Croydon Asphalt presented Horrod’s with the challenge of taking an old 4 Ton Oil-
The Mastic Mixer preparation:
Horrod’s started by removing the engine cover, mixer body, engine and gearbox from the existing chassis. Once this necessary task was performed, the refurbishment could begin.
4 stirrers and stirrer caps were removed, the U/Pan was cleaned and a small section replaced to put the pan back to a useable condition – the existing stirrers were cleaned and built up to allow for the correct pan clearance and 2 loading lids were replaced.

The outer case, 2.5 mm mild steel sheet was removed along with the lagging – new 3 mm outer case sheets and lagging were fitted to the offside and nearside of the machine body.
The next challenge was to compact the front end of the machine since its road towable length was 5½ metres, with the new vehicle only providing 5 metres total length, the engine, engine extension shaft and jockey pulley assembly were moved which allowed us to shorten to the exact length required.

The engine and gearbox were checked and run to ensure working order was maintained.
