    12 or 24 volt system on Lull 644

    Might not be easy to see, but most alternators have specs stamped on them, generally on the frame just below the bolt ear for the top flange, that will say 12 or 24V. Starters sometimes also have tags on them to note voltage, then there's the gauges in the dash. Also the various solenoid coils...

    12 or 24 volt system on Lull 644

    I checked the specs on 644 HIghlander, the 644B, the 644C, and the 644E and they're all 12V. I've never seen a Lull that's 24V from the factory

    12 or 24 volt system on Lull 644

    Anything is possible but I've never seen a 24V Lull 644 myself

    Bobcat 773 starter replacement

    Not just through 70's and breaker points, my '85 300 Six, vacuum electronic distributor, coil, Duraspark ignition controller. When you crank it the R terminal sends a voltage signal to a wire on the Duraspark to advance the timing to assist starting. Once you release the start position, advance...

    Any Detroit Diesel experts here?

    Yeah, I was going on memory, which I admit is very vague since it's been years since I've worked on these engines. Thanks for the correction. But I will say, and my memory is firm on this, I've never been a fan of the 53 series. When running they have no sound, no tone, nothing but noise...

    Bobcat 773 starter replacement

    True, and that R terminal is typically used to control something, like trip a relay or send a signal to an ECU when the solenoid is engaged, but the solenoid is still self grounding.

    Bobcat 773 starter replacement

    On the F series with the Delco starter they didn't use an R terminal on the starter, only the S terminal, the solenoid was self grounding.

    Bobcat 773 starter replacement

    Ohh Kay, that's plenty sufficient voltage to light up a starter solenoid. What kinda shape is the ground cable between battery and starter? The ground cable connects to that bottom starter mount bolt. For $hits and giggles, get a set of jumper cables, use only the black ground cable, connect...

    Any Detroit Diesel experts here?

    I could be wrong as it's been years since I've worked on these, but I think the 53 series had dry liners unlike the 71 series that had liner o-rings between the coolant jacket and the internals.

    Bobcat 773G

    Ok, I'm baffled, this is technically not even possible on a 773G series

    Bobcat 773 starter replacement

    You need a helper. Connect a volt meter to the terminal that has the white/green wire (start signal wire). Have your helper hit start on key switch in cab while you check how much voltage is on that white/green wire. You should see a good nominal 12V. If you're seeing anything less than 9 to 10...

    1974 Versalift boom truck

    Well, let's take a stab at it. Yes, Versalift guy is likely correct, most manufacturers now days don't support product that goes back X number of years, there's not enough of those models still out there for them to support parts on their shelf that never move, obsolete. Second, if i's leaking...

    Bobcat 753 - Pulled engine, fixing leaks and fan drive.

    Doesn't have to be fully confident thread material there, Loktite fills gaps and makes a bond to the metal. We have two very old Gehl DL-10 telehandler forklifts. Don't get me started how much I hate those machines, but here we are. One of the things I dislike about them is the steering tie...

    Owatonna (mustang) 330 24hp motor swap with 20 B&S vanguard motor.

    Well, 4 less HP is still better than a boat anchor. Whaddya got to lose?

    Bobcat 753 - Pulled engine, fixing leaks and fan drive.

    Tough spot for a heli coil. Remember, gotta have room for the tool to install the heli coil as well. Another option, worth a try, and if it doesn't work you can always go back to the heli coil. Use a metric stud, set the stud in the thermo housing using red loktite, give it plenty of time to...

    What happened to the optional over-center boom backhoes?

    That's a good question, and I have no answer. The over center latching booms also tucked the backhoe closer to the parent machine, making less tail dimension. And, unless I recall incorrectly, since they tuck up tighter you could swing the backhoe fully left of right and it would still be inside...

    Bobcat 753 - Pulled engine, fixing leaks and fan drive.

    OMG, I used to drive an '86 F350 with a 6.9 cornbinder engine when I worked for a drilling company. Gutless, but like the 300 will run forever! I imagine with a turbo and 5 sp it's a totally different engine, never experienced that pleasure.

    Bobcat 753 - Pulled engine, fixing leaks and fan drive.

    I feel your pain, but I roll older than that. My daily driver is an '85 F150 with a 300 Six. I've neutered what little computer control it had with OBD1, no MAP sensor, no EGR, no TPS, computer controlled dizzy has been swapped to Duraspark ignition, plain Jane Carter YFA 1bbl carb. Pretty much...
