Hi Chaps
I have Hagon shocks on this 400/4. On the nearside bottom fixing the PO has put 3 washers on to move the bolt out by a nano so the end of the bolt misses the nuts that hold the sprocket on. Should I also put a couple of washers on the fixing at the top of the shock, there is only 1 at the moment, so it brings the top out by a nano as well and should I do the same on the offside even though there is nothing for the bottom bolt to foul on ?
Ta in advance
Julie

Hi Julie,
The PO washers were probably to make up for incorrect length bolts, the shocks should line up when fitted as per parts drawing.---Ken

Thanks Ken. That makes sense, I will cut the end of the bolt off.
Thank you
-
I would not be cutting the bolt if it is the right length. what you may find is that the shock eyes are slimmer than the OEM, so the PO has put washers in to pack it out.
-
Ok, I won't cut it off then ::) ::)
-
Somebody who has originals could be nice and measure the length of the bolt and the distance across the outside of the original fittings for you, unless 500 are the same I can't help there tho'
-
M10 x 32 on the bottom shock mount ;)
-
Do you actually measure the head of the bolt,(Sorry Chaps, never have known where to measure from), if you do mine are 10x43 ish, so too long. A 10x32, without the head,would be about 2 mm too short and that not alowing for a washer

Bolts are measured from under the head to the very end of thread

... And so are screws

And some numbnuts ;D

CMSNL show originals as M10 x 32

Many of the fixings have dimensions shown in the parts details so quite handy. The Honda part number also shows size.
Hagon may be different
Originals had a fine (1.25 thread pitch) normal M10 is 1.5
I would suggest shortening bolt rather than extra washesr, dont forget to file end to tidy and create lead in on threads (taper) but if existing are wrong size and the 32mm are correct on Hagon as well, new bolts are about £2 each from DSS and nice and shiny :)

Thanks Martin.

Hi,
Fitted Hagons myself, along with their progressive front springs with no problems.The bottom yokes were the correct gap and thread as per originals, easy way is to try the bottom "yoke" for side play against the swinging arm bushes, and try the fixing bolt before finally putting it vall together!----Ken
-
The bottom yokes of the shocks are a perfect fit actually at the fixing point, no side play at all. I think I will either cut the bolts down or buy some M10x32

I can not be 100% sure because my 400 is in storage but, the 550 and 750 have a chrome bolt for the bottom shock mount.

Buy stainless bolts and polish the heads - probably cheaper than the Honda OE ones.

Std shocks Julie. May be of some use
-
Thanks Tom. They look the same size as my Hagons, I think I'm just going to go with a shorter bolts.
Thanks again
