Anyone tell me the part No for an LC XU-1 starter motor ? (bosch or lucas) ?

Hi

The LC parts catalogue only gives one P/N for the 186X starter motor - that being a Bosch P/N 2812679

Cheers

The parts book says that the motor which Bazza has given you the number for was also fitted to the 2600. It seems that Lucas starter motors were the other choice (but not for XU-1) and these were also fitted to 2600 motors as well as the 2850. My book has a pen amendment which reads '9947262B' as a possible alternate for the 2812679 starter motor.

I see in the LC parts catalogue 2812679 for the 186X starter motor, as Bazza has said. However, the LC XU1 supplement shows the part number for the complete starter assembly as 7431089, though it isn't listed as a New Part. And yet, all the part numbers in the XU1 sup, for the bits that make up the starter motor, are identical to the LC parts catalogue. Does anyone know what this 7431089 is?

Hi

That's odd. 7431089 is mentioned in the numerical index at the back of the Feb '72 LJ catalogue - but doesn't get a mention in the body of the book at "2.041 MOTOR ASSEMBLY - Starter" where it should be.

Hi Dave

No need to be sorry, Part Number 7431089 is definately not there - I don't know what edition I have (front cover missing). I thought it was the latest because it has the 2850, 2850S and CK parts.
My most recent comment was more to do with the anomaly in the LJ catalogue.

Hi Bazza

Checked my Feb 72 LJ parts catalogue and found the same anomaly with that part number listing.
My catalogue also contains a second loose leaf numerical index which is obviously a GMH parts book update to rectify errors and it doesn't have the 7431089 part number listed.

I thought your LC parts catalogue might be the earlier 1970 blue cover edition but if it was it wouldn't have listings for the 2850 engines. Very Strange indeed.

I suspect the XU1 supplement is a later edition and is in error; I suspect someone has transposed an LJ part number into it. That's my guess...

No, the XU1 supplement comes after the very 1st LC parts catalogue which would have been published sometime before the XU1 was released. Most likely starter motor Pt No. 7431089 came straight from the HR or HK,T,G 186s engine so would not have been listed in the LC XU1 supplement as a new part as it was an existing part albeit in a different model.

Ok. Would be interesting to see what the difference is in the two starters. Having a look at the parts that make up the starters, the numbers seem to be the same between the two.

Strange isn't it.
Two supposedly different Bosch starter motors (probably different torque ratings) and yet all the service parts are the same.

Hi Guys,
Looks like you all are starting to realise the traps of believing all you read, I have a page full of mistakes in the parts book just for the 73 models.

The parts books from memory indicate that 73 XU-1's had Bosch starters, yet my friend with a low milage 73 LJ has a Lucas starter and alternator.
I think the book is wrong with the late starters especially as weight saving for racing purposes must have been a consideration,
I have not rechecked the parts book lately though.

Lucas Torana starters are shorter than the Kingswood units and are much lighter than Bosch due to Aluminum windings, the Lucas Alternators are smaller and lighter than the Kingswood ones too.

Hi Mike

Yeah I've known for years that parts books have mistakes. I did some time back in '85 as a Holden parts interpreter.
I also have quite a number of GMH letters advising dealers to update mistakes in parts books.

Another reason for part numbers that may not match between earlier editions and updated editions of parts books is supercession of parts. Sometimes a revised part from later production of a current model would be suitable to earlier production models so when an updated catalouge came out only the later part number would be shown as the earlier part would be discontinued.

Another thing I have learned is sometimes parts were be found to be inherently lacking in quality or durability so a new and improved part was produced and GMH would instruct Dealers to replace the faulty part/s when the affected vehicles came in for service without even a word to the owner about what they have done.

Also parts would be superceeded by an improved part that may appear different in some way to the original part but the part number doesn't get changed.

Oh by the way, seeing as you want have a dig at my sign on name maybe VZ S pack will set your mind at ease.

Mike, I find it interesting that no one here has indicated they have a Lucas starter motor in their original LJ XU1.

Do you know the horsepower rating of the Lucas starter in your friend's car?

Like you have said, only Bosch starters are listed for the LJ XU1. These Bosch starters (P/N 2825508), 9000 063 025, are rated at 1.3 horsepower. SO presumably, your friend's Lucas starter should have this rating as well.
