comp cams trunion upgrade kit
comp cams trunion upgrade kit Can anyone advise what special tools are needed to install these other than standard sockets and wrenches? Also where can I get the correct torque numbers for bolts on rocker arms and valve covers? Thanks in advance!
There are instructions provided with the kit, it takes most guys about 30-40 minutes to install the upgrade. Very simple!

Best follow the CompCams's video, the other long 11 minutes Ytube video is dangerous, he punched out oem trunion with punch and hammer, then bangs rockers on metal table. His actions looks macho and might look good on TV but clearly, he lacks fineness. His actions indicates that he has no understanding that metal can get distorted when bang around! Never a good idea to bang internal engine components!
Keep in mind, to remove or install trunions, one needs to keep the process inline and perpendicular to avoid distortion. I made my .900 base and .005 drift as recommended by CompCams and used the combinations on my mill. But a drill press will do just fine. I'd found the stock bearings tighter during removal and the new trunion bearing reinstall not so much!
Take your time, its not how fast a person can do it, we are dealing with fitting precision bearings - remember "haste makes waste"!
Good luck!

Verdad Gallardo We can all justify with whatever used for the install - most choose alternatives due to lack of resource!
Keep in mind, the truer it is inline and perpendicular, the less variables we have to deal with and ends up with less complications down the line!

We have a tool similar to LFSADRG's picture, but on my personal vehicles I have used a bench vise or a small arbor press.

I would not consider a bench vise over a arbor press with its rack and pinion!
Even though my machinist bench vise is a high priced Wilton!

i chose the horizontal screw vise over my vertical hydraulic press because of the finer control and feedback I get with the handle. this way I could ensure each bearing went in with the same resistance and there were no issues.
If vise is chosen for the feel, only the precision milling vise offers any sort of parallelism! But the short fall with precision milling vise is the movable portion of the jaw, it is designed to pull work down during the final lock down, which is outstanding for its intended design for secure work hold down! But if this type of vise is used as bearing press and you don't need to lock down, it should be more then sufficient to provide true in line closing and ensure perpendicularity for the bearing fit into the rocker's bore.
Normal bench vise has only acme thread - the good one that is. It doesn't have the machined, fitted, grounded and mated surface to slide on as the milling vise!
Oddly enough, I bought my arbor press just for doing trunion upgrades! Its simple, gives me total control (or at least a better feel of it), and is consistent.

I don't have a business nor a drill press! But I do have a mill and a lathe! I did my trunion upgrade with the mill but I can also do it with the lathe. But the mill is infinitely easier since I don't have to balance the parts other than centering it. Out of the two, mill is my favorite. Besides milling, I used it to compress recycle cans, breaking bead off motorcycle tires and such, terrific mechanical advantage.

At Texas-Speed, your company doesn't have a simple drill press? Arbor press is great, but an drill press can do that plus many other duties!
