Thread: Intro and series 3 heater

Welcome to the forum Chris.

In our experience just undo the screws and it comes apart, lube the screws and hopefully it will come apart. I know how rare these Heater boxes are, be gentle, they are a sort after.

Thanks MrsHH - that's what i thought but I have a feeling PO glued it with something. Won't budge with the screws out and unfortunately the other half looked like this

See how I go, thanks again

Could it be just rusted on? Have a go with a redundant pointed knife and some wd40 and see if anything gives. Otherwise a wreck is your friend.
Cheers,

Hello from Brisbane.

I'm a bit unclear about what part of the heater you are talking about here.

If it is removing the motor, and especially the impeller which has to come off as part of the process, it is fairly straightforward if you know what you are dealing with. Unfortunately, the manuals are useless in that regard - they just say to remove it.

If it is removing the impeller in order to get the motor off its mounting bracket and access to the front screws that you are puzzling over, you will see that it is apparently held on to the shaft by a zinc plated clamp. Once this is removed you would think that the impeller should slide off the shaft. However, it usually won't. What you can't see is that the shaft under the impeller has a small hole through which a piece of fine wire is threaded that locks the impeller to prevent it rotating on the shaft. My recommended removal procedure without breaking the impeller is to put the motor in a soft jawed vice and put a couple of long handled screw drivers between the motor and impeller and (having liberally used penetrating oil beforehand) put steady pressure on the job until the impeller starts to move on the shaft. Once it clears the wire it usually slides off. You can then access the front screws and it all should come apart fairly easily.

Now if that is your situation I hope it is useful. Should you find that the motor is stuffed anyway there is an auto electrician down Coopers Plains way who can fix them. Wreckers are an option but the part could be 40 plus years old and not much better than what you have.

Thanks for that guys. Neil, yes got the motor off and the impeller no problem, as you say except I used a punch on the top of the shaft with a gentle tap and 2 chocks of wood between the motor and impeller, worked a treat. Tested the motor...buzzed like it came out of the factory yesterday in high and low! I love landys.

Once I had the heater box out it became pretty clear...it's not the front that comes off but the side....my bad. No damage done though in the process so that's good.

This is how it looks currently:

Plan is to chop the rust back, patch with a bit of thin sheet metal and some pop rivets, add a small drain hole and a coat of paint and it'll be like new.

Just out of interest what do you think is the best way to clean the core?

Cheers, Chris

Chris,

Hello again from Sherwood.

Glad to hear you got the impeller off without rooting it. Ditto the air box.

I got my heater core rebuilt by a small radiator repair place in Wooloongabba (Airrad in Annerley Rd). They didn't charge much ($40?) and did a good job.

Cheers,

Neil

Good to know - thanks Neil, I wasn't planning on getting the core rebuilt just yet, I think it has a few years left given the stretch its just done! But when the time comes...in the meantime I'll add to the maintenance list and check it every couple of months.

Good to know there is at least one other enthusiast in Bris, are you aware of many? I'm in paddington btw.

Cheers, chris

Chris,

Hello again from Sherwood.

I hadn't really looked at the photos that you posted earlier of the heater box but can now see that it appears to have been modified at some stage. The original would have been held together by small pop rivets and more than likely there would have been a heater tap mounted to the side of the box. Yours seems to just have a hose directly exiting the box from the core presumably heading to the back of the head or the thermostat housing. Does it have a tap?

Incidentally, a photo of the truck itself would be of interest to the crowd. Plus if you aren't already a member of SLow then let me recommend changing that status as a worthy New Year's resolution.

Cheers,

Neil
