Re: Mark V Electrical Requirement

I feel that the 25 feet of 12 gauge extension is more than adequate for several reasons. 1. SS recommends 12 gauge wire for a 50 foot extension cord. 2. I ran my Mark v for 40 years using a 50 foot 14 gauge extension cord without any problems. 3. The cord is exposed, lies on the floor, and can be mo...

Re: Mark V Electrical Requirement

My 30 amp circuit has 10 gauge wire (see above first posting). And in spite of the comments to the contrary I never tripped the breaker or caused damage to the motor (it was just serviced and no issues noted) or fried the power switch. So it might just be the older AO Smith motor is very rugged comp...

Just heard from SS Engineering about the Mark V electrical requirements. This is what they said. "When we moved from AO Smith to Emmerson motors, Emmerson required us to list the new electrical requirements for their motor warranty. I truly believe turning the speed down to “D” or slower with e...

Re: Mark V Electrical Requirement

From what i have read and comments made by repair technicians a big issue with ruining a SS motor is frying the start up coil which is not repairable. I don't think a 15 amp breaker will prevent that damage. If you stall your motor and not immediately shut the SS off the 15 amp breaker may save the ...

Re: Mark V Electrical Requirement

My 1983 SS Mark V manual clearly states under Electrical Requirements page 2: "The amperage must be rated high enough to handle the load (in amps) of that motor, plus any other tools or appliances you may have plugged into the same circuit and running at the same time." If you run at 85 pe...

Mark V Electrical Requirement

What are the proper/safe electrical circuit requirements for the Mark V. For 40 years i have followed the SS specified electrical requirements that came with my 1983 Mark V 500 with an AO Smith 1 1/8 HP motor. These are; 15 amp minimum but 20 or 25 amp circuit is better if other equipment is used al...

Thanks for the tip. I broadened my search and found the 10 weight ND oil. The brand is Pure Guard and is sold in one nearby automotive store for $6 a quart.

Re: Mark V Sheave Lubrication

I have found trying to apply graphite from the squeeze container to be hit and miss. I am going to try the 3-1n-1 brand dry lubricant in a squeeze bottle as I don't like keeping limited use aerosol cans since thy loose pressure with most of the product inside. For the sheaves i mentioned that i used...
