URGENT!!

i took out my new acl main race bearings which say they are stock but they are prolly about 1/8" bigger than my stock ones. is this normal or did they package the wrong bearings?

 

update: i have two blocks, one is a 96 and one is a 97, or so its stamped on the block. the mains and journals on the stock 97 are the same size as the acl STD bearings i recieved. so are the main and journal bearings on a 96 h22a4 different than the ones on a 97 h22a4?

 

A4(any 97-01) are 55mm mains, h22a/h23(92-96) are 50mm mains

thrust washers are different as well

 

just get ur block Align Bored(honed) to fit the bearings thats wat i did and especially if ur using arp bolts u'll have to

 

yep, just figured that out. thanks for answering though. after soem diggin the guy on the phone found out the blocks were cast diffferently which to me seems completely idioc that they wouldnt stamp the block different if infact it is different. the guy on the phone didnt have an answer though and said hes calling acl tomorrow.

this day has sucked. Not only do i have the wrong mains and thrust washers I apparently bought a shitty torque wrench and it completely F'ed up my ARP rod bolts. ill post pics of the bolts.

To some it up its been a bad day, atleast im only out the bolts. Wrench was returned and theyre goign to take thebearings back since they labeled the auction wrong.

 

jlude90, you dont happen to have a part number for the bearings and thrust washers i need do you?

 

cant be normal:

 

what block do you have?

if its an A4 or any of the 55mm mains i think they're 1T19570-STD, thats what i was sent(thrust washers), but i'm not 100% sure, but i know they don't work for the 50mm mains. but like i said, i was just sent the wrong ones and they said it was the A4 bearings, so i'm not sure.

i can't help you on the mains

 

the block itself is definately stamped H22A4 and definately has 96 stamped on it as well. I'm prolly just gonna wait to hear back from the guy I bought that from but Ill check out that part number.

 

92-96= H22a1= 50mm mains
97= H22a4= 50mm mains
98-01= H22a4= 55mm mains

 

r u saying that my motor is an impossible motor to have. i keep saying its a 96 h22a4, not an a1. its stamped right on the block.
not being mean i just dont understand why every1 is calling my motor an a1 when it says what it says.

also, ur sizes have to be wrong. the main bearings and thrust washers are larger on my 97 a4 they they are on my 96, the rod bearings are the same.

 

It's very likely that the early 97 blocks were cast at the end of 96, but that would yield 50mm mains. Those journal/bore sizes I posted are well known fact.

 

it seems plausible that the casting date and model date are different, so as vin said, your '96 block is from a '97 Prelude (50mm mains) and then possibly your '97 block is from a '98 (55mm mains) hence the difference.

 

all 92-96 h22/h23 use the same main bearings and thrust bearings. notice how i said 92-96, that means all h22a1 and the 96 h22a4 use the same mains and thrusts
mains: acl part number: 5M1937
thrust: acl part number: 1T1937

all 97+ h22a4 (again notice the years) use the same mains and thrusts, but are different than all 92-96.
mains: acl part number: 5M1957
thrust: acl part number: 1T1957

 

Lot of wrong information in this post. There's no 96 H22a4. Look at my post above for block code and journal size information relating to model years.

 

He says the earlier produced block has larger mains than the later. Regardless of what permutations of production date and model year blocks you use with what he's got, what he's saying is impossible.

 

ok, picture time

 

no, i didnt.

i did miss this at first look though
97= H22a4= 50mm mains

regardless, the acl catalog is apparently confused as well since it give no mention of this.
so what gstrudler has to be the case. im surprised this hasnt been caught yet by the acl guys and their vendors when selling these things.

EDIT:
as rare as thisproblem probably is should this be stuck in the FAQ?

 

ACL's actual catalogue is a bit confusing and has wrong information in it (ie: they list the h22 as 85mm bore). Several distributors distinguish the sizes though as small (50mm) and large (55mm) mains and leave it up to you to know what you need. The mains sizes are in the faq's already.

 

to add to the confusion i remember it being the 97-98 with the 50's?!

 

I must be blind because I just looked and didnt see it. Even if they are it's good to know NOT to trust a catalog. And yea, they can't refund me since the item is opened. So who wants to buy some brand new ACL race main bearings and thrustwashers?

 

Crap....I wish you had this thread one month sooner. I just bought the standard ACL bearings and thrust washers for my H22A4, and guess what.....they were way too huge. I only opened the main bearings and tested one bearing for size. I was able to return paying a 15% restocking fee - I am sorry but that's crap on ACL's part. They need to list that properly.

I know how much that sucks.

 

So you have the bearings for the 55mm mains but need the ones for the 50mm? I might be interested in a set for the 55's; I'm trying to get an h22/f23 stroker build going and the main bearings and thrust washers should work.

 

correct, i no longer need my thrust and mains. lets take this to PM though.

AND DONT TRUST THE CATALOGS!!!!
