Need the factory numbers for your Bolens DuraTrac? This 104-page Bolens GT 2000 service manual PDF (OEM #1760169) also handles the 5117H, 5118H, 5118HS, 5120H, DGT 1800, and GT 1800, so one download serves the whole family. You get full wiring diagrams with the factory wire color code, hydraulic schematics for the power lift and both spool valves, plus step-by-step hydrostatic, transaxle, and differential teardowns. Troubleshooting guides walk every system, from carburetor adjustments to PTO clutch service, in gas and diesel versions both. Check hydrostatic charge back-pressure at 120 to 160 PSI, then look for 800 PSI minimum from the charge pump with the steering wheel held at full lock. These numbers left the parts counter decades ago. Bookmarked and readable on any device; prop a tablet on the fender and get your tractor running again this season.
