oil pump - HELP!

[Bl4cK32]

I posted this in another thread but...

OK so how do i get the Crank timing pulley off then. NOT the Crank pulley, the one behind them, in front of the oil pump which the timing belt goes around. Does it come off with the oil pump, cos it seems that the pump is free from the block, but the timing pulley is stopping it and i dunno how to get that off.

Your help is appreciated.

Hi Bl4cK32, the pulley is keyed to the crankshaft, they usually slide off after a tap or too from a plastic hammer. If not then a universal puller does the job, cheap from Repco.

Hope that helps

are we talking about the same pulley? I cant get a hammer to the pulley cos its covered by the half ring on the oil pump. I cant use the puller again - i haven't got a tap set to screw in some bolts to use it.

Hi Bl4cK32 , use a screw driver with the blade on the inside of the pulley grooves, hit the head of the screw driver with the plastic hammer. Three or four places around the circumference are accessible, give each a tap or two. One clockwise and one anticlockwise, that usually works.

If not, the puller style you need has 3 arms with hooks on the end which go behind the pulley. The screw butts up to the front on the crankshaft, so as you wind it, the claws pull the pulley forward off the crank.

Tapping usually works, but occasionally you get a stubborn one that needs the puller.

Hope that clarifies

Black32 did this work for you? I am struggling with exactly the same thing as we speak.

Sydneykid, I am struggling to get anything between the pulley gear and the plate behind it without bending the plate - are there any other tips at all coz I'm really strugling...

Thanks.

Hi armbrush, this seems to be happening more often than it used to. We had one in the machine shop last week that we had to cut into 3 pieces with the angle grinder to get it off the crank. The good news is if you have to break the pulley they are pretty cheap to buy.

I can't really add any more than I have, they usually come off with a few taps of the hammer. Stubborn ones we use a puller on and if it gets really bad we cut them off, but I have only had to do that a couple of times.

This is the type of puller we use;

This is a US supplier, if you print the picture out and take it to your local Repco they will have one.

I hope that is of some help.

Usually a lot of crap and some rust forms between the crank and the fitting (cam belt drive or harmonic balancer) so spray in plenty of lubricant and wiggle and turn and assist with the screwdriver. Done a few in the last month.

If you have the engine out this is a lot easier, but if it is in, and you are trying to remove the oil pump, you have to drop the sump as the oil pump has a big bolt head that protrudes from the bottom and catches on the sump. Found this out doing a quick front oil seal replacement that wasn't so quick.

For replacement seals for the oil pump and the cams, the RB30 front crank seal is choice and cheap and is at REPCO.
