To return to the subject at hand. Repeated applications of home-made penetrating oil in all orifices, gas torch until sizzling then cooling, spindle in soft jaws, spanner on petrol cock body, turning…. “Click!”. The threads in the body need cleaning up, they’re stiff, the spindle threads seem to have suffered. Don’t know what the thread is, might be 1/16″ BSP (?). I’ve got some gauges somewhere, and some taps.

Hi, it’a a bog standard petrol tap as in the example pictured from JAPG Mowers. The turning buttom has fallen off (not a problem, I can make one). The hollow nut around the spindle unscrews, there’s a rubber “O” ring under, nothing else to be seen. The die cast body is in one piece. The spindle will not turn. It is stuck open.

Looking at the machine, the left handle might come off fairly easily. However, for trnsport, I turned the whole thing onto its side, and left both handles sticking out of the right hand back door of my van (yes, the floor became slightly lubricated with oil from the machine).

[rjy]

Thank you, that is interesting. I assume it’s a later example if it has that engine.

I’ll be able to have a closer look when I pick it up, assuming I can get it in my little van.

I had thought of making a new lining, but the material is another issue. It would have to be something that is not going to wear the steel outer cone, and is pliable enough to bend. Don’t know what was originally used.

[rjy]

£100 to £150….

[rjy]

OK, I put it all back together, and it does not seem to be slipping. I see that relined cone clutches are £200 to £150ish!

[rjy]

The light dawns (I think). The pitted piece is the corroded end of end of a long inner race for the bearing (INA NK37/30 Needle Roller Bearing). Unfortunately I’ve just put it all back together so can’t measure it. If anyone knows, a note here would be excellent 🙂

[rjy]

Might be a horse-drawn harrow, that someone’s attached to something rather more powerful, with consequences as seen?

[rjy]

Coo! Who’d a’ thunk it! Thanks for the info!

[rjy]

OK, it’s got the two-seal setup.

A 27mm socket made an ideal “special tool” to use for pressing.

The inner seemed to have been installed rather clumsily (from new I guess) being rather distorted, the metal insert being dented on its face; the outer was considerably worn, the inside diameter being 0.063 larger than the inner seal’s inner diameter!

The rotor drive sprocket shaft surfaces are not in good condition, as pictured.

I have ordered two replacement seals for each side, one R21, one R23 (one with, and one without without auxiliary dust seal), although I can’t really see the point, bearing in mind the state of the metal surface, the outer will likely wear rapidly.

Gasket paper ordered too. I suspect 0.8mm Flexoid is OK (I have ordered some 0.5mm too just in case).

A good thing I checked – they’re 1 34/4″. The same question I guess still stands, about whether or not to get two oil seals per side, plus another question: What size are the imperial ones?

Wmtbearings have an imperial seal, saying: “This seal is 1.3/4 = 44.45mm”, but don’t say whether it’s one per side or two, or whether single lip or double. I’m wondering about that because the seal’s garter faces outwards on my machine, which is (to me) unexpected. An eBay seller has some £.robbery_with_violence and I can find online some 175 118 18 TC (1 3/4″ x 1 3/16″ x 3/16″) at £.reasonable.

I suppose the best thing to do is press the seals/bearing out and have a shufti.

[rjy]

I agree. I have to say I feel a bit gloomy about it, but it might be possible to get it usable in some way. These seem rare, although they do not seem to sell for much. I had another look. The coffin-shaped box has largely disintegrated, and a few rusty tools and semi-oily chains and sprockets and things can be seen under it. There’s a (rusty!) tobacco tin in the works which seems to have a little dried up grease or something in it. Spare parts don’t seem to be particularlty common. The tin (sheet metal cowling) where I assume a starting handle goes has no middle, by the look.

I’ve got a amongst other things welder, a couple of gas torches, a press, some old tools, a big bucket of HCl and a sledge-hammer. Oh arr um.

Maybe if I can dig, literally, and drag this one out something else will turn up.

Hi Charlie, I’m OK with the functionality limitation, not griping 🙂

The “legality of driving/pushing pedestrian controlled machines along the pavement” article I thought probably ought to go in the “Pedestrian operated machines” subforum for general interest, as I guess people occasionally do this. I’d spent quite a bit of time looking at parts of the Road Traffic Regulation Act 1984, “Learning to drive a tractor or specialist vehicle” (- HMG), and the Road Vehicles (Construction and Use) Regulations 1986, and included them for information/discussion. I can’t find a “yes/no” answer anywhere (but non-ride-on mow grass mowers seem to be OK). When I pressed “Post” I seem to remember a “Your post is awaiting moderation” type message. If it’s not available, i should be able to reconstruct it fairly soon by looking at my browser’s history.
