HappiJac 4220 & 4820 Camper Jack Parts Diagrams and OEM References

Use the HappiJac 4220 and 4820 camper-jack component reference to identify the factory-labelled jack legs, motor heads, wireless controls, mounting brackets and hand-crank tools. Lippert's current illustrated component sheet provides callouts A–U; the matching reference numbers below link directly to NewRVParts products only when the exact manufacturer number was confirmed.

Model and electrical identification: A 4220 Acme jack is not the same as a 4820 heavy-duty Acme jack. Identify the physical jack label, colour, bracket configuration and whether the installed drive uses clutchless current sensing (CCS) before choosing parts. Never assume a remote or controller fits based on appearance alone.

Official illustrated manufacturer diagram

Lippert's original component sheet uses factory callouts A–U and shows actual photographs of the controller, wireless remote, motors, 4220/4820 jack assemblies, mounting brackets, cranks and accessories. Its three numbered pages are displayed directly below, rather than requiring customers to leave the guide. The manufacturer describes this as a component photograph chart, not a jack's internal-gear exploded view.

Manufacturer page 1: controller and remote photographs, parts A–F. Check the specific control generation; an older controller photograph is not evidence that it works with a newer CCS motor. Open factory page 1 full size.

Manufacturer page 2: electric drive, 4220 versus 4820 jack bodies and brackets, parts G–O. The 4220 is a 2,200-lb model and 4820 a 2,800-lb model; do not interchange based on matching paint or bracket appearance. Open factory page 2 full size.

Manufacturer page 3: remaining accessory and kit photographs, parts P–U. Compare each labeled MPN against the exact NewRVParts product below; older CCS remote/controller combinations require their own compatibility verification. Open factory page 3 full size.

Numbered reference usage: The A–U letters in these three manufacturer pages refer to the original Lippert component list. They are not original jack-internal gear callouts, do not establish interchangeability between manual and electric equipment, and should not override a jack's identification label.

Controller and legacy-parts restrictions: Lippert identifies 733513 as a CCS wireless main logic board and 733540 as a board with remote. Remote 723915 is for 25A/CCS applications. Legacy remote 183070 works only with discontinued controller 139315, which Lippert identifies as replaced by controller/remote kit 733540. These items are not universal substitutes.
