Engine Build Deutz F6L912: 01 Tappets and camshaft

[towbar]

I got the block, crank and cam back from the shop, all 3 are within new specs so the build begins. My intention is to document it in modular bite size videos, this being the first one for the simple reason that it's much easier to do before the crank gets installed. Hopefully comments will help make the thread and the video complete and useful for others googling for help down the line.

First a question: This engine like the last Deutz, Cummins or Perkins I built has a bushing for the fwd cam journal but no bushing for the others. Anyone know why? The valve springs via the tappets do some of the work holding the camshaft in place but does't the steel-2-steel contact at the other boreholes cause scuffing and wear?

Otherwise here are some of ther points I've thought of covering

• Fanatical examination of the hosting block or other part(s) to make sure that all is in order BEFORE any assembly step.
• Reviewing the appropriate manual entries that describe/guide the intended op.
  
• Cleanliness when bearings/bushing are involved. Oiled or gloved fingers are OK but not bare fingers as the may leave acid on a cam or crank bearing.
  
• Proper placement of any bearing
  
• Liberally PRE-oiling surfaces requiring lubrication in service
• Testing for freedom and ease of movement
  
• Care in installing a cam withOUT knocking lobes against hanging tappets or cam journals against boreholes. In the case of this engine, placing it upside down is best to insert tappets followed by camshaft insertion.

One picture shows the block with some main bores and the fwd cam bushing as weel as one cam borehole. I was surprised by how clean the block came back seeing that they don't do any hot-tanking anynmore. The other pic shows the kleenflo product I like to use as assembly-oil, it sticks better than chainsaw oil so it WILL linger around even if the assembly takes a month to complete.

Any comments on any of the above or on topics not covered but associated to this assembly-step are welcome.

I would use a specialized ‘motor assembly lube’ . That kleen flow is designed as an additive to oil and not a replacement in my opinion

Good point, maybe I won't put it in the video, wouldn't wanna mislead anyone. A pro mechanic suggested it, he uses it because he always has some on hand. I haven't built enough engines to have an opinion.
