Tim S said: (quoted from post at 20:56:14 06/09/13) My Brother and I bought an 8630 brand new in 1979, it was setting there as the 8640"s came out, we rolled the tach on it twice,,worked the snot out of it, and yes we did plenty of work on it too...


What are some of the main fail points? I dont plan on working the snot out of it but it will be worked steady hopefully. I am primarily no till but I have a few customers that still want their ground worked.
I know things like pins/bushings in the center, U Joints, and other things in that area are subject to wear. Are they prone to faster wear than other models?

The main goal is to have a fert rig to compliment my precision soil sampling and maybe pull a pull type sprayer through pastures. I really like the idea of having a usable tractor after spreading fert and not have a spreader truck with only one use.

I have been "well" versed with 84 & 8630's, One of the engine faults is the cam gear that drives the oil pump can fail at about 9,000 to 12,000 hours, this is why you see a lot of them advertised with a 50 series engine in them,,Deere had a good program back then to replace the complete engine, another weakness was the font end is bolted to the front of the engine block, when the tractor front end oscillates hard against the front stops it can "flex' the block,breaking the crankshaft,I have seen this happen several times on both the 84's and the 86's, the high low planetary has straight cut gearing which set up a vibration that would cause the low clutch to fail, a new complete high/low from a 40 series can be installed to correct this,, these are the main fail points. When Deere went to the 60 series they corrected all of this..
