With reference now to FIG. 23, the handles 16, handle frame 64, and upper cover portion 12 may be preassembled as described herein. As shown, handle frames 64 are first preassembled to each of the handles 16. This is accomplished by providing fasteners 280 through apertures 274 where fasteners are threadably received in apertures 258 (FIG. 22) of bosses 260. This retains the handle frames 64 to the handles 16. A combination of the handles 16 and handle frame 64 is thereafter positioned with flanges 262 on pedestals 220 (FIG. 19). Each of the handles is aligned with the apertures 254, 264 in alignment with apertures 224. Fasteners 288 are thereafter received from a lower side of upper cover portion 12 through apertures 224 to be received in apertures 254. This retains handles 16, handle frames 64, and upper cover portion 12 together.
With reference now to FIG. 24, the engine mount 66, fuel tank mount 68, and housing frame 70 will be described in greater detail. As shown, engine mount 66 includes a mounting plate 300 and isolation mount 302. Mounting plate 300 includes a central plate portion 304 having upstanding bosses 306 with apertures 308.

Isolation mount 302 further includes a stud 330 having a threaded portion 332 extending downwardly through plate portion 322a as described herein. In should also be appreciated that plate portions 322a generally extend through a horizontal plane or through a plane generally transverse to a plane through plate portion 320a. Isolation mount 302 is coupled to mounting plate 300 by a way of a fastener (not shown) extending through apertures 302 and 314.
As isolation member extends between the plate portions 320c and 322c, it also extends at an angle of approximately 45° relative to horizontal. This allows better isolation of vertical and lateral components of engine vibration to be dissipated, rather than transferring the vibration to the lower housing base portion 10.
Fuel tank mount 68 is generally comprised of two mount portions 68a and 68b. Mount portion 68a (FIGS. 24 and 26) includes an upstanding wall portion 330 coupled to a lower bracket at 332 having apertures at 334. Alignment portions 336, 338, and 340 project from a backside of plate portion 330. Alignment pegs 342 and 344 are cruciform in configuration, and extend from a backside of plate portion 330. Fuel tank mount portion 68b is similar to that of 68a including an upstanding wall 350 having bracket 352 with apertures 354. Alignment member 356 (FIG. 26) extends from a backside of wall 350 and also includes cruciform-shaped alignment members 358.
With reference again to FIG. 24, frame 70 will be described in greater detail. It should be understood that each of the frames 70 are a mirror image of the other frame and therefore only one such frame will be described. As shown, frame 70 is generally vertically upstanding having a generally inverted U-shape. The U-shape is defined by an inverted U-shaped rod 370 having vertical rod portions 372 and a transverse rod portion 374. Lower brackets 376 are coupled to lower ends of the vertical rod portions 372 and upper brackets 378 are coupled to both rod portions 372, 374.

Bracket 378 includes a bracket portion 378a coupled to rod portion 372 and a portion 378b coupled to rod portion 374. Plate portion 378a includes a tab 378c having an aperture at 378d. Bracket portion 378b includes an aperture 378e aligned with a threaded fastener 378f.
With reference now to FIG. 26, engine-generator 6 is shown having an engine 400, generator 402, controller 404, and fuel tank 406. Engine 400 includes a lower mounting surface 410 having mounting apertures 412. Engine 400 further includes a throttle at 416. Fuel tank 406 includes a fuel cap 420 and a filler neck 422 (FIG. 29). Fuel tank 406 further includes alignment studs 428 having a cruciform opening at 430. Controller 404 includes alignment tabs 440, 442, and 444. As shown in FIG. 26, engine mounting plate 300 may be coupled to surface 410 of engine 400 by way of fasteners through apertures 308 and 412.
Thus, engine-generator 6 may be coupled to lower housing base portion 10 by positioning threaded fasteners 332 of studs 330 (FIG. 25) through apertures 86 (FIG. 12) and with tabs 322b (FIG. 25) positioned through apertures 88 (FIG. 12). Threaded stud 332 will protrude through apertures 86 and a threaded fastener may be attached to the underside of lower housing base portion 10. At the same time, mounts 68a and 68b may be positioned with their respective flanges 332, 352, positioned over bosses 96 (FIG. 12) with fasteners received through apertures 334, 354 retaining fuel tank 406 and controller 404 to the lower housing base portion 10. At the same time, projections 444 (FIG. 26) are positioned into apertures 100 (FIG. 27) of lower housing base portion 10.
As shown in FIG. 27, frame 70 may also be coupled to the lower housing base portion 10 by positioning lower brackets 376, and more particularly, apertures 376c in alignment with apertures 92 (FIG. 12) of bosses 90. Threaded fasteners may be received through each of the apertures 376c fastening the frame 70 to the lower housing base portion 10. The middle housing portion 14, preassembled as described above, may now be slidably received over frames 70 and engine-generator 6. This positions lower lip 126, 186 (FIGS. 16 and 17) in groove 80 (FIG. 12) this also positions slotted openings 168 (FIG. 17) over aperture 378d (FIG. 27), whereby a threaded fastener may be received to couple the middle housing 14 to frame 70.
Finally, and with respect to FIG. 30, upper cover member 12 may now be coupled to frame 70 by positioning upper cover member 12 over, and against, mid-housing portion. As mentioned above, handle 16 is preassembled to upper cover member 12 by way of fasteners 288, which are positioned on an inside of upper cover member 12. However, aperture 18 together with aperture 268 (FIG. 22), aligns with aperture 230 from a top thereof (see FIG. 7) such that fastener 450 (FIG. 30) may be received through aperture 18 into aperture 230 whereupon it is received through threaded fastener 378f.
By providing the engine mount 66 with the isolation mount 302, the engine vibration is dissipated, having little to no vibration at the outer housing 4. By providing the frame 70 between the upper cover and the lower housing base portion 10, the forces in the handle 16 (from the weight of the generator 2) are transferred to the lower housing base portion 10 through the frame 70.
As assembled, housing 4 is positioned over and encloses the engine-generator 6. Certain features of the engine are accessible through the housing 4. For example, the engine dipstick 460 (FIG. 26) is accessible by removing the service door 36 (FIG. 5) as described above. Also the fuel filler neck 422 and cap 420 (FIG. 29) are accessible through the opening 240 (FIG. 19). Also throttle 416 is accessible through window 146 (FIG. 5).
With reference now to FIGS. 31 and 32, an optional oil fill and drain tube assembly will now be described. As shown first in FIG. 31, the assembly includes a fill tube shown generally at 470 including a tube portion 472 and a fitting 474. Tube portion 472 is comprised of a central corrugated portion 476 allowing the tube portion to be flexible relative to a longitudinal axis of the tube. A top or outer end 478 is internally threaded to receive an oil canister as further described herein. An opposite end of tube 476 includes a sealed end 480, which is coupled to the fitting 474. Fitting 474 includes a threaded end 482, which matches the thread on the dipstick. Fitting 474 also includes a hexagonal portion 484 to be used with a wrench to assist in installing fitting 474.
With reference now to FIG. 32, an oil canister 490 is provided having a threaded end 492, which matches the thread on hose outer end 478. Canister 490 includes a central volume portion 494 and a cap 496.
Thus, to drain the oil from generator 2, dipstick 460 is removed from engine 400 and fitting 474 is threaded into the dipstick hole. Canister 490 is then threaded onto hose end 478 whereupon generator 2 can be tipped to drain the oil into canister 490. Once the oil has drained, the canister 490 can be removed and the oil can be discarded. To add new oil, the oil is placed in the central volume portion 494 of canister 490 and the reverse process takes place where canister 490 is connected to hose 472, generator 2 is positioned upright and canister 490 is tipped upwardly to allow oil to drain from canister 490 through hose 472 back into the engine crank case. Canister 490 could have a fill line, which corresponds to the oil capacity of the engine to ensure that the proper amount of oil is added to the engine.
Another embodiment of the present disclosure is shown in FIGS. 33-37. A handle assembly 500 is coupled to a top portion of the upper cover portion 12 of housing 4 to facilitate movement of the portable generator 2.
