Is it easy to repair a Jaguar timing chain?
Firstly, Jaguars were not designed to be easy to repair? discover why the apparently simple task of checking the timing chains is far from simple. Do use 6 point sockets to start the 10mm bolts – the bolts are often in so tight the standard 12 point sockets started to slip on the heads. The preliminaries
Can a top chain tensioner be replaced on a Jaguars?
You MIGHT get away with just replacing the top chain tensioner which can be replaced without excessive dismantling. Firstly, Jaguars were not designed to be easy to repair? discover why the apparently simple task of checking the timing chains is far from simple.
When did I need to replace timing chain guides?
Replacing the timing chain guides became a must when I discovered (at 118,000 miles) that the start-up rattle was there all the time at 2,000rpm. This work was carried out in December 2009 and I avoided removing the camcovers or the head.
When did Mercedes switch to Sintered steel timing chain?
Autobild reports that the M272 V6 and M273 V8 engines used a sintered steel timing chain gear made of various materials starting in 2004, but switched to conventional steel in 2006, eliminating the problem with gear wear. The problem: nobody seems to know how many vehicles built between 2004 and 2006 are affected.
Where is the timing chain located on a Jaguar?
Assemble the VVT unit, the exhaust camshaft sprocket and the secondary chain. Then, position the assembly to the camshaft. Make sure to place the chain correctly over the tensioner. Next, place the VVT unit into the intake and the sprocket inside the camshaft.
How are gears connected to the timing chain?
Locate marks on your crankshaft and camshaft gears. These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly.
Where is the chain tensioner on a Jaguar?
Lodge the chain tensioning tool to the exhaust camshaft sprocket. Then, place the chain on the crankshaft and the VVT unit sprockets. Make sure there is no space on the drive side of the chain for any movement. Also, ensure the VVT is not turned on the camshaft. Next, install the primary chain tensioner blade and position the tensioner assembly.
What causes the chain to bind on a Jaguar?
Turn the crankshaft in a clockwise direction until the triangular arrow indent on the drive plate is exposed through the access hole. Additionally, avoid spinning the crankshaft in the opposite direction. This causes the chain to bind leading to an engine damage.
