Should I get a 2 piece driveshaft

You might need to cut it down. I replaced the McGaughy flip with the DJM so I'd have some slack because the McGaughy kit jammed the driveshaft all the way in to the transmission.

Really? I have plenty of room on mine.

Yeah, using the DJM kit to shift the axle back a 1/4" gave me 1/4" of slack on the slip yolk. I still can't remove the driveshaft without prying or unbolting some stuff to get the slack needed to decouple it at the rear. Seemed like a recipe for worn seals and bearings with the McGaughy's kit installed. I couldn't even get the axle to match up to the pins on the leaf springs, McGaughy's solution? Use ratchet straps to pull the axle forward until it could all be bolted together. Seems suspect.

Where's you having any problems with the driveshaft being jammed up with the mcgaughys kit?

Take a pic of where the slip yoke goes in to the back of the transmission and I can tell you if you have any slack left, or I can snap a pic when I get home tonight and show you what I mean. McGaughy's will say that you probably won't have any serious problems if you don't have any slack, but you will eventually wear out your rear seal and pinion bearings at a higher rate due to the tension on the driveline.

 

As I said, mine was beyond not having slack and went into the realm of having to force my axle forward with ratchet straps in order to get it mounted back to the leaf springs. I know there are at least two or three other RC guys on here who have had the driveshaft cut down. If you have a reputable driveline shop around that is an option too, have them take an inch or so out of your driveshaft and rebalance it. I didn't have that option where I live so I did the DJM kit which is designed to move the axle back to create the slack taken away from lowering the truck. As my truck sits now, with all my angles dialed in on my driveline I have enough play in my driveline that I should no longer tag the driveshaft into the tranny when the suspension moves.

This is after moving the axle back, amazing how the lengths can vary so much.

That's pretty much what mine looks like with the Belltech flip.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
