Title: what size bolt for rear diff?
Post by: Matt_H on April 03, 2005, 23:14:18: Hello,

I picked up one of those nice wraparound diff defenders at sodbury nice and cheaply but it didn't come with bolts. It mounts to the two holes that are near to where the axle connects (Rear diff - not sure if front is the same).. Does anyone happen to know what size they are as I'm pretty sure they aren't metric.

Would it be a problem to tap them out to the next biggest metric size? Are they meant for anything in particular?

TIA
Matthew

Mine came with the bolts and I didn't pay attention to the size but I'm not sure they were metric (but then it's late). Look on the QT website for fitting instructions as I seem to recall it tells you the bolt sizes in the instructions that came with them.

I'll be back......

Post by: Matt_H on April 04, 2005, 20:48:15: Firstly I'm 99% sure it is imperial. The are not QT but QT copies, pretty much exactly the same minus the bolts - hence why I got them for 1/3 of the QT price.

I believe it is something or other imperial with a fine thread - which I don't have guages for!

thanks for the QT heads up I'll have a look on their website :-)

It can't be drilled out Kev because you would end up going through I imagine the drive shaft input bearings!

Post by: Matt_H on April 04, 2005, 21:13:21: aha that makes sense then! At least I can take a bolt out of the front and take it to a nut and bolt place that way :-)

TA!

Post by: karloss on April 05, 2005, 22:40:30: They are 100% certainly imperial, and I can't find the bloomin tap now! So, sorry not sure on the size, 3/8 something, I'm sure.
