I bought a D8K for use on the farm. No operators manual of course, so still figuring things out.
The temperature gauge has three overlapping bands, green, blue and yellow, all ending in red at the top end. I'm assuming the different colors represent different operating conditions? Fan forward vs reverse? Winter vs Summer? It does run much hotter with the fan pushing forward, even on a cold November day.
Are there internal adjustments on the brakes, ( or clutches), or just the external linkages? This has the combined clutch and brakes on the levers. Which work fine, but brakes seem to be at the end of the stroke on the levers, and the left foot brake doesn't function at all. Any specific instructions for free play when adjusting them?
What is the difference between Cat's Transmission Drive Train Oil, and the transmission hydraulic oils for tractors? Would any other oil not be compatible with the clutch linings, or not have enough EP additives? The TDTO oil ended up being hard to source locally, more expensive, and I already keep trans hydraulic on hand.
By serial number, this is supposed to be a spacer plate engine, any way to confirm that visually? And do they require any special pampering to avoid the known issues?
When shifting the powershift under load, it nearly comes to a stop before shifting, which can't be good for the powertrain. Is that normal, or are there accumulators that could need attention, or pressure needing checked? I mostly avoid shifting it under load, instead decellerating and changing the gear, letting the torque converter take the abuse instead. Are they intended to be like any other powershift, and designed to shift all day long under full load?
It will coast on with the decellerator fully depressed, does that indicate it is idling too high, or is that typical?
I can't access a parts book, but if i understood a previous thread correctly, does this have chain drive instead of gears in the final drives? My neighbor who is an Cat skinner from way back, but only ran 6's and 7's from the same era, thinks that the final drives are noisy/whiny compared to what he remembers. Nothing untoward in the oils, both sides make the same sound, don't really notice it from the seat. We have an old tractor with chain drive rear end, and it sounds much the same.
Lots more questions, but that is more than enough for one post.
