Vandejo get’s some attention | Repairing the flex plate cont’d

Well, I finally managed to get a little bit of work done on Vandejo today. I installed the replacement flex plate and torqued it down. Crank it up a notch on the torque wrench for this one. Bentley calls for 65 foot pounds of torque on the 5 triple square bolts holding it to the crank shaft. This is for a ’74 automatic transmission with a ’78 2.0 FI engine.
After doing that, I thought about the loc tite. Now, I already knew from the start that I was going to put some loc tite on the bolts going from the flex plate to the torque converter. These were the ones that backed out on us on our trip to the Sand Dunes, even though I triple checked that they were torqued to spec. But there more I thought about it, the more I wondered if I should put loc tite on those 5 bolts holding the flex plate to the crank shaft. I could see where putting too much on could be negative in the long wrong, but what about just a dab? So I posted to the mailing list to get some opinions, and tucked the engine back in under the bus for the night until I get some responses.

  1. The surveys are in! Most opted for blue loctite, but all agreed that something should be used. I went with red loctite on the bolts from the flex plate to the crank, and will use blue loctite from the flex plate to the torque converter. The thought here is that I could possibly perform maintenance on the bolts going to the torque converter, so I want to be able to get them out a little easier. The bolts going to the crank though, I’ll have to drop the engine anyway to get to them, so it’s going to be a chore anyways. Why not make sure they don’t back out.
