I would like to adjust my pump timing, and I have a dial indicator so that I can measure actual pump lift in this video it shows how to do this between about 4:30 and 5:30




two questions


1) what mount is he using there on that dial indicator, I only have a magnet style like what is used for doing rear ends and such
2) if I had the proper mount, what is ideal lift for bosch 190's, or is it something id have to toy with




if its something to toy with, may as well give her an 1/8th and be done with it.

 

I just went through this sticky...

(Type a title for your page here)

and it says the adapter is Volkswagon special tool 2066


I may be onto something/answered my question #1 (partially)

 

I made the tool with a drill press:

1. Drilled a 12mm hole in a wood block (1.5")
2. Put an m12 x 35 cap screw in the hole.
3. Used the hole to guide a centering punch.
4. Put the bolt through a piece of scrap 1/8" steel.
5. Used the jig to drill a 6mm hole through the bolt.
7. Sawed the head off the bolt.
8. Drilled a 12mm tap hole through a 3/4" x 1" piece of aluminum round stock.
9. Drilled a clearance for the indicator half way though said stock.
10. Threaded the other end 12mm
11. Cross drilled and threaded a 6-32 hole for a lock screw.
12. Put the drilled stud into the round stock with a drop of loc-tite.
13. Installed a 6-32 thumb screw.

 

nice. is there a good ballpark number to set the timing to?

 

Stock is 1.25mm at TDC.

 

I see that on my timing case there

 

If you PM me with your e-mail address, I can send you the couple pages of the FSM that cover pump timing.

 

i just remembered I have an FSM now haha. ill look there for details, thanks
