Can the 5" backing plate for the Rupes Mark II LHR 15 be purchased separately?
 
Is the backing plate different on the new mark II series?
I am only finding the 5" backing plate for the Rupes LHR 15ES.
They might be the same?
 
I heard from another thread that they don't sell the mark II backing plates separately yet.

And I don't know if the mark II 21 and 15 backing plates are interchangeable. I'm assuming they are.
 
First batch of MKI have the rounder dime size hole and will not fit the newer Rupes. Later generation of MKI have the identical hole as the current MKII.

Correct. All backing plates are backwards compatible.

The original run of ES tools had a smaller slot in the backing plate and spindle key. While the first run of the ES tools will accept any backing plate, their original backing plates will not fit the newer tools.

Best news I've read all day.
 



Old 5" on the left, new 5" on the right

Technically the one on the left would be OLD OLD - that was original OEM equipment on tools manufactured before July 2014. After that they featured a more oblong pin engagement like is pictured on the right, but with the blue ring. The one on the right would be the very latest generation that comes as standard on the Mark II tools. Oblong pin and gray back.
 
Would there be any useful purchase to upgrade your old backing plate to the new version? Basically, what improvements did Rupes make in their new backing plate?
 
I believe they changed the hook and loop to have more Radial strength while decreasing the tear strength . Basically stronger for the stresses the machine puts on the pads and easier to remove pad

Correct.

The stock plate for the Mark II tools maintains all the lateral engagement strength of the previous generation, but reduces the sheer (peel) strength so the pads aren't so hard to remove as they were on the ES tool standard plates.
 
Backing plates from my MKI will NOT fit my MKII.

Can I purchase a 5" plate for my MKII LHR 21?

Yes. The current Rupes backing plates for sale are meant to fit the MkII. It will also fit the ES legacy tools since they now have the same mounting points as the MkII. It will also fit the old mounting style of the first batch of the ES legacy tools, like Todd@Rupes mentioned.
 
The only plates that do not fit ALL tools are those manufactured and included on tools prior to July 2014. Everything after that date will fit all tools, ES or Mark II, blue or gray ring.

The plates are available from Autogeek and most of our distributors in the US.
