What idlers fit the Caterpillar D4H LGP, and what VANROCK options are available?

Expert Answer

For the CATERPILLAR D4H LGP, VANROCK supplies an Idler (type 1) under part code VRTP0104P0, weight 82.50 kg. VANROCK also supplies related undercarriage parts for this model, including track rollers, carrier rollers, sprockets, track chains, and track shoes. VANROCK is an independent manufacturer and is not affiliated with Caterpillar.

If you are confirming fitment, the key checks are the machine variant, idler type, and the condition of the mating undercarriage parts. A worn idler often shows uneven wear at the rim, seal damage, noise, or track guidance issues, but the idler should always be matched with the exact machine application before ordering. If you are rebuilding the undercarriage, it is also smart to inspect the track chain, rollers, and sprocket teeth at the same time, because mismatched wear can shorten the life of a new idler. VANROCK sells through an appointed dealer network and quotes pricing on request after fitment is confirmed.
