The chunk of tranny can be used to time an engine thats out of the vehicle on a stand. It can be used on a TDI in conjunction with the glow plug "dead stop" to mark TDC on a flywheel that doesn't have a mark, or if you don't feel that the factory TDC mark is accurate. The plug is inserted in cylinder #1 and the engine is turned in one direction until it hits the plug and stops, the flywheel is marked with a scribe or marker at the timing pointer. The engine is then turned the opposite direction until it stops and the flywheel is marked again. The point midway between the marks is TDC.
,,,,,,,,,,,yes sir,,and yes jake,i have posted about this before,,,YOU GUYS USING A 210 CLUTCH ON A DIESEL,I CANT STRESS ENOUGH,THAT THE FACTORY "0" TIMING MARK ON THE FLYWHEEL IS NOT ,I REPEAT,IS NOT IN THE CORRECT PLACE,IT HAS TO BE CHECKED AND CHANGED.......you will be screwed if you do not remark the 0 mark,and go to change a timing belt down the road,the existing mark is no good, the mark is approx 1/2 inch off,at least,,and i figured the idi guys can use a tdc stop of another type,,remove the cam,and hold one of the number one cylinder valves as a piston stop,a fixture could be put in the #1 and #2 cam caps,and compresses a valve,,,,using this as a "stop".the top of this post/"quote" is right on point,,thumbs up guys!!!!and jake ,those homemade tools you have are cool !!!!!lets see some more fabbed up tools !!!!illhave to post my personal favorite,next tool,,,and this can save you alot of money after suspension work!! :idea: ilike creating something with my own hands
