[Vwdiesel] How to loosen the bottom injection pump bolt?

[fudny at aol.com]

 GOT IT, thank you.

I have an old pump and counted the four mounting bolts. After your explanation I got a mirror and peeked in there and saw it is actually a stud on a flat wrap around strap. The previous owner did not reinstall it correctly and missed the bolt that it should have been held on with. 

I must fess up - I have had pumps off in the past but I just never remembered the way it is mounted. I have driven two 2 Dr. Jetta Diesel coupes  over a million miles. VWOA even sent me some frameable documents and a key chain years ago. And a Rabbit to 278,000 miles that got wrecked.

It is hot and working in a gravel driveway got the best of me, I panicked and called for help here and in minutes problem resolved.

Thank you

This is on my Grumman Kubvan and on a long trip this weekend it really smoked up the hills. Adjusted the valves yesterday and will check the IP timing today.

The  engine is a 1.6 NA diesel from a 84 caddy.





I just don't seem to be  able to get anything on the bottom mounting bolt 

of my Bosch injection  pump.



I removed the small bracket supporting the alternator bracket and  timing 

belt cover, tried every 13mm I have, swivel 13mm and the 90 degree 13mm  tool 

to no avail. 



Any tricks I should try? I don't want to remove the  alternator and mount 

if I don't have to.



Thanks -  Terry









Bottom back bolt is just weasel in there.  Bottom front bolt,  you use a 

socket from the 

front of the engine.  When the engine's on TDC, the opening in the  

sprocket lines up to 

easily put a socket and extension through and loosen it.  From '81 on,  

they use a bound 

lower bolt (the washer for one of the other two is a strap, welded, or  

such, to the bottom 

one) so you can use a socket.  '80 and earlier you need the "special"  

curved 13mm or an 

assortment of wrenches and work it out a bit at a time.
