Mate..........mine sounded bad a few months back and I'm glad I changed it when I did..........the gear teeth faces were all pitted and getting destroyed.
Changing to a Rollmaster chain is simple.........and a good choice of brand there. Get the Rollmaster with the 9 keyway slots.....same price, but more options for tuning if needed later.
You'll need a few tools to make it easy: Crank balancer puller, gear puller, torque wrench, gaskit scraper and a fat tube of high temp engine gaskit sealer (red stuff). You'll also need a gaskit kit after removing the timing cover and water pump.
Take off belts & water pump
Remove crank pully & harmonic balancer
Remove mechanical fuel pump if you have one
Pry off timing cover
DON'T DROP ANY BITS INTO THE SUMP!!
Refit crank bolt and rotate engine intil the two dots line up on crank and cam cogs. (ie: crank dot @ top 12 o'clock and cam dot at bottom 6 o'clock)
Slide out the dual idler gears.
Undo cam retaining bolt and remove top gear (wiggles off)
Use gear puller to remove crank sprocket.
AVOID MOVING THE CRANK/CAM WITH gears/chain off.
The new chain set will have to slide on all together. Set the sprockets so the dots line up and then slide on. You may just need to tweek the crank a "millifart" left or right using a socket on the crank bolt so the sprockets slide on. IF you need to tweek it left, the bolt may just come undone insted of moving the crank. A crank socket can help here if you can borrow/buy one.
Refit cam retaining bolt and crank balancer and these will push the chain into its seated position (mainly crank sprocket). Do them up evenly and slowly so as not to bend anything. Then pull the balancer off again to allow fitting of the timing cover.
Instead of using a new rubber front sump seal, I just clean the sump area and timing cover VERY well with parts cleaner, then fill that fat groove on the timing cover with gaskit sealer and put a fat bead along the sump and up into the cracks. Let it go a little tacky before refitting.
Personally I perfer to let it all set for 24hrs before starting it up. You'll enjoy the quiet bliss of that chain
edit: I recall having to grind bits off my gear puller arms so they could fit behind the gears and get a good bite. There's not much room behind the gears.
