Push or pull.
Hi, M Rust.
The slidebar was found on the 1H, 8R and early 2U series D8's. Some D8's, notably the early D8H's, did not have oil feed to the final drive bearings when travelling in reverse. I don't know how the oil feed would have been set up on whatever slidebar D8 you have but I would check before I towed it any great distance backwards.
You may also find that tying both steering clutch levers back will make it easier to steer whether pulling or pushing.
I can't recollect ever seeing a front pull hook on a Cat attached direct to the engine oil pan. They always seem to be attached either to a belly pan or to a separate pull frame if no belly pan is fitted.
My personal choice would be to pull it nose first, even if you end up with a bridle of chain hooked to each side of the equaliser spring in case the front pull hook is not strong enough.
Just my 0.02.
You have a wonderful day. Best wishes.
