I just finished the seal replacement rebuild on a cab tilt pump on my M1078A1 circa 2006. Two quick thoughts.
1) Leave the reservoir mounted. Just pull the heaver Gage steel formed cover / guard to access the top of the pump assembly. Remove the hoses then remove the 6 10 x 24 hex cap screws and lift off the lid with the pump attached. Waaaay easier than trying to get to the 4 x 8 mm that secure the reservoir. PITA to get to rear pair of these bolt. If the reservoir is nasty mop it out.
2) Post rebuild I was still getting a tiny bit of hydraulic fluid out of the sintered brass exhaust filter. I removed the filter, replaced if with a Push lock style tubing fitting and ran ~4 ft of 3/8 plastic tubing down under the chassis. Now any blowby is exhausted onto the ground without making a mess at the pump at a high location that runs down and makes one wonder *what* the hell is actually leaking. I'd suggest at least 3/8 (od) tubing. If the exhaust is too restricted the pump will cycle slower.
Sorry no pics. Happy to answer questions.
