Depending on cost - I'd be thinking of a new clutch?
Otherwise can it be mounted to a drill/something it can rotate on etc so you can use a small needle file and gently file the grooves straight & tidy again?

It's outside the limits of dollar-amount right now.
There's 8 ridges that contact the outer drum. It didn't have any trouble engaging, I'm just wondering about all the shavings- they are alloy so wouldn't be picked up adding a magnet to the oil pan.
I know it's normal wear but those are really light and feathered and I don't care for the way they look, like it wouldn't take much for them to just strip off. I've had enough issues with metal debris in this gearbox, it doesn't need additional trouble.

would a stiff (ish) wire brush remove the alloy "snots" without disturbing the surface material too much?

No, they are too well attached for that, plus this is really soft aluminum (or aluminum alloy).

I know budget is a consideration but you only want to build it once - is it worth the risk to use a damaged part?

It's not damaged, per se, more worn. The steel drum it clamps to is in tip top shape.

Also the offset planet gear at a strange degree is apparently by design  Phil |

Maybe have a chat with your gearbox parts suppliers/rebuilders? see what they recommend re dressing it or replacing it?

I'm sure they'll recommend replacement, however I can ask. They've been very helpful so far.

 This is what a good clutch looks like. He says mine isn't great but it's not bad. Said it should clean up with a little care. Phil |

Took a looksee, the alloy has been overheated in places by getting steel swarf stuck in it. Luckily it doesn't slip the clutch unless the vehicle is moving when reverse is engaged.
I should be able to pick the steel out, dress it carefully and have it be okay.
I do need to build a contraption to compress the clutch springs, the official special tool has six pegs that press down on the ring, with two plastic coated hooks that grab the outside of the case and can tighten the whole lot down.
I'm going more simple. Piece of plywood, there's two bolt holes that are near as damnit central to the line of the bore, so two 3/8" 5" long bolts to hold it through that and 4 2" bolts arranged to press the ring down.
That should work well enough, redo the seal, pull the old bearing and put the new one in.
Should be ordering the parts tomorrow.

Added the one last plain bearing that wasn't on the list, because I've had to replace every other one...
Parts on order, should ship today.
Anticipation!

Just curious, how expensive are parts for this box?
Just wondered if this is within the normal realms of fixing cars or if its an expensive exercise that is unfortunately necessary.
Same sort of costs as rebuilding a motor? Or rare, hard to get parts and therefore super painful?

Seal and gasket set (gifted, kindly by Hairnet of the Beige) $148
Epicyclic drum front $82 (used but good)
Epicyclic drum rear $85 (used but good)
Fluid delivery sleeve $95
Front drum front bearing $13.90
Front drum rear bearing $13.07
Rear drum bearing $3 (x2)
Fluid delivery sleeve oil ring $3.42 (4x)
Clutch overhaul set $168.00
Rear drum outer return spring $3.45 (6x)
Main shaft thrust washer $9.00
Rear drum thrust washer $13.00 (2x)
Oil pump screws and servo spring $25.10
Rear planetary set bearing $13.25
Reverse gear sun gear bearing $22.90
Main shaft pilot bush $6.40
All in with postage $608
If only a few bits were worn out it would have been less.
To be honest it's no worse than overhauling a modern automatic gearbox in terms of parts cost. I decided to redo every plain bearing in it because I have it apart and it's really false economy not to.

 I built a contraption because I lack Special Tool whatever-the-number-is. Clutch compression tool.  The manual says to gently used compressed air to free the piston. My little compressor didn't have enough puff.  All it did was blow bubbles  A bigger borrowed compressor did the trick. That's gotta be the first piece not full of swarf, too. The seals are actually quite soft and pliable which was a surprise compared to the others. Phil |

 Dug grandfather in law's old small cold chisel out of the toolbox. Not in great shape.  Dressed the end, sharpened it (a little shallow but that's the angle it had on it) and now in good shape to assist with bearing removal. Phil |

 It was annoying me so I put a better angle on it. Phil |

As classic car prices are going up and certain models become more popular the prices of parts are increasing too. To be expected i guess but just because a car is now a bit more popular i don't really see why a balljoint has gone up from £20 each to £180 a pair! Thats what made me wonder about yours, cant be a huge supply of your gearbox parts out there and suppliers do have a habit of charging whatever they can as they know we have no choice! |
