Thanks for the diagram on the wiring as I know that will be valuable to me on more then one occasion.

Yup, looks like 6 screws from underneath on pg 40.

Re: rc4wd 870k loader
 

Thank you for the pages on the loader, guess that explains the sounds quality. Theres a chair using a speaker for a seat.. maybe I can turn the seat into some sort of a bass box. looking into a better quality speaker that will fit. keep ya posted if I do. thanks again for the much needed info.

Re: rc4wd 870k loader
 

Lenny, did you find a better speaker alternative? Stock speaker appears to be 45mm or 1-3/4" diameter.
My beier sound card may have over powered the stock speaker and caused damage. Any tips or speaker alternatives would be appreciated.
Thanks

I have a speaker from one of my Lionel engines.. it's laying in the rear hatch facing out the left side vents which is nice for sound. Just no need to remove the cab yet so thats the way its been.

Re: rc4wd 870k loader
 

there are 4 screws to remove the cab 2 are in the front of cab 1 is in the front of the hydro tank the 4 screw will take the whole cab in 1 piece i believe but i had to remove all of it i will not get into the problems i have had and still haveing i have the it apart from front of cab to the rear bumper hahahaha:jaw::mad::mad::mad:

Re: rc4wd 870k loader
 

Thanks Jack, and Lenny.
I removed the cab. Sure enough my speaker was damaged from over powering. It still works if I apply small amount of pressure with my finger on the speaker cone. So I looked around and there is not much choice for a 45mm speaker. I ended up getting this on ebay and I'll cut the ears off. I hope it fits. https://m.ebay.com/itm/2pcs-1-75-quo...=1721787650006

Re: rc4wd 870k loader
 

Success story. I ended up getting the speaker off of ebay (link to speaker information in previous post.) I cut the ears off and it fit perfectly into the existing opening underneath the operators seat. I noticed the edge of the speaker was being pinched and restricted of free movement against the black plastic housing. I used a dremel and cut an angle at the 4 areas i have circled in red. This allowed the speaker's edge not to touch the black plastic housing. I believe that was part of the cause for the original speaker to fail. The other part was the original speaker being 4ohm and it should be at least 8ohm according to my sound card's manual at the voltage I'm running it as.
The new pair of speakers i received don't seem to have any strength of magnet.?? Whereas the original speaker's magnet was quite present. Not sure how speakers work but I thought all speakers need magnet?? Regardless, the sound quality is more or less the same as the original.
