    Oil & Fuel YM2500 Pushing Coolant Out the Radiator

    I think that what would be fair would be this: 1 Take the tractor back to Fredericks 2 Full refund for the original cost from Fredericks to you 3 Full refund of your mechanics costs to you 4 Payment to you for time & fuel for this last trip 7hrs each way. I don't think it reasonable out of...

    Oil & Fuel YM2500 Pushing Coolant Out the Radiator

    Yeah - tractor idling for goodness knows how long, then throttle blipped & a puff of black smoke is pretty normal I'd say. Try that with the average Lister & you'd be coughing for a week!

    Ym276d not starting

    Try a jumper wire from the + battery terminal to the solenoid terminal on the starter. If the starter spins reliably, then the solenoid is OK, if not replace. Also, if the tractor lives in the weather or in an open shed then it's possible that the main battery/starter cables have corroded...

    Hydraulic pipes

    Thanks, I hadn't noticed! I reversed the wheels to give more track & must have mixed them up.:unsure: I'll swap 'em over today after I've finished bashing rushes with my Zetor & flail. I've just done the same on a Wheelhorse rear agrityre<DOH> I had such a wrestle to break the bead (hasn't...

    Hydraulic pipes

    Everybody loves workshop pics so here are a couple of mine. When I built it 40 odd years ago I never dreamt I'd need to get a 10ft tall tractor or modern pickup inside, so it's a nuisance that I can't. I bet if I'd built it to take a 10ft tractor I'd probably now have a 12ft one anyway:D. Thats...

    Hydraulic pipes

    No idea of the flow /pressure - the ram is one of the bucket curl rams from a loader & I currently use it on the hydraulics of a Cushman Turf Truckster which has a 3 cyl Kubota engine & a hydraulic pump driven by a single A belt! It works fine for speed on the Cushman, power not so impressive...

    Hydraulic pipes

    Just completed connections (see below) - all works fine:) with one proviso: I had 4 new 1/4 BSP QD connectors in the workshop- can't remember where I got them from - probably in a box of stuff from a local auction... Anyway,when I connected a test cylinder to these, on using the spool I could...

    TM1820 Starter circuit

    Ah! I thought the cable connectors looked "factory" to me & I've now found that , although not shown on the wiring diagram, there IS a "fusible link" factory fitted in there. https://www.tractorpartsasap.com/fusible-link-new-yanmar-194550-51220-181057.html?Screen=PROD&Product_code=WH-455...

    Hydraulic pipes

    Just found that the plug on the left side of the gearbox is actually 3/8BSP! Checked the output & return on the hydraulic distributor & they are both 3/8BSP too! That'll make connections much easier since I have lots of 3/8BSP fittings in my collection. I hope the internal plug fitting is...

    Hydraulic pipes

    Right, I've fixed a double spool valve I had surplus behind the seat of my 1820, read up all about the need to insert a plug in the Yanmar hydraulic distributor & the need for a power-beyond sleeve in the spool valve, so I'm all set to plumb her up. What size hydraulic pipes do others use? My...

    YM 1820 Mystery electrical box

    Yes - it's a timer for the Thermostart circuit. When you switch on the TS, this box lights a small red lamp below the ignition switch. Hold key in TS position & this light goes out after about 20 seconds. Not needed functionally: it just supplies the warning light as far as I can see, the...

    TM1820 Starter circuit

    Clean wire from teminal C on the ignition switch direct to the S terminal on the solenoid. Turn key: fuse blows. Found a 40AMP slow blow MAXI fuse & connected that in place of the fuse. Turn key: fuse blows I dug out an old ammeter from a box in the garage where it has sat for about 40 years...

    TM1820 Starter circuit

    I'm thinking that the pull-in coil in the solenoid is drawing too much current & blowing the extra fuse before the reduced hold-in current is applied. What troubles me is WHY they put in the fuse in the first place. Solenoid & starter work perfectly with jury rigged wires, just not with the...

    TM1820 Starter circuit

    Yeah - I agree with all that. I'll try a new wire from terminal C to the solenoid & see if the fuse blows. Just to avoid misunderstanding, I attach the following sketches showing (Start1) what should be in place & (Start2) what was in place when bought. I'll be quite happy to ditch the...

    TM1820 Starter circuit

    But it's in the ignition feed, not the actual heavy starter circuit. i.e the wire that feeds the ignition switch & subsequently all accessory circuits. It has to handle supplying the solenoid switch current (about 10A apparently)until the engine starts & supplying accessory current thereafter...
