Since I wanted to change the bushing on the Hydro pedal on the floor anyway, I figured it was a good time to think about sealing up and sound proofing the floor of my cab.
After some disassembly what I found was the whole weight of the Seat, Operator, Floor and Fenders rests on top of the transmission, metal to metal. (no wonder all the transmission noise in the cab)
If you look at the first picture the sound proofing was flatten to nothing you can see the outline and because of a weld not being ground off it was hitting the floor causing a worn out mark in the metal floor.(metal to metal)
Also the heads of two bolts were grinding into the floor as pointed out in the photos.
I ordered some Dynamat sound proofing to cover the floor panels, which now rings like a tuning fork when hit.
I want to find some rubber Isolators to place between that plate on the top of the transmission ( shown in the fourth picture) and the floor so all the weight will not be supported by the transmission plate metal to metal.
I can't believe all the weight, operator and all, rests on the transmission of the b3030 cab. Rests directly on the transmission for support. The transmission holds up the floor and nothing else.
I think I have room for a 3/4 inch rubber isolator to keep the floor off the transmission. The cab has four rubber isolators on the four corners But the center of the floor rests completely on the transmission for support, without anything to isolate the noise. Getting the floor off the transmission has to cut down on the transfer of noise, Metal to metal that is what I have now and most likely you do too.
