When a crane repair order says “PR70 PTO,” ask what is fitted at both ends of the power take-off. The gearbox connection identifies one side of the job; the driven component and its connection identify the other. The PR70 power take-off listed for the XCMG QY25K is a useful catalog reference. A crane badge and a PTO name alone do not establish which configuration should be ordered.
Photograph the crane plate and the gearbox plate separately. Keep the full type, variant and serial details readable. If the workshop has records of a previous gearbox change, tell the supplier which unit is installed now. A parts drawing for the original machine may be a starting point, but purchasing should not assume the build has remained unchanged over the life of the crane.
Take a wide photograph showing where the original PTO sits, then a close-up of its markings. If the old unit is already removed during an approved repair, send views of the mounting face and output end. Label the views so the supplier can distinguish the two. Do not remove the component solely for a quote or try to identify the internal gear by operating the unit for a video. When the visible evidence does not identify the variant, use the applicable parts documentation and ask the supplier what else it needs.
A crane power take-off can be described by its driven equipment as well as its gearbox side. Ask the workshop to name the component connected to the output and provide its identification if available. Include a photograph of the connection or the callout on the parts drawing. If the inquiry is for a PTO without the driven unit, say which parts will remain on the machine and which are expected to arrive with the replacement.
The quote should distinguish the PTO itself from any adapter, connection hardware, sealing items or control components needed for the job. Do not infer that an item is included because it appears next to the PTO in a listing photo. If the workshop has identified a requirement for the drive arrangement, have the supplier document the proposed match. Avoid inferring rotation or other operating details from housing shape; the service team should confirm the specification before purchase.
Ask the seller to state the reference that will appear on the delivered unit. If it differs from the original, request an explanation that connects the offered PTO to the gearbox and the driven equipment, not just to the crane model. If the supplier cannot confirm one end of the match, keep that point open on the quote comparison sheet. Do not convert an unresolved alternative into an approved order simply because the other quotation takes longer.
A purchase line might read: “PR70 requested. Fitted gearbox plate, original PTO markings and output photos attached. State supplied reference and included items; flag any fitment details still unconfirmed.” Preserve that wording with the approved quote. If the order is placed for stock rather than a specific breakdown, retain the machine and gearbox reference as supporting information so the next person can check the actual application.
Compare the package label with the approved reference and inspect the visible mounting and output features against the agreed information. If a required adapter or control item is packed separately, check it against the packing list before sending the unit to the workshop. Keep any discrepancy tied to the order line and the photos. Commissioning and acceptance are service decisions, not checks that can be signed off from the sales listing.
Use that phrase to find the catalog entry, then confirm the fitted gearbox, PTO output and scope of supply. The replacement decision needs evidence from the actual machine.
Use the assembly diagram checks to place the PTO on the correct gearbox drawing. Record supplied hardware and any open compatibility question in the supplier quote comparison.
