Since i've now decided to rebuild my new engine rather than just clean it up and install, i want to invest in a quality torque wrench as i don't trust the accuracy of the £20 machine mart one i have at the moment.

Going purely off what bill sollis using in the mini engine builder DVD, i've found a Teng tools torque wrench on screwfix: Link

It covers 30-150ft/lb - Will this be suitable for all the nuts and bolts i'll need to torque up? The flywheel is the highest torque setting required at 150ft/lb isn't it? So should be fine on the upper limits. But i noticed in the engine builder DVD, theres a couple of things he torques up which require minimal amount of torque; For example the vernier timing gear adjustment nuts are only 8ft/lb! Pfff! But any fasteners that come under 30ft/lb lower limit of this wrench could just be secured with a ratchet right?

Also i'm trying to find a piston ring compressor like he uses. Found one on ebay but it was about £40! The plier type ones look much better to use than messing with one of the adjustable sleeve type ones where you have to mess with an allen key whilst inserting the pistons. Or are those ones fine and i'm just being fussy?

Anything else special tool wise i might need for an engine rebuild? I have a clutch oil seal tool on my minispares shopping list and also a DTI gauge for cam timing, and i have feeler gauges and things. Have i got everything?

Thanks

For the DTi have a look at chester uk

In the cataloge they have a Dti with magnetic stand in a case for under £20

You can always test the accuracy by hanging some weight off it.

Yeah just found those one there. Thing is its only free postage on orders over £25, so with postage it'll be more than the ones on ebay - Which look exactly the same.

Right well i just converted 200 newtons to Kg's and got: 20.39kgs. That doesn't seem like much at all for that amount of force... Not sure how i convert newton metres into a weight i can understand and measure like kilograms...

To be honest though that sounds like abit of a faff what with the maths (which i'm bad at as you can tell) and messing about working out what objects in my garage weigh exactly 20.39kgs and what to put them in that i cant hang off the wrench...

Infact, thinking about it i've made it sound like much more of a faff than it actually is. I could just do the weight conversion the other way round and find a nice round number to hang off the wrench.

But still, its just i feel the need to buy a quality one. The one i have now just feels so cheap and just wrong to use for such precise jobs if you get what i mean?

Hey Mike I bought myself a Draper one, like the ones which are available from Mini Sport and used that a number of times now, and built a few engines with it and it works great.

The trick with torque wrench's is too not leave them under load when kept in storage, always undo the setting once you have finished with it and putting it back into its case.

I remember a mate of mine who bought a £50 torque wrench and another chap had a £200+ Snap on one, when it came to checking the calibration of them, the cheaper one was spot on whilst the snap on was miles out.....
