    Rear axle build (big ford in Cat-426 1st series) 01 ring-gear remove

    Huston, I have a problem. I absolutely HAVE to find 16 rear wheel studs that are otherwise IDENTICAL to the stock ones but are 3/4"-1" longer. No one seems to make such, is that possible in 2026?

    another bosch p7100 problem: 12-valve won't keep running

    ISSUE RESOLVED. 3 overnight soaks in 2-cycle oil; I had also opened up the gov. housing and was lucky to be able to put it back together but it could have cost me a rebuild! Gum and varnish are still in there so I'll use Lucas diesel-treatment in purge mode for a while and then in just...

    another bosch p7100 problem: 12-valve won't keep running

    I had read in some idiot's readme file that half/half 2-cycle oil and acetone was the solution to use. No sooner had I flooded the plungers above the seals I found out that this was utter bull, so I immediately emptied them and immersed the entire pump in gasoline for about 3 hours. THEN I...

    another bosch p7100 problem: 12-valve won't keep running

    That's why they advise to priorotize beginning with the simplest possible solutions. My problem is lack of familiarity, in this case for example I had never built a diesel until I was 65 or so, or saw an injection pump for that matter, or a rear axle the first and last one which had been my...

    another bosch p7100 problem: 12-valve won't keep running

    I must be losing my freakin' marbles because I could SWEAR I had pushed a metalic ruler-like bar forward by just touching it. Anyway, I don't see any such thing in there at all. In the video, as I rotate the power lever forward the linkage seems to just momentarily load a spring which would then...

    another bosch p7100 problem: 12-valve won't keep running

    38 minutes later I can no longer edit. What I thought was the rack sliding forward may have been something else. I have the back end cover screws removed (one was missing), looking for a way to remove tat cover to see better.

    another bosch p7100 problem: 12-valve won't keep running

    Got some more: I pulled what could be called the boost compensator bump atop the rear (power lever) end to be able to look inside. As soon as I touched the rack it slid all the way forward so it's extremely free (looks like it was disconnected from the power lever linkage). But the shutoff lever...

    another bosch p7100 problem: 12-valve won't keep running

    The last otherwise good run ended with a bit of overheat to about 230-240F, engine ran good and shut down normally. On the next start it fired but would not keep going past a few seconds. This same behavior repeated on each of maybe half a dozen subsequent attempts. Doubt very much if OH has...

    Rear axle build (big ford in Cat-426 1st series) 03 outer-bearing & seal

    I finally got the parts but am no further ahead. Rear axle sealing NOT being a procedure to take lightly... What is called the 'retainer' looks like a seal AND a retainer #9R2410 has a black rubberish seal with a spring around the innermost ring: straight forward, everyone has seen...

    Good used parts sources?

    Checked them out already, they found a used axle but far stateside so with exchange and transport it was way too rich. Anyway, I've decided to rebuild, do a proper job and be done with it. It'll cost me about $3k in parts plus some work by my blacksmith to make a couple of 1" spacers between...

    Deutz-Dx-605 cylinder head temperature gauge calibration

    As expected the rear cylinders are a bit warmer at low loads. I want to use an IR pointer to read cyl temperatures for and idea of calibration. Any one have any practical experience about how IR readings on the exterior of air-cooled jugs relate to actual temps on the inside? What's the best...

    Rear axle build (big ford in Cat-426 1st series) 01 ring-gear remove

    I rigged myself a DIY puller with 3/4" threadrod and that ended up as a day wasted, using long nuts I pulled the rod apart eventhough the lowest shown tensile limit is around 20k lbs. Gonna take it to my blacksmith for the ring-gear extraction/press-in. Don't know how I would've done it if left...

    Good used parts sources?

    THANKS, I'm in contact with them for some new parts, they appear reasonable, looks like I'll be buying from them to find out their real-life value. It's always that 1st transaction that's risky :-)

    Good used parts sources?

    I have my own (hosted) web server but don't store stuff on it or in clouds for lack of sufficient need (so I thought anyway!) Don't understand what you mean by "but I will try". I only mentioned the data-loss in response to your story about a will. In my case the loss was about 200gb of...

    Rear axle build (big ford in Cat-426 1st series) 03 outer-bearing & seal

    The LEFT axle (having lost some oil) was removed by a shop and that was when I took over! This left axle had a chewed up outer bearing, damaged race, and no seal found (probably discarded by the shop). I pulled the RIGHT axle and on it I found - the cone bearing in good shape - cast in-place...

    Good used parts sources?

    I don't remember if I had mentioned it but the data-loss event hit me in the middle of rebuilding my computer when i got the unpleasant surprise of having to find the will of my younger son in his two computers, all with multiple operating-systems and much of it encrypted. That was in January...

    Cat-426 (not 426C) first series #7BC01181 Parts Manual

    Similar standards, used to be far better, and it's all metric now. And after almost half a century on metrics most hardware stores still don't have a single metric nut or bolt! We'll give Cuba 11th province status (currently 10 provinces + 3 territories), then see what he thinks of THAT. As...

    Rear axle build (big ford in Cat-426 1st series) 02 axle preload measurement

    The good book says to use a shim under the preaload bearing equal to the feeler-gauge fit. It looks like telescoping part 2 of the tool might be the thickness of the bearing and that the 3 legs of part one rest on the edge 3 so as to measure the shim that might be needed to raise the bearing...

    Fortunately the prtoject was almost done and the most valuable image (my own wiring diagram) survived on a USB drive. I also managed to recover some stuff from the net.
