Cutting the water pump shaft - TD27

Postby fullthrottle » Wed Feb 06, 2013 8:13 pm

Sounds scary I know, but does anyone see a problem with me slicing the end of the water pump shaft off (just after the pulley)

Shaft.jpg


It's on a TD27T engine.

The reason, well I'm going to solve my overheating issues once and for all with a twin Ford Falcon fan unit. It is almost exactly the same size as the radiator, with some minor trimming, but I just need 10mm off that shaft. I can take 20mm off it no problems.

Yes it overheats...still. Only when doing very, very long hill climbs.

really? whats your EGT reading? i treat mine like it's a v8 supercar, periodically hitting 140 kph (i don't condone it) up some passing lanes and never has gone above half?

get an intercooler on it makes a big difference

but yeah, if you aren't going to use the viscous fan you can trim it flush with the pulley if you want to, just remember if the water pump needs replacing you'll have to trim that too.

Cheers

Yeah sure does. Very slowly though and when I say hill climb, I mean you are climbing continuously for at least 30mins on offroad tracks.
The viscous fan is going continuously, so it can't do anything more than what it already is doing.

Don't have an EGT yet, I'm slowly getting to the engine part. As of now its still a stock standard TD27 Turbo.

Right out comes the power hacksaw and grinder then :mrgreen:

Have you had the radiator checked for flow and pressure? Often they have good pressure but are restricted in flow which is the common cause of overheating. Especially one that has heated up and disturbed the sediment in the bottom causing it to block the tubes.

Last year had a mate with overheating problems, told him it was radiator but his mechanic supposedly had it checked. 6 months of overheating later, a complete rebuild of engine as it had supposedly blown heat gasket, replaced all temp senders etc as they were supposedly crook and it still would get hot. They finally got radiator checked. Supposedly the radiator guy didn't check it originally .................

I wanted so much to say "I told you so ............ !"

The old 'Tauras 3.8 e-fan mod' :D

Will there be any issues with charging system? I hear they use quite a lot of juice.

Maybe a stupid question but would there be any benefit in keeping the viscous and adding a front-mounted pusher fan to help it out at low engine speeds?

Cheers for the heads-up. I think I'll go with a slow hacksaw cut and then just file the burrs off.

As long as the alternator puts out as much as the Falcon does, there won't be an issue. But the Alt is also being changed. So no issues for me.
Room in the front of mine is even less. I did think about that. Cheers

Cool, looking forward to seeing this.. the falcon fan will make a cool noise too. Interested in your alternator swap/vacuum supply too.

OK, first problem.... cutting that shaft off is a right bugger.

Was slowly cutting through it no problems and then you get to the center shaft which appears to be 10mm of solid hardened steel. Hmmm more industrial action is required.

Start engine, hold hacksaw to spinning water pump, rev engine up to desired speed, :mrgreen:

Note: no responsibility is taken if something goes wrong haha

Stuff that mate. I've tried the hacksaw by hand for at least 30seconds, doesn't even touch it.

Got it now though, just hacked it off slowly with the cutting disc on the grinder.
Small cuts and cooled by water after each cut... lovely jubly.

How did you go about even removing fan hub? Supposed to be a 1 pc unit aren't they?

Cable tie the garden hose to the alternator bracket and aim it at the pump shaft, turn on.

step two 12 inch steel cutting blade on a saber saw and go for gold.

or if you into making more noise a grinder will do the same thing, and probably quicker too, bit of a bitch to get in there with it though.
