18 speed back box disassembled. Grinding low to high. See and understand why🧐

Watch me disassemble a customers Eaton fuller rtlo18918 back box. This customer was complaining of hearing a grinding sound once he flipped from low to high. In the video you can see what it takes to disassemble the auxiliary section of the transmission. I don’t know if you can tell in the video but this auxiliary section was extremely hot. This is only a tear down video leave me a comment I’f you would like to see how an 18 speed back box is built

Interesting video. Looks like you do this on a regular basis as you know exactly where to look for the problem. Try cleaning up the shop as a clean shop goes a long way in inspiring confidence in what you do. Thanks for sharing

Holy cow, think this guy has taken a few of these apart ? I bet he puts it back together just as quick.

Nicely done 🎉🎉🎉🎉🎉🎉

[@gerardomorales1671]

Nice work man, im currently doing one of this but in my case it was grinding from high to low ( low synchro went out, brake material wore out)... You seen like youve been doing this for a while... Im putting all new bearings in and also rebuilding the air cylinders, new synchros and maybe a balance shaft as one of them looks like its got a tiny crack or scratch i will have to look deeper, any recommendations on where to buy a rebuilt kit that would include most of the parts I need?

[@matthewjones8620]

Really enjoy the videos. I would assume that you could extend the life of the synchro's by going to neutral and back in gear with every split vs leaving it in gear for a split?

[@jimslocum6500]

Is the shaft for the splitter with the fork on it aupposed to turn or not turn? When i tried to take the 3/4 nut off of mine to do o rings because it was leaking and wouldnt split, it just turns and i cant get the nut off. Just trying to find out if the shift fork is welded or pinned on the other end...

does a meritior 10 speed come apart the same way? thats the same thing wrong with my dads truck.. but his kicks it out of gear in high range.if not do you have a video for the meritior 10 speed? thanks

[@ironhorseindustrial8562]

I have an 18 speed that grinds and will pop out at the highest/last gear (18 gear?). Shifting through all the other gears are fine. Does this sound like a synchro or something else? Do I have to remove whole trans or maybe just back half? Thank you

[@maxenra]

What would cause grinding between splits on a 13? For example 5h to 6l. Normal range shifts just fine only when splitting the rpm’s drop way too fast to catch next gear while splitting up. Downshifts fine. Thanks!

[@tubeup]

If your bearing covers leak can you simply just replace the gasket, would i need to drain the transmission before changing ?

[@vaillimo9134]

So my 13speed grinds when I shift from high to low. It basically won't hold it in low range when selected. Its worse in the morning and gradually starts working fine once the tranny and truck get hotter. Whats my issue you think? What can I replace or check without removing the entire tranny? Thx 🙏

[@mexicanmexican8682]

Can you make a video on how to convert 13 speed transmission to a 18 speed transmission

[@ISLANDTRUCKER]

Same problem I'm having with a 13 speed. Transmission grinding from low to high.

[@North49trucker]

thanks for the video, im thinking this might be my problem, I already changed out the external parts, and it didnt fix my problem, and the air pressure is good. do you have to drop the entire trans to get the back box off?

[@rickyrobertson9874]

The PULLER point goes in that center hole on the primary shaft, and bolts to the u-bolt's holes. I would have gotten drawn and quartered if I used a hammer when if our shop or someone in our shop had THE TOOL to remove or install.

[@hardhead7056]

What if it only grinds when you Preselect the range before pulling it out of gear? Like the shifting placard tells you to do.

[@truthseeker2190]

Good luck putting that yolk nut back on now after striking the shaft with that steel hammer

[@lizfails5607]

Can u take the Tran top plate off while still in the truck through the access plate in the floor

[@J.R.R-v1c]

My rt14614 Eaton 15 speed is sending air from my deep reduction cylinder to my shifter making it leak but when I put my splitter in the forward position the air stops but I have no deep reduction gears why is this happening

[@RobertJr.-fw7fb]

can that be done without removing the transmission??
