Title: Late series bumper rubbers repair
Post by: Nigel on June 23, 2024, 01:16:28 PM
A part of the repairs after the accident was to refurb the new-to-me bumpers,
specifically the rear, where one of the rubbers was hanging off.

I'm sure there are other ways, this is how I'm doing it.
The original steel inserts corrode and break/fall out. I removed all the old
bits and what's left is a circular slot with a flange within. I got some
stainless bolts and washers, mig'd them together, and with a little effort,
they push into the slot. Most of them are tight, and although would probably
work as is, I'll put some SikaFlex on top to make sure.

The other issue is that this centre section has shrunk in length by about 25mm.
This may be a challenge, not sure how to pull this yet.

Where the two rubbers meet at each side, there are
two bolts at the end position of the curved piece.
This meant something slightly more complex.

The principle is the same, there's a slot around the base of the hole.

Hi Nigel,
I recently stripped, cleaned, polished and rebuilt the bumpers on my HPE and encountered the same problems.
You seem to have it all sorted except the shrunken middle section. Mine was exactly the same.
My basic instinct was to warm the rubber in the bath (whilst the missus was at work) filled with warm/hot water and quickly fit the furthest bolts then working inwards. It worked but I didn’t have long to wrestle it in place before it started to shrink. But it did go on nicely in the end without pulling the rubber fixings out or any signs of rubber distortion.


Cheers
Ian

Hi Ian,
Thanks, that's a great idea, I'll try that next weekend when the sealant has cured.

Cheers,
Nigel

I would second Ian’s idea. I found hot water softens these rubbers significantly on various parts.

Ian's plan worked.
All 3 rubbers are now installed.
