Does this pickup have a chain or belt? If a belt when should it be changed in the 5 cylinder engine? Thanks' Frank

Don't bother. Replace the unit.
3.0 liter
The oil pump assembly used on this engine is mounted at the front of the crankshaft. The oil pump also retains the crankshaft front oil seal.

1. Remove the accessory drive belts.
2. Remove the timing belt cover and timing belt. Refer to the timing belt removal and installation procedures in this section.
3. Remove the crankshaft sprocket.
4. Remove the oil pump mounting bolts (5), and remove oil pump assembly. Mark mounting bolts for proper installation during reassembly.

To install:

1. Clean the oil pump and engine block gasket surfaces thoroughly.
2. Position a new gasket on pump assembly and install on cylinder block. Make sure correct length bolts are in proper locations and tighten all bolts to 10 ft. lbs. (14 Nm).
3. Install the crankshaft sprocket and timing belt. Recheck engine timing marks.
4. Install the timing belt covers. For more details, refer to the timing belt cover installation procedures.
5. Install the accessory drive belts.
6. Refill the crankcase and start the engine.
7. Check for correct engine oil pressure and for any oil leakage.

3.3 and 3.8 liter engines

1. Disconnect the negative battery cable. Remove the dipstick.
2. Raise the vehicle and support safely. Drain the oil and remove the oil pan.
3. Remove the oil pickup.
4. Remove the chain case cover.
5. Disassemble the oil pump as required.

To install:

1. Assemble the pump. Tighten the cover screws to 10 ft. lbs. (14 Nm).
2. Prime the oil pump by filling the rotor cavity with fresh oil and turning the rotors until oil comes out the pressure port. Repeat a few times until no air bubbles are present.
3. Install the chain case cover.
4. Clean out the oil pickup or replace as required. Replace the oil pickup O-ring and install the pickup to the pump.
5. Install the oil pan.
6. Install the dipstick. Fill the engine with the proper amount of oil.
7. Connect the negative battery cable and check the oil pressure. Check for any oil leaks.

for the 3.3 you can rebuild, 3.0 - replace.

Your Nissan does not have an interference engine, meaning when the belt breaks it will not ruin your engine. In fact Gates hose and belts doesn't even list a timing belt for that engine which makes me think that you have a timing chain instead. Timing chains seldom break so unless your having some issue that make you think it needs replacing I would just drive it.

Hello placecraft
Only one 4 cylinder engine is listed for the 87 nissan pickup, a 2.4L and
this engine has a chain not a belt, and it's not an interference engine.
Hope this helps.

It has a timing belt. Recommended to be replace every 105,000 miles, timing belt also run's your water pump good idea to also replace, your engine is also an INTERFERENCE ENGINE which will damage your cylinder head valve's if timing belt goes bad. Hope this was very helpful.

the squeel is most likely the pulleys are contaminated with old rubber from the old belts or that you have a dry alternator bearing,if you try running the engine without the belt you will locate the problem easier.
the timing belt should be changed every 60k or 5 years whichever soonest...

Most definetly yes. It should run you around 500 dollars. If you timing belt breaks it will destroy your valves and head.

If it's anything like the six cylinder engines from Audi, which I'm very familiar with, and from what I remember of the V8, you have a timing belt that drives the water pump, crank, and exhaust cams, and also includes a tensioner and an idler roller. The timing chains come into play in the cylinder heads. What Audi did was to only drive the exhaust cams off of the crank, using the timing belt, and inside each cylinder head there is a timing chain assembly that is used to drive the intake cams off the exhaust cams. On a periodic service (like the timing service) you only need to do the timing belt. The timing chains are only replaced if the tensioners fail - you'll know this by a diesel-like clatter from the cylinder heads. Failure of the chain drive assemblies is very rare, which is good because they're incredibly expensive (on the V6 engines they're upwards of $700 each). If you're doing this job because it's due based on mileage, don't touch the timing chains in the cylinder heads - only change the timing belt, tensioner roller, relay arm, hydraulic tensioner, idler pulley, water pump, and serpentine belt. You can leave the chains alone.

timing chains in most cases never need be repalced for the life of the engine, timing belts on the other hand last about 60,000-100,000 miles.

how do i know when to change timing belt what are symtoms!

put new contact point in the disrabuter,
22R has chain not belt you can check if the chain is off remove cylinder head cover you can see on front side of the engine,
