dial torque wrench needed

[jakwoo39]

is there anybody in the dunedin area that may be willing to lend me their dial torque wrench so i can set the bearing preload in my new diffs

or maby know of a cheap one for sale as i will only use it for a few days

You can use string and a weight to get the same result if you can't find a torque wrench. Your Toyota manual might suggest this method and show you how to do it.

i dont have an owners manual and my max ellerys manual doesnt say
and if i use the weight how do i convert a weight measurement to a torque measurement
and will this be accurate enough?

[SMOKEY]

OK I take it you are talking about the pinion preload as the side gears are set using a dial gauge, the measurement is initially set up as 1.9 to 2.5 nm and then the final should be plus .5 nm. this to make it easy for me is to convert to ft lbs = 2.5 call it 3 because being a 4x4 to much is better than to little. Have you got a spring balance ------ for weighing fish ?????. if not they are cheap. Get a socket set bar mark along 1 ft and attach your spring balance , apply 3lb pull to it and if the pinion just starts to turn you have got 3 ft lbs of pre load, the old mechanics like me never measure , you get the feel for it after you have done a few hundred. You will find that being 4X4 and being hard on diffs the way they are driven I usually double the given preloads. go on put me out of a job,

GO FOR IT,

ive been in the same boat for a while trying to track down a dial torque wrench but not cheap,700 the lowest price so far,in saying that diff shop quoted me 700 to do 1 diff so itll easily pay itself off.i could go down the path of by fell but unfortunately im usually over tightening things.any body found something similar to this but in the right range?

Just remember that some torque measurements are in inch lbs and some are in foot lbs ( pinion preload is usually in inch lbs )

Ha Ha Kev, another old spanner man , your spot on with inch pounds because most if not all torque wrenches would not be accurate below 15 ft lbs. The pre loads are very little that is why they are checked with out the oil seal fitted because the friction of the oil seal would be more than the load on the bearings, if you can just feel resistance you are probably close to the pre load. By the way Kev, I will be up your way in two weeks will try and call in for a drink ,

You could use one of these, you can get them from some bike shops for around $100

mhm,that's not a bad option,could see it working and at a lot better price.might have to ring around a bit and see what i can find

I got one of those for doing the suzki diffs, $105.52 incl postage from bicycle.co.nz, might be worth trying torpedo7, they're usually cheapest but it isn't listed on their website atm. Pity I'm in the wrong island, I won't be doing the R&P swap for another month or so...

so my diff requires 12-15 inch pounds
so does that mean i go out 1 inch on my spanner then apple 12lbs.
also i have to do mine with seal in place because i have a crush sleve so once its in thats it

[SMOKEY]

jakwoo39, what sort of diff o/haul have you done ?, if you have completed a complete strip and rebuild there are steps that should have been completed before you get to the final step of checking the bearing preload of the backlash between the drive pinion and the crownwheel, this is done with the seal fitted and to make sure you don't collapse the collapsible spacer to much. Your way of measuring in lbs is correct but my calculations = about 26 in lbs, I think you will get a better feel for it if you go out to ft lbs.
