flatty waterpump issue...(SOLVED) (UPDATED)
While I was working on the front of my 36 Flathead I ordered a pair of new improved water pumps with the ceramic bearings and I installed them late last night, this morning I go to crank it up and one of the NEW pumps is not rotating past a certain point :mad: it will lock up solid, I cannot even budge it with channel locks, see remedy below! :D Sorry for the rant, just had to vent. :( |
Re: Dennis Carpenter new flatty waterpump issue... Have you removed it from the cylinder-head to inspect it yet?

Re: Dennis Carpenter new flatty waterpump issue... Sorry you are having issues. I have Dennis pumps in my 39 coupe and in my 52 F1.
Truck 2 years Car 5 years No issues. However I should mention. Since the truck needed so much work, the pumps sat on my shelf for over 6 months. When I was ready to install I noticed one of the fins had a crack. I called and while long after purchase they replaced the pump free of charge. I can’t recall if I paid for postage to return damaged pump. |

Maybe something accidentally fell into the pump like a bolt or a nut.... |
Re: Dennis Carpenter new flatty waterpump issue... caj,
I have had good results on two recent builds.....'34 and '36 with DC head mounted pumps. Drain it and see what's going on, the guy at DC will ask that when Tuesday rolls around. Charlie ny |
Re: Dennis Carpenter new flatty waterpump issue... Did it spin before it was installed? Sometimes new stuff doesn't work. I changed plugs in a modern ride due to a miss. The brand new plugs I installed had one bad one in the box. This caused a lot of more work till I got back to the plugs!

Re: Dennis Carpenter new flatty waterpump issue... I'll check into all of that in the morning, its been cooler in the early mornings here on the Gulfcoast lately (come on early fall!) and I'll will take it off in the morning.
Thanks Gents. PS: please lets all say a prayer that all of our hot rod friends and families in Florida stay safe from the hurricane, its starting to look really bad! |
Re: Dennis Carpenter new flatty waterpump issue... My guess would be the impeller May be hitting the cylinder head. I’ve used drake and carpenter 21 stud pumps with nothing but great results. I do prefer the drake ones over the carpenter pumps

Yes, after further review, your right on the money Michael! After I cleaned this up with a grinder and was super careful to protect the surrounding area and inside of the head of debris, all is well now. Pics below from L to R

My reasoning for liking the drakes better is small. I only keep carpenter pumps on hand as I am a carpenter dealer but not a drake dealer. In the attached photos you will see the drake pumps have slightly more impeller vane surface area and a tighter tolerance in the housing. Either way both have ceramic seals and modern sealed bearing which in my opinion is superior to original bushing designs for a driver type car. For a show car they are not correct. .https://uploads.tapatalk-cdn.com/201...9e161f638d.jpgAttachment 405626 Sent from my iPhone using Tapatalk |

Re: flatty waterpump issue...(SOLVED) Actually the drake pump is on the right side of the photo. A side by side trail showed no real difference in cooling temperatures... but a side by side with a original did.
Thanks for the comments, we are a very small husband and wife business and I do all the rebuilding work. |

Re: flatty waterpump issue...(SOLVED) Well done on finding the cause of the problem. Sometimes you just have to get in there and get your hands dirty. It gives you a great sense of satisfaction when you encounter a problem, identify the cause and effect a solution.
And by sharing it, it can help others avoid the same problem. Mart. |
Re: flatty waterpump issue...(SOLVED) The same thing can happen with Skips pumps on the 21 stud engine due to the large impeller.
