4 bolt towball mount
hi,
I have a bracket that features instead of 2x m16 holes, an arrangement of 4x m10 bolt holes in spacing 85mm x 45mm. The ball is by brink, which the bracket may also be though I thought it might have been a witter. it does appear heavy duty, though getting accessories much more tricky. i've seen a jaw-ball/pin combo via a google search for £120 which is a bit steep when can get a 2 bolt dixon bates job for around £40. whilst both are rated to 3500kg, the 4 bolts pin was upto 5000 rating somewhat ott for a truck with a max weight of 2800kg?? once saw an adapter for sale that allowed standard 2 bolters to mount and still kicking myself as it also formed a spacer, handy as the current ball position is under the spare with clearance issues for some couplings esp. stabilizer types. looking for any advice, details of dealers of above or better priced ball/jaws as getting to point where might ditch the hitch for a whole new bracket to simplify the mount. only postive thing found to date is that a nato hitch might share these 4 centres but bit ott on t2? thanks richard

Surely if you've got the standard T2 towbar, the cost of a new two-bolt ball hitch and a spacer is just a few quid? I bet you're going to tell me now its a non-standard setup...

got a partial resolve at towsure today, retaining 4 hole bracket, got a stabilizer
receiver plate for a snakemaster blade type. the regular holes will take my m10 85mm centre bolts at an angle within them, am adding a further alloy spacer then an inch spacer for other pair. Atleast ball is starting to come out from under spare, not sure if will need stabiliser but atleast there for backup as not going friction coupling type. only other issue have messed up departure angle with this drop plate but hey can alway take it all off, like dinky does for proper off roading.

Not sure if this is what you are after but here are a couple I could supply but not cheap I am afraid,
One of these for £105.00 + vat American patent. Max Static Load: (6600lbs/3000 kgs on the ball, 8800lbs/4000 kgs on the pin). Double locking system, suitable for 51mm section ring eyes. This Towing Hitch should not be welded or modified in any way. Always use 8.8 tensile fixing bolts and the original safety chain. Lock the hook by fitting the security pin. Never use without the security pin in place. Check regularly for signs of wear or damage. Never replace worn parts other than with original parts. Clean and grease regularly. Or one of these for £95.00 + vat S Value (max):120 (kg) D Value (max):Ball 17.2 (kN) Pin 17.2 (kN) To calculate specific applications: D = 9.81 x T x C (kN) T + C Where C = the maximum trailer weight in Tonnes and T = the maximum towing vehicle weight in Tonnes. S.20777 CE Approved. Max Static Load: (7700lbs/3500kg on the ball, 7700lbs/3500kg on the pin) |

The bracket has 4 holes for m10s, were 60mm got some new 70 and 80 mm to allow for
spacers. TB seen those nato still ball units what a neat idea. I emailed some sellers on ebay and it appears normal nato pintles use my 85 x 45mm centres which means my bracket is obviously HD design. previously found on net jaw/ball combos with 4 bolts for around £120 which is more than twice a 3500kg dixon bate type, so again must be for tougher military or agricultral markets. other night found on fleabay a ball on a thread so could use with that yank pintle, not bad at about £8, item 160315684260 described as a screwball from dealer autocentre of Perth.

i have never seen a tow ball attached with m10 bolts, would use m12 and grade 10.9 or 12.9 would be best http://www.roymech.co.uk/Useful_Tabl...s/Strength.htm http://www.dixonbate.co.uk/Towing/index.asp

nato, confirmed with a nato seller both private and dealer john craddock well known in green oval circles! to fit larger would mean drilling out tow bracket and existing forged brink ball so think not, getting closer to their outside edges. Imagine that spread load, as per surface area of 4 m10 is greater than 2 m16? ref DB link try this http://www.dixonbate.co.uk/towing/pr...?PartNo=201691 a 5 tonne combo is what i can fix on, thats one previously seen at 120 quid!

fair enough, must be down to distribution, as said if good enough for a pintle or a 5t hitch will do, atlernative is ripping brack et off and fitting something else that terminates in a pair of m16s, or weld on a receiver tube and go yank slot in route. will do for now, already raised receiver issues with Scott, as per front towball fitting, see how that goes as at mo, running round with new ball on back feel quite naked and vulerable afterall cant tow if need too....
