Hi all trying to put together a VC-160 Mark II engine,but it seems to have a different bottom of the crankcase.Here are some pictures.




As you can see it has a sleeve over the end.Then a washer over the seal.Then to hold the washer in place in has a plastic bush.Well the plastic bush was destroyed.When I got it apart there was not much of the bush left.What I need to know is where can I get another plastic bush? As from what I can see I think it would leak and the washer will not stay in place without it.
HELP PLEASE!!! I need to put this engine together.
Thanks for any help in trying to track one down.

The only thing is would the oil leak though the seal? I mean other crank cases would have the outside of the oil seal covered by the crankcase.

Was this one of the ones i gave you?

If so, it might be off an auto drive, one of the vc's i scrapped had a regular base, but a green auto drive cowl & Tank.

I assumed the cowl was fitted to replace a broken one on a non-propelled mower, but it could have been a damaged base replaced and converted to non-propelled.

I should have a spare crankcase from the right era that you could have, and you could keep that one aside for a VC-Auto Drive, when you find one!

What's it's serial, if its from an auto drive, i would imagine 73 or 74, as if it's the one i gave you, it had a G3.

No this motor was of the first VC I got.This is the one that I couldn't get apart and so I got the replacement one from you.Engine number 5271014993.I really don't think it would be an auto drive.Didn't they have longer crankshaft?

Hmm, that seems like the original one to me, the 52 at the start seems to be on most MKI 7 MKII VC-160's, and the age is a dead Match to the MKII VC-160.

So if it's not auto drive, I wonder what it is then, does the sleeve seem original?

I would have to say yes,as it looks like you could never get the sleeve off without doing damage to the crankcase. Of-course the sleeve wouldn't survive either.Also on other crankcases the ends curve a little from what I can see here (without the sleeve being off)it appears to be dead straight.From what I can see.

Hmm, I'll have a look through what i have, and see if anything seems the same.

So it's sounds like the bush is not available them?

I Cant say for sure either way, I need to see if it's in any of my parts diagrams first, if it is, then i can get a number for it and find out if it's available.

Would you like me to put aside a S70 MKII Crank Case Just in case, I can make sure its from a VC-160 if possible, so it is original.

Not sure unless it is a 1971 one,as that is what we think it is.

I should be able to give you a 1971 Crankcase, from a 1971 MKII VC-160

I Will have a look tomorrow for you!

Cool that will save all this mucking around with this one.As it seems not much is known about it.

Cant find it in any manual so far!!

That seems to be strange.Could it be from another mower from that time and not a VC?

The numbers do match up for a VC...But that is odd.

However i do recall seing something similar one, i cant remember when though. I have forund a few odd, and un-documented original adaptions on some mowers, I think Victa occasionaly trialed a few idea's but i guess if they didnt take off, they didnt make it into the manuals.

I have a few other odd factory fittings i will put up in the victa section.

Ok I guess for now if you have a 71 then that would get me out of trouble at this stage.

I have found the plastic bush that came from the bottom of the crankcase.Or maybe the remains, I don't know as what it should look like.




Now as you can see it seems to have a lump on one side.Now I don't think it has melted that way by the look of it,it was made that way. In fact I would suspect that it should go all the way around to hold it in place better.


Now here is the bush sitting in where it is suppose to go,but as you can see it doesn't fit properly.I know this may not help in finding a replacement. I just wanted to show roughly what it is I'm looking for.

Ok got my paint today for my VC's.Can't get it in hammer tone.So the closets colour I could find was mint green.I know I know I could properly get it in spray cans,but I'm not going to get it that way.It gets to expensive to do them with spray cans.Spray cans are about 75 to 80% thinners.It also doesn't look as good as a job of a spray gun.After all I thought these mowers are not going to mow any lawns anyway.So I'll just make them a show pony.

So I take it I have everybody stumped on this one now.[Censored] I was hoping somebody knew what it was,and where to get a new one.

Iv'e now checked every scrap of info i have, and nothing gives any info, I have seen this once before, but i cant remember where or when.

If i do find any info, I will let you know.

Ok so what I really need to do is find another 1971 bottom half of the crankcase.Did you say you had one?I'm just not keen on not having anything there as I would think the oil would leak from the outside of the oil seal.

I should have one according to my records, so i will get out there tomorrow arvo and have a dig around.

Cool thanks man.

Are you sure its a bush and not just a melted lump that used to be string or rope???


Ive had a few apart and i havent found a bush like that.

Actually, Jeffery, Now that bob has mentioned that, And i have had a closer look, The one i have found here for you (first four digits 5271) is exactly the same, just without the large sleeve over the end.

Everything else is a match, and there is no plastic bush on mine, the washer with the 2 holes just fits snugly to the shaft when its pressed down into place.

I can assure you it is a bush no melted plastic or string or rope.The washer I have doesn't lock in at all.I will get it out of the create it's in this afternoon and have another look more closely.I let you know what my findings are.

Well, as soon as I can, I will give you the one i have here for you too, and you can see where they are similar, and where they are different.

It is possible, that if you want to keep yours, you could just use the washer from mine (needs no bush) and keep the rest of mine as spare, then you will be able to keep as much original engine as possible!

Just found out a bit more about this.

The sleeve was there on some models as a mesure to prevent the alloy splitting or deforming when the bearing was inserted (from the bottom up on these ones)

The washer seems to come in both bush or no-bush variants, and is a simple dust/grass/debris cover for the bearing, to prevent grass, plastic or rope making it into theactual bearing.

It seems the non-bush, and bush type dust washers are interchangeable.

That's all good news.I see you did add it.Should have looked here first.

Ty I thinking I may have found a different's between Mark I,II and III base's.On the Mark I & 2 where the height adjuster spring attaches to the base.There is just the one pin coming off the base.On the Mark III there is that one pin as well as a guide pin as well.Here let me show you.




As you can see here they have only the one upright pin for the spring.The very dirty one is my original Mark I.The one with the crack on the side.The other one was my first VC the Mark II.




Now these ones have the two pins.Now the one that is still semi green you will remember that is the Mark III that I picked up last weekend.The grey is the one that I got from you.So can you remember if it was a Mark III.I'm thinking from my investigation it was.
