Chassis Documentation
| Status | VIN, GVWR, and wheelbase confirmed and cross-checked. Trans and axle codes pending chart decode. |
VIN
1FDXB70K4JVA01204
Decode:
| Position | Value | Meaning |
|---|---|---|
| 1FD | USA / Ford / incomplete vehicle (chassis cab) | |
| X | Restraint / GVWR class code | |
| B70 | Chassis series — medium-duty | |
| K | Engine code — 429 | |
| 4 | Check digit | |
| J | Model year — 1988 | |
| V | Assembly plant — Kentucky Truck Plant (Louisville) | |
| A01204 | Sequential production number |
Title and insurance must read 1988 and match the VIN exactly. The incomplete-vehicle build date is October 1987; the body is March 1988. Title as an 88.
GVWR and weights
| Field | Value |
|---|---|
| GVWR | 28,000 lb |
| GAWR front | 9,000 lb — 265/75R22.5, 22.5x7.5 rims, 120 psi cold, single |
| GAWR rear | 19,220 lb — 265/75R22.5, 22.5x7.5 rims, 110 psi cold, dual |
Front and rear GAWR sum to 28,220 lb; GVWR is set 220 lb below the axle sum. Rear axle is a heavy full-floating medium-duty unit — good margin for the blower plan.
Check: confirm current tires are rated for 120 psi cold front. A lower load-range tire makes the label pressure wrong and over-tires the steer axle.
Buck tag
Firewall-mounted, adjacent to VIN and DSO tag. Ford format ("Vehicle manufactured by Ford Motor Company, Made in USA").
| Field | Value |
|---|---|
| Wheelbase | 275 (275 in)
|
| Type-GVW | B70280 (B70 series, 280 = 28,000 lb class)
|
| Body | 7
|
| Trans | AA — pending decode
|
| Axle | 2MN — pending decode
|
| DSO | blank — DSO on separate tag |
VIN on buck tag matches jamb label exactly. Verified character for character.
Fleet special-order options
- Built-in traction sanders (hopper and dispenser — photograph mounting and frame attachment)
- Front tow hooks (factory option on B-series; photograph brackets)
Both point to a municipal or district fleet order, consistent with factory LPG.
Open items
AAtrans code — must resolve before the shop quotes. Build assumes C6; do not let a quote rest on that assumption.2MNaxle code — ratio drives cruise rpm at 28,000 lb and blower gearing. Check for a ratio tag on a differential cover bolt or the housing.- Both resolve via the Marti deluxe report.
