Top rear wishbone mounting space!?
Winston Todge - 26/4/06 at 11:46 AM
Hey all just as the title really...
I'm fitting the rear end together and have come a little unstuck with the rear wishbones. The top rearmost mount seems to run very close to a
vertical chassis tube.
Do people use a shallower nyloc and a shorter bolt?
Ta,
Chris.

Yes a shorter Nylock nut is required the bolt may need to be checked for length as well .
I assume this is the top rear most bolt that in getting close to the bar that the fuel tank sits close to.

Is that the one where MNR supply crushed full nuts rather than nylocs. They were a bit of a pain to fit but not as much as the rear uprights.
Winston Todge - 26/4/06 at 07:32 PM
Thanks for that guys.
Can't seem to find any crushed nuts for this purpose though!?
Also my top wishbone seems to be very tight on the two inner wishbone brackets. Has anyone else found this? The brackets seem a little too widely
spaced for the spacing of the wishbone...
Any comments people?
Chris.

Yep they are tight. How many mm do you recon you need ?
couple of things to make shure are the brackets you are locting the arms into 'Square' to the chassis ? .
Are your rubber bushes fully inserted ?
the edge of the bush should mate with the tube vitually no gap. check for over zealous powder coating ?

Just tolerance on the wishbones, but if they are way out, marc did have some wishbones that were made wrong, but they were RT+ I believe...
He had to redo mine and repair his jigs which someone screwed...

Again great points Ian.
All things you suggested I've had a squizz at. The slight worry is that without any bushes in place the wishbone fits into the two brackets but
only has a mil between the inner wishbone mounting face and the bracket.
Also both top rear bones seem to have a slight toe in to them. Would this have an affect? Is this normal?
My wishbones are slightly different as they have the stiffening brace that runs across diagonally also.
Any more ideas?
Chris.
P.S. I could probably fit them in but it would be very tight. Would this have any adverse affects?
Winston Todge - 26/4/06 at 09:35 PM
They may have been the same Marc?
What were the problems with the incorrectly made ones?
Ta,
Chris.
Agriv8 - 26/4/06 at 09:53 PM
Right,
jigs for RT + and RT are different ( i think )
at MNR tommorow as we are prepping up for the show ( also need to get a couple of fine tunnung jobs sorted on the v8 ) will have a word with mark and
get back to you.

)

Wasnt the same as your problem, I think yours are just at extremes of tolerance...
A jig is very accurate, but I found when building mine, it does have some bits that arent 100% consistent, the brackets are only bent metal after
all...
Its nothing that causes a problem longer term, but if you have brackets at the outer edges of their tolerance, and wishbones that are at the slimmer
edge of their tolerance its gonna be a tight fit...
Which is what yours is I think...
Winston Todge - 27/4/06 at 05:58 AM
I think I may just be being a little picky to be honest.
What are the effects of a tight wishbone?
As you said earlier Ian, it's important to get the polybushes in flush against the side of the wishbone face. What happens if these are squeezed
a little by the nut and bolt?
I think what I'm trying to ask is when the bolt is inserted through a polybush and crush tube what should pivot when the wishbone is moved up and
down?
Should the polybush stay stationary and the wishbone pivot? Or should the wishbone and polybush pivot on the crush tube?
Thanks again,
Chris.

Apparently this is a matter which can cause lengthy discussion and much name calling. I'll risk it though and say the above.
Bryan Sears - 27/4/06 at 02:40 PM
When I fitted my suspension I found that I could make It fit by standing on one end of the wishbone and pulling it with both hands to make the gap
wider not very technical but it made it fit hope this helps.
Krismc - 28/4/06 at 04:09 PM
I have the same clearance issue on my up rear most (inward) bolt, i didnt fancy cutting the bolts down but if thats the only way then hey i better get
on with it, what about the nut??
Agriv8 - 28/4/06 at 08:19 PM
Winston Sorry for the delay in geting back to you mentioned to mark .
You need to 'tweak' your rear boanes as mentioned above pulling them apart as Mark suspects they have pulled when they were welded up a
small tweak should sort you out.
