Thank you for this information. I have the technical manual, but it doesn't appear to tackle things like the plate and bolt found at the deere site. It does tackle the pivot bolt.
So the idea isn't that the bolts are not turned to their proper location (snug, I presume, up against the plate), but that the plate itself is worn (which is visible) and if it is replaced, the bolt head would be in the proper place.
You can find this information by going to the John Deere Parts web site and doing a model lookup, putting in the 318 model number. Looking under the various sections involved.
You need to get a repair kit for the steering. The nuts and bolts there are 24M
These are plates and bolt into place : AM101198 > M88755 $11.14 each; plus bolts/nuts Metric (4) Nuts 14M7273 1.05 each; Bolts 19M7163 $0.54 each
Also check the axle pivot bolt/bushings/spacers, also check axle to see if the hole is wallowed out, if it is then axle needs to be replaced or repaired (drilled out/sleeved).
Bushings P1076H (2) $6.06; Spacers M80030 (2) $5.34; Bolt M85458 (1) $22.17
Front Wheel Spindle Bushings are serial number dependent:
S/N 222001-372595 - M83541 (4) $5.45 each
S/N 372596-999000 - M70808 (4) $6.59 each -this would be mine.
S/N 010001-______ - M70808 (4) $6.59 each
Front wheels should be set in the same holes, There should be be a sticker showing the height spacing according to the holes, Do you have that sticker? Back wheels are the same way, but should be offset by it being higher by 1/4" -I have the sticker and attempted to level, with difference between front and back, but the right hand front wheel I could not get to level with the front left. It continued to stay on the ground unless I changed the position of the height adjustment (as in the photos). After messing around for quite some time, it appeared something was wrong I couldn't see. I'll go back to it and mes with the mule drive arms -and if I read you right, place the threaded hanger on the right side to help out with the powerflo (which I do use during leaf season).
Check Guide, looks like it have been beaten down on top, belt is to be under it, so that is correct, but that angle looks off to me. No pics in the deck manual showing it with belt under it.
I need to pick up a deck technical manual from ebay...but maybe the level issue is what is causing the belt to touch the 90 degree bracket.
The deck level hanger (left to right height adjustment) (the one that has the threaded bolt needs to be on the right side to allow for adjust the side with the power flow blower weight/balance)
The front to back level is adjusted by the nuts on the arms attached to the mule drive)[/QUOTE]
