Here is a tip for reviving a NON-"O" RING chain that is rusted & mud riddeled. First you need to get these items, On old pan (not mums' good one), Some high melting point grease, Some degreaser/cleaner & brush, An old container for cleaning the chain (not mums' best tupperwear) Appropriat clothing, Closed footwear,long pants, long sleaves, protective eyewear & gloves. A piece of wire to make a hook. An apropiate way to heat the pan. (not mums new Kitchen) PARENTIAL PERMISSION/SUPERVISION WERE APPLICABLEFirst clean the chain in the degreaser, using the container , soak & leave an hour or two. Then hang the chain on wire over the container until dry, Now heat the grease in the pan just until it melts, DON'T BOIL IT Using the wire, place the chain in the pan for two minuites and then (using gloves), place the pan somewhere you can hang the chain over it. Using the wire, hang the chain over the pan and wait till it cools. Now your chain is lubricated like it is straight out of the box!! Regards Andrew Porrelli
Check your owner's manual for the recommended mileage for
replacing your timing chain. Replacement for a Nissan Altima is 60,000
Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.
Drain the cooling system and disengage the negative battery
cable. Undo the spark plug wires and set the No. 1 piston at "Top Dead
Center" (TDC) of the compression stroke.
Disconnect the engine undercover, vacuum and fuel hoses,
harness and connectors, drive belts, power steering reservoir,
alternator and bracket, upper radiator hose, air duct, front exhaust
tube, intake manifold collector supports, collector and exhaust manifold
and the distributor.
Prop up the oil pan and take out the front engine mounting,
the valve cover, camshaft sprockets, cam bearing caps, camshafts,
cylinder head bolts (reverse the installation order), cam sprocket
cover, upper chain tensioner, chain guides and chain, idler sprocket
bolt, cylinder head, intake manifold and cylinder head gasket and the
steel oil pan.
Place a steel cutter between the steel and aluminum oil
pans. Slip the cutter around the oil pan's edge. Disengage the steel oil
pan, baffle plate, oil strainer and the front tube.
Secure the car on jack stands and place a seal cutter in
between the oil pan and cylinder block. Slip the cutter around the oil
Install Your Timing Chain
Reconnect the crankshaft sprocket, oil pump drive spacer,
idler sprocket and lower timing chain. Position the lower timing chain
on the sprockets and line up the mating marks.
Rub on an unbroken bead of liquid gasket and put in a new
front cover and oil seal. Secure the bolt at 105 to 112 foot pounds
(142 to 152 Nm).
Eliminate any old material from the pan and cylinder block
mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the
oil pan and cylinder block.
Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.
Refill the cooling system and add clean oil in the engine.
Hook up the negative battery cable and any other disconnected parts or items. Start the engine and look for leaks.
Tips & Warnings
Procedures for replacing timing chains in Nissan Altimas vary slightly depending on engine size.
Make sure the new timing chain matches the chain you are removing.
the lock ring is available, have seen them from your local parts houses.if the lock ring is rusted that bad make sure the metal lines for fuel pump are not bad. why are you replacing is it leaking not sure how you would no without removing tank. good idea to also replace large o'ring under lock ring(also available @ part house.
There a few things you can do. First, give your chain a good lube with some quality chain lube. DON'T use WD40, that will make things a lot worse. If your chain isn't the problem, then it could be the cables are gunked up in their housings. Mud and dirt can enter the sheath of the cable and cause them to stick. Rust can do the same thing. Try replacing the cables with new ones, and make sure to have them done by someone who knows what their doing. You don't want to lose your brakes unexpectedly, it's best to have a professional you trust change them out for you.
You can use the o-ring chain but make sure the lube you use on the chain is o-ring compatible.Some will affect the o-rings in the chain.Only way to get the chain on is to remove the rear wheel.Its not a hard job.1st time you do it,have a pen and paper handy and draw every washer,spacer and backet as you are looking at it.That way when it goes back together, you have a redy ref. to look at.Make sure you draw each shape of each piece.Draw the axle out very slowly so if anything drops,you know where it came from.Also,lay out every item in the order that it was assembled on a clean flat surface.Work slowly.Hope this helps
