Question about 1994 Volkswagen Passat
VW 1.9 liter turbo diesel engine code AAZ is out of vehicle. Cam shaft and injection pump are at top dead center, the mark on the pressure plate is not. To proceed do I lock the camshaft and injection pump, remove the timing belt and adjust the crankshaft to top dead center, then replace the timing belt? Also, the crankshaft pulley doesn't seem to want to come off (and will need to to get the lower timing belt cover off to get the timing belt off) does this require a special puller tool or will a generic puller work or do I just need to give it some muscle after the pulley retaining bolts are removed? Detailed instruction would be helpful. Thanks.
From what I remember of manuals, usually a crankshaft pulley requires a special puller to prevent damage to said pully. usually, a second specialty tool is also required to reinstall it. be very carefull with a proceedure like this, as one minor misalignment may destroy the engine.
one of the best places to look for both detailed instructions and specialty tool numbers is a Chilton manual. these are sometimes available in a local library for access. make sure, with this kind of repair, that you follow instructions to the letter. also, have a pro doublecheck your work.
