The heat will only help you for a second. Rod bolts oil on threads. Last weekend got towed in again and has scored another piston. Most times the bolt is just long enough to grab a couple of threads. Badair is correct, just as lubricant on the threads will affect the torque of the bolt as will re-installing an old fastener with more efficient threads.
Well, miscommunication will make you feel like an ass and humble you. We started Scoring Pistons the next spring and it would be a differant one every time. . The snout should measure within one thousandth from low to high tolerance of the specified diameter from the factory 1. .
. Also be sure to grease the tool threads and the thrust washer to prevent galling. Not at my Autozone anyway. Move to the next rocker arm and repeat the prosses until all 4 cylinders 8 rocker arms have been properly torqued. If they can't hold a half thousandth tolerance, you have chosen the wrong shop to do the work.
What am I missing here. . The puller is installed using the same thread bolts that secured the bottom pulley. Check how far the key sits proud of the crank surface and measure the depth of the keyway in the damper. The vibrations are then transferred to the inner hub of the harmonic balancer where an energy displacing element helps to absorb the vibrations. All Jeeps between 1987 and 2000 should be set to 80 foot-pounds. The balancer needs to be pushed in a long ways and I would not want my crank and bolt doing all of the work with just a few threads doing the starting work.
. It doesnt move a motor at all with the little torque a dampner bolt takes. I prefer to torque them, but I agree that someone who's experienced with his impact wrench can get it close enough. The harmonic balancer's purpose is to reduce engine vibration from the crankshaft's normal operation. Start out with the puller center screw lubricated well. After first 55k 2piston scored. .
Refer to a engine repair manual Chilton's, Hayne's, etc. The one from Autozone isn't like the one I had so my previous post wouldn't make sense. Both times just starts rapidly sucking in and blowing out engine oil when she goes. The wood is used to insulate the damper inner hub from the hammer blows. Let's say for grins that it measured 1. You screw the insert for your crank into the end of the threaded rod of the installation tool. If you don't have a stainless hose clamp large enough to fit around your balancer, unscrew two or three smaller ones and link them together.
Eddie You might have to get a special engine rebuild manual. Installation With threaded damper bolt hole in crank If the crank snout is threaded, the use of a harmonic damper installer is possible. I would much rather have the elastomer type damper. Eddie I will check my service manuals when I get home from work at night and check if it contains the engine torque specs. . . I purchased a grade 8 long bolt as an installation tool since the stock fastner is a torque to yield bolt and once it's been installed, the material is at risk of breaking a second time.
All jets and passages looked fine. After about 4-5 turns on the bolt I tightened the C-clamp a little more. Use the tool and then sell it to me for a discounted price. If you painted your balancer in a rebuild, you can wrap one or two rounds of duct tape around the balancer before clamping. Take that measurement and the damper to your local machine shop and tell them to hone the damper hub to 1. Slide the balancer onto the crankshaft snub over the insert tool.
Around the ring were bolt holes that lined up with the pulley bolt holes in the damper. I just use washers, and the bolt to walk the balancer on. This will damage the threads if over done. So I rented their replacement and returned the one I bought. . .
