Hi folk,
Firstly the bike belongs to a friend of mine and I'm trying to help him restore it. Secondly, in my defence, I wasn't there when he dismantled the wheels, so no photos until we dismantled the rest of the frame. I always do. I learned this the hard way when I was working on my 1969 Merc 4cyl outboard the first time :(:D.
Bike is a 1982 V35.
Problem one: Pics we've looked at for V35s on the web show the calipers front of forks, under the headlamp, and back of forks, back towards the engine block. Which is the correct way? We have tried it both ways.
Problem two: When we put the spindle in with the washer and spacers as per the manual, there are gaps either side of the wheel between it and the forks so as when the spindle nut is tightened the brake discs bind on the forks. And gaps either side of the wheel which, if the bike was moving, the wheel would move from side to side, that would be a hairy ride:D . Spindle head end is flush with the fork.
Problem three: Calipers will not mate with the mounting bracket, gap of about 1/8".
If anyone could post a pic of the correct orientation of the calipers and sequence of the washers, spacers and speedo, which I do know goes on the righthand side of the bike, it would be very much appreciated, thank you.
 
Pics are most helpful. It sounds like it may be a replacement front end.
I am not well-versed in the old small blocks, but I'm sure many others here are.
 
Thank you for the reply. I'll get pics at the weekend, not in the vicinity but I'm told that it is all original. I'm not really very tech savey :) so it will take me a wee while.
 
Make sure you have the correct axle in the forks to start with, may have a wheel from another model.
Just looked in my green book that covers V35-V65 and all calipers are on the rear of fork legs and face the motor.
Todd has one of these in the download section if you look, so you can compare what you have & what model smallblock it came from if it was replaced.
So you know, they make shims that go between brake caliper and fork leg mounts. They are to center the caliper on the disc.
These should be in the parts book, if not look in the parts book for any bigblock from that era.
 
"So you know, they make shims that go between brake caliper and fork leg mounts."
That makes sense, That's another thing I'll have a look at.
And I'm really looking forward to the electrics :D. Thank you
 
Calipers in front of leg - up to , say 1982, V50II - V35. Later - calipers are behind the leg, V50III - V35II and all the rest. Re spindle gap. It happens that slight hit(wall, other vehicle, possibly high kerb) bends the forks just slightly, not noticeably. And then, by twisting the leg in yokes you may unwillingly set that leg-to-leg distance differently. I did that, anyway! Re calipers mounting holes, there re again, depending on model, two different brake disc layout - flat disc/thick hub, as in late 90's Nevadas and 16' front wheel V35III, and deep-pressed disc/narrow hub in most of the small block. If you mix them up - that causes the problem. Also, tell us, what is fork tube diameter? it should be either 32mm(calipers front or rear), or 35mm - calipers at the rear only.
 
I'll measure them on Saturday morning and the hub as well. That is great info, thank you.
We came to the conclusion that the bike has been dismantled in the past, so now I'm hoping it hasn't been frankenstiened
 
The storm took out the power but I got the measurement, 35mm, so calipers to the rear.
I think we also worked what I was doing wrong with the spindle, I hope. Power won't be restored until tomorrow evening at earliest.
