I had to buy a different pulley, as the mods to the water pump would have been more than I care to make. As in grinding away much of the 'snout' of the pump. | ||

Is that modification done on the water pump or on the block? If it's on the water pump, is there anywhere I could just buy a modified water pump? | ||

Rather than rebuilding the old style water pump on my 77 308, I installed the "new improved guaranteed to make your teeth whiter" style water pump thinking it would be a smart upgrade. If I remember right, the only modification I had to make was to grind a small area away on one rib to clear my old pulley. Otherwise it's straight forward once you wade through all the crap to get to the water pump.  | ||

I seem to remember reading somewhere that installing a 328 water pump in a 308 isn't so straightforward. Anyone know for sure? | ||

My '83 QV pump seized up a couple of years ago and my mechanic put in a rebuilt 1989 328 pump, which he said was much better than the QV ones. | ||

308 GTB REGISTER IS WRONG ABOUT LARGE BEARING CUT-IN ----------------------------------------------------------- My '82 Euro 308 GTS QV has a large bearing pump. The best I can pin the large bearing pump cut-in down is that it occurred somewhere between Jly '78 and November '81. I researched this in depth using a larg number of FPCs back last December. The results w/FPC references are summarized in my post #:465 in this thread: http://www.ferrarichat.com/discus/messages/256120/184361.html The following thread has some vy good(IMHO) tips from my WP rebuild a couple of years ago: http://www.ferrarichat.com/discus/messages/256120/454.html | ||

Verell, According to Carl Jones' tech tips over at the 308GTB Registry site, the large bearing pumps were introduced with the 328. I had a 78 308 GTS and it had the small bearing, until I upgraded it. | ||

get one from teh dutchman he advertises in hemmings...I got mine there and it was great value and is working great.. beware of the "new improved ones" they have a plastic impeller (oh sorry composite) but ask anyone who repairs BMW's (some of thsoe models have thes type of impellers..they are supposed to be lighter so more efficient and use less HP ..like we are going to notice..) anyway they have a nasty habit of breaking up inside your system...not much fun | ||

Dave, All of the injected 308s should have the large bearing pumps. The large bearings were introduced in the late '70s ('78 I think). (Unless someone has repl the orig. pump with an older small bearing one.) What in this thread led you to believe that Gary doesn't have the large bearing pump? BTW, Gary if you've got the small bearing pump, Consider upgrading. The small bearings just didn't hold up. The other question is does he need the large or the small seal? | ||

I thought the QV has the "large bearing" pump...Since it sounds like it doesn't, and yours has not been updated, I agree with Don, buy the new one from Ferrari UK. It will save you in the long run.... | ||

You can make up your own kit if you can locate the seal & gasket. The bearings are an industry std size. You can cross-reference from the part #s on the old bearings, or by measuring them & making sure you get bearings with dual side seals. If you have trouble figuring the bearings out, send me eMAIL, I may have photos or notes from my rebuild somewhere. The bearing-bearing spacer, C-clip & spring should be good enough to be reuseable. Kits used to go for $100, real shame if we're now forced to go $425 for lack of a few replacement parts! | ||

I have been calling all the parts people and they are saying to trash the old water pump and get the new and improved verion. I think a rebuild will work but no one has a kit anymore. Any thoughts ...... Gary | ||

Geta ~1" dia steel wire brush & a drill or die grinder to turn it. Makes cleaning out corrosion & other deposits from the bearing mounting area easy. IMHO, most rebuilds that don't hold up due to pump housing failure are because the old inner bearing was pressed out, and/or new bearings were forced in over corrosion/deposits on the inside of the housing, cracking the housing in the process. Clean, then lightly grease the housing before pressing bearings in or out. You'll need a fairly hefty C-clip tool, or else grind down the tips of a pair of heavy needle nose pliars. RTV gasket sealant. Permatex/Loctite make a grey RTV especially for water pump & other coolant applications. However, any good RTV is fine. Use it sparingly as a gasket dressing. Note carefully the orientation of the conical spring washer that is between the c-clip & the inner bearing's outer race(say that fast...). You don't have to have a press, altho it's best. Most auto machine shops have one & will let you use it free, or for $10 or $15. If no press is available, support the housing in-line with the bearings with wooden blocks. The bearings can then be tapped out/inserted. One of the bearings may have siezed & spun the outer race, thus making the housing over-size. Loctite makes a bearing/bushing sealant for inserting bearings into over-sized housings. Alternatively, the worn housing surface can be built up with JB Weld, then re-machined. | ||

Wouldn't know, never done one....usually leave it to my mechanic, since I don't have a press to remove/install the bearing (s?) | ||

Dave, I knew you'd have the answer. Anything else I would need besides the kit, O ring, and belt. I've dealt with both, Rutlands and Dennis. Both seem good. Thanks for getting me going ...Gary | ||

That's easy! Check any of the sponsors on this site. Also good would be T.Rutland's, Parts Source, Dennis McCann, etc....they all carry the rebuild kits. | ||

Do a "Google" search for '308 gtb registry' and also www.expensivecar.com both of these sites have the service procedure for rebuilding your waterpump and install/removal. | ||
