TD 9 WQrong piston siZe!! What now--

Well, I pulled the piston in number 4 cylinder -ugh. The top piston groove was chewed well, with bits of ring imbedded in the top of course. However, the cylinder wall -sleeve- is in excellent shape -not a scratch -puzzle???? Anyway, after pulling the piston I was going to install another piston from a TD 9. That piston would not fit into the 4th cylinder. I measured the piston across the top- and it measured 4 and 7/16, okay. I measured the piston I had removed, and it measured 4 and 3/16 problem. What the --- do I do now? Does anyone know where I can pick up a piston -five ring, TD 9 with the measurement of 4 and 3/16??
Why would there be a narrower sleeve?? And if someone put a narrower sleeve in, why, doesn't make sense. Perhaps some one here has a sound explanation, and where I may purchase a piston with that measyoo.
thanx in advance
Love my TD 9 - Td 9
 
What about the other three cylinders? there were two four cylinder diesels used, before 1956 the 5.5lt was used and after a 5.7lt, the 5.5 was 4 1/4" bore and the 5.7 4 1/2", so you got a 5.5lt engine and a 5.7lt piston,you need to get a 5.5lt piston

PS sorry I can't help on a source as I am on the side of the pond but when I do need odd pistons an engine rebuilding shop usually knows where to get things for the older engines.
 
F P SMITH in California might sell you new pistons.
I think the early 9s had a 335 engine & later on they had a 350.

First what you say makes sense. AJ, I just measured this morning, and the one engines' piston's measures 4 and 15/32; the other engine with bad piston measures 4 and 12/32. The cylinders ID, on one engine measures 4 and 17/32; the engine with the bad piston measures 13/32. So, I must find the correct piston -4 and 12/32
Anyone know?
Oh, AJ; all cylinders are the same, and thank you much.
 
You must have a 335 engine with a standard bore, piston size 4.400. Also they used a overbore with thin wall sleeves with a 4.500 piston. Other engine has the overbore or its a standard piston from a 350 engine.
 
Clean off the top of one of the others there might be some numbers stamped on them,the guys on Red Power will know where you can get a piston.

Thanx A J. The bore I need is 4 and 1/4. I have learned from you and a few that they made two; 4 and 1/4 and 4 and 1/2. Most all engines 334.5 have the 4 and 1/2. I think it will difficult to find a 4 and 1/4. For this reason I think previous owner put a ring on the piston and went with it. I will put a photo of the piston up soon. Thanx again.
 
You sure its a TD-9? The D-335 all came with a inside sleeve diameter of 4.3990 to 4.4010.
Later replacement sleeve and piston sets were sold for a D-335 engines and the sleeve ID measured 4.4990 to 4.5010.
If you have the original bore cast iron piston and the more than one type original bore aluminum piston that was used? Without a piston number its hard to match the other 3 without comparing.
 
(quoted from post at 10:31:39 03/12/15) I remembered you had posted pictures of the piston and had a look,the part # is stamped on it 8080DBR, Googled it and Machinery Trader are showing an ad with three pistons of that #, the contact details are at the link below,make sure its the right one.

Contacted the person AJ. He has three pistons and they are what I need.
The smaller piston. He is looking for some rings. I don't understand; why some people keep stating D335 engine. I wondering if they are talking about an engine in the 60', or 70's on? I know the only engine for TD 9 up to 1956 was a 334.5 cu. in. I don't understand why there was a 334.5 with a one size sleeve and having the same engine with a thicker sleeve. Like you say; 5,5 and a 5.7 Where is it a person could read about.

Would you give where I may find more information on your statement? Thanx I wish to understand
 
This is IH numbers and parts. If you have a 4 cylinder engine the 4.4 bore listed beside the D-335 was original bore. over to right is the 4.5 overbore with 4.5 part numbers. These were thinner wall sleeves that fit in the D-335 engine block. Since later on thin wall sleeve and piston kits is mostly all IH sold the original bore parts are harder to find.
Need a parts book to see the different pistons used from start to stop of the D-335 engines.
If I remember correct the engine size and serial number should be stamped in at injection pump side of block near front and just bellow the head.

(quoted from post at 03:49:52 03/13/15) The 334.5CI was commonly called the D335 5.5 Lts the 350CI was the D350 5.7Lts,looking around to locate a set of rings the search brought up Hastings application list,the ring set for the D335 is 2C7754 [Hastings #] there is only one ring set listed.

Thanx AJ As I have read; The 334.5 (D335) was made from the start -40's- to 1956. At that year the D350 was issued.
Now, the one engine I have -perhaps both- are made in the 40's.
So, how could one engine have the thicker sleeve, and the other engine have a thinner sleeve? To say the thinner sleeve is associated with the D350 is not true. For my one engine with 4.5 bore is made in the early 40's. The other engine is newer -late 40's. The casting number of both heads is 8101; which, is in the 40's. Now, if we are saying that IH made the D335 with different sleeves, then that explains it. However, It does not include the D350; which, was introduced in 1956.

Now, if we are saying that IH made the D335 with different sleeves, then that explains it. However, It does not include the D350; which, was introduced in 1956. I have observed the sheet you have submitted, and I see that after TD 9 there is 91 series. As I understand; 91 series is upward of the 1960's. My Td 9's are both in the 40's. Now, we have a difference. Is this not true? Actually, the D350 has 4. 5/8 bore.
 
Both size sleeves that fit a D-335 are the same OD. One that uses the 4.5 piston is a thinner sleeve. Makes the 335 a 350 CI. 4.5 sleeve in a D-350 is a bigger OD than a D-335. Thin sleeve for a D-350 block is the same OD as a 4.5 D-350 but has a 4-5/8 bore to make 370 CI.
I don't know if all engines switched size when the 91 series started.
 
Unless IH has there own information wrong some 91 series must have a D-335 engine. Original bore sizes are shown beside the listing. Or the bore size for piston they were built with at the factory. D-335 and D-350 engines with bigger pistons than shown on the list had the oversize pistons added later at a rebuild. With sleeves removed 335 and 350 blocks have a different block bore. If a 4.5 piston goes in a 335 thin sleeves are used. When a 4.5 piston is in a 350 that's the size it was built with. Has a thicker sleeve than a 335 with 4.5 pistons.
Yes your engine is probably older with that head number.

so, in the 40's the D335 had different sleeves. Okay. Thanx
