distributor gear destroyed

[FSJK]

As far as I know, there are only 2 or 3 companies that make them.

I thought the BJ's & Bulltear ones were both made by Crown, and although they had consistency problems in the past, Crown worked with Bulltear to have a tool made to measure & verify each cover was to OE spec.

There shouldn't be any quality issues with those anymore unless it was an old stock, which should have been removed & scrapped.

When I installed the cover I did use the alignment pins and there was a gasket under the distributor. The cover that I replaced was a cover that the PO had replaced when he had the motor rebuilt years ago. I haven't gotten it all apart yet but looking down the hole the cam gear looks ok.

Has anyong usedanything like JB Weld tofix cracks in covers? Its cracked under the water pump between the pump and cam. Would it be safe to try somthing like that to reuse the old cover

...and if you don't use the gasket under the base of the distributor

Eek! I just swapped distributors today and forgot to even look for the gasket. Thanks for reminding me. I need to check that before I forget and fire up the engine.

Has anyone use Omix-ADA distributor drive gear set Part # 17423.03

[FSJunkie]

I don't need proof of the aftermarket timing covers being crap. Just the rumor is enough to make me stay far away from them.

I've been running a standard Bulltear aluminum cover for 10,000 miles now without an issue, and that's good enough for me. If I had to to it over again, I'd go with their nickel plated cover with an oil pump midplate, the relieved gears, enlarged passages, and a double roller timing chain. best easy durability mods one can do.

NO Omix gears!

I recommend MSD 8005 and 8007. I use them. OR - pony up for a matched set from Bulltear.

[serehill]

no & NO

You can not Jb weld the cover. I have never used OMIX & got talked out of them a while back. I have no proof they are bad But I'm not finding out.
I'm using MSD gears.

You really need to find out what caused it. I am seeing nothing but speculation as to what happened no facts. I twould be very interesting if the cam ger is in tact.

had the same thing happen 3 days before going to the jeep safari
---new msd dizzy oem cam gear bad juu juu

[letank]

I've owned a LOT of Jeeps.

I've mixed and matched OEM covers/distributors/gears many many times and NEVER had a set of gears get munched.

It's been well documented that some replacement covers are junk, and why I would never use one.

Same here, I am even missing a dowel on the 74 for about 150Kmiles, and no distributor gasket, even swaped an HEI from another wagoneer, about 40Kmiles ago.

I needed a timing cover this past summer. Went to the wrecking yard and found one for $ 60. Can't beat OE.

[Mars]

I popped for the gears from bulltear.. IF THEY EVER ARRIVE!! lol

[ROK360]

I had the same thing happen to me a few years ago, actually bought the timing cover - a Crown part - locally here in Oz from one of the Jeep parts suppliers. (They have shut their doors now.)

I read about the matched gears and the timing covers from Bulltear. In the end I got an OEM one from an old guy here in Oz that deals in Rambler stuff. He modifies the cover and it has stainless liners for the water surfaces.

Haven't had any issues since.

Well I have a set of Bulltear gears on order, going to install them and the old cover, check how the distributor fits and then the new cover and do the same, hopefully all will go well. There has to be somthing to make it eat the gears that fast.

Pretty sure all the timing covers (Bulltear, BJ's ...) all start life in the same place. Bulltear checks them for the correct dowel pin to dizzy hole relationship, and returns the ones that don't make the cut.
I don't think any other vendor checks the covers.
OE is the way to go if you can, mix and match and it all worked and played
nice together, the aftermarket is a crap shoot, with cam gears, cams, dizzy gears, front covers, timing gears ... have all had reported miss-matches that end up eating
the cam and dizzy gears, any one of the above can and will leave you sitting on the side of the road if wrong.
All the OE stuff swapped around just fine, but throw one bad part in the mix and you are hosed.

When you replaced your timing cover did you also install a new timing set? If you did you may want to verify your oil passage from the cam (backside of cam timing chain sprocket) to the cam gear that oils the distributor gear.

In fact, a quick check of everything before you pull your timing cover off, would be to remove your fuel pump and distributor, and then prime the oil pump while you manually rotate the engine to verify you have oil coming off your cam gear. You can look through the fuel pump opening on the timing cover to verify oil is dripping off the cam gear.
