Jg pump problems
« on: February 05, 2020, 04:22:53 PM »
Getting ready for the burley Idaho race was checking  my pump out ,the input shaft seemed to move back and fourth about a 1/2 inch and it spins pretty freely the impeller sounds like a tin can noise,  talked to George at ars marine he built the pump  said it might sound like the thrust bearing , pumps only 3 yrs old after a 3000 dollar rebuild real bummed , last year blew 2 motors one my brand new stroker motor broke in the first 20 minutes  had a roller lifter fail ,brand new everything  , took out the block and camshaft  and then scrambled to get my back up motor fixed that had a blown head gasket  then after the swaps lasted until late August  then blew another head gasket now I get to pull the pump and send it back to George  this really sucks , but I'm not quitting!! 😠

Sorry to hear that bro , George might be right on the bearing but 1/2 run out on the shaft ???? That allow the impeller to hit the suction housing???? Also that would push the shaft into the driveline and possibly push the crank ??? , better  check the driveline . Best of luck brother

Oil in the bowl is not a big problem, seal leaked or possible that it came out due to shaft travel . If want the pump done to race spec then contact place Diverter and controls and talk to Tim place . He once had the fastest jet boat in the world and knows how to build pumps . He has a bad ass pump ready to go . I posted here in SoCal Jetboat . Call him and maybe he will give u a deal for it .

I'd pull it apart and see what's going on. Several places have an impeller puller. Hopefully the wear ring isn't welded to the impeller. And the wear ring didn't take out the suction housing. Sounds like the bearing slid up on the shaft?

Thanks guys , got the pump pulled today sending it to George at ARS, he built it before , hoping  the housing is not messed up this would be my 3rd in 4yrs last housing cracked because of a broken piece of metal from a bad assembly line loader scoop , so we'll see ,appreciate  the help , George has always been good to me ,parts fail I understand  plus I'm hard on my equipment  I'm always checking everything  but shit happens if  the new motor fires up and works out I should be ready to rock and roll for the June race😁

Well got the news from George at ARS guess the thrust bearing failed , got lucky and the housing is not cracked , he asked me what kind of grease I was using on the thrust bearing  , I use Lucas  oil grease , does it make a difference? I always greased it before  and after I ran the boat always changed the oil too, hope I get the pump back soon   hope all you out there are doing all right the world's kinda crazy this virus shit sucks😠

Use black moly lube on it . And brake it in a little no hard passes for about 15mins then put a couple of squirts in at idle and the go for it

Did you allow the water level inside the boat to get up to bearing level?

thanks for the info , so black moly lube any specific brand ? do you recommend a good gear oil, been using Lucas oil brand, as for letting water up to the bearing, when in the pits its only getting water from the pump , in the river it sits for about 15 minutes before I start and run it, are the thrust bearings pretty much the same in dominator pumps the same in berkely pumps? was this a bearing fail on my part, or a cheap bearing ? or it just failed, the pump is
 just 3 yrs old from rebuild  any other info would be great ,appreciate the info words of wisdom from you guys ,still waiting for the pump from George , thanks again

Bearings are all the same in berk and Dom , itís the manufacturerís that are different. Nsk , zpl, timkins. Just have to get the better one nsk is what I would use . As for the molly lube , Lucas makes it . U want one with high grafite . Hope u get ur pump back soon . Just make sure that when u get it back get the parts list and see what bearing went into it . Check the bearing and make sure itís been pre greased . If u have any questions pls pm me and I will give u my cell number an we can talk .
