    In your case, the book you might have been reading would be the service manual; I vaporized two days of my life replacing head gaskets, water pump, et al, in my ex GF’s ‘07. I have disliked Subarus ever since. They do go well in the snow, though. Sent from my iPad using Tapatalk

    The pinion seal replacement I set out to do morphed into this: Mission creep. Sent from my iPad using Tapatalk

    72 IH + ‘85 Alaskan = Questionable Judgment...

    Here’s my theory after 15 years: 1. Wide tires with high inflation pressures. 2. Low axle gearing. 3. No center diff. 4. Numb steering. A Subaru will run rings around this thing, and you could read a book while you were doing it.

    A week or so ago, I decided to take a closer look at the rear axle third member I bought from JJ back in October. I got it because it has a Detroit No-Spin LSD in it, which might have prevented the loss of traction that led to the Hagerman Incident. After taking a closer look, I found I had...

    72 IH + ‘85 Alaskan = Questionable Judgment...

    Thank you! ‘08, 240K miles, and it’s been a really reliable vehicle. IIRC, Alcoa wheels only came on first-year PW’s (‘05?). The later trucks came with look-alike wheels (like mine). I’m not big on 99% of the aftermarket wheels I see, because it seems like 100% of them have the wrong offset...

    After a long, snowy drive back to Wheatland and a good night’s sleep, the testing began: The 392’s compression numbers ranged from 90-120, the 90 psi figure being an outlier. Ok at this elevation, and likely usable. The 345 however shined: 135-140. Pretty close to new sea-level numbers. We...

    So I left the 345 to sit while I concentrated on my build-out, figuring that was that. I ordered a gasket set for a reseal, and a complete set of brass freeze plugs. That was that, until about three weeks ago when a buddy of mine on BP PM’d me a Facebook screenshot of a 392 for sale south of...

    I got lucky with mine: it was a bucket/utility truck owned by the GSA, then a fire truck after being surplused out. Used intermittently, and only in good weather in its second career. Very little rust in this one.

    That self-bailing comment got me: LMFAO here. I think IH sourced their body panels where Lancia did. They rust with the same boundless enthusiasm. Sent from my iPad using Tapatalk

    Sounds like the punch line from that old dog joke: “answers to the name of Lucky.”

    Scraping done to the limit of tolerance, it was time for a wash. The weather was cooperating, so first a pre-soak with rig soap: Then I rolled the engine outside and the pressure washer with it, where I promptly had to disassemble the carb because it hadn’t been stored correctly: Function...

    I got some advice on engine cleaning from the old hands on Binder Planet and grabbed some tools I thought I’d need: Started with a good vacuuming: Next, I tried to gunk & water proof it as best I could: I then grabbed my tools and got to scraping: And scraping, and...

    So the search for an IH SV392 began. I called Coonrod’s IH Parts in Grant, CO, pretty much the go-to for used IH parts: nothing. I called S&J Engines because I’d seen IH long blocks on their website a few years back: out of IH engines because a lack of rebuild parts availability. I posted...

    72 IH + ‘85 Alaskan = Questionable Judgment...

    Because then I’d have fabricate engine mounts, source an adaptor plate or different transmission, replace both axles because the lowest gearing for the rear is 4.30:1 IF you can find it, and conceivably add a transfer case to that list, if the transmission is not compatible with a divorced one...

    Next, Harry and I brainstormed this oil issue. I wanted to take a trip to Canyonlands, so I really wanted to get this solved. First, I changed out the 20W-50 for 10W-40 oil because IH heads have oil drainback issues and I thought that thicker oil was building up in the head & leaking from the...

    When I got back from Red Canyon, I replaced the flattened split-locks on the axle shaft bolts: and torqued them down to the specified 45 ft/lbs. Then I mended the shock mount that broke: This was a little more complicated than I’d thought initially, because I needed to make sure the...

    There’s zero public access in that part of the Laramie Range, unfortunately. Gotta go to the north 15 miles or so, and then it opens up a bit.
