4BD1 compatible starter motor

[Ben]

My starter motor made a bit of a mess of itself on the weekend and I'm not having much luck finding a replacement.

3539 3540

For ISUZU part # 1-81100-169-0 / NipponDenso part # 028000-6640, Repco drew a blank; the Arncliffe ISUZU dealer reckons there's no 12V units available any more, only 24V; Davis Performance Landys suggested an auto electrician would be the best bet; and as a premium member, I was surprised at the NRMA's flat response, "there's no Land Rover listed on our NRMA Electrics fitment sheet. We can't help you." End of conversation.

Anyone else replaced theirs with a compatible unit?

If it's a denso unit it shouldn't be that hard to get a hold of surely! Hell, the army must still buy hundereds of them from somewhere?

The army spec starter motor is different from the civvie one. I think it is a mitsubishi electric???

A mate of mine was quoted on a 12V denso starter by Don Kyatt in Brisbane. Price was about $1000, so he instead used a 24V starter and a switch to connect his dual batteries in series on startup.

Ben,

I might have something in the shed. Still buried, but I'm digging stuff out as I move to the new place. I'll keep you posted.

I've had similar comments from ISUZU direct (via phone)... but when I have taken in the part to them and after referring back through three generations of old parts manuals we have (so far) always found the part available under a new numbering convention.

the motor is still relatively common in oz, especially in the 'industrial' form where it is in backup power gensets and the like.

[Ben]

I've just dropped the buggered starter motor at the local auto electrician. There's always the rebuild option.

[EchiDna]

umm I got to ask - did it catch fire or what? looks pretty serious from the pics...

You are correct, I'm looking at right now

Mitsubishi

M3T67471

Well that all the numbers on it

[Ben]

Just speculation at this point as to the cause. Guessing the solenoid was energised while driving, engaging the starter pinion, and driving the motor to catastrophic destruction.

It had been running fine all Saturday morning, enjoying Stockton Beach. Then the last two minutes as we drove into lunch there was a bad grinding noise.

Turned the car off (needed to unlock the bonnet catch,) and popped the bonnet to check, and it wouldn't turn over after that. All I got was the solenoid click. The volts on the battery and the solenoid contacts were fine, so I relied on roll starting the rest of the weekend.

Checking the volts didn't show anything amiss, so opened it up and it was a mess.

Thanks for that. Google returns one page - Metcalfe's Mitsubishi starters (http://www.metcalfe.com.au/index.php?page=automotive&subpage=mitsubishi&level=jap). And they list the M3T67471 (http://www.metcalfe.com.au/includes/pages/automotive/images/jap37-67.gif)

Just to follow up on all the previous input:

That's what I assumed :) The old part number doesn't seem to match anything on the Australian websites, nor part supplier's databases. It seems the only people who care/know about these things reside here :)

Ouch :( I was hoping it'd be cheaper than that :eek:

Thanks for checking. It looks like I've got a couple of options now, so it's not critical, but let me now if it turns up.

Thanks for the tip. I got put onto the Arncliffe (Sydney) dealer, Suttons' truck parts. If I get stuck, I know to try the marine and industrial divisions.

Thanks Simon, I'll keep their details handy.

The local auto elec replaced the insides of (rather new) cases for half that, and had it back to me by lunch time today for me to bolt back on this arvo.

Once started, I disconnected it the solenoid lead and drove it over to him to look for what caused it to engage while driving.

Thanks to cal415 for his offer of helping troubleshoot it after Stockton. And also to Dobbo for his lamb oil spray to clean the contacts, and offer to leave the County over at his place on the weekend.

Well, this thread just got linked and I see I never finished the story!

The auto electrician said there was something glitchy with the ignition switch and when it troubled a previous owner, instead of fixing it they hooked the starter into the glow plug circuit, which apparently engaged it sometimes while driving.

WOULD LIKE TO LET YOU KNOW I HAVE PURCHASED A STARTER LIKE THIS PART# M3T67471 BEFORE FROM A US COMPANY CALLED RAREELECTRICAL.
THEY HAVE A EBAY STORE AND WEBSITE, IF YOU WANT CONTACT THEM AT INFO@RAREELECTRICAL.COM

Kim from Land Ranger said 1200 bucks for a new army starter, i got one fitted by the auto electrician up the road for 600 bucks. i can follow up if you wish??

Hello everyone, been a while since I've been on here.

I hope done right thing trying to dig up an existing thread re 4BD1 starter motors.

The old Mitsubishi 12 volt starter has got very lazy over time and is at point heating up all the cables whilst cranking off two 850cca batteries. I haven't bothered to look inside as over 30 years old etc.

If this Denso knock off works out, I'm happy to give the old Mitsu unit to anyone for spares as some of it should be salvageable.

I had concerns as looks a lot different. Especially fitting the turbo dump pipe back in as was pretty snug in there.

172042
Only concern I have is the terminal is very close to chassis. Time will tell.

Little bit of wiring to sort out as previous owner had heap of circuits running from here.

Regards

Hi you have a very dead Mitzi str throw it over left shoulder . The denso type is a better str org p/n 028000-6561 (tel:028000-6561) or 6560 ashy p/n nxs609 610incl or Baxter’s ns8348 680incl off the street prices .pm me l can supply through my auto electrical business. That str has been in mesh when running check key sw and str relay.

........... That str has been in mesh when running check key sw and str relay.

Had something similar with the geared starter in a 350 in my POS recently. Was only moving it a few meters, turned it off and there was 'the bad smell'. Seemed to be coming from the starter. Flattened the battery pretty quickly.

Disconnected the battery and undid the cover on the adaptor plate so I could see if the starter had stayed engaged, which it had.

On a Chev the starter is bolted on with 2 vertical bolts @ 90 degrees to the starter shaft.

Correct meshing of starter gear to flex plate is achieved with shims. Mine hadn't retracted because the bolts were loose and there was too much friction to disengage.

A bit disconcerting, but seems to be ok atm. Am using a battery disconnect switch till I get time to pull the starter and have a look at the pattern on the teeth, etc.

Doesn't look like Isuzus could have this problem,with the use of a flange mount. Interested to know if anything electrical could cause it in my case.

My 4BD1 starter has a free wheel on it, so that while engagement while running may wreck the pinion and freewheel, it should not damage the starter. But I don't know whether this applies to all of them.

Any thing from key sw ,str relay ;str sol can electrically hold str in mesh flange mount will bind if pinion dia or teeth count are wrong
