Intro

The 232/03407 bucket ram seal kit is the aftermarket rebuild set for the bucket cylinder of JCB mini excavators — documented by UK JCB parts specialists and parts catalogs for the JCB 802-7 plus, 803, 803 plus, 803 Super and 804 plus. It is a 50 mm rod × 75 mm bore application (per Sagroparts catalog data). Rebuilding the bucket cylinder with this kit restores curl force and stops the bucket from creeping when the machine is parked or under load.

Verified Application

Fitment verified against Chris Beard APS (UK JCB parts specialist), Sagroparts and multiple eBay parts listings:

• JCB 802-7 plus — bucket cylinder
• JCB 803 / 803 plus / 803 Super — bucket cylinder
• JCB 804 plus — bucket cylinder

Fitment note: some product pages describe this kit for JCB 8052 / 8060 machines. We could not verify that application against any independent source — the documented fitment is the 802-7 / 803 / 804-plus mini-excavator range, so confirm your cylinder casting before ordering.

Fitment Verification

Verify before ordering: (1) the part number on the old seal set or the bucket-ram casting; (2) the machine model (802-7 plus / 803 / 803 plus / 803 Super / 804 plus); (3) rod and bore measurements of 50 mm and 75 mm. If your machine is an 8052 / 8060, send us a photo of the cylinder tag — we will source the correct kit reference for you before dispatch.
