Pretty intense layout. I have a small 10' 8" x 7' 11" area that is more of an L shape to work with. This is before framing. After ripping out drywall, none of the studs are load bearing, just tacked to the side of the joists. Almost did a cartwheel because that means I can delete outright and not have to die. With that gone I might have a 7'11" x 7' and change box to work with after entering the doorway. Gotta find a way to fit a 60" corner tub and a walk in shower in there. I'm going to vent like that as well. Vent is at center of house and new bathroom will be at a corner. Just going to run some 1 1/2" to the corner and 90 back to the vanity drain. I got vanity at top, tub and shower next, shitter last on the line toward the drain. All wyes angled into a main pipe for max flow and the least opportunity for poo water to backup into the other facilities. I need to figure out how to put the backwater valve in. So important. If we were ever in a prolonged period of no power, lets say from a solar flare, wastewater would back up at the neighborhood level. Sewer mains would eventually become saturated and the poo has to go somewhere to alleviate that. So folks without a backwater valve would be the recipients of everyone's doo doo. That is just one extreme example, but hey.
I have a slightly different model. I can not find a way to remove the back plate. I have remived every screw and bolt and have the top off, but the back plate looks almost like it is a part of the sides and bottom.
Get yourself an electric charcoal starter like what the kid puts on the door knob in Home Alone. Works great usually no more than 10 minutes and you can do something else while it does the work for you.
the rollers are not lubed because most lubes are flammable like WD40 and 3 in oil , that and lint landing on the burner housing would catch fire . Sprayon has a synthetic lube that is non-flammable that is what used for this repair
It's fine, change it. Won't hurt anything. Only help. That's an old myth when changing trans fluid and flushing it. Just make sure you use the differential additive for a limited slip if that is what yours has?
The vent TY where the toilet is, is installed backwards. The TY should be installed in the direction of airflow. In this case the 90 of the TY should be going to the left.
