Wonkey headlight!

Aprilia Caponord ETV1000 Rally-Raid headlight adjuster screwLast year the tester at the MOT station didn’t like the slightly low headlight beams (set to offset loaded panniers) and wanted to raise them. Unfortunately I think he raised the left-hand to the point of possibly unseating the ball at the end of the adjuster screw from the reflector. Friction alone on the other pivots probably only holding it in place to his satisfaction. About a month ago the same headlight went out of vertical alignment a little, then  finally the other evening, suddenly dropped completely (and very noticeably!) so the low-beam was now tripping over the front wheel!

First check – bulbs out and try to move the reflectors up and down. Right-hand no movement – fine, left-hand very wobbly, plus the adjuster unscrewed completely by hand. So, headlight out as it’s far easier to work on.

Remove the rubber gaiter and bulb and a visual check of the reflector mountings is possible – they looked OK, so I cleaned up the adjuster and applied the lightest wipe Aprilia Caponord ETV1000 Rally-Raid headlight reflector adjuster socket and clippossible of grease on the ball to help it seat more easily, I honestly couldn’t have applied less if I’d just shown it a photo of a grease tub! Then screw in the adjuster and kept going (very gently!) a half turn at a time once it had seated against the reflector socket. I also used a little brass-tool to help pull lightly) on the reflector mount to help the process. I guess I went about three full turns before the ball made a loud ‘pop’ and dropped into position. I don’t know which was more relieved – the stresses in the reflector or my pulse-rate!

I did them one lamp lit at a time, then double checked with both lit and also checked the horizontal alignment at the same time. Total time about 10 minutes and hopefully a happy MOT guy in a few weeks time!

Aprilia Caponord ETV1000 Rally-Raid rubber shield for dashboard lower and headlight 8158255Buttoning it all up went OK, but it was obvious the rubber dashboard lower/headlight shield has finally seen the best of its days with numerous splits starting. So a template was drawn, then reproduced in CAD and some 2mm rubber sheet ordered from Flea-Bay – cheaper than Aprilia, who want over €60 for the same part (AP8168916)!
