Water Pump Question

Postby reb54 » Sun Apr 05, 2015 1:00 pm



I replaced my water pump with one from Honda and used the proper coolant. Probably put atleast a thousand miles on it before the bike sat idle for 5 years. Upon putting the bike back on the road (replaced the coolant again with the proper fluid) for 2 years and 10,000 miles later I noticed it has developed a drip from the weep hole on the pump. I thought the pump would last much longer and wonder if the sitting up for 5 years contributed to the dripping.
Also need an opinion, I have a camp out comming up (700 miles round trip) and would like to put off replacing the pump untill after the trip. If I keep an eye on the coolant level do you think I will be alright?

Just found/fixed the leak in my #3 carb will help from this site!

Thanks,

I dont think it will be the water pump itself, the new seals with the water pump, are prone to leaking if they are not quite positioned properly. I have the same problem, after replacing the water pump about 2 years ago.

while its impossible to say whether it could cause problems on your trip, or not, I can say, for me, it seemed such a big job, to fix a small problem, and I decided to just keep an eye on the coolant levels. most of my riding is long distance, and up to now there have been no issues.

Thank you for the reply. I was wondering if it could possibly be an o-ring or seal but usually I am not that lucky. I guess if the shaft does not wobble, the o-rings/seals would be the culprit. I will purchase a Honda gasket kit and install it after my trip. Your information has been very helpful.

These seem to leak some when they have been sitting a while, as well. As soon as you ride them a ways to get them hot and comfortable, the leak seems to disappear. But: Be ever vigilant :shock:

The world is not going to finish today, as it is already tomorrow in Australia and New Zealand, and other islands of foreign nations such as Guam and Samoa.

Thanks for the reply, I am going to keep a very close eye on the coolant level.

A lot of them leak a few drops now and then when sitting for a while in cold temperatures, but then seal themselves up once they get ridden. If it's only a few drops, I would perhaps take a small bottle of coolant (just to be safe) and keep an eye on it, go do your trip.

My 84 had a slight drip under it every morning after being parked overnight. It remained that way for literally years. I finally replaced the pump because I was just tired of seeing a drop of coolant under the bike. Your problem sounds similar, and can probably be put off until another maintenance session.

Thanks for the reply WingAdmin, I am packing some coolant. Also working finishing a trunk I picked up off ebay and used your article on using the abs plastic to reinforce the rack.

tom84std, you live fairly close, I live in Carrollton. May need to meet somewhere and talk about our bikes......

An update on the water pump. Got back from an 800 mile camping trip on the bike and did not see any drips out of the weep hole on the pump. Will continue to keep an eye on it.
