Problem installing timing set

[Hoytster]

Had a problem installing my timing set today. This was the set that came with my TFS H/C/I kit (dynaroll set). When I opened the set I noticed it has two allen head screws (instructions said to countersink the thrust plate bolt holes and use these screws so they fit below the surface of the plate) and a bronze washer, both which were not on the stock timing set. Confused, I called Trick Flow the next day and they said they had never heard of having to countersink the thrust plate, which made sense since the bronze washer was not hitting the stock bolts on the thrust plate (the reason for countersinking and using the allen head screws). But they made it sound like I still needed to use the bronze washer.

Anyways, I went to put the timing set on today, with the bronze washer, and after torquing the cam sprocket bolt I could not turn the engine over! So I removed the cam sprocket bolt and pulled the set back off. It appeared the bronze washer was too thick and was being squashed between the timing set and the thrust plate. So I took the bronze washer off and installed the timing set without it and the engine turns over just fine. I pulled on the cam sprocket to see if I had any play and I have a VERY slight amount of play (about .0004), which should be fine.

I'm just not very confident that I put everything together right, especially since there was nothing in the instructions that said you shouldn't use the bronze washer for certain applications. The only thing I know is I can't use the washer that came with the set because it is just a little to thick and will hold the engine back from turning.

Here are some pics to make what I'm talking about a little clearer (maybe).

Here's the bronze washer included with the set:

Here's the stock timing set with some explanations:

I've seen that happen when using one of those bronze washer thingies.

If you put some axle grease on it, that will keep it snug in place while you put it all together.

I think the actual bronze washer is too thick, or just plain not suppose to be used with my engine (you would know better than me though). The first time I put the bronze washer in, it did bind and I had to back off and reset it. But even after I reset it the washer was being clamped HARD to the thrust plate allowing no camshaft play. When I take the washer off and reinstall the timing set everything goes together well and I get about .003-.004 of play. When you set the washer on the timing gear, it is more than 1/64" higher then the second ring. The second ring on the new timing set is the same height as the second ring on the stock timing set, hence why the washer gets clamped to the thrust plate.

That's why I'm thinking the washer is either wrong or not suppose to be used.

Hmmm .... interesting. Never heard of this problem coming up. Any of you other TFS guys run into this problem on the install?

FYI, when I talked to the guy at Trick Flow he said they had a backorder on the timing sets two months ago and had just received a large shipment last month (about when I ordered my kit). I wonder if the company that makes the sets (SG Gear) changed the design or even mis-packaged the instructions? The few people I chatted with about this kit said they never got the instructions I did...

My Rollmaster I got from FTI had one...But it was only .030 max thick or so.
Somethings wack...I would think .003-.004 would be just fine...
Might be it fits other models as well and not needed in your case??

Well I called Trick Flow again today and described my problem. The guy talked to a couple other people and basically came back and told me the way I have it installed should be correct. He stated as long as I'm getting the correct endplay then I should be fine. He also said dynaroll was incorrect in telling people to countersink their thrust plate and to NEVER do this.

Wish I would be more confident in that way I have it installed...

I can't help with your problem, but I can add some info on the countersinking subject. When I had problems installing my Rollmaster timing set, Ed C. reccommended I use allen head bolts and countersink the thrust plate. The reason for this is I'm using the Rollmaster with the torrington bearing and it's too wide to fit with the stock bolts and the allen bolts are too tall. I just ended up grinding off the top and sides of the allen bolts to make it fit.

Thanks for that input.

Btw, SWEET CAR!!!!

i installed a coyles on my 347 and it didnt have one of these, i just put it on the way the stock one goes on with the thrust plate, what exactly does that spacer do?

Supposed to cut down on the end play

Or completely eliminate it in my case
