I'm rebuilding my 261 and want to use a full flow oil filter. I'm trying to drive in the dowel but it won't budge. I used a little heat and a bit of wd40. Still won't drive in. Any secrets to doing this?
Also
What is the torque specs on the rod small end bolts? Not the big end nuts but the bolts holding the wrist pins.
Thanks in advance.

Then either polish it a little, or fabricate another one that can be driven into the passageway without any danger of cracking the block. I have a 261 in storage that I'm planning on building into a "Cadillac 292" and I'm going to tap that hole and screw a bolt into it to block off the passage instead of relying on a drive-in plug.
The wrist pin lock bolts are 3/8-24, which should torque to 35 ft/lbs. or so. One precaution- - - -use something like a long tapered punch held in a vise to support the wrist pin- - - -if you clamp the rod into a vise and torque the bolt, you can twist the I beam section of the rod.

It wouldn't budge when I was being timid when whacking it, so I got a larger hammer and used more muscle. Once it broke free, it drove in easily. I did not use heat. I used a piece of thin wire bent at 90 degrees to gauge the correct depth, but discovered that it really wasn't necessary because you can feel when the dowel bottoms out when it reaches the correct depth. The bent wire is helpful because it lets you know when you are getting close and can start to back off.
It is a bit of a tense process because you are on edge about goofing it up, but it sure feels good when the dowel starts to move.
Good luck,
Matt | | |
