Title: Bottom end reassembly
Post by: wolfsburged on October 06, 2010, 07:10:22 pm: Hoping to beging putting the TD back together soon so a question seperate from the build thread.

This will be my first real rebuild, so any tips or tricks appreciated. Have assembly lube!

I opted for ARP hardware for mains, rods, and head bolts. I recall seeing posts about different torque specs for the ARP head bolts when using the ARP supplied lube. Do I need to do anything special on any of these three areas or just stick to the Bentley?

Thanks,
Bill

Except the head bolts. If you have the VW new ones I have no clue. The Cogsworth old ones that everyone is using before. Here is a thread that I will link that has "zukgod1 head torquing procedure" I went to 105lbs with my head bolts. I have an MLS 1.9L HG and wanted to make sure it was crushed good.

I turned my block heater on 2 times and let cool each time before torquing. Took a couple days, but I don't have any issues in 800 plus miles.

http://www.vwdiesel.net/forum/index.php?topic=21182.15 about mid page you'll see zuk's procedure. I did it very similar, but instead of running the engine I used a block heater so no combustion forces were on the HG :D

Now that makes sense! Thanks.

Post by: wolfsburged on October 07, 2010, 05:59:24 am: I have the new ARP VW Diesel bolts. I guess not a lot of real world experience on them yet?

Was going to swap to the TDI timing sprocket, but my machinist did not think it a wise choice to modify the end of the crank, and starting to loose serious amounts of free time to work, so I will be going with a new 1.6TD sprocket. Sticking with a v-belt arrangement so I imagine this will be fine.

Good idea about using the block heater to heat cycle the thing. I will be installing a new block heater as well.
