    Default welding to hydraulic ram

    Hi all.

    Just found something new to occupy my time, my new to me, backhoe. Not the fastest thing around, but with a bit of commonsense I recon it will do the job.

    As one would expect for something of its age, theres some issues with her that will need addressing.

    Doesnt look like its seen a gease gun for quite some time. Regreasing and the usual dumping of fluids and filter changes is at the top of the list.

    Anyhow here's a couple of "quality repairs" that I will need to fix. Some of the welds havent rusted, so my assumption is ss rod has been used on some of the repairs.

    My thoughts are (but am definetely open to suggestions) is to remove any [hard chroming?] from weld area before rewelding any replacement bits.

    pic 1 is my first job
    Pic 3 isnt as bad, but dont want to wait too long before effecting any repairs.
    pic 2 and 4. Thinking seriously about removing bush and welding in a fresh one. Maybe tack replacement into position with everything in place? Whoever did these "repairs" didnt believe in grease points, so those will included as part of the fix.

    Anyone know if "yolk?" in pic 1 can be bought as an off the shelf weld on bit?

    Suggestions welcome.

    Thanks in advance,

    Jatt

    my bad pic 1 is actually no. 4

    For interests sake, here's a couple of fotos of the Yellow Peril.

    Havent been able to find much on the loader and hoe attachment, which appears to have been done by Cranval here in Aust.

    Like the idea of the plastic bits that are holding the teeth in place. Hoping they will be easier to replace than something that's weld on.

    Nice little machine, fairly sure my neighbour has one on a fordson major carrier.
    I have a feeling that the clevices were originally threaded onto the rods, (note the set screw and lock nut), however they probably worked loose over time and copped a weld. All I would do is grind out the old weld, extend the cylinder, give a bit of preheat and lay a nice hot weld with some low hydrogen sticks with a mig as a second choice. If a clevice is too far gone, then a new one could easily be made out of some heavy flat bar or plate.
    As you no doubt realise, the old girl doesn't warrant a full line boring job and as such, I reckon that your best way forward will be a combination of oversize pins, oversize bushes and lots of grease to produce a usable backhoe without too much play in the links.
    Cranvel was taken over by Connor Shea if I remember correctly.

    Probably worth noting that if the clevis is welded on then the cylinder will probably not be able to be disassembled to replace the seals in the gland. Could be worth putting new ones before hand?
    Depending on how much heat shunts up the rod, perhaps the wet rag trick to help prevent seal damage?
    (Disclaimer - I have never welded hydraulics before so this is a WAG on my part)

    I actually knew that, you were witnessed gloating to our American friends on another forum

    I would expect that any threads will now be somewhat useless now, hence the welding. New seals may not be a bad idea, but if your cylinders are holding oil, I would be inclined to leave well enough alone as it is very easy to open Pandora's box and spend quite a few dollars and time on resealing. There will be a piston on the opposite end of the rod that will probably be threaded on anyway. These machines were built "the right way", as in threaded components, mechanical joints and traditional workmanship. Other than lack of greasing leading to premature wear, the old girl looks in reasonable condition and should be a reasonably cheap machine to operate. Does the hour meter still work? If so, how many hours has she got on her?

    Yeah I have posted the old girl up on few forums. I know stuff all about this tractor, so hopefully a bit of "show and tell" will help me out. Already have found out a few facts about her I didnt know.

    Then there's the saying, "no fotos and it didnt happen!!" And we all like fotos.

    Hours: Havent looked to see if its even connected, too busy playing sandpits Should pay more attention to see if the numbers scroll , but has probably gone around the clock anyhow.

    Certainally has done its fair share of work. Clutch doesnt seem to have much play left. middle (2nd) gear wont stay in gear.

    Starts without fuss. Expected a few niggles that come with old equipment.

    Hydraulics as expected are a bit slow, but everything seems to work in this dept.

    In all a low tech unit, just the way I like em.

    They seem to be a well respected unit, (the 154 tractor), albeit one that was introduced at a strange time. It seems that Leyland had the opposite issue with the 154 to the one faced by the infamous P76 car. One was a small tractor being marketed when everyone else was going big and the other was a big car, released when thew rest of the market was downsizing. Having said that, they had a fairly long model run and today are recognised in their home country as a smart choice for small holdings.
    Parts may be a little difficult to come by as neither Bareco, Sparex or Bepco seem to list your model, but there may be other aftermarket suppliers that cater for your 154. A lot of lighting, electrical and even mechanical parts will be pretty generic anyway.
    Low tech is good from a maintenance/repair perspective.

    The Leyland Tractor (UK) forum is looking promising in the parts dept. Of course one doesn't want to get stuff from that far abroad unless really need to .

    From casual glance elec all looks to be the infamous Lucas. Diesel mech that visited here (we get all kinds of folk here at the shop) on other matters seemed to think I should be ok with many repair items.

    Ah yes Lucas, Lord of Darkness. Having grown up on Land Rovers and Fergusons, he has touched me on several occasions. Having said that, once he was all we had.
    A Bosch alternator will fit nicely in place of the Lucas alternator, (surely they don't still run a Lucas generator do they?), if required and the starters seem to be pretty trouble free. Switch gear can probably be substituted with either Massey Ferguson or later model Leyland parts. That's the beauty of the old girls, you can mix and match, plus not a great deal changed between makes and models. What you can't buy, you can make.

    Seems like you might have been readin straight from my bio. Played a little bit with grey MF20 and Army Landrover over over time. Yes have done the toss the Lucas and insert one Bosch.

    Helpful folks from Leyland Forum UK seem to think mine is about a 78 vintage. So one would think alternator. I know she starts easily, once you give it about 20 odd sec on the glows.

    So far so good.

    Does yours have actual glow plugs or the CAV manifold heater as fitted to Perkins engines among others. The one with a diesel line from either tank or fuel pump and a power supply that heats a coil until a check valve opens, allowing diesel to flow and thus ignite?

    Looks to me like glow plugs.

    Yep, definitely glow plugs.
