You are right there Max, all the stuff I have here will probably go to scrap, just not worth the effort

Yes Bumps that bearing must fit the 125 cc and earlier 160 cc Victa, if yours is the later crank I would just use a second hand crank
that's has a good big end or swap a PT alloy rod and bearing. I wouldn't even get $40. these day for a serviced Victa PT mower.

I've seen Victa 2 strokes advertised for 2 years for $60. and they still can't sell them.

Been a while since I have needed to source bearings for obsolete machinery but suggest you take whatever bits you have to a bearings supply joint, and if they don't seem interested try another place.

One thing I discovered decades ago is that most bearing manufacturers may only make so-called sealed bearings and the part number may differ from the unsealed original but you can just get a sharp knife or pick and remove the seal/s.

Plenty of motors here if you want to grab a crank out of one

Dear Max thx for your rapid reply but I cannot possibly see how the proposed bearing (HK1616F) would fit my application?
1. Bearing OD from your literature is quoted at 22 mm whilst the bore size on my con-rod is 27.61 mm - see attached photo
IE. Bearing OD is 4.4 mm undersize.
Q: Are you implying that I need to machine a sleeve and fit it to the con-rod big end bore to take up the gap?
2. Additionally, bearing diameter under the rollers from your literature is quoted at 16 mm whilst my crankpin diameter is 19.63 mm - see attached photo.
IE. Bearing is 3.6 mm undersize so the crank pin cant slide under the rollers.
Unless I'm missing something, I see cannot how the HK 1616F bearing would work in the big end application.
Any other ideas would be appreciated.

Hi Bumps ,

You can use HK1616F - NTN or just get an old power torque motor and use the power torque alloy conrod and big end bearing.

I did see one in Aus for $11. but was just one of the first ones I looked at. https://au.rs-online.com/web/p/roller-bearings/0454749

Try your local bearing shop or just google online sales for HK1616F - NTN

Cheers
Max.

Can anyone suggest a supplier for a new big end bearing for VC 160 2-stroke late 1970's?
The size data is shown on the accompanying photos.
I've looked everywhere but the only bearing that I can find is a fully encapsulated roller bearing which seems quite different to the separate roller system that I found once I slit the crank shaft.

KIND REGARDS TO ALL

Radial shaft seals and wheel dust seals are often easier to source through an tbs industrial bearings and seals supplier than through mower dealers, especially for older Rover, MTD, and Victa models where the original parts were bundled with complete wheel assemblies. If you can measure the axle size, outer diameter, and thickness accurately, most Railway bearing shops can usually match a generic seal that fits properly without needing to modify or grind it down.

Yes, those are generally called radial shaft seals or sometimes wheel dust seals, and most bearing supply shops can usually match them if you bring the old one in and measure the ID, OD, and width accurately with calipers. A lot of mower manufacturers never sold them separately because they were considered part of the wheel assembly, which is why they can be frustrating to source individually. Since the Victa and Rover/MTD versions differ slightly in OD and thickness, your best bet may actually be an industrial seal supplier rather than mower parts dealers, because they can often cross-match generic seals that fit the axle and bearings correctly without needing to grind them down.

Thx Norm, appreciate the warm reply.
Guess I should have waited for a reply from Forum members before rushing to make the purchase.
