A special crankshaft-holding tool is recommended for removing the hi-torque (330 ft pounds) 27 mm hex head bolt from the nose of the VW 2.5 L ACU gas engine used in the 1995 Eurovan.
The Bentley "factory" manual section for the 2.5 L 5 cylinder gas engine lists VW tool #3248 for this task. There are numerous other such crankshaft holding tools listed for VW/AUDI engines of this type, including special holding tool #T10025. On 20-11-2008 forum member "jets" provided an excellent drawing and photos of the T10025-type tool thereby skillfully crafted (http://www.vwwatercooled.org.au/f136...ter-21955.html).
In various VW special tools sites and postings, the photos, drawings and listings of these tools depict different dimensions and configurations, I would like to know if the T10025 special holding tool applies to the 1995 Eurovan with ACU (gas) engine #012750 with 27 mm crankshaft "nose" bolt.
Can anyone confirm that the VW T10025 tool will interface with and hold the crankshaft of my vehicle. Also, can someone add additional information as to which holding tools fit which Eurovan VW engines (gas vs diesel; 5 cylinder vs. 6 cylinder)? The photos and drawings of the various tools appear to show a similar slotted-ring configuration that engages the front pulley (vibration damper) but with different ring and slot dimensions and with different arm/lever configurations welded to the slotted engagement ring. Generally, the descriptions of these holding tools are relatively non-specific. Are there numerous crankshaft pulley/ bolt configurations that each require their own special holding tool or do they universally fit most/all VW engines of this type? I note at least 4 different tool configurations. One would hope that "one tool fits all."
Also, the VW EKTA parts system contains a note under the water pump section that instructs the mechanic to carefully check the casting number on the installed water pump and, if the pump gear has 20 teeth, then replace the camshaft gear with a new gear, #111d. However, the EKTA note does not instruct the mechanic to change the crankshaft gear or the timing belt (specification remains @124 teeth). Because the water pump gear interfaces with the DRIVEN or pulled-upon belt path, it appears that in the absence of a change in the number of timing belt teeth, the larger 20 tooth gear would push the cam belt outwards, to the front of the vehicle, causing a slight advancement of camshaft timing. Does anyone know why the waterpump gear specification was changed from 18 teeth to 20 teeth? Was there an issue with impeller cavitation or belt wear?
With respect to the new 111d camshaft gear I suspect it's keyway location has been altered slightly to correct cam timing. Can anyone provide information about the cam gear change?
Thanks,
Will
