Hi all ,I'm presuming this is the correct fan pulley and pump for LCGTR? I'm going to replace the pump although it has the bigger diameter hub and slightly longer shaft.Can I use a puller and just swap the hubs? Ta Paul.

Probably wasting your time on old pumps? A press would be better.

I have a correct pulley and fan for that pump with the larger hub ,but the fan itself is larger and rounded at the blade ends which I think isn't right for LCGTR can someone confirm this for me please .Thanks Paul.

Rob,it's a good original pump with the cast impeller so I want to use it rather than one of those tin ones.

[rodomo]

Fair enough. I just think you'll struggle with a puller on the flange but good luck!

So did the LCGTR have the water pump with the smaller hub?

[Indy Orange]

I think may have EH HK smaller hub is this correct?

Hi Guys.

Many parts catalogues don�t list these pumps properly.

There are actually 4 different water pumps for the Holden 6.

1. EH to HK (small hub & short shaft) this has the common industry part no. of W587


2. HT to HZ/VB & LC to UC Without viscous fan clutch (large hub & short shaft) part no. W726


3. HJ to HZ/VB & LC to UC With viscous fan clutch (large hub & long shaft) part no. W814


4. WB/VC to VK Large housing & bearing (commonly called the 'Jumbo' pump) part no. W815



Type 1 has a unique (smaller) bolt pattern, so must be used if you want to retain the original pulley and fan.

Types 2 & 3 use the same pulley (as each other) and can often be interchanged; the only difference between the 2 is the length of the shaft in front of the flange. Type 3 is usually the one seen on cars with factory-fitted Frigidaire air conditioning.

Type 4 has the same hub as 2 & 3 but is further forward so its pulley has a bigger offset. Type 4 was actually introduced after the Blue motor intro, so early WB/VC Blue motors can be seen with the type 3 pump.

Hope this helps. Can we make this sticky, it comes up alot ?

Dr Terry.

I'm confused.If it has the small hub wouldn't be EH HK?

[Indy Orange]

These are what were taken off the car a 71 LCGTR which I now think is incorrect for the car ,as it's the smaller hub , like to hear from any LCGTR experts.

Thanks for the relply Col, ok so that's looks to be the large hub type , and if that's correct it means I have the wrong fan and hub.

[Indy Orange]

Pulley I mean.

[grumpy xu1]

Your fan is lc gtr mate

[Indy Orange]

Hi Gary, that fan and pulley only bolt up to that small hub, so the LCGTR had the small hub on the water pump?

[Indy Orange]

Anyone?

[grumpy xu1]

Mate, honestly i was sure the small hub was lc & lj was the start of the larger hub. & yes that is a lc gtr fan. Gary.

The LC & LJ parts catalogues all list the same Pulley for LC & LJ 6cyl.

Pulley for the HK 161 & 186 has a different part number.

LC GTR 2600S & 2850S are listed as having the same fan blade assy which is the same part number for LJ GTR.

[Indy Orange]

Then that cant be the original fan then,it is for the small smaller hub,pulley.

[RallyRed]

geez..I'm confused..your GTR setup is the

 

-small flanged pump,

-the small pulley

-and that fan

 

seems like a matching set to me?..or am I confused even more than I think?

 

The only thing wrong is the unpainted pump in your pic?...you can get a new correct one with the small flange, at Repco .
