Bolens 5118HS, 5120H Common Problems This Manual Covers
Bolens 5118HS hydraulic lift cylinder leaking and can't find the right seal or cylinder part numbers
Check the Cylinder Assembly exploded view on page 9, which covers 5118HS serial numbers only. Match your cylinder against the numbered callouts, write down each part number for the seals and end hardware, and verify your serial number range before ordering. NOS cylinder seals rarely come back once a seller opens the package, so order once, correctly.
Manual Section: Cylinder Assembly p. 9Eaton hydrostatic transmission whines and slips, need internal part numbers for a rebuild
Check the Eaton Model II breakdown on page 19 before pulling the unit apart. Match each worn piece against the exploded view callouts and record the part numbers as you go. Note your serial number too, since the breakdown covers both 5118HS and 5120H ranges and swap-meet sellers will ask for it.
Manual Section: Eaton Model Ii Breakdown p. 19Tractor won't crank, need to identify the correct interlock switch and wiring harness parts
Check the wiring diagram on page 15 first; it shows the color codes and a rear view of the switches so you can identify which interlock or starter switch you actually have. Then match that switch and its harness connectors against the Electrical Components list on page 17 before ordering anything.
Manual Section: Wiring Diagram p. 15Brake pedal feels sloppy, can't match the worn linkage hardware to part numbers
Check the Hydrostatic and Brake Linkage exploded view on page 5 and match your worn pins and rods by callout number. Note the 1/2-13 hex nut, part 1110110, listed on page 6 with a torque spec of 24 Ft. Lbs.; mark that for reassembly so the pedal stays tight.
Manual Section: Hydrostatic and Brake Linkage Assembly p. 5Hydraulic lines and valve fittings look different between models, unsure which parts diagram applies
Verify your model number on the frame before ordering any hydraulic lines or valve connections. Check the 5118HS hydraulic schematic on page 21 for that tractor, or the 5120H hydraulic system layout on page 22. The two models route their lines differently, so never mix part numbers between those pages.
