What rollers and idlers fit the JOHN DEERE 450H?

Expert Answer

For the JOHN DEERE 450H, VANROCK supplies an idler, a track roller, and a carrier roller, along with the related track bolts and nuts, track chain, track group, track shoes, and segment group. As an independent manufacturer, VANROCK is not affiliated with John Deere.

Verified VANROCK parts for this model are: Idler (type 1) VRTP1545H4, 105.00 Kg; Track roller (1 flange) VRTA1545B0, 27.00 Kg; Carrier roller VRTC010300, 16.50 Kg. If you are replacing undercarriage parts, check whether the machine needs the front idler, carrier roller, or track roller position specifically, because wear patterns and fitment can differ by location. Also confirm the machine serial number and compare the old part dimensions and mounting points before ordering.

If you are rebuilding more than one wear item at the same time, it is often best to inspect the full undercarriage together: roller condition, idler wear, track chain elongation, shoe condition, and sprocket/segment wear. Exact fitment is confirmed through VANROCK’s dealer network, and pricing is quoted on request.
