Today I pulled off the oil pump cover to replace the seal and to replace the crank seal. Everything went pretty well except for tearing a gasket and having to get another.
I need help with a couple of things to finish.
1.) Belt tension - Is there an easy way to make sure the belts are the correc tension.
2.) Alternator Belt - I am having some trouble getting the alternator pulled tight to tighten the belt. Is there a trick that makes this easier.
3.) Crankshaft pully nut - I'm supposed to torque it to 116ft.lb. However, when I try, it moves the vehicle. I have it chalked, but it does not seem to help. The trick to loosen the nut by using the starter worked great. Is there a trick to getting it tightened to the right torque.
4.) What should I do before I fire it up to make sure it pumps oil.
Thanks for your help. It will be greatly appreciated.
there is a tool that will meassure belt tension(i have been told it does and doesnt work, dont know where to get one though) a long pry bar and a friend is how ive done my alt belt, u could put ur truck next to a wall maybe? it shouldnt move then
no, just let it idle for a couple min. til it has a chance to build oil pressure.
Torque on the crank nut-- not too important- 'tight' is good enough- I put a breaker bar on it and smack it with a hammer----good enough !
'v' belts should be 'snug' to the point that you should be able to move the long span about an inch-- (if it is too loose it will slip, too tight will put undo wear on the alt. bearing---)
I have never had a problem getting 116 ft. lbs on the crank pulley nut...
Do you have it in 5th gear, high range, parking brake pulled (and adjusted properly)? If so, chalking in unneccessary... The torque required to move the rig in 5th is much more than 116 ft. lbs.
You may also want to pack the oil pump with vaseline as a primer... Helps build oil pressure faster...
I had it in reverse thinking that would be the best. I'll try it in 5th and see what happens. My fiance' will be around as well so she can put her foot on the brake.
I didn't realize that hte V-belts should have an inch of deflection. Thanks for letting me know or I would have made them too tight.
Reverse not only offers more gear reduction, it is easier for it to overcome the parking brake, due to the design inherent in drum brakes. Drums will use the rotation of the wheel (forward) to act as leverage for more braking power... Especially when stopping hard. This is why rigs use airbrakes with drums, rather than disks.
Finished it this morning. The 5th gear trick worked fine. I was able to use a long pry bar to move the alternator and put the desired tension on the belt. Got everything put back in that I took out. Cranked the engine a few times with the ignition disconnected. Connected it up, fire right up and idiot light went off.
Thanks for all your help.
Now on to the next list of things to do.
