Working on a Massey Ferguson 7618? This page holds more than 300 parts that fit, including trailer couplings, electrics and lighting.
Four wheel drive that no longer engages cleanly, a thermostat stuck open, a seal around the door handle that lets in draughts: the jobs on a Massey Ferguson 7618 vary a lot. This page lists more than 300 parts for it, from GRANIT, Scharmüller, Walterscheid, ROCKINGER and HELLA.
There are internal and external plates, including plates for the four wheel drive clutch, plus adjusting plates, PTO O-rings, sealing rings and seals. When rebuilding a plate pack, lay the old plates out in the order they came out. You will see straight away whether one was missing or fitted the wrong way round, and you can stack the new set the same way.
An inductive sensor reads transmission speed. If it throws a fault, check the tip for metal fines before replacing it. A clean is sometimes all it takes.
Thermostats for the 7618 come in more than one version. The opening temperature is stamped on the old one, and that is the value to match. A thermostat that opens too early keeps the engine running cold in spring and autumn.
For the rear there are drawbars, drawbar frames, adapter plates, automatic hitches and forced steering for trailers with a steered axle. The linkage is covered by hydraulic lift rods. Work lamps come partly from HELLA.
A hydraulic lift rod lets you adjust the lower links without leaving the seat. If oil is weeping past the rod, keep the cylinder clean and replace it before dirt gets into the hydraulic system. On forced steering, play in the lock is the first sign of wear. Check it at every service, since a trailer that no longer tracks cleanly scrubs its tyres. Adjusting plates in axle and gearbox always go back where they came from, so keep them sorted by position when you strip things down.
An automatic hitch needs little care. Keep the catch and the lock clean and lightly greased, and listen for it to latch after coupling up.
Take the serial number from the type plate and the reference number from the old part. Transmissions and equipment vary within the 7600 series, so both help. For clutch plates, measure the inner and outer diameter of an old plate before you order.
