George,
I just tested something about JDParts since I have been in error twice in two days and wanted to see what the differences were. If I go to the parts catalog without logging in I expect to not get pricing -- but find that the parts sometimes show as NLA for the not logged in search results, and available if I sign in. Is there a policy of giving preference to 'members' for parts that might be getting towards end of general availability? Guess I'll not take any shortcuts in checking things in JDParts from now on...
The price on the parts to adapt the Onan to the 317 are all REALLY spendy...as I recall the plate for the engine mount HE403-2615 was several hundred dollars also (it now shows as NLA even when I am logged in...)
The 317 Onan that I sold Brandon last year was a factory parts/dealer installed engine replacement and very nicely done using all the parts called out in the section 22 of the PC1698 -- even the foam pieces that seal the blower housing and the side covers! Guess I did not appreciate at the time what was involved in the swap, since I bought the tractor with the Onan already in it.
