155 pump

[pioui1]

I received this pump and I had the removed the impeller,I did not removed or play with a set back pump in a long time, is this normal,I am talking about the washer ,because it's a machine shop that I don't know. who put the pump together ,

thank you for your help

Yeah, you can add or remove the washer to get the correct prop/stator clearance. If you get the "right" clearance with the washer its good, if to much clearance, the setup will be too loose and you might need to put a thinner washer or completely remove it.
Its a bit like exit nozzle diameter, there is no correct and wrong "number" its all about YOUR setup and get your pump loaded to the max, that your engine can push

thank you

No that is not normal, impeller washer should fit into pump nose. Remove the impeller washer and post another pic, but my guess is the wrong thickness of bearing was used on the front and shaft is sticking through too far.

 

[pioui1]

thank you Christ That is what I thought to I will put another picture

 

[pioui1]

the second one

I will bet the pump was assembled with std SJ pump bearings instead of the wider setback pump bearing kit. Disassemble pump and see if the same bearing is used front and rear. Should have a wider bearing on the front of a setback shaft. Don't run the pump that way.

JM for the win again. Nice work

 

[pioui1]

I will open the pump in the next 15 min

 

[pioui1]

thank you very much Christ, I did have the time to remove the shaft

 

[pioui1]

this the the bearing in back of the pump,

 

[pioui1]

this is the pump with the front bearing stuck in it

 

[pioui1]

I used the vernier to see the distance

 

[JetManiac]

Use the other end of the caliper to measure the thickness of the bearing in the pump.

 

[pioui1]

OK thank you Christ,I put some pictures of the stator so you can see bearing ,I am not sure about the distance in between the seals and the bearing

 

[pioui1]

I did measure the bearing inside of the stator and I have 15.37 mm

Chris will hook you up with the correct parts. That was a short 15mm bearing. You need the double row one that is 5mm longer. Measures 20.6 wide.
