Went to swap ring gears on my quaife and 9/10 of the ring gear bolts came out difficultly and stripped out some threads on the quaife. Called up Quaife and they do not have any gsr diffs or extra parts for the gsr diff available.

I could tap and helicoil it but its reverse thread and I cant find a reverse thread tap/helicoil kit anywhere. Does anyone have extra parts from a blown up quaife perhaps or know of any other solutions?

Thanks for the help guys.

 

..Bring it to your local machine shop. they should have what you need

 

i have the left hand thread tap if you think that will work

Is it 11x1.0 ? (thats what I think it is). If the local machine shop doesnt have one then I'm on my way to PA dave!!

EDIT: I think the threads are too messed up to just run a tap in them, I think it needs to be helicoiled.

 

Good luck tapping one of these, they are HARD...

Seriously. Send it back to Quaife and have them clean the threads up. You have a small chance of killing the threads when using the OE bolts. They are much softer and will yield long before the quaife unit will. I have had customers bring me diffs like this...I will look to see where I bought my tap from.

 

usually the bolts strip when you take them out, not the diff itself.. ill stick to my $350 obx lsd's

i have noticed that as well. but if you loosen them in 2 or 3 stages, you will not strip the bolts out

i usually just zip them out in a couple seconds with the impact and then just get new bolts.

they strip because they are such a fine thread bolt and they are torqued down alot. but i still dont see how the diff itself stripped out unless the bolts were installed wrong to begin with.

 

almost all of my bolts striped last year when we pulled the quaife from my ls tranny to put it in my gsr. Dave had his tap and he went through each hole and it has been holding fine.

Does anyone know if arp makes replacement bolts for this?

wait..... you said the bolts stripped and then you said you retapped the diff ??

I have seen this problem even with OEM diffs. You need to loosen then in stages and you will have no problems.

Yes the bolts themself stripped and we ran the tap through the threads to clean them up. The quaife was pretty much fine. The bolts were pretty much smooth.

 

Matco thread chasers FTW

 

Anyone know for sure what size tap I need? 11x1.0 perhaps?

 

ITs a 10x1.0 LH tap.

 

here is the screen shot of the OEM sevice manual... ever wonder why HONDA would suggest something ? gotta be a reason.

 

So no one believes in heating the bolts with a torch? I do this every time I install a ring gear and have never had to order new bolts from honda......or ever hurt the threads on a diff

 

i think putting that much heat to a fianl drive might be a little un safe.

Ehhhh, I'd be a little iffy on doing that. Last thing you need to do is overheat it and warp the diff.

 

Im not talking oxy-acetyln. Just a normal propane torch. Never had a problem and I've done quite a few (25+) like that and most in turbo applications that see they're fair share of abuse

 

In the last 2 months I took apart 2 GSR, 1 B16 and 1 LS tranny and I had no issue with any of the diff bolts, broke each one loose all the way individually in no criss cross pattern must of been beginners luck.
