OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Victa Lawn Mower Frames Moving Powertorque To Utility Base.

I recently found a Victa utility base in good condition with the big petrol tank. I notice the outer edge bolt hole on the left side is recessed rather than level with the others. Is a spacer required when moving a Powertorque over from a rear catcher model?

I had to fit spacers when moving a full crank motor from a Mayfair base onto a ute.

Hi MF,
If you are talking about the bolt out near the head then yes it will probably need a spacer

They don't use it on the utilities. Just use the 3 holes around the centre.

Hi NormK and bigted,
won't just the three centre holes be unstable? Why does the ute base have the fourth hole used only by the PT then?

MF,
I was going to say leave it out but thought somebody may carry on about it.

Happy to let gravity do abit more of the work. It should be perfectly fine and less hassle.

Hi Mf ,BT and NK

I agree the Power Torque on a Utility base only needs the 3 centre bolts ,I have a few that are not drilled for the
forth hole but never seen 4 bolts used with the utes ,

The long answer would come down to Metal Strength and Stiffness ,If sheet metal is flat it bends easily, to
increase the structural strength the base is pressed into a shape that increases strength without using
thicker materials.

Looking at the Power Torque rear discharge metal base the top engine mounting position on the
base is fairly flat so having the 4th hole will increase the rigidity of the top surface of the base but
looking at the Utility base it has a lot more pressings into it's top engine mounting surface so does
not need the 4th bolt for added support .

I would say the power torque engine creates more torque at a higher RPM, while a 4-stroke engine
creates a higher torque at a lower RPM also the Power Torque being a half crank motor is not as
well balanced as a full crank motor ,these contributing factors would be why the Power Torque
needs the 4 bolts on the rear discharge base.

The Masport base below looks a better shape around the engine mounts than the Victa rear discharge
for strength and stiffness.

Now I get it MW.
The engine itself acts as a brace with the fourth bolt.
Thanks for the run down. Another tidbit for the knowledge bank.
