I had a bearing fail and trash my 4.7:1 gears in my marlin crawler toybox doubler. I know its a long shot anyone has these as not many were made.
Im running currently 13bt-h55f-toybox-split case and its fantastic. Figured I'd post here before I spend all the money to try and get back to low gearing in other ways. Other very expensive ways...
Let me know if you'd part with yours or alternate ways that I can keep the 13bt and still be lower than 150:1
Thanks! Wish me luck!!

Did you already try contacting Marlin Crawler? Don’t the Toyboxes use the regular 4.7 gear kits for a pickup and just have adapters that make them LC-specific?
 
I have talked to a few guys at marlin. The gears they believe are the same, but the one gear which i have pictured is special to the landcruiser. It slides onto the output shaft of my h55f and they haven't made it for many years one guy said.
I believe the current 4.7:1 set they make for mini trucks or tacomas have a male spline that goes to the transmission where mine is a female 19 spline that goes to the transmission.
Ive contacted a few companies that have gear making abilities, but no word back yet. Im guessing it will be far too cost prohibitive.
Having the toybox to split case has been phenomenal. I hope i can get back to it!
 
With almost no parts availability I’d seriously consider just putting low gears in the split case, obviously you won’t get as low as you’d like but you do gain the ease of fixing on the trail if something breaks. What sucks is having to redo drive lines with the above scenario I mentioned.
 
Im very much looking into a 4:1 sumo kit from cruiser outfitters. I'd be just over 90:1 Thats pretty good, but pretty far from what it was.
One big problem is though when you install the toybox you chop off some of the h55f output shaft so id need to get a new output and rebuild the h55f.
I do have a 40 series shifter for the h55f that I could sell to help fund this.

It's a long story, but that company stole $55k from me at my last employer. I sent them an industrial gearbox for repair from one of our tunnel boring machines. They literally MIG weld repaired a broken gear and "finished" it with an angle grinder and spray painted the case. They didn't even drain the old oil and clean the broken gear bits from the case. One of my vendors who did surface grinding for some of our parts was also taken for $45k on a gearbox repair they took on for a customer. Same deal, 3rd world style "repair" and some spray paint. There is a nationwide network of gear repair companies that are a complete scam, its pretty wild. You can do a deep dive and find MANY similar stories to mine.

100% it is my fault for sending them payment in full prior to pickup and not doing more due diligence.

I’ve always wanted a toybox. But I find it very practical to use crawler gears instead. Especially if toybox parts are hard to get. 4:1 gears can be loud at first but work great. I have h55f, AA 4:1 set, and 4.1 diffs on 33s.

But I digress, hopefully you get this sorted! Having several sticks is cool.

@rusty_sherpa was the machining of the case for the 4:1 set tricky at all?
