Tech:Engine/K Series/Camshaft

2009-07-09T09:41:30Z

Felix: /* Camshaft */

== Camshaft ==

There are two stock camshaft profiles. The first is found in Sprinter motors with twincarbs (K-B, 3K-B), it's an 18-58 (256 degrees). The second is found in all other K motors with solid lifters, and is a 16-50 (246 degrees) with 0.338" intake valve lift and 0.356" exhaust valve lift.

The camshaft is modified by grinding the lobes, you don't have to buy a new cam when you want different valve openings.

There are many, many aftermarket cam grinds available for these motors. Here are some popular ones:

'''Tighe 112:''' 20-60, 260 degrees, 0.423" valvelift (best for 3K engine, most torque in 4k/5k, 6500rpm peak power)

'''Tighe 104:''' 25-65, 270 degrees, 0.423" valvelift (best for powerful 4K/5K, alot of torque, 7500rpm peak power)

'''Wade 169x:''' 30-70, 280 degrees, 0.405" valvelift (custom cam in Doug's rally car, slightly more top end, slightly less torque than above)

'''Camtech 609:''' 33-64/72-32, 277/284 degrees, 0.435" valvelift (this is Stewart's cam, peak power 8000+rpm)

'''Waggott 605:''' 21-61/63-19, 262 degrees, 0.347"/0.343" valvelift (stage 1 grind, Alex uses this one, peak power 6500rpm)

Note: Tighe 104 cam does not appear to have an aggressive/lumpy idle (Camshaft supplied, They charge you $110 to grind a standard cam to spec) - Justin...

== Camshaft Replacement for K Series motors. ==

When you do the cam,

'''Degrease engine before hand.'''

I always set the engine with cylinder 1 on TDC on the firing stroke.
Set the engine with the timing mark on the pulley on the TDC mark.
Look at the cap note where no1 lead goes. Should be inline with the
second spark plug hole in the head. Pull off the cap, if the rotor
button points to where no1 lead was your set. If it points to four,
turn the engine over 360degrees.

Once you have the radiator out loosen the crank pully bolt before you
rip into the engine. A bit of compression helps here, put in gear
with the handbrake on. Get a big spanner or breaker bar and your
favourite big hammer, and belt the shit out of it until it undoes.
Cheaper than an impact wrench :) Watch the spanner or socket doesn't
slip, or you may strip the head.

Most of the time you can pry the crank pulley off with a couple of
big flatheads. Some pull off, usually ones out of the car. :( A
couple of long bolts through the 2 threaded holes in the pulley will
move a stubborn one.

Open the engine up, take out the rocker setup remove bolts outside
in, remove pushrods and fishout the lifters, maintaining the order.
About this time you will be cursing if you haven't maintained
frequent oil changes.

raise the car on stands and drop the engine mounts on the xmember and
raise the engine for working room. I'd loosen right off the back 3 or
so sump nuts on each side (may need to loosen off block to gearbox
strengthening brackets if fitted for access), and take off all the
nuts forward of this. Carefully drop the front of the sump, pull off
the timing cover, remove the tensioner, undo the cam gear, remove the
gear and screw the bolt back into the cam a few turns. Remove the cam
thrustbearing and carefully slide out the cam.

Lube up the lobes of the cam with camlube or moly grease. Slide in
the new cam, reassemble, double checking the timing marks. Before
you put the timing cover back on, remove the studs for the
sump attachment and replace with bolts. Make things easier next time,
as you dont need to drop the sump anywhere near as much.

Use locktite no3 non hardening aviation goop, and give the sump
gasket a good coating. Tighten the sump nuts up evenly. If you do it
right it will never leak.

No big deal to put back together, just watch distrubutor timing.
Sometimes the oil pumpdrive can throw you out a tooth when you drop
in the dizzy if not aligned properly.

Before you start it, pull the coil lead and crank over to build up
oil pressure. Connect coil lead and start. Run at fast idle over 2000
rpm for half an hour to break in cam. Recheck valve clearances after
a few days running.

It's not too bad a job. If the engine is clean and you raise
everything for access it makes things a lot smoother.

Tech:Engine/K Series/5K-C/5K Hydraulic To Solid Lifter Conversion

2009-05-11T03:14:45Z

Felix:

== 5K Hydraulic To Solid Lifter Conversion ==

Worried that your 5K hydraulic lifters won't be any good at high RPM? Many people consider this to be the biggest letdown of the 5K-C engine - other's say that the lifters are fine to 8000+ RPM. It is pretty much up to you, but many people still advise doing this conversion. (Here we will discuss how to convert Hydraulic Lifters back to Solid Lifters in a 5K-C).

'''''Easiest Solution;'''''

Well, Luckily for you, We have some very kind people on rollaclub who decided to share some little-known information that the 5K-C actually did come from factory in one vehicle with factory solid lifters! This means that if you can find this part, You won't have to mess around - just '''"bolt it on"''' It was fitted to a Toyota KM36RV-JR Liteace Van with a Toyota Part Number of ''13751-61020-'' this part number cross references to a 3F Landcruiser, So if you can find a 3F Landcruiser engine you'll have one and a half sets.

This part is listed on the Toyota EPC (Electronic Parts Catalogue). Here is a screenshot of the EPC page for the 5K Solid Lifter :

[[Image:5ksolids.jpg]]

''Many thanks go to Chris and Tony Scott for their research and extensive knowledge that they contributed to finding this part number''

'''''Other Solutions;'''''

''Xany's KE55 5K Solid Lifters;''

Ok basically the way we did it was trial and error, As I cant remember the actual measurements of the 5K hydro lifter. Find yourself some calipers and if you have a spare 5K lifter out of the block, measure the length and diameter of the lifter. Once you have that you can bascically just cross reference the measurements with a chev lifter of the same. Most of the chev lifters we found were solids. Once you have found the lifter that matches you'll then need to try and find some pushrods to fit. As I used a 3K head the pushrods had to be changed from ball - ball ends to ball and cup. I'd heard somewhere that A12 Datsun pushrods are a one peice ball and cup pushrod. So I found some of them and they actually did fit nicely....The only other thing I changed was the rocker gear as the 5K item isnt adjustable because of the hydraulic lifters. I changed to the 4K rocker gear, just remember though that there is 2 different 4K rocker gears, one with long posts and one with short.

'''Note: This will not work with an original 5K shallow combustion chamber head. You have to be running a taller head from a flat top piston motor (ie. 3k bigport), otherwise the A12 pushrods will be too long.''' -Felix

* Looking for articles by anyone who has done it the hard way...
