I developed a fuel leak on the pump and it seems to be coming from a bolt that is facing the timing case right under the little steel line that comes from the KSB. right where the ksb line almost touches the timing case the bolt is right under it. Any ideas? does this require pump removal to fix?

 

Wow! Some one with the same problem that I thought I had!

Check the line that goes in just to the lower right of it first!

I pulled my motor based on the fact that I thought that was leaking and thought the flex plate was chipped. Both weren't the case. So even though that might look to be the prob CHECK ALL OTHER POSSIBILITIES FIRST. Don't want ya to pull everything apart if ya don't have to.

Oh I do apologize, it is the governor shaft that MIGHT me the cause.

 

read last line first
it's not a bolt
just a nut of the end of the shaft that the governor rides on
you have to pull the pump to fix it (o-ring)
remove front shaft cover
remove nut and lock washer from the pump shaft
DO NOT DROP WASHER IN THE FRONT COVER!!!!!!!!!
rotate motor until the key is located at 12:00
use puller to remove gear from the shaft
scribe the shaft end to mark the location of the key!!!!!
(this will make you a happy camper when you go to reinstall the pump)
beats the S out of knocking the key out and having it fall inside the cover???
remove injector lines
remove fuel lines (supply and overflow)
remove throttle linkage
911/2 to 93 models with automatic?
if so these will have a tps plate that mounts on the top of the pump
if you disturb the tps the transmission will have shifting problems
if so when you remove the supply line do it at the joint that is towards the fuel filter
remove the pump's rear support bolt
there are three bolts that hold the pump to the front cover
pick your poison on how to remove them
i remove the two bolts on the vacuum pump
drop it out of the way
then the bottm bolt is a walk in the park
now the pump is ready to remove and fix the fuel leak
loosen lock nut, use allen wrench to back the shaft out
only far enough to replace the o-ring
DO NOT REMOVE THE SHAFT!!!!!!!!!!!
if you do that will cause the governor assembly to fall into the pump
then you are really in the S
after you have done this the challenge might be to find the correct o-ring


ps if you are lucky and find the correct size o-ring the leak will be reaired
if not you will be just slightly PO due to the exercise you just went through
the above is not for the unskilled wrench knuckle buster
this is just for guide lines for the a leak repair
not intended to replace or modify bosch pump repair procedures!!!!!!!!!!!

 

wow, this is starting to sound like a job for the local diesel shop. i wonder how much they will charge to fix it. thanks for the info
