    4219T Disassembled Engine available

    BTW, the best source for used parts during my repower adventure was Wengers in PA - great online selection and prices - and willing to dig thru local inventory to find what I needed

    4219T Disassembled Engine available

    From a 1985 JD 410B Turbo backhoe. 4219 engine is complete (jncl injection pump) except for the turbo, flywheel, and crank pulley that I used on the replacement, a 4045T engine. Posted here on the classifieds. Head recently rebuilt less than 1 hour before bearings failed due to oil...

    Advice on replacing 4219T with 4045T in 410B Backhoe

    R92436 was the ticket - perfect fit - success!

    Measuements for thermostat housing R64268?

    scott 730 is right, my request was way too specific to generate many responses. For the record, if anyone is trying to repower an older 410/510/610/710 series backhoe with the 300 series engine, the newer 4045 block and head use a different T stat housing than the legacy engine. I had fit a...

    Measuements for thermostat housing R64268?

    A kind seller measured their R64268 housing, and it appears to be too small for my repower project. That leaves the R92436 to measure - I need approximately 6 in and 7.125in from the mounting flange bolt holes to the closest radius of the water pump bypass tube to fit.... Still haven't found a...

    Measuements for thermostat housing R64268?

    Does anyone have an R64268 or R92436 thermostat housing lying around that they could measure for me? Specifically interested in the distance between either of the two bolt holes at the cyl head flange to the bypass tube. Thank you! This post was edited by sovste22 on 04/08/2023 at 08:48 pm.

    Advice on replacing 4219T with 4045T in 410B Backhoe

    Need some advice on locating the correct thermostat housing for this project. A few months ago this forum helped me plan to replace my wasted 4219T with a 4276/4045T. The 4276 is now in the backhoe frame, and I've adapted most of the legacy 4219 hardware to the 4276. My last hurdles are the...

    Which 300 series engines can replace the 4219T?

    So my 4045T arrived pretty much intact, and I was surprised to find two stickers on the valve cover indicating the motor is a JD-authorized RPO JD reman. Apparently RPO services timber industry equipment in SoCal and AZ, where this engine came from, reportedly from a HydroAx feller buncher...

    Which 300 series engines can replace the 4219T?

    Wow - that is right on! All four sleeves had a broken upper o-ring and cavitation erosion on the exterior of the sleeves, progressing in a v shape upward from each o-ring break. Yes, I never added corrosion inhibitor in the 15 years that I've owned it. But I don't fully understand how the...

    Which 300 series engines can replace the 4219T?

    Thanks for the welcome! I've been a lurker over the 15 years I've owned this 410B - great forum with great people. Glad to hear the form/fit should be OK with the 4276, or 4239 if I can find one. Other than needing to change the muffler, I suppose I could even toss a non-turbo engine in there...

    Which 300 series engines can replace the 4219T?

    Thanks, Jim - this confirms what I found during my searches, but I didn't realize the Hydro Ax 221 might have the 4276T....that old model and related info have been extremely hard to find using my search engines. I had been hoping this was a 4239T simply due to it being closer to my 4219's...
