DBXL 2.0 Dbxl 2.0 intermediate shaft cup loosing set screws.

[Rep732]

So I just want to post an issue i had to fix for a customer and also show that I have my hands on these things just as much as you guys.

So the issue I have come across is the intermediate shaft cup lost 1 out of 2 set screws and 1 backed out which caused it to pretty much be front wheel drive.

I advise anyone with a dbxl 2.0 to immediately pull them out and use red loctite and tighten them down good before you run into this issue. It seems losi used some sort of loctite but not one if yet seen as it resembled dry pudding really it was crusty and lacked any adhesion to the metal.

I took it one step further and drilled into the shaft a little to give the screw a countersunk hole to bite into so it's up to you guys if you choose to do so but at minimum check your intermediate shafts.

also the rig has about 30 minutes total run time and the pull start broke so I added my cable pull start to permanently fix that issue.

I pulled out all 6 driveshafts on my DBXLe and put a smear of red loctite on the pins also. I always do that to shafts with removeable pins/grubscrews. Holds them good and proper, and they just need a bit of heat to remove

My dbxl don't have any lock tie, lost 2 set screws. Brand new, not even a drop of fuel. I have to rebuild, check everything

That middle cup is so stupid. This happened to a guy last Sunday.

Hey. This happened to me. What should I be doing? Tear this whole thing apart and rebuild it? I mean. . . Going after the diffs this weekend for sure.

I gave an explanation on how to correct the issue.

Guys, can you give me the exact name/type of the red loctite you use? What temperature is needed to "soften" the red loctite for removal of the pins/screws? Thanks

 

[Rep732]

Red loctite #271. The set screws are larger so you should be able to get them out with little to minimal heat.

Butane torch works fine to soften the loctite.

I found this guideline for removing red loctite https://www.henkel-adhesives.com/my...ations/how-to/how-to-remove-loctite-2620.html
I guess that a hot air gun might suffice. It is important not to overheat the steel as it might effect the heat treatment.

@Rep732 Can you remember what was the drill bit size you used for the countersunk hole? Thanks

 

[Rep732]

@rajul I don't but you can just take the grub screw over to the drill bit case and find one that matches the screws counter sink. The screw size m6x1.0 if I remember right.

It's almost like I learn a lot when I read the whole thread and aren't sweating.

Knurled cup point M6x1.0x6mm set screw, blue loctite and a little bit of ass on the tightening. let her sit for 24hrs and you should be good to go.
