Small Disaster

[gordon lonsdale]

Last weekends main job was to fit a new front wheel bearing to the old mk2 diesel,painful story cut short ...head of bolt securing hub carrier to strut shears off... after a lot of drilling from both ends finally got the hub carrier off only to find that I've made the hole with thread oval and removed half the threads . My first thought was just to fit a longer high tensile bolt and a nut but I'm worried about the half to threequarters of a mill of ovality .Its still in bits and I'm wondering about fitting a whole second hand unit ( bearing and all )...............Any thoughts chaps ?? ps would a mk 1 hub and carrier fit ??

Belzona?

 

Drill and retap to larger size?

 

Is the threaded "hole" just a nut welded on the strut? In that case could you hacksaw or chisel it off?

 

I'm sure you could repair it - go along to your local engineering workshop and see what they can do for you.

Hello Seatkid , What is Belzona ? A small spanish town perhaps ? or is it a SEAT based code ? ..anyway the threaded hole is for the bolt which clamps the hub carrier to the strut , luckily the strut is unaffected.The strut passes through a large hole in a sort of extention to the hub carrier forging and forms the upper fixing and locating for it . The lower end is secured to the swivel on the wishbone . Interesting thought here ..do engineering mahine shops charge the same hourly rates as garages?..comments invited .

I wouldn't go the Belzona route, it will never be strong enough.

 

Drill and tap to a larger size would work well in theory, but from memory (which is not A1) there isn't a lot of casting to enlarge the hole into.

 

IMHO, you have two other options open to you. First of all, and preferable, is a replacement hub carrier.

 

Alternatively, you could drill out the threaded part of the hub carrier to a clearance hole and grind a flat at the exit hole for a washer and nyloc nut. I would recommend a fine thread for the bolt and nyloc nut. It's a bodge, but it should be secure enough.

 

Personally, I'd look for a hub. :lol:

Likewise, get a new hub. You can pick them up from a breakers for under

I'm with sparky paul and Mirez on this one don't make do with a repair that if goes wrong could be very dangerous..... go on the parts find network and pick a 2nd hand one up... Edited December 23, 2009 by robpol

I reckon a 1/2" bsf h/t bolt and nut could take up the ovality but you are all so right about possible consequences..taint worth the worry for

Thanks for that robpol, mines the other side grr .I have to say I'd prefer to pick it myself rather than post,just to make sure ,(call me cautious).....(call me tight). Thanks again gordon Ps what is belzona???

[robpol]

Ps what is belzona???

 

not sure on that one personally....

Belzona is marvellous stuff, metal repair putty. Used in industry extensively for your kind of problem.

 

do engineering mahine shops charge the same hourly rates as garages?

 

I always go in to my local 2 man engineering workshop and present the problem (usually specialist welding repair) - depending on the weather it costs between
