Beer Posted March 9, 2021 Report Share Posted March 9, 2021 Would you have some schematics of the oil, water and fuel circuit of the A57 to see how many of each pumps are involved and how is the distribution and collection done? Quote Link to comment Share on other sites More sharing options...

Some. I have parts break downs for all the oil and fuel lines, and flow charts for fuel and I think water. It also depends on the engine. They are surprisingly inconsistent with what's in the various manuals. Quote Link to comment Share on other sites More sharing options...

I'm just curious to see for example if there are five oil circuits or one common for all engines. Quote Link to comment Share on other sites More sharing options...

I'm just curious to see for example if there are five oil circuits or one common for all engines. On the A57 from the start it used a dry sump system, with a big main suction pump and a secondary scavenger pump, and a big ass tank of oil mounted on the inside of the fighting compartment on the rear wall. Gas is sucked through one big mechanical pump for all motors. The cooling system was only only one that used pumps mounted on each engine bank, but the belt loads cause poor service life, so they switched to one MASSIVE water pump.

I'll clean up a couple of oil pump pictures too, I've been meaning too, the engine is really clever. Beer 1 Quote Link to comment Share on other sites More sharing options...

I assume the gear system that connects each bank to the main shaft could help, but I’m not 100% sure. Quote Link to comment Share on other sites More sharing options...

There is a giant firing order chart in one of the manuals, and I think you set the timing on each motor the traditional way, by twisting the distributer. I need to read through that section again.

Lord_James Posted April 16, 2021 Report Share Posted April 16, 2021 What is an M4A1E9? I came across it while bored, but the only information I saw is that it is “an M4A1 with spaced out VVSS suspension and extended end connectors”, but all the pictures that come up look like normal VVSS to me: Quote Link to comment Share on other sites More sharing options...

Oh, ok, the running gear was pushed out from the hull to accommodate the wider tracks. Quote Link to comment Share on other sites More sharing options...

I think it has to do with the drive sprockets meshing with the end connectors, which are also the guide teeth. You'd need an all new incompatible concept of track link design to fill both those functions while also being wider. Such a concept is the track with central guide teeth used on the HVSS Shermans.

That's awesome, I didn't even realize until you said something. 8 hours ago, ZloyKrolik said: They did. Pretty much every track extender had problems with them breaking/bending. Unbalanced loads are hard on tracks: e.g., the weight imposed by the Tiger Ausf.B's overlapping Staffellaufwerk was biased to the inboard portion of the tracks, resulting in track pins bent to the point that they couldn't be pulled out of the link.
