Resealing the drive shaft of the Injection pump

[JasonKreke]

Has anyone tried to reseal the drive shaft part of the injection pump? I'm not exactly sure what to call that seal. I was hoping to not have to remove the pump and/reset the timing. I know its not that big of deal, but I have a lot of irons in the fire and I'm losing prime pretty bad. I have a seal kit that came with the car. I also have an older pump that came with it too. Here is the question that may frustrate some but what is the cheapest fastest way to fix that seal? I'm a father of 11 (yes all ours) and we have a pretty active homestead with a few building projects and I work full time. I can not say enough good things about these TDIs. I've owned 4 and there are just amazing. I have a new Passat 05 TDI and the transmission went out again. I replaced the engine by the recommendation of my mechanic because of the oil pump issue. So I have a 75k mile engine in a near worthless car. Thank you all for any help!!

You're correct to treat this particular repair with respect; the IP sprocket has to come off and the shaft is not indexed (with a keyway or the like), so care has to be taken to preserve the factory alignment.

You'll probably also find that the front seal is NOT included in your seal kit and has to be ordered separately.

It's not rocket science but it does require some care... best bet might be to do some Youtube searching as there's a good chance someone has posted a run-thru and you'll be able to get a feel for if you want to tackle the job or just ship the pump out.

I'm sure that Vince has just forgotten, but the IP sprocket on these VE pumps is in fact set with a key, so you can't put the sprocket on wrong.

Vince is correct though, you may not have the correct drive shaft seal via the kit, they often only include the older pump driveshaft seal in these. Ordinarily I would have one in front of me for the part number but I don't ATM. I do know that @ToddA1 has the part number, he might chime in and provide that if he sees the post.

I caution you about taking the easy way out on this, or rather the fastest way out. It is a known and documented fact that once you seal one leak then another sprouts up and another and another etc etc, on and on. Eventually you expend more time going back and doing all the individual seals than if you'd just done them all at once at the beginning and been done with it.

You will have to redo the timing to replace the shaft seal as well, which suggests that if you are anywhere close to the TB change you'd be well to do that too....

Good luck!

Good catch Steve, I was thinking the previous gen pump.

I believe the main shaft seal for this is Bosch part # 2460283001.
