Message: <blockquote data-quote="ard" data-source="post: 56573" data-attributes="member: 7237">Hi, no post for a long time but i have made some progress. After ordering the new seal kit for the tilt cylinder, i decided to make it look a little bit better than before, this is how it looked like (i have not made photos before started to dismount)<img src="http://ardiehl.de/Bobcat/photos/IMG_1381.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1382.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />There was "a little bit" dirt in the machine, it was a mix of sand, oil, glas, screws, stones, ...<img src="http://ardiehl.de/Bobcat/photos/IMG_1383.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1386.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1387.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1390.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1391.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1392.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />Than i found that selenoid<img src="http://ardiehl.de/Bobcat/photos/IMG_1393.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />using the electic and hydraulic schematics i found it is the bucket position valve and has no idea what the selenoid is used for. Later i bought a parts manual and saw there is an optional on/off kit. The switch was broken and the +12V was not connected at all. The coil was ok so mounted a new switch, connected +12V and it works.Repainted the cab<img src="http://ardiehl.de/Bobcat/photos/IMG_1395.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />and the lift arms<img src="http://ardiehl.de/Bobcat/photos/IMG_1398.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1399.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1410.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />as well as the main frame<img src="http://ardiehl.de/Bobcat/photos/IMG_1405.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1406.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />mounted new tires and took it out to respray it<img src="http://ardiehl.de/Bobcat/photos/IMG_1413.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1414.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1415.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />found out there was not enougth oil in the vent gearcase, took it out, dismounted it, checked it, filled new oil in, mounted it again.and spraying it<img src="http://ardiehl.de/Bobcat/photos/IMG_1418.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1423.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1424.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />for the <a href="http://ardiehl.de/Bobcat/logo/" target="_blank">decals</a>, i found the bobcat logo as eps via google. I drawed the 853 logo and a friend of mine created the decals<img src="http://ardiehl.de/Bobcat/photos/IMG_1427.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1429.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />My wokshop is not high enough to mount the cab so used a tree<img src="http://ardiehl.de/Bobcat/photos/IMG_1437.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1439.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1441.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />While trying to mount the tilt cylinder with the new seal kit i found out that the piston was buckled. Took the cylinder to a local hydraulics shop and they repaired it (new piston, new head), was cheeper than the bobcat spare parts.While initially trying it out i found out that the aux hydraulic does not work. Checked selenoid coils: ok, cables: ok, connected the handle and electically it seems to work. Checked it later after assembling all and it worked. It was the switch in the handle, the right one was defect so i used the left one instead. I found the manufacturer of the switch, it is avaiable from mouser for about 9$ but they want to have 50 bucks (+tax +vat) for sending to germany so i left the switch out. Used a standard switch for horn on the left handle with the original wipe and and an additional spring, works fine.Found a part that is not in the schematics, what is that ? May be a diode to protect the switches when powering off the coil ?<img src="http://ardiehl.de/Bobcat/photos/IMG_1436.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />In the meantime i wanted to start the bobcat but i had already mounted the harness in the cab. Have not found the manufacturer of the plugs (was not AMP, may be Delphi) so i build my own remote starter:<img src="http://ardiehl.de/Bobcat/photos/IMG_1474.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1474.JPG>The boss display was hard to read, dismounted it, there was dirt inside. Cleaned the lens with a dremel and some polish for mobile displays and now it's much better. However, even hard to read with bright sunlight. May be i will mount a led instead the bulb later.<IMG border=0 width=1024 src=" alt="" class="fr-fic fr-dii fr-draggable " style="" />And all mounted<img src="http://ardiehl.de/Bobcat/photos/IMG_1455.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="http://ardiehl.de/Bobcat/photos/IMG_1472.JPG" alt="" class="fr-fic fr-dii fr-draggable " style="" />The loader works well, however, there are oil leaks somewhere. Today i cleaned the remaining dirt inside the loader using a power washer, will try to find the leaks next week but it seems to be i have to pull the engine. May be the hydrostatic control block or the punps connected to it.</blockquote>
