Thanks for your replies.

Thanks Tom, you are right => measured 300 LBS over the nose at 25.05mm = 136kg on my engine and on Logmech's site they rate the Oteva 75SC duals at 140kg @25.4 mm. Smile

Hi Guys,

I have a Proform valve spring pressure tester which is scaled in PSI and Kg/cm2.

Testing my Oteva 75 SC dual springs I find 100 PSI at installed height and 300 PSI at full lift. The equ ...

Well, lashcaps were from Berg.

Some only 2 lobes of the cam showed a damage.

I will use the scat caps that were in the box of my 1.4 scat rockers for this rebuild as I hope they match metal har ...

Perhaps a good time to ask why my 1.4 cb rockers have been damaged so much by the lashcaps I found concave when dismantling the engine.

Hi txoval. During the break in the revs were maintained at 2500 rpm and I set the idle at 1200-1400 rpm afterwards but it did not prevent damage to the cam. Luckily the TP were not damaged

Hi,

The idea behind 3.5mm is longevity. I have titanium retainers, TP lifters, Aluminium tapered pushrods. Therefore I think I need less spring pressure. I know not everyone agreees with GB's state ...

I have played with various shims and with 1.67mm shims after having shaved 3.5mm from the rocker stands I get this, what do you think ?

I suspect that they are the same size than the ones used by Westfalia. The torsion bar tube measures 89mm to which you add about 40mm for the thickness of the hitch. You end up with a minimum length o ...

Hi,

Thanks for your reply 67Rustavenger

I am using light springs that I purchased from Aircooled.net but have never thought about doing the geometry heads off the engine. Good Idea.

I am currently doing my geometry with 1.4 Scat rockers on a 2276 with 043 heads.

Thanks for your comments.

I actually do torque them to specs but never checked if the tool was well surfaced.

As I have measured 0.995mm with a depth micrometer for piston #3 and 1.05-1.08-1.13 ...

Hi Guys,

I am rebuilding my 2276 and have a perhaps a silly question.

I read that some people tighten the deck-height tool to 3.2 Nm to ensure that measurements are 100% accurate and some don't. ...
