Pardon the ignorance but what exactly do you do when you 'jig' it? i know how the tab works but i dont understand the jig method

 

Ditto, no need to tab, just a little peening will do.

 

Tabbed mine

using the TST kit, simple wrenching nothing more, and i do sleep better at night now..

You drill and tap a hole in the side of the gear case and install a bolt that blocks the dowel pin from coming out. The jig bolts to the engine to insure the correct angle and depth of the hole.
Advantage to the jig is it's quick and easy.

Jig bolt blocking dowel pin.

 

Dont metal shaving get into the case when you do the jig method?

 

Anyone in have a jig to lone out??

 

Not if you do it right.
What you do is pressurize the crankcase though either the oil fill or dipstick tube with an air compressor (5psi max) or a vacuum cleaner on blow with the blowby tube plugged.

They do over at TDR but the shipping for a jig coming and going usually costs more than it does to buy your own from Harold at rvhvnfn@juno.com or 208 850-8749

tabbed it with the tst kit

 

Tabbed it 3.5 years ago. Cut the tab myself. Pin barely moved, if at all. Also applied some wicking loctite.

 

I just tabbed mine tonight with my kit from tst, holy cow that was easy. The KPD was sticking out maybe 1/16 of an inch.

the worst part was cleaning all the crap off my timing cover.

 

$500 in parts and a large serving of hummble pie.

 

You didnt have an option listed for me. Mine fell out. I had no idea that is what it was. It ran for a good hour before I pulled it apart and found out it was the dowel pin All it did was make racket, and it fell out on the floor when I pulled the timing cover off. It is now tabbed and back in its home with a lesson learned "ill get to it someday soon" may not be soon enough

Works like a champ.

 

Made my own tab and did the job while ago my 97 had 117,000 on it thi pin had never moved but but i do sleep better at night.

 

I had to replace the timing case on mine, which has the "stepped" dowel pin hole... keeps it from walking out in the future. I also put a new dowel pin in the block... installed with red loctite.
