1980 LWB 280GE
Figured it was time to break this out to a new thread. And maybe get some sub-topics going underneath.
All internal components of the 280's trans are physically larger, including the overall length of the case being longer. I once thought I'd swap the trans in my 280 for a spare one I had out of a 230GE. Since the 230's trans was the same as the 300GD, I thought it would be built to take high torque, but it turned out that the 300GD's OM617 had lower peak torque than the 280GE's M110, and after looking at diagrams of the two transmissions, I decided the slightly nicer gear spacing of the other trans was not worth the risk of using the trans designed for lower torque motor.Iver460 - 2/25/2005 5:16 PM
Dave, do you know in which way the 4-speed 280 GE trans (711.1) is beefier than the other 4-speed (711.2)? I believed the higher gear ratios were the only difference.
There are a bunch of differences between the 617 and 617A motors. Most important is probably the spray oiling of the pistons to dissipate heat induced by the turbo. That extra 100 Nm of torque doesn't come for free after all. There are also some nice changes to the preignition chambers to make them more robust and ease cold starts. The rest of the changes (I have the product intro manual that details a hundred or so pages of them) are pretty inconsequential.aggragated - 2/25/2005 4:42 PM
Besides the turbo, I don't believe there is much difference between the turbo and non. If there is please educate me.
The turbo kicks in only when you floor it.
In most driving situations your not using the turbo and you'd better hope it doesn't kick in on a rough trail or control becomes a issue followed by body work.
I guess after a turbo motor blew and sucked the oil out of a engine my views changed on why I needed to get where I was going so fast. The "Benz" knew what he was doing when he began . Simple is better
Have you used a "zero balance" replacement part flywheel in any of your conversions? One fellow here who puts these motors in Mogs a lot says it's fine to slap the zero balance flywheel on a motor that came with an auto box. I have some conflicting feelings.warren t - 2/25/2005 6:07 PM
....you will have to rebalance flywheel.....
Can this be done with a certain part number motor mount bracket on the engine or does it require cutting and re-welding the chassis motor mounts, or manufacturing bespoke engine brackets? If chassis mods are required, I'd sooner blister the oil pan to clear the pumpkin. If you'd like to sell me some brackets for repositioning motor mounts, I'm listening.....engine must positiond properly for sedan oil pan
to clear front diff....
Not as far as I can tell. Mine seems to be level across the cam cover. Might be tipped up at the front a bit, but I'm not sure if that's real or just an illusion of the engine bay.warren t - 2/25/2005 9:19 PM
....when automatic 110 engine leans to left, is this
the case with manual trans....
