LMTV Spicer bolt thread

[mildoc]

It appears the threads that the Spicer bolt/banjo bolt goes into are stripped. It looked like it was 5/8" 20thread but that still won't allow the bolt even to start. I looked up the 673998 specs and they don't seem to match up.

Any ideas to the bolt/thread size of this one?

Banjo Bolt size for that # comes back to the following.

Post a picture of what you have.

Thats the specs I found but with a micrometer, it is close to .675 which those specs don't match up to that in any way.

Take a picture of the location and what is stripped out on the truck. Some parts get different variants/ updates depending on WMOs or services done.

I will get that first thing in the morning.

Other number for a coarse thread bolt is 673608. Dunno if those specs help you or not.

Your bolt you posted and the one being sold on ebay look similar in size.

It is for the hose that attaches to the wheel for the CTIS. Where this hose attaches. This isn't my photo, I will take one of my wheel tomorrow but this is the hose I have. The old bolt was completely stripped of threads and barely holding in.

I found this. Now I just need to find the corresponding tap. Looks like .652in or 16.56mm with 18tpi threads.

13/16" tap.

If the hub stud is damaged it is removeable for replacement.

It looks like just the first few threads are damaged. I will try to find a tap to see if I can clean them up and if not, then on to the next step.

So here is the information I can pass on for the repair if anyone has this issue. Banjo bolt is 18mm 1.5 threads. A 16.5mm drill bit isn't easy to find but a 5/8 drilled it out for the tap. I'm not sure what hollow stud was in it before but there was no way it was even close to the 18mm since the 5/8 drill bit took a good amount of material before I cut the threads.

here is another good tip, if you ever need a tap, NEVER buy one from NAPA. they are junk made in China and are not even close to sharp. Will not even work as a thread chaser.

This is incorrect. It is not 18mm 1.5. It is 5/8 18 but not regular thread or NPT. I think it is ORB thread type but am still trying to figure it out myself for sure. ORB makes sense though since it is all made from hydraulic fittings.

It's 3/8 NPSM (national pipe straight male).
