Phono cartridge torque wrench


Hi Guys & Gals

Do any of you use a torque wrench when tightening your cartridge to your tonearm or do you just use a regular screwdriver or Allen key? 

Thank you

When shipping stuff pack it tight.

When finding a proper torque, remember this. Clean all the threads, lube the threads or add your type of thread lock (it's a lube if YOU move it's a lock if your not). OR NOT add the lock and use just torque..

Tighten the securements in an even cross pattern until they bottom out. + nothing. That means its just there no torque all. The screws are only touching with NO space between any surfaces, washer, or nuts (if used) I go around 3 - 4 times. THEN (FOR YOU ONLY) and (if they are an alloy or nylons) + 5 degrees (out of 360). That is not very tight, BUT it will never come loose..

They use to call it Zero + torque. All kinds of ways to torque thing PROPERLY.  MC is pretty close. BE light on the torque.. Hinge points, lube and take out the end play, PLUS ZERO.. It pushes the lube away from surfaces..

Reading about lubrications some newbies on this forum can be confused, it’s not necessary to lubricate every moving parts in turntable!

Yes it is.. Cleaning is a type lube. The parts have impregnated anti wear features. CLEANING put the two surfaces together AFTER removing the wear debris, dust and grime.. 

It's 101 first year apprentice stuff. NOT I didn't do it because its hard to clean, BUT I cleaned it because it WORE and left a mess. Moving parts wear, good lube and cleanliness stop a lot of it..

There is a right way and a wrong way.. CLEAN, CLEAN, CLEAN, inspect, repair, lube if needed and assemble with care..
Ok MC Wipe, Wipe, Wipe, and if your on a pure fruit and veggie diet add a couple more WIPES to it. How's that.. LOL

Funny part MC the "Bad guy" turned out to be a great actor too.

"Garrick" (Andrew J. Robinson) on Star Trek, Deep Space 9. He's made a reference or two to the Dirty Harry in the DS9 series, with a look over the shoulder and gaze directly into the camera. All the time with that silly "should I go for it look" and the LAST smirk he ever made in DH.

Man was Clint YOUNG then, So was I.

Just so you know this is the WRONG way to torque. You NEVER put your hand in the middle of the torque wrench and you pull smoothly. NEVER jerk they way this CLOWN is doing it.. This is worst example of torquing I've EVER seen. Start in the middle and it's a cross pattern from bolt head to bolt head..  moving toward the outside of the torqued piece.. Center out..  I'd show him ONE time.. after that "HIT THE ROAD"

It’s done in 2 or 3 steps. about 100 ft lb of torque per round up to 325-350 FPT. It depends if the block and heads have been machined or not.. This is an 855, 16 bolts per head (If I remember right) Early models were 10 per head and 450-500 fpt.

Try 1600 fpt and 100 or so Bolts with a 8 foot torque multiplier. Spreading track on a trench cutter or big bore machine. A day of "Rowing the Boat" Arnold wished he had a back as broad as mine in my day..
No kidding.. 56" chest. steroids work... :-)

No body else wanted the jobs when they set up in Vegas.. I did the CES show just happen to be there EVERY time.. Go figure.. LOL 1600 fpt or 16 ipt there is still a proper way of TORQUING..

i’m glad I have a 50s British roadster

Me too, I’m glad you have it, NOT ME. Did they EVER have a decent gear (GRIND) box?

Rolls Royce, whole different story.. Chauffer please! Farm Girl works for me..

My back hurts thinking about ANY sports car..
You're torquing a securement. Not a cart. Dose that make better sense?

The torque spec is for the actual nut, bolt and washers. The SIZE, number and grade of bolt determined just how secure the pieces are bound together.. Even torque applied over many small increments STOPS distortion of pieces. 

It also to stop permanent warpage from uneven torque.. A pulsating brake peddle is a great example of improper torque methods. Rotors are out of lateral.  I just went through it on my Camry. The guy warped the heck out of the front rotors, putting on 4 new tires. I was smokin.. So was the manager at Les Swab. He new exactly what happened.

He ordered two new rotors and had them on in 45 minutes. I bought the guys a pizza. HE LEARNED. The new kid.. 

I backed up and felt it pulling forward within 30 feet. The peddle was going up and down.. THAT BAD...

They all got a lesson on how to use a torque wrench. Cross pattern in 3 separate increments. Took all of 1 minute per wheel.. As fast as you can hear the CLICK 4-10 times depends on the number of lugs..
