Hi,

Just about to do my GU wheel bearings. If anyone has dimensions so I could make a spanner I'd appreciate it. I know they are now round with a couple of dowel pin holes.

If not, when I make one I'll post all the dimensions needed. Would just make it easier for me to get them first.

Thanks

If my memory is right I believe they are 53mm apart for the pins. Might pay to do a search

Being a pain I know but-

So 7mm pins, ID 42mm, OD 45mm. What length of pipe if I want to clear the stub axle and drill holes in the end of the pipe to make it like a T-bar????

Thanks again.

Thanks for the help Robin. Made the spanner and used it on the weekend.

Found that the nut was very tight, unlike the GQ bearing nut. I had to loosen it with a hammer and to get it to the same spot so the locking nut could be screwed it I had to tighten it with a couple of taps with a hammer.

Is that the norm for the GU??

The one I made has 7mm dowels, 52mm apart (centre-centre)... Pins need to be about 55 - 60mm long to clear the axle stub...

Mr Gregory (Manual# 519) recommends a pre-load torque between 167 - 196 Nm (123.5 - 145 lb ft).. If you follow this recommendation, I'd suggest using at _least_ 1/2 - 9/16" dia. (HT bolt) for the dowel pins (w/- the ends turned down to 7mm to engage the nut)...

Have fun;-))

Hmmmmmm,,,,,,,,

"167 - 196 Nm (123.5 - 145 lb ft).. "

Sounds about "one good belt and two little taps" with 2lb hammer and chisel ;)

Well, that's how i used to do the Mav wheel bearings and they never packed up!

Austravel,

The socket for the wheel bearing nut is not that expensive. The one I have is more of a tube socket and is strong enough to tighten and loosen the wheel bearing nut.

The one I got had a 3/4" drive, so I welded a 1/2" socket into the 3/4" drive and this also works fine.

Having the right tool for the job makes it a lot easier and I would check and repack the bearing more often having the right socket.
