CB Rhino case

[RCP Phx]

Are there any other intricacies I should be aware of. I know I already need to change out the oil pick-up tube for a factory one because it comes in at a angle.

Check main bearing oil hole alignment, if they are like mine, you'll need to dremel a bit to line them up with the bearing oil feed grooves.

Ensure oil pump is a tight fit in the case, if it slips in like mine, you need to o-ring the pump body so you don't suck air and foam the oil.

Deburr the inside of the case and smooth it a bit so the oil flows back to the sump easier if you decide to take it that far.

I also agree, I swapped my oil sump tube for the late good OEM VW one.

Make sure to check fit on the pulley you will be using vs the case snout. Depending on pulley size it may seize as clearance is too tight

I bought mine back in summer…

Main bearing holes needed adjustment, but every aluminum case i have had does.

Oil pump fit tight and no issues with pulley.

Nice deck surfaces and crank centerline was perfect

I had to do some grinding on the outside of the case to get my Gene Berg oil sump to fit.

Distributor hold down stud was too short for the MSD distributor I am running. There was BARELY enough thread to double-nut it off. However, just double-nutting it didn't work because the shorter stud was loc-tited in.

I ended up carefully putting a torch on the case around the stud to get the case to loosen its grip and then I was able to remove it using the double-nut technique.

This is probably a non-issue if you're planning to use the stock distributor hold-down clamp and not a thicker one like what comes with the MSD distributor.

So far everything has been good, I've checked the oil port alignment and the bearing index pins. I have removed the fuel pump studs(mines electric), and the short one on the case halve because my intake bolts to it(need longer). Right now I'm trying to get the oil pump intake tube to budge as I run a extended pick-up that won't work with the CB pick-up tube.

As far as the oil pump fitment I will deal with it after I get everything assembled.

The crank pulley seems to measure out ok but again I'll deal with that later. Right now my goal is to mock up the motor to check the deck height, CB did not have a std case so I ordered a +3.5mm deck that they had in stock.

I need to drop the case off at the vw place to get the deck cut and cut for a sand-seal.

I ran into a strange issue today, I was mocking up the case/cylinders to see how much deck to remove to get my clearance where I want it. Both 1 + 3 came in at .160" but 2 + 4 came in at .150", do you think that's even possible?

Yes, it was all a loose fit-up, I think I will just try to relax and try to get off my mind for 48hrs. Monday I will take it to the VW machine shop and tell them what I found and how I did it. Right now the plan is to take .100" off the deck and cut it for a SS.

SS - Sand Seal.

By loose I was reffering to the fact that I was just "setting" them on the case, no studs have been installed yet. I was also trying to see if the numbers matched up to what my VW machinist told me to expect from his experience on the CB +3.5mm cases. He's been buying the + cases also since CB is out of the stock deck cases.

[sled]

that is not an accurate way to measure clearances of any kind, would you measure for bearing clearances with the case halves just pushed together by hand?. Everything must be torqued to spec. also, make sure you inspect the bottoms of the cylinders where they sit against the case, sometimes they have machining burrs or a VERY slight radius on the seat cut, combined with a very sharp case edge can prevent them the cylinders from seating fully. But thats kind of moot if they're just sitting there with zero torque.

If it's the mag case version with the plate welded behind #3 check and make sure the case on that side isn't twisted. I had one that was and cost me a case and crank work.
