Thread: Isuzu starter motors

Anymore info scott? Is yours an Isuzu truck one or a landy one??

Just had a quick look on ebay, and apart from the usual suspects from USA, there's this local supplier with 5 year warranty for $400
Specs say its 11T and CW but you've said 9T and CCW so I'm not sure which is correct.

Starter Motor Fits Landrover 110 3 9L Diesel 4BD1 Engine 1984 TO 1994 | eBay

Search ebay on "4bd1 starter" from seller Auto8 if the link dies in the future.

I'm using a new JAS Oceania - eJAS Home The websites not much help unless you register.

Reading off the box - model SNJ004 12v 2kw 9 teeth clock wise (CW), suiting denso, application holden Jackaroo, Rodeo. Haven't run it yet as my vehicle is in pieces.

My engine is from a truck - going into a RRC chassis - missing 12v alternator and starter (it actually came with a 24v alternator). I was buying an adaptor from Outcast in Brisbane so I asked them what alternator and starter they were fitting to their RRC conversions and asked them to get the same.

Dummy fit gives about 10-15mm clearance between starter and chassis.

4bd1 are CW starters I would have bet money on it being 11 teeth maybe different flywheels used? The 4he1 are 11xCCW as they are mounted to the rear of the bellhousing .The 4bb1 in my boat is
CW x 11

Should have put a bit more detail in my first post.

My truck is a 4be1 in an 85 county. I am going off what starter is in it at the moment.

Looking on ebay I can only see 11 teeth. Does it matter if 9 or 11 as long as same modulus or pitch or what ever?

There are different ring gear sizes to fit with 9t or 11t.

Any information on this. For example, is the ring for the 9 tooth common to the LRover units and the 11 tooth to the truck, or vice versa.

I'm not an expert on this and what I did understand is rusty I have a module 1 set of gear cutters - 8 cutters to the set from memory. Not precise but by way of example, the first cutter is used to cut a gear containing 11 to 13 teeth, the next cutter for 14-16...the final cutter for a gear or rack with 30 or more teeth. So you can have a varying number of teeth. The small gear can have 11 or 12 or 13 teeth and will run with a larger gear having say 25 or 26 or 27 teeth. I believe if they have the same form and pressure angle the number of teeth can vary but they will run happily. Happy to have someone with industry experience chime in here...please!
