My way cool water pump!

So freaking cool.

I nominate Verell as man of the year. Is there anyone out there more willing to help a guy out??

I need someone like that to help me re-do my brake calipers!

 

The bestest looking water pump I've seen!

Verell, do ya think you could make a business out of just rebuilding water pumps for us?

 

Jerry just move EAST to the land of snow and salt

Verell would get my vote!

 

Jonathan,

Here's a thread with some numbers for you from my 328's waterpump (WP) rebuild that was done during its 30k major service in May/June:

http://www.ferrarichat.com/forum/showthread.php?t=20753

Looks like I, too, had two large bearings, a gasket, a seal, and some other miscellaneous parts. My parts came to $123 total, and labor was built in to the major service...

Mine's not power coated, though! That sure does look nice. It's an extra--would everone who just "needs to get the friggen waterpump rebuilt so my car can get back on the road" opt for that?

The other issue you face is, unless someone can Remove/reinstall their waterpump by themselves, they'll probably just take it to a mechanic and have them do it...

Poweder coating aside, which was harder--the WP rebuild itself, or the remove/reinstall?

I'm in - the tech section nominee for FCHAT Man o' Year!

 

Neither is particularly hard. Probably 30 min to remove, 30-45 min to rebuild, & 30 min to reinstall. This includes jacking the car up, removing the passenger side wheel well liner, & belts.

Biggest PITA is the big c-clip that holds the inner bearing in place. You need a strong c-clip tool that can reach way down inside the WP nose. On reinstall the cone washer that's between the bearing & the c-clip is very hard to get aligned. Probably spent 15mins getting it in place this time. Usually quicker tho.

Double those times if it's your 1st time thru.

Luckily, we were able to re-use the c-clip, cone washer, & impeller locking tab. They're usually part of the std rebuild kits, & often are in rough shape & need to be replaced.

Umm, that isn't just 'silver' powdercoat, it's 'chrome' with a heavy clearcoat so it should hold up a long time. The powdercoating was done before reassembly started.

 

Magnificient! Bravo!

 

Verell,

Next time you rebuild one can you take pictures and do a step by step write-up? I lucked out when I did my major as I found a new pump for cheap. My problem is the 30 hours it takes to get to mine

 

The injected, & possibly even the newer carb'd cars have the cam belt covers machined so that the WP can be removed w/o pulling the covers.

robertgarvin:
The 308 GTB TechTips WP rebuild procedure is pretty easy to follow:

Matt Boy'ds writeup on ExpensiveCar.com is step by step w/pix:

Umm,
If you heat the wp to about 250 F, the old bearings will usually just drop out, & the new ones drop in...

Thoroughly clean the inside of the WP housing, trying to press a bearing in on top of a lot of caked-on deposits is a great way to crack the housing!

A long & strong c-clip tool is a MUST.

The smaller diameter side of the cone washer goes against the bearing race, larger diameter against the C-clip. Keeping the inner side aligned on the race while installing the c-clip is necessary & may take longer than the rest of the rebuild..

 

Great write up.
What is the part number for the Mcmaster carr bearings, and where do I buy a "409" waterpump seal.
thanks,
Martin.

Verell,
according to Ferrari data I have the fourth last built carbed 308 GTB and replacement of the waterpump is the same pita like on the older cars, because the cambelt covers are not machined.
Since I did the translation - and some additions - of Carl's procedure on Robert's website you mention above ( www.r-design.net/308 ) for the german language section I know about the machined covers, though I have never seen any.

Best Regards from Germany

Martin

 

Umm,
Happened to be looking up the phone for my local bearing supplier.
2 years ago they gave me this price for the WP bearings:

3x8 water pump:
Lg Bearings:
SKF W 6302-2RS1
(w for stainless steel $30 in SS, $12 std)

Sorry McMaster was more Jonathan, but I did suggest you try a bearing supply co at the same time.

Martin,
The newer cam covers aren't machined, Ferrari changed the casting design to give the necessary clearance for servicing the WP. As to which WPs the 409 seal fits, see the WP seal thread:

Was sorting the pix from my camera & thought you'd appreciate the attached pix of Birdman's waterpump.

1) WP housing after several attempts at removing the discoloration by washing with several solvents.

2) WP housing fresh out of the powdercoating oven

3) Exploded view of all parts just before rebuilding the WP.
