I am checking my pushrod/rockerarm geometry and was wondering if a person could use a stock pushrod modified into a adjustable checker?

The only problem with this is I got 3/8" guide plates which I made up the difference with masking tape, but what about the 5/16" ball ends?

If I order 3/8 pushrods by length from my 5/16 checker tool, is there a common pushrod available with 5/16 ball ends?

I have crane/frpp solid rollers and comp 1130 rockers, should I be looking for a 3/8 checker tool or get 3/8 pushrods with 5/16 ball ends? Is this common?
Or am I way off?


Thanks in advance!:confused:

3/8" pushrods have 5/16" ball ends
you can certainly make an adjustable length push rod from a stock unit...
The 3/8" guideplate is of no consequence when checking geometry.

Hope this helps...


:D

That's exactly what I did. Cut about an inch out of the pushrod, threaded both pieces (1/4-20 I think) and slipped in a stick of allthread. Voila.
Same here... took a small chunk out just a couple down, tapped it and used an extra valve cover T-bolt stud I had... all in all, took about 5 minutes...I put some JB Weld on the one end and put it in only a couple turns, I have about 1.25" of adjustability from 8" even to just over 9.25".

The nice thing about the brand name pushrod checkers is they have a built in scale so you know how long it is. If you have a caliper large enough to measure a 9" pushrod, then disregard. I didn't so I spend the $15 bucks on the real checker.
