Looking for someone with first hand experience

It would appear that in 2015, Honda changed the part numbers on a few components involved with doing timing belt jobs.

Previously(pre 2015 for J Series motors), the parts numbers were;

• Timing Belt – 14400-RCA-A01
• Water Pump – 19200-RDV-J01
• Hydraulic Tension- 14520-RCA-A01
• Timing Belt Tensioner Pulley – 14510-RCA-A01
• Timing Belt Idler Pulley – 14550-RCA-A01
• Both Cams Seals – 91213-R70-A01
• Front Crank Seal – 91212-R70-A01
• Serpentine Belt - 38920-RCA-A01

Now(post 2015 for J Series motors), the parts numbers are;- 14400-R9P-A01 TIMING BELT
- 91213-R70-A02 CAMSHAFT OIL SEAL X2
- 14520-RCA-A01 TENSIONER
- 19200-RDV-J01 WATER PUMP\
- 91212-5MR-A01 OIL SEAL
- 31110-5G0-A01 SERPINTINE BELT
- 14510-R9P-A01 Timing Belt Tensioner Pulley
- 14550-RCA-A01 Timing Belt Idler Pulley

Why did these part numbers change from the RCA, to the R9P, are the parts different?

From researching online, i have found a few people that say that the pre 2015 part numbers(RCA) will still work fine on the 2015+ vehicles(R9P). Can anyone confirm this?

I would like to

use this kit

use this kit

for a timing belt job on my 2017 TLX but want to be sure these parts will work.

Show me on that page you posted where I can find the answer to my question.

It could be acura going with new part no's due to a new supplier, or purging old part no's from the system.

Rockauto shows the aisin kit fitting all the j-series:

click on the aisin 002 in blue and the fitment guide pops up.

Thank you.. i suspected that may be the reason. Was hoping someone has actually tried using one of the RCA kits on the TLX to confirm.

First, this will be a verbose response, so, if you can follow along, I hope to answer your question.

Second, let's simplify the overall picture, in regards to the mechanical timing belt components.

Since you are posting in the fifth generation 2015-2020 TLX forum section, I assume you have a 5G TLX?

Third, if you look at the fitment chart for the Aisin TKH002 timing belt component kit, below, it fits your 5G TLX as well as the 04-08 3G TL and the 09-14 fourth generation TL.

With that spread in model years, between three generations of TL's, how much change to the components could there be?


I understand you may have a personal preference for installing OEM TB parts into your 5G TLX, and that's great; however, the Aisin TB kit is basically the OEM components, for less money, without paying for the Acura / Honda branding on the box.


With that said, let's get to your OEM TB component part number 'compare & contrast' above.

If you look at the 'prefix' & 'suffix' portion of the part numbers, they stay the same, except for the 'Cam Seals' suffix and the 'alternator drive belts'.

The cam seals, though, have the same 39X53X8 dimensions; however, one is made by (Arai), the other (NOK). Part number 'suffix' change? Perhaps.

The Bando drive belts you listed, 38920-RCA-A01, only has one fitment for the 4G TL (as mentioned); therefore, it would not work on the 15-20 5G TLX like 31110-5G0-A01.

Finally, the majority of any 'changes' in your part numbers above, mainly occur in the three digit alfa-numeric 'root' portion of the part number sequence.

According to the link, I provided above, the 'root' portion only '...tells what kind of car it fits...'

There are always going to be 'variations'; however, as long as the 'prefix' (what the part is) & 'suffix' (tells detail about the part itself) portion are the same they should fit.

This 'logic' especially comes in handy when parts become 'discontinued'.

A 20+ year old 01-03 2G Acura CL-S/TL-S may have a discontinued part; however, a 1998-2002 Honda Accord (lots more were manufactured) may share the same part, because they share the same platform, though the Honda part number 'root' may be different.

I appreciate your response and I apologize if I offended you. I read and understand the link you posted. I understand I can use AISIN parts, I have before in the past. I have also used Gates, and a couple of other manufactures as well. To date, I have done timing belt jobs, oil pump reseals, and valve lash adjustments on 5 j series motors, from J32, to J35 and J37. I but defer again back to my original post;






I have researched before i posted and I have seen a few random people(on Odyssey forums) say they used the older timing belt kits in the newer cars. I am looking for someone with first hand experience to confirm, hopefully with a 5g TLX platform.

In other news.. I posted this same thread on two TLX facebook pages, and also on TLXforums but AcuraZine is way more active in responding, i appreciate that

No worries, I was not offended & you asked a legit question.
I just knew it was not going to be easy to answer the 'why' as to why the manufacturer does these changes (especially in the 'root'), that's the reason for the 'Decoded' link.
I, also, have used many Aisin kits for the last 20+ years.

The last Aisin kit I used was on a 03 CL-S automatic and it replaced the factory one pictured below.
