BIG thanks to Mark (Snoopy) for coming over and spending most of the day helping to put the back end back together. Displacer got re-hosed. Here I am "adopting the position" for final tightening.  And here's Mark tightening it up even more..  Latest update to this process sees the addition of a copper crush washer in addition to the PTFE tape.   Alloy carrier facing surface slathered with copper slip.   And bolted home. Interesting psychadelic flash effect.  There it is. Note nice new big polyurethane bump stops. We got the housing home eventually. There was a degree of improvisation at the back end, finishing with the fitment of through bolts through the carrier. All good and solid in the end.  Coupling up the handbrake cables. There was bounteous bad language......  And Mark complaining that "his" engine bay was dusty. I suspect that he hasn't been paying attention for the last couple of weeks.  Anyway, bled off the rear brake, re-set the hand brake, dropped her back down on her wheels and blew her up. As part of trying to chase air out of the displacers, we gave a jolly good, vigorous bouncing. This revealed a horrible metallic "clack" from the rear suspension on the other side. Still not going anywhere then.  Even so, it's been a fun day, if damned hard work. Chris.

It looks like you and Snoopy are engaged in some form of weird ritual. David |

Heh. I can get the hose VT. Mark can get it FT.... He also spent the day complaining that I kept putting all the tools back in the right drawers, so that he couldn't find anything. Anyway - hunt the clack. Dropped off the suspension housing on the off side. Mick wandered in claiming that he was bored. Mistake - got the hydro hose undone though.  A quick poke around showed that the displacer was not sitting straight in the housing. The rubber support ring and it's flange were very distorted and pushing the displace to one side.  You can see the mark. Was that it? Or - was it the wobbly bearing in the radius arm? There was a big rust mark and some quite noticable play.  That'll be this then. The cage positionong the rollers has broken up. A delicate attempt at knocking the centre tube out with a large copper mallet failed, so I nipped over to Mick's garage to annoy him. He's also got a ten tonne press.  That got it apart. It took 6½ tonnes before it came free. I have no idea what the red stuff is, but I'm quite certain it shouldn't have been there.  The outer races showed clear signs of brinelling. These are the little grooves worn through the hardening by a bearing which spends most of its life in one place or moving through a small arc. The WM describes removing the outer races using Service Tools 18G 284, 284D, 284H and 284J. An extensive search of the garage revealed that I had none of these, so used the die grinder to cut through each race at two points, thus allowing them to fall out. Cleaned everything up and fitted new bearings, centre tubes and end spacers.  That's ready to go back on. Cleaned up the suspension carrier and the displacer body. They've been rust treated and will get painted over the next day or so. It also requires a new bump stop in the top housing as it has disintegrated. So that's three possible causes of the metallic clack. As to which one it'll actually prove to be, I've no idea!  Chris. |

Are you going to fit a grease nipple? David The outer races showed clear signs of brinelling.

Don't think it would work. They would have to go at the outboard ends, and those seals on the bearing ends are pretty flexible. I suspect that the grease would just ooze out. Anyway, the first ones lasted 49½ years. By the time that passes again, I'll be long gone!

I've seen an article somewhere of the grease nipple conversion, maybe in the old LOCA magazines. I recall our Mini back in 1964 either had them from new or I think were prbably retrofitted as the bearings used to be a common failure. Point taken about not worrying too much about replacing them again in 50 yeaars! D Don't think it would work.

There we go. Everything cleaned up, de-rusted and painted.  Pleased with that. New nylon cup and rubber boot for the end of the push rod seeing as we're in there.  And re-assembled. That is a d@mned heavy lump of metal. That's it until the bump stop turns up, then I can see about finding a mug some help to get it back on the car. Chris. |

While its apart is worth changing the hose as preventative maintenance and save pulling it apart again in the future

All right, all right, I'll do it. It's not like I've got anything better to do with my time. Like paint the d@mn thing.
