DriveShaft Adapter Question

[Goose]

I have a TKX and IRS and got sent a driveshaft adapter that looks like it fits. However, the socket head bolts stick out from the adapter and make it so the driveshaft won't be flush on the adapter. Is this correct or am I missing something?

Not sure what's wrong but the bolts should be flush with the adapter.

The c'bores should be .390" deep and .635" diameter.

It's not clear to me what the issue is from your photos. Are the bolts seated all the way in the counterbore and the heads are still too tall, or is the knurling on the bolts hanging up on the counterbore and not allowing the bolts to seat all the way? To me it looks like the latter.

Ah Rookie mistake on my part... Thank you for the input. The heads are a bit thick and just needed some persuasion from a hammer. I was just looking ahead and making sure everything fit and I have the right parts but I got a bit ahead of myself haha.

Do you mind posting a picture of the persuaded parts so I know what it should look like?

I had the same problem
The bolt heads are too big for the counter sinks in the adaptor
I ordered new bolts from McMaster-Carr
Problem solved

Also you may want to make sure to check the bolt circle on the Adaptor compared to the Diff
I went round several times with the folks at F5 till I got the correct one

Here ya go! Nothing a hammer couldn't fix to help push them in.

Agreed! I saw many people having that issue, but it looks like mine lines up!

Now push them back out and reduce he diameter of the heads. W/o a lathe you can chuck the bolt in a drill and hold a sander or small grinder against the outer surface. If the bolts are tight in that bore your torque readings will be way off and the bolts will be torqued to way less than they should be.

Just curious.... How about chucking up the bolt while IN the adapter and spin it there. Would the knurling on the bolt head open up the hole enough? Or wear down the knurling enough?

[CraigS]

That might work too. As long as you can get enough clearance so it spins freely by hand you will be good. I suspect you only need to remove maybe .005".
