Getting the bolts out of the rear suspension, both the ones in the tunnel and the ones in the axle is a PITA for a first timer.
The trick is to tighten down one side well... Then back the other side out almost all the way... and spin it in/out a few times... then tighten that one down well and do the other side.... then take them both out..
As WJL said... an impact gun makes this much easier... still do this back/forth trick and you will have no issues.
Getting the skid back in takes patience and two people if you want to make it easy.
I've had better luck hanging the sled in the back than leaning it on its side to get the skid out.
Bolt wise... On the last couple of QD sleds I've put togehter... I've used ARP 8740 Crome Moly bolts on the bottom and top pulley.
The Quality control on ARP fasteners is some of the best in the industry.
IMO, these are the absolute best bolts you can get for the QuickDrive pulleys.
Pricey... but then you will have some for your friends too.
Just get em...
You will need also some Blue Loctite and brake cleaner spray.
Clean the oil residue from the bolt threads and the threads in the jackshaft and driveshaft with brake cleaner... and let it dry well.... THEN use the blue Loctite.
Lock the brake lever to hold the shafts after you install the belts and snug down the bolts part way
Torque the bolts to 45-47 ft-lbs.
ARP:
8740 CHROME MOLY: Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.
What is the difference between 4130 and 8740 chrome moly?
Both are alloy steels with similar chemistry. The 4130 has only .3% carbon and can’t be hardened as high as 8740, which has .4% carbon. Also, 8740 has about .45% nickel and 4130 has none. Both have moly (most alloy steels have moly). The chromium content of 4130 is slightly higher, .95% instead of .55% (for the 8740). However, 8740 is generally considered to have slightly better toughness due to the nickel.
