Does anyone know how to work out much from victa engine numbers, i have been taking log of all mine at the moment, and i cant work out any stable pattern, some are longer, some shorter, and some appear to have the year while others dont.
All i can work out so far is that, the series 70 engines before 76 seem to have the year in the number (i have one that i was sure was 1973, and it had 73 in the number when i checked, same for a 71, 72, 74 and 2 more 73's) but then later in the 70's, the number moved to the rear of the crank, got harder to read, and now does not appear to have a year reference.
the earliest ones (my Specials' etc) have much shorter numbers, but with no discernable year value.
Anyone got any idea how victa worked out the engine numbers?
Cheers Ty

Hi Ty.I'm not sure if I can help you with the engines number that you are looking for however I do know some of the sequences for the earlier models.They are as follows.These are for the victa's Model 1 1 to 10,000 With no 125 on the front crank case.However there is some debate that it only goes to 8,000 Now.The first 400 had letter with them,these engines where made to run pumps not mowers. Model 2 10,000 to 100,000 Model 2A 100,000 to 110,000 Model 4 Automatic 110,00 to 130,000.These were all straight numbers no letters where in there. I have also found that the Model 3 numbers were usually over 140,000,but don't know to what range.After that the number system was thrown out the window. I hope this helps in your research.
Here for a good time,not a long time.

That is great for some of the earlier ones i have, your right about it going out the window, looking at some of my 70's & 80's engines, it makes no sense.

I think i have worked out some consistency with the Series 70 Numbers, Judging by the ones i have collected sop far.
For some (earlier ones) they show 2 digits for the year, later they only showed one.
Here's the key:
First Digit = 0-1, and 6th digit = 0: Last 2 Digits of year are positions 4&5 First Digit = 2-9, and 5th digit = 0: Last 2 Digits of year are positions 3&4 First Digit = 0-1, and 6th digit = 1-9: Last Digit of year is in position 4 First Digit = 2-9, and 5th digit = 1-9: Last Digit of year is in position 3
Examples
11371098767 = 1971 (Key 1) 02373066723 = 1973 (Key 1) 1629033645 = 1979 (Key 3) 5480667000897 = 1978 (Key 4) 034770667399 = 1977 (Key 1) 034706673999 = 1977 (Key 3) 034700673999 = 1970 (Key 1) 237609987767 = 1976 (Key 2) 1760077886677 = 1980 (Key 3)*
1970-1976 were Double Digit, 1978-1980 Were single (limited run in early 1980) so a year code of a single zero would be 1980. 1977 i have not found yet, so 1977 is given in 2 examples.
The numbers at the end variate substantiated, so the length of the code is inconsistent (imitated in examples)
This is only based on my own observations, so may not be correct, as i gather more numbers, i will make any updates necessary.
UPDATE: some issues found regarding 1979 & 1980, as known engines from these years seem to all have both a 9 and a 0 in the year vicinity, still trying to work out a pattern.1979 fits as above, 1980 may not have a second 0 after the indicating 0.
FURTHER: Dug out a 1963 Victa Engine (Known, provided with original documentation) and found the 3rd and 4th digits were 63, so above dating system seems to go back further than 1970, This is also seen in Chris's 1969 Corvette!

have you tried contacting the victa factory at moorebank. i deliver office supplies there now and then they have a very nice rotomo on display when you walk in the door, as well as some newer models [including one with flame stickers and flames on the catcher looks cool]and heaps of late model briggs engines
they might help you out with the numbers
Cheers, Emmo

I Emailed them once, but did not get any help, I may try calling Moorbank directly, or dropping in next time I'm up that way.

That would be the way to go. Straight to the source,surely somebody would have the knowledge.After all it would be good to know and able to identify engines with years to get the correct base and engine combination.

I hope they are a bit nicer this time.
Jeffery, you wouldne have the number handy for the MKI VC-160 you are doing up? I'm trying my7 best to test this extensivly, If you could let me know, that would be great.
If I'm right about this, I would expect to see 70 in the 3rd and 4th positions
There are a few slight chances of other results that still fit the pattern, it could be a very late 69, or very early 71, or the 2 digit year code could be in the 2nd & 3rd place or the 4th & 5th.
However, I'm leaning towards 3rd & 4th being 7 & 0, with maybe a 52 or 62 before, and 6 digits after, the first of which should be 0.
So, can I Have your Series 70 MKI Engine Number Jeffery?
Lets see if its 52700XXXXX or 62700XXXXX!

[Censored] you have been looking into it,and yes you are right with the 5270.The number is 527001866 then a fairly big space to a number 1.It looks to me that that one doesn't have anything to do the engine number.As it is a good 8mm away from it.Stop it your scaring me.I was going to use the VC Mustang Mark I engine for the VC-160 Mark II,but with you finding out these number it's now looking like I will have to take the crank out and put that into the other crankcase.That means I would then have to get oil seals then.Now I have to find the other old one I had,to see what numbers it has on it.Can't find the [Censored] thing wasn't where it should be.[Censored] I hate that when you know where you left something and you just can't find it.Hey I found it.This was the VC-160 Mark II engine number 5271014993.

Intrigued by this I checked out my current resto project 125 (thought it was 160) store branded mower and it has "72" as the year code, I would guess this is correct since it has the G3 carb, etc.

Cheers Jeffery, I have a feeling 52 & 62 at the start mean something to the VC-160.
The MKII Serial makes it 71, a year match to the MKII VC-160, It would be the original factory one i would assume.
The numbers often seem mis-aligned across the spaces, I dont think the entire serial is stamped at in one go, maybe the first part at the end of one point in its assembly, then the next part at the fitting of more parts. I have found on one an overlap, where the second gun was so poorly aligned, it took out the last 2 digits of the first code.
And Joe, that sounds about right, Is this the one you have up on Facebook?
Do you have the rest of the number?

Yes I was going to say that the first 2 numbers may have something to do with what type of mower is was.Facebook have I got a picture of a mower on Facebook? I didn't think I did.What other numbers were you after?

I'm starting to spot patterns in the other parts of the code too, so I will see if i can work out anything from those numbers too.
I'm satisfied that the date is part of the code, so far no engine has broken the pattern.
Cheers Ty

I'm planning to go through my mowers soon,and get some numbers of how many and engine numbers.When I do I will let you know what they are, and on some a rough year to see if you can find a pattern.

No worries, That would be great.
I am sure this wont go back to the 50's, but i have trac ed it as far back as 1963, so that gives a good range, I will eventually start looking into the series 80, then one day, i might even look at the power torque.
Cheers Ty
