Perkins 6.354

The Perkins 6.354 is a 5.8-litre six-cylinder direct-injection diesel from Peterborough, England (354 cubic inches), built from 1960 until 1996 for trucks, tractors, industry and boats; more than a million were made in Peterborough alone, plus licence builds in other countries. For boats Perkins built it naturally aspirated (6.354) and turbocharged (T6.354, HT6.354), also in inclined versions that fit below a cockpit, and from the late 1970s as the redesigned 6.3544 and T6.3544, whose new block and cylinder head often take different gaskets, pumps and thermostats. Since 1974 the engine number starts with a family code (TC = 6.354, TE = T6.354, TW = 6.3544, TU = T6.3544 …), and the notes below say which versions Perkins lists a part for. From the mid-1980s Perkins replaced the family with the 1000 Series (Phaser), a different engine; some boats also have 6.354s marinised by other firms, whose cooling and exhaust parts may differ from the factory parts listed here.

Manuals & documents

Perkins no longer offers the 6.354 manuals as downloads: its 6.354 Series page points to the operation and maintenance manuals, which come on paper through Perkins distributors, and once you register your engine, My Engine shows parts books and service literature. The 1970 workshop manual cited on this page (publication 601 SER 1020) is named without a link. The other links go to Perkins’ engine-number guides and Jabsco’s impeller table. We host no manuals.

Perkins lists it across the family, including the T6.3544 and HT6.3544. Dealers sell this size and the 57 mm one for factory-marine 6.354s, so measure the old impeller before ordering.
Pump cover gasket049078510,11,12,13—Paper gasket under the six-screw end cover of the sea-water pump, 76 mm outside diameter. Perkins lists it for the same engines as impeller 0460038.
Pump seal kit2488017614—Impeller shaft seal of the gear-driven sea-water pump; Perkins lists it for the 6.354, T6.354, H6.354, HT6.354 and 6.3544. Only Perkins’ own catalogue confirms the number.
Raw water pump248832415,16—Perkins’ own number for the gear-driven sea-water pump; Perkins lists it for the 6.354, T6.354, H6.354, HT6.354 and 6.3544, and a dealer sells it as the 6.354 sea-water pump. Perkins does not say which Jabsco model it matches, so compare the ports with your old pump.
Raw water pump9990-4117,18,5—Jabsco number of the clamp-mounted bronze pump with 3/4 in NPT threaded ports, fitted as standard to the 6.354 (TC), H6.354 (TD), T6.354 (TE), HT6.354 (TF) and 6.3544 (TW) according to a dealer. The T6.3544 (TU) and HT6.3544 (TZ) have a flange-mounted pump instead.
Engine oil filter265440319,20,18,21,22—Spin-on filter, 96 mm diameter, about 130 mm high, 3/4-16 UNF thread; Perkins lists it for the 6.354, 6.3544, T6.3544 and C6.3544. Two filter heights are used on 6.354 engines, so measure the old one. Early engines with a paper element in a steel bowl can be converted with a spin-on filter head that dealers sell.
Engine oil filter265440723,24,25—Longer spin-on filter, 96 mm diameter, 171 mm high, same 3/4-16 UNF thread; Perkins lists it for the whole 6.354 family, including the T6.354, HT6.354 and T6.3544.
Fuel filter (engine)432665827,18replaces 26561117Delphi HDF29626Element for the CAV/Delphi-type filter head: 88 mm diameter, 20 mm bore, 70 mm high, with sealing rings. Two dealers list it for the 6.354 and T6.354, one under the old number 26561117.

The alternator belt length depends on alternator and pulleys: dealers stock 13 mm belts of 1275, 1300 and 1475 mm for the 6.354, so compare with the old belt.
Cold-start aid (Thermostart)266610353,54,55—Intake heater (Thermostart) in the inlet manifold; Perkins lists it for most of the family, including the 6.354, T6.354, HT6.354, 6.3544 and T6.3544. Dealers sell it with spade or screw terminal; on marine engines it sits in an insulating sleeve (see tips).
Injector nozzle264667256,57,58—Delphi (CAV) nozzle BDLL150S6329, six per engine; Perkins lists it for the 6.354, 6.3541 and 6.3544. Other nozzles were fitted depending on rating (the 1970 manual lists several types), so read the number on your old nozzle first, and renew the copper sealing washers.
Pressure switch284806259,60—Oil-pressure switch for the warning light or alarm, not a gauge sender: single spade terminal, tapered thread, earths through the block. Perkins lists it for the 6.354, 6.3541, 6.3544, T6.3544 and others; engines with insulated electrics need a two-terminal switch (see tips).
Oil filler plug248784561,62,63—Oil filler cap; Perkins lists it for most of the 6.354 family. Dealers sell two cap sizes for the 6.354 (about 45 and 62 mm), so measure the old one.
Pressure cap2487B40164—Pressure cap for the combined header tank and heat exchanger at the front of the engine. A dealer sells caps as equivalents to 2487B401 in three shapes (60 mm winged with short or long reach, 70 mm round). One dealer source only.

Service intervals

TaskInterval
First serviceAfter the first 25–50 h (Perkins’ post-delivery check): change oil and filter, check the cylinder-head nut torque, set the valve clearance (0.25 mm hot), check coolant, leaks, belt tension, mountings and idle speed58
Oil level checkDaily: coolant level, sump oil level and oil pressure (Perkins); dealer guideline: oil level before every use58,83
Engine oil changeEvery 200 h or 4 months, whichever comes first (1970 workshop manual); Perkins’ current guidance is every 250 h. Dealer guideline for boats: every 50 h, or at the start and in the middle of each season58,84,83
Oil filterWith every oil change58
Fuel filterFinal filter element every 400 h or 12 months on agricultural and industrial engines, every 800 h on vehicles (1970 workshop manual); Perkins’ current guidance is every 500 h or yearly. Dealer guideline for boats: with every oil change58,84,83
Fuel pre-filterClean the water trap every 200 h or 4 months; clean the lift pump’s gauze strainer every 400 h or 12 months58
Air filterClean the oil-bath air cleaner or empty the dust bowl every 200 h or 4 months, more often in dust (1970 workshop manual); Perkins today: inspect and replace as needed58,84
Belt tension checkEvery 200 h or 4 months58
Hoses & clampsCheck hoses and clips every 400 h or 12 months; check the engine for oil and water leaks every 200 h or 4 months58

InjectorsHave the injectors serviced every 2400 h58
Valve clearanceCheck and adjust every 2400 h: 0.25 mm (0.010 in) hot, inlet and exhaust58
AnodeHeat exchanger anodes: check regularly, replace before half the zinc is gone (dealer guideline)83
Storage / winterisingBefore a lay-up of several months (Perkins): drain the warm oil, renew the filter and refill; run the engine for 15 minutes on a preservation oil in the fuel system; drain the cooling water; spray a little oil into the cylinders; oil the rocker gear; seal the air intake and exhaust; take the battery off and recharge it monthly58

Perkins publishes no operation manual for the 6.354 online. The schedule comes from Perkins’ 1970 workshop manual (publication 601 SER 1020), which was written for vehicle, agricultural and industrial engines, and from the current guidance on Perkins’ 6.354 Series parts page (oil every 250 h, fuel filters every 500 h). The shorter intervals for boats, the check before every start and the anode advice are dealer guidelines from Foley Engines, a Perkins dealer (Tech Tip 36). Oil and coolant capacities are left out on purpose: the manual gives the sump capacity only for vehicle engines and marine sumps differ, so fill to the dipstick mark.

Perkins dealer Foley Engines gives 100 lbf ft for the Perkins 6.354 cylinder head and 115 lbf ft for the 1/2 in head bolts of the Perkins 6.3544, so check the manual for your engine number58,86
Oil pressure30–60 psi (2.1–4.2 kgf/cm², about 2–4 bar) at maximum engine speed and normal operating temperature58
CoolingFactory marine engines: fresh-water circuit with Serck heat exchanger, belt-driven coolant pump and gear-driven Jabsco 9990-41 sea-water pump with 3/4 in NPT ports; the T6.3544 (TU) and HT6.3544 (TZ) have a flange-mounted sea-water pump. Depending on the build, the heat exchanger is combined with the header tank at the front, mounted on the side next to a separate oil cooler (later Lowline engines) or, on the Perkins 6.3544 (TW), combined with the exhaust manifold (dealer information)17,87,88,64
Thermostat opens at1970 workshop manual: opens at 75–80 °C, fully open at 87–90 °C. Dealer figures for marine engines: early 70 mm thermostat (codes TC, TE, TJ) opens at 78 °C, later 54 mm thermostat (codes TG to TX) at 82 °C58,89,40
StartingCAV Thermostart in the inlet manifold, fed with fuel from a small reservoir; 12 or 24 V, 15 A at 12 V58
AlternatorCAV or Lucas AC5 (55 A at 13.5 V) or 11AC (43 A); some engines have a Lucas C40L dynamo (25 A). Starter motor Lucas or CAV M45G or CA4558
Engine number locationPlate at position D in Perkins’ engine-number guide; on early engines the number is stamped on the side of the auxiliary drive housing. Old numbers look like 354U251 (354 = cubic inches, U = built in the UK); from 1974 the number starts with the family code (e.g. TC), followed by the parts list number, country code, serial number and year letter90,58,91
VersionsFamily codes (engine numbers from 1974): TC = Perkins 6.354, TD = H6.354, TE = T6.354, TF = HT6.354, TG = Perkins 6.3541, TH = T6.3541, TJ = Perkins 6.3542, TK = C6.3542, TP = T6.3543, TR = Perkins 6.372, TT = TC6.3541, TU = T6.3544, TV = Perkins 6.3724, TW = Perkins 6.3544, TX = C6.3544, TY = H6.3544, TZ = HT6.354491
Years built1960 to 1996; more than a million in Peterborough, plus licence production in Mexico, Argentina, Turkey, Peru, South Africa, Brazil and the USA85,84
SuccessorPerkins 1000 Series (Phaser), which took over from the mid-1980s85
GearboxNot part of the engine. A Perkins dealer’s checklist for boats with a Perkins 6.354 names Borg Warner Velvet Drive gearboxes with 71 or 72 series reduction gears; make and ratio are on the gearbox plate92

Good to know

  • Read the full engine number before ordering. Since 1974 it starts with the family code: TC for the 6.354, TE for the T6.354, TD and TF for the H6.354 and HT6.354, TW for the 6.3544 and TU for the T6.3544. Older engines carry numbers like 354U251, stamped on the side of the auxiliary drive housing. Perkins lists many parts in several versions for the same engine type, so dealers ask for the full number.91,58,90
  • The 6.3544 and T6.3544 of the late 1970s have a redesigned block and cylinder head, so their gasket sets, head gasket and coolant pumps differ from those of the earlier 6.354 and T6.354. Across the family, dealers also sell two thermostat sizes (70 mm on early builds, 54 mm on later ones), two oil-filter heights, two lift pumps (two- or four-bolt flange) and two rear crankshaft seals (rope or lip type): compare with the old part before ordering.85,89,40,20,18,93,58
  • The brass end cover of the Jabsco sea-water pump wears, so the impeller no longer seals: flow drops and the impeller blades fail early. If a new impeller does not bring the flow back, replace the end cover as well; dealers sell cover kits for the Jabsco 9990-41. Carry a spare impeller and cover gasket on board.13,9
  • Factory-marine 6.354s often have insulated-return electrics, so the engine block is not used as earth. The Thermostart then sits in an insulating sleeve in the inlet manifold, and the common single-spade oil-pressure switch 2848062, which earths through the block, does not work: these engines need the two-terminal type.94,60
  • Oil weeping from the rocker cover is a known 6.354 problem: according to a dealer, the original cork gasket hardens from the heat of the exhaust manifold beneath it and then leaks. Nitrile rubber gaskets last longer.95,96
  • Many Perkins heat exchangers left the factory without zinc anodes. Fitting them on the sea-water and coolant sides and changing them before half the zinc is gone keeps broken-off pieces from blocking the tube stack.83
