Water pump leak

I had the engine running yesterday, first time for 30+ years.
Had a couple of water leaks, fixed with new clip and home made gasket.

I now find there is a slow drip from behind the pulley
There is a brass hollow plug wich can be removed with a screwdriver just behind the pulley

It's about one inch long and when I removed it there is what I presume to be grease, more like a solid sticky lump at the moment.

Do I fill the tube with grease, or do I need to fit a temp. grease nipple and pump some grease in tio the housing.

Also what type of grease, LM grease, or a special pump grease.

Thanks
Roger

PS can post a photo of the pump, in situ, if need be

There is presumably a Carbon Gland next to the water pump impeller which has failed. The gland is usually backed up by a coil spring to keep the gland in contact with its seat. Probably that spring has rusted until weak or broken since you say it has not been used for years. Dismantle the pump (you may need a press) and if the gland is ok it should be simple to replace the spring.

You don't say what vehicle it is, but 30 years ago it was usual to buy a kit of parts for the job, exchange not being an option. Whether you would find a kit now though I don't know. The last one I stripped (off a 1.5 BMC diesel) about 4 years ago needed a new (tube) bearing. My local bearing man found it was still listed and obtained it for me. As for the gland; it was in good order and I re-used it.

Seals do tend to dry out when an engine has been sat for that long, and soon give way if pressed back into use.

The tube you're talking about is a greaser. Fill it with special thick water pump grease, screw it back in, and you might just be lucky enough to stop the leak. Don't fit a grease nipple, as too much presure will push the seal out. Give it a try, you've nowt to lose!

I've used EP services a few times, very efficient and not ridiculously expensive.

Thanks for the advise.
Can't complain too much, first thing thats not playing fair.

The leak is about half a cup in a couple of hours, will pack it with grease, water pump grease I presume, and see if it cures it, might need a couple of engine runs to get the lube. spread around?

Thanks for the 'EP' link will have a look later, might be able to get a repair kit.
Got a friendly local garage that will "Press" the shaft out if I need to, at no cost

BTW the engine is a Ford E93A with Aquaplane mods.

Leak cured, I hope

Acquired some water pump grease, stuffed the hole with grease filled the grease tube, refitted the greaser.
Ran the engine to heat and circulate some hot water.

Seems to have done the trick.

Thanks for the advice AGAIN

Roger
