    ZTu radiator

    I had posted about this before. I finished the engine in my ZTu and next step was to address the radiator. The local shop said he didn’t think he could successfully re-core it. I took T.R.K’s advice and found another shop. Warren Townsend in Mt. Clemens, Michigan recored my original Modine...

    Z radiator. Does anyone build them?

    I’m in need of a ZTu radiator. I figure anything used I find won’t be usable since they’re all getting older. The radiator shop told me with my current one, the tanks aren’t nice enough to even consider a re-core. Frustrating, but it happens with a restoration. Does anyone recommend someone...

    Another Z question

    I bought a used radiator for my tractor. Had the radiator pressure tested and it passed so I installed, using the hardware my service manual listed. The left side of the shroud lined up & bolted up fine. The right side (pictured here) has about 2” gap between the shroud and shell and the bolts...

    ZTU battery box

    Here’s a battery box I had built for my Ztu How does it look to y’all? I think it came out pretty close to an original. The mounts and instrument box are originals. I plan to get it painted prairie gold soon

    ZTU Battery Box

    I don't think I've posted here yet, but I'm in need of a battery box for a 1948 Ztu. Mine is in pretty sad shape. I've been thinking of taking mine and seeing if I can pay to have a replacement built just like it, but I don't want to quite give up on finding a nice original just yet. Any...

    Is draining water / antifreeze before winter the right move?

    On my 1951 VAC, I haven't cranked it since April and with me being knee deep in a Moline restoration, I know I sadly won't be likely to mess with the Case any this winter. The tractor is barn stored, but I wasn't sure I had my antifreeze/water mixture exactly at 50/50, so I just decided to drain...

    ZTU rod bearing plastigauge question

    Did plastigauge on my ‘48 Z Torqued to specs with the plastigauge kit from Napa, had an experienced guy help me. The crank has been turned previously to 0.020 under, so with the correct rod bearings from welter’s we tested at 5-thousandths. At 5thousandths wear, will it be fine, as a machine...

    ZTU torque specs on rods

    Does anyone know off hand or could be so kind to look up and verify for me torque specs on the ZTU's piston rod? I want to plastigauge my new rod bearings this weekend, but I can't find torque specs anywhere at all in the shop manual I bought. I was told 55-60 ibs Thank you!

    ZTU shifter issue

    The shifter on my Z won’t go into any gear. You can just move it back & forth with zero tension. I removed the transmission cover yesterday and took these pics. I am of the understanding that the roll pin (I tried to picture below) is likely the culprit. But what do I need to do now so the...

    ZTU rod bearings

    I finished rings, rebuilt cylinder blocks and valves on the ZTU, so I’m down to rod bearings. The crank journals checked at 2.605 and according to what I find in the manual standard is 2.625, so my crank has been turned to .020 under. Does anyone have know where to look for these rod bearings...

    Black & white picture of family Oliver in use

    I had posted this in another thread, but I thought maybe the Oliver members might enjoy this picture. This is my great uncle’s cotton gin in the South Carolina low country, in the early to mid 1950s. My grandmother was showing me the picture and off to the right I could see an Oliver (60 or 66?)...

    Gear oil question ZTU

    I'm replacing front wheels, radiator and radiator shell on my Z restoration, since I'm right there, I figured I'd check the gear oil in the front pedestal and replenish it. I see where someone had used grease in place of gear oil before. I'm guessing the gear oil was leaking (bad seals?) so they...

    ZAU value

    I really didn't ever plan on buying another Z and this isn't any set plan by any means, but anyway, a gentleman just right up the road from me who is a John Deere collector just pulled a Zau out of an estate and from my brief conversation with him yesterday, he'd be open to turning loose of the...

    Replacing Z jugs

    I bought replacement jugs for my ZTU, new rings for all 4 pistons, new rod bearings. I’m going to take it all to an engine shop and let him put the rings and bearings on, them put it all into the jugs. Dumb question, but I’ve never done this before, is it necessary to hone the bores on the...

    MM Z crankshaft question

    When I removed the old jugs/pistons for a ring job (will be putting replacement jugs on), I noticed on one of the journals a scratch. Doesn't appear deep and when I run my finger across it, it doesn't catch my finger nail.. So just from that, it appears not very deep. Is a small scratch anything...

    Crankshaft journal scratch

    When I was removing pistons, I believe I let one of the rods or caps come in contact with the crank journal, like a dummy. I notice a scratch now, but when I run my finger nail across it, it doesn't catch and I can't feel anything.. So I think it's very light and I will certainly be even more...

    Removing rod bolt tips

    I’m removing the rods from an MM Z. I wanted to get them out, as well as the jugs, to be sent off for a valve job, rings, hot tank cleaning I can’t get any of the bolts to budge even a hair, using a regular socket. What do you guys recommend? Has anyone done this on a Z? I was thinking...

    Vac case oil leak question

    I noticed today my VAC is collecting oil up by the front two spark plugs.. What’s this a sign of? I was thinking faulty valve cover gasket but didn’t know if it could be a sign of something worse? Oil pressure gauge reads good, tractor Didn’t run hot or anything and when I pulled the dip...

    1951 VAC revival

    I know she isn’t very pretty yet, but this post is a follow up to an earlier post I had written. Here’s my 1951 VAC that belonged to my grandfather. He raked & fluffed hay with it. I was born at the end of 1997, so it was circa early 2000s the last time I remember it in the hayfield. It had...
