Scott,
2 weeks mechanical & 1 week paint
On average it takes me 14days to test, list all mechnical problems; order parts perform all related repairs (almost always clustch disk /PP/ t-o bearing and breaks).
As I try and buy all 4X4s, we dis-assemble, inspect, Mic' all shafts, gears, spacers and replace axle and knuckle seals and run drive shaft on comparitor for trueness. And then re assemble the skeleton tractor and run/test again.....you know like a cheap rental car.....Man we put it thru the paces, bring it back into the shop, park it on a nice clean floor and leave it there for 24 hours (to look for any leaks).
All steering linkage, pitman arm, box, shaft, hyd lines, brake, clutch pedal assembly and sheetmetal is media blasted and/or chemically stripped and acid washed. Etch primmed and painted with catylized oil or acrylic enamel. Transfers (decals) applied, tractor assembled and gently tested.
My own personal tractor took me 3 days to wash, sand, mask and paint......I have a very expensive Sata paint gun, but almost alway use one of my cheap (79.00) Porter Cable HVLP gravity feet guns ( Home Depot/Lowes )
Sorry, I tried to give you the condenced story. But if it's your tractor (I mean you Know it from headlights to liftarms) it takes about 3 days to clean, prime, blocksand, and paint, and the related chemicals, tape, paper etc. run approx $300.
Regards, Mark
