps and shock absorbers from please?

My bus number (if any): RMC1490

Re: Rear spring conversion source

You can try Barnsley, they should have some left, that's probably about all.

Cheers

Rob

My bus number (if any): RM7

Re: Rear spring conversion source

There is springs in Barnsley as I was looking at them earlier this year. However though, will they be ok to use having been sat there for 20 plus years? Shock absorbers will have to be overhauled or replaced unless I reuse the existing RMC ones?

Re: Rear spring conversion source

Shock absorbers for air suspension have different characteristics to those used for leaf or coil springs. Airbags react to the road surface much faster than steel suspension. You must have followed an artic and seen how rapidly the suspension is moving and how little the body moves.

Re: Rear spring conversion source

Rear shocks with air bags are lever arm type if I remember correctly. They were similar to those used on FX4 taxis but bigger. Telescopic rear shocks are available from PSV Partsmaster.

Re: Rear spring conversion source

Yes very Close Roy.

You are correct on the damper type.

Well after no luck in sourcing air bags to fit, I went to a company called Automint in Huddersfield who supplies every type of airbag you can possibly imagine except for AR110 as he believes the mould went missing when it was being moved from south wales back to the usa.

I did buy a type to try out at his recommendation but requires lots of adaptor parts to be specially made and whether it would perform correctly?


So today i've been to Barnsley and bought a set of rear springs and mounting plates.

Unfortunately the RMC will be going all spring but one benefit is I wont have to wait 30 mins for the air to build up in future from scratch!

Re: Rear spring conversion source

Yes, the RMC had the standard RM compressor which was not designed to supply air for suspension at a rapid rate! Speaking from bitter experience of operating 462 for many yer, I'sd suggest you have a good look at the box section and floor strengthening plate at the back riser. They tend to crak up where the bus has been run with the air bags not inflated. It's quite a job replacing it, but I've done it a couple of times now.
