I wanted to check the level of the oil in the transfer case and the allen head bolt is REALLY stuck. I have put penetrating fluid on it and its been sitting for about 2 weeks and still no go. Any suggestions??? Would heating up the case around the bolt help?

 

i managed to get an impact wrench on mine and just lightly bump the trigger as to not break anything

 

I was thinking of that, but the case looks to be white metal and I don't want to wreck it...

 

If you have a small hand held torch just put some mild heat on it then remove heat and spray with penatrating lube, might have to do a couple of times but it worked for me. Make sure you coat it with anti-seize before you put it back in.

 

i have used torches but be carefull the case is alum. give some heat around the plug dont heat the plug itself.. and like skidooer said put anti -snot on it

 

I found a little Teflon tape on the threads does the job of preventing leaks and it doesn't need to be tightened as much. With the case being aluminum and the plug steel I didn't like the idea of having to tighten really tight so it wouldn't leak and have the risk of cracking the case.

 

Thanks for all the info, I'll give it a try next week, have to help the sister move this weekend, but motorcycle ice racing SUNDAY!!!! Little nervous about putting the 6600 lb truck on the ice... First winter with this truck... Sure love that Cummins motor...

 

Make you are using a 3/8 hex socket in good shape and a long handle rachet. You might have to put some muscle behind it, but it will come out. I do a lot of jeeps and never rounded one out yet.
