How To Properly Dial Indicate a Bellhousing When Using a T-56 Transmission

Congratulations on purchasing the QuickTime RM-130 Indexing Plate. We designed our index plate to help you properly center and index your QuickTime T56 bellhousing or any other OEM T56 compatible bellhousing.
Due to manufacturing errors that can occur during the engine machining process, line honing, heat cycling and other procedures, it’s possible that your crankshaft centerline and bellhousing bore may be slightly misaligned. While most bellhousings fall well within the allowable limits, which is typically around 5 thousands, it’s always a good practice to check the alignment whenever you install a new or replacement bellhousing on any of your engines.

That was without a doubt the most educational and professionally done bell housing alignment video I have ever watched, and I have watched a lot of them. Great job, thanks for the education!

[@djh9267]

This is beautiful, 1000% better than anything indexing related on KZbin.

[@HolleyPerformance]

Thx, Everything i had found before was too confusing.. Thx J

[@edwardwatt3497]

I'm doing this now on my stroked 6.6L GTO. The plate lined up ok to my Speedmaster scattershield. Concentric is off about .0039 so I ordered a RobbMc Performance Offset dowel kit for $39.00. No drilling No tapping, and no pounding the new ones in. Great video. It really did help alot.

[@johnnyhotrod]

Wouldn’t .0039 be well within spec though?

[@awsgarage5490]

This is great!! I've been struggling with this for a while on my project. Thanks for a clear and concise explanation.

[@deathheadmothman11]

That was super clear and simple to understand. Thank you. I understand now how this works on installation on my tremec 6speed to my 6.0 lq4 engine. I was a bit worried but now it's super simplified. Thank you again!

[@danielesilvaggi]

Thank you out of all the vids I have watched yours is by far the best. Now I can install my Lakewood bell housing with confidence.

[@johnnyhotrod]

Best tutorial I’ve watched on this,thank you!

[@thebandit4393]

Nice helpful video. Thanks for posting.

[@liamhollin8265]

Thanks for this. This is more helpfull than than the tremec official video, which i must say was good, but this one is more detailed. Plus what was helpfull, you high lighted that the mopar products can be abit rougher around the edges(quite literal in this case)as i've got a dodge magnum, i can keep and eye out for this, when mateing it up to the T56. Many thanks once again👍👍👍👍

[@robby9513]

Very nice video and great explanation A+++++

[@shannonsisk]

This is great I had no idea it was a thing

[@davidless57]

I'm a senior mfg engineer for one of the big 3 auto companies. Today we would never let a block get out of our plant with dowel holes out of spec for location, in the event of this, that would be considered a spill and we would contain all the bad and suspect blocks so they would never reach our customers. If a new or modern day block, I would lean more towards a bad bell housing. JM$0.2

[@johnnyhotrod]

I think this is more after an engine is line honed,changing slightly the center of the crank.Also,some aftermarket bell housings are better than others but it has to be checked with the new Tremec tight tolerances.

[@davevandenbranden3309]

Just FYI, the Lakewood offset dowel pins are already marked for the high spot on the back end.

[@ShawnDickens]

Working on LS and show offset pin options, but one is for Ford. I'm sure that won't mess anyone up.

[@frock512]

Awesome video now until I can afford a bell housing I’ll just keep the boost way down with my aluminum unit

[@BlueMonster-co7ib]

Great video. However dont buy the dowel pins in this video. If you order from silver sport transmission. They are marked for the high side. This makes it so much easier. And guess what they are cheaper

[@chrissmith7669]

Working on getting a conversation going from a th350!to a t56

[@kennethalbert4653]

2:50 That's important, ask me how I know...LOL

[@niftyreturns5672]

I am doing manufacturing bellhouging part

[@bowtiejake]

Do you have to run the spacer plate?

[@notagainthishurts]

Have to cut off the right top corner if using with S197 with Coyote Engine.

[@justinw.4222]

Will this plate work for stock 04 gto bellhousing

[@matthewstorm5188]

How much is bellhousing alignment going to help ANYTHING when alignment of the bellhousing and transmission is ignored?

[@SE45CX]

Hi Holley Performance, I'm interested in this topic. Could you tell me what is sound judgement of the bolt strength class of the mounting of the bellhousing to the engine? For an small front wheel drive car with a transaxle would a metric class 8.8 bolts do? Or is class 10.9 more conventional? Class 8.8 will flex more before it breaks right? So 10.9 isn't always best. Obviously my car manufacturer hasn't specified this.

[@jakefriesenjake]

Bellhousing bolts won't flex. Any bolt will do.

[@DanneyTanner]

Why would a guy bolt a plate on the bellhousing first..That plate could be off just as much as the bell housing.

[@Randomgearhead]

so if i have a total runout of .010 from side to side. its only .005 off? in the tremec instructions it just says .005 maximum runout

[@HolleyPerformance]

Correct! thx J

[@TheSmittysGarage]

How do you accomplish these measurements for a transmission without a removable bell housing? I have an adapter plate for a manual trans and the engine dial pins are smaller than the dial pin holes on the plate. I don't think the dial pins are removable on the engine I'm adapting too. What would happen if I installed it as is and the dial pins and holes don't matchi?

[@HolleyPerformance]

Without a removable bellhousing, the adjustment (if any is needed) would have to be done with your adapter plate. The process is the same you just need to use your adapter plate instead of the alignment plate used in the video. The dowel pins should be a snug fit in the holes otherwise you risk the adapter plate moving after it has been installed. It may require some machining or drilling of the adapter plate or to the trans to make the pins fit and work. Thx J

[@mgleason2542]

Quick question.... How do you center the base on the flywheel? It doesn't seem like you spent much time on centering it, just attached it.

[@thebandit4393]

The mag base does not need to be centered.

[@kennethalbert4653]

The distance from the mag base shaft to the locating plate stays the same regardless, that's why it doesn't matter. I can't wrap my head around it either even tho I know it is right :)

[@mikeallen3646]

I bought this and found it not to be trued ( has a slight bow in it ) tried calling their number on the web site and it seams out of service. I will be returning mine

[@johnnyhotrod]

The only thing that confuses me is how you can have two negative numbers at the three and nine o clock positions,unless it isn’t a perfect circle.

[@andy347495]

There is something else that has to be taken into account when using an indicator in this manor... that is, that mag base, rods and everything associated with it is sagging. And, in the process is actually giving you an skewed reading. To test this, attach your indicator to a ridgid piece of steel with the stylus touching it. Zero out the indicator in the upright position then flip the indicator upside, observe the two readings. Ive seen .015 sag with an indicator setup like the one in this video.

[@yafois988]

Great point there yes, I bet this catches most ppl unaware on this.

[@WTRsCamaro]

what dial indicator is that?

[@HolleyPerformance]

Very common dial indicator available at most tool stores.

[@mgleason2542]

Looks like Clockwise Tools DIBR-0055 but might be a slightly different model
