What determines an engine crankshaft needs to be reused or needs grinding?
The less oil to the crank the faster it can wear out. When you reduce the size of the bearings you reduce the overall surface area too. Less surface area equals less friction and better engine performance. Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch.
Can you reuse crank bearings?
if a crankshaft shows no signs of wear and the bearing clearances fall within spec it doesn’t need to be reground. if the bearings aren’t scored or overheated, then they can be reused, but they are so cheap you might as well get new ones.
What happens if the timing belt fails on a VW Jetta?
The VW 2.0L 8V is an interference engine (a.k.a. non-clearance engine). If the VW timing belt fails, the timing belt system that links the cylinder head, camshaft, and crankshaft no longer run in sync.
What kind of engine does a VW Jetta have?
The 1.8T 20 valve engine was used in 2000-2005 VW Jetta (US) A4 Platform. The 1.8T 20 valve engine is driven by a timing belt system which links the cylinder head, camshafts, and crankshaft to run in sync.
What kind of timing belt does a VW 2.0L have?
Apart from the timing belt itself the VW 2.0L 8 valve engine’s timing belt system consists of 2 serviceable timing belt components. One is the water pump that is driven by the timing belt. Second is the timing belt tensioner which provides variable spring loaded tension to the timing belt.
Why does my VW transmission jerk when accelerating?
If you bring the number one cylinder up on its compression stroke and crankshaft set to top dead center, then take off the distributor cap to see if the distributor rotor is pointing to number one cylinder on… Hi there. The problem with your transmission is the 1 to 2 shift accumulator has either a broken spring or a split o-ring on the piston.
