Um. Six in the case of the upper union on my old condenser unit. Own fault. After being delayed by a few problems getting into things I got bit rush headed hoping to get the job done whilst i still had assistance on site to re-fit the bumper. Lent a bit too much on the spanner and interpreted union nut going out of shape as things starting to move. Net result A/F dimensions each way were both different and tapered. It also rubbed on the pipe! Comments of the "Oh dearie, dearie me!" type. Heavily supercharged in full afterburner mode.
Fortunately warming things up with a propane torch loosened the union up enough to get things moving. One whitworth, one A/F, one normal length metric, one stubby metric (unearthed and unwrapped after 25 years in the white elephant drawer), my favourite small F type shifter and King Dicks version of the Americans favourite Crescent monkey wrench got it out a teeny bit of turn at a time. Maybe 30 very long minutes. Once off some scientific squeezing in the vice got it spinning free on the pipe again and the across flats dimensions within couple of thou'.
Having paid the brand name tax for a Hella OEM unit instead of "perm one from 5 lower cost" versions on E-Bay I expected the new condenser to drop straight in. Nope! Locating pin holes down the bottom were incorrectly positioned with respect to the bolt sleeves and each other. So in and out half a dozen times for file modifications before it all went in. Straight copy of the old one didn't work, that would have been too easy, and there is still a bit of residual stress where the bolts don't go into the brackets dead true but hopefully it will be fine. Hella managed to get the top fixings wrong too. Clip on thread carriers instead of the standard welded on nuts so the standard bolts are too short. Just to make a clean sweep the fan unit bolt holes didn't line up either so a bit of gentle levering was needed to get that on. At least it came with positive pressure inside and they did get the union threads right.
Full dark (and chilly) by the time I got the fans on but not fancying finishing off in the rain tomorrow I decided to have a go at putting the bumper on solo. Went straight on. Easy. Air deflector on the left went straight in and held OK with the remains of those stupid beak me to take me out push fixings. Grill went straight on too without dropping any screws. By that time I figured my resident workshop gremiln colony had bedded down in the warm for an early night.
Nope! The beast had taken up a distinct list to the drivers side during the days work. Which didn't really worry me as the air suspension has always been good as gold. Started him up to shift back to the proper parking spot, went right down to access height and stayed there. Light's flashing, compressor running but no lift. Gremlins clearly still wide awake and dancing merrily. Hopefully just an air bag displaced when I checked the front brakes on Monday, when its gets light again we'll see if the tank pumps up with the drivers door open. Horrible feeling that it may be time for a compressor and valve block overhaul. If it is who does a good kit these days?
