The original subject was "Re: Tec. HH60 Con. rod availability".

jerry from e iowa, I"m looking for a crankshaft for an 8hp Tecumseh HH60 10511 5H engine mounted on a Troy Bilt rototiller. The Tecumseh part # for the crankshaft is 34872. If you have one, e-mail me specifics. Thanks

actually it's a crankshaft for a 6 hp tecumseh engine, not an 8hp. Sorry.

If you don't get an answer from jerry,goto ebay & search item# 350577332801,see if it matches your's or ask seller pto shaft size & mod/spec# of eng(seller parting out an hh60),then goto link below & lookup eng in tecumseh eng section,check pn for crank to see if same pn as your's,tecumseh used several different pn cranks on hh60 depending on spec#.

Thanks - Joe Csuti

I went to the ebay item and there isn't any detailed information about engine spec # or part # or shaft size. Unfortunately when I tried to "ask a question" of the seller I got the following response from ebay.

"Unfortunately, this seller is not able to respond to your question. We suggest reviewing the item again to see if your answer is in the seller's listing."

I realize there is nothing I can do about this, but it's a bit frustrating cause the crankshaft looks and sounds like it might be the right one. Thanks again.

I was able to email seller,if your not registered on ebay or didn't sign in this may be why you got message.

I clicked on sellers handle & selected other from contact seller list,I asked about shaft diam/spec#,if he responds before end of auction,I'll post shaft size or spec# of eng.

I have had good luck ordering Tecumseh parts thru OUTDOOR DISTRIBUTORS. Google it. I think they are headquartered in Alabama.

Thanks Joe

I see under the Q&A list for "other" questions for this ebay item, that it certainly appears like you were able to ask a question for me and oregonduck1986 answered it.

Since it is not the same engine model # as mine, I still have a couple of additional questions to determine if his crankshaft will work for me, specifically the length of the drive shaft and the diameter of the journal.

However I still am not able to get a question through myself. I even called up ebay customer support, and they got the same error message I got when they tried to send a test message to oregonduck1986. So apparently he's not answering questions from them either.

So whatever you did, or whatever special privileges you seem to have, could I impose on you one more time to ask about the drive shaft length and the diameter of the journal.

Thanks - Gary

Thanks LenND

I tried OUTDOOR DISTRIBUTORS and they list the crankshaft as "Not Available" which is what I'm seeing from all of the normal parts distributers. I think a used one from somebody on e-bay is my best hope.

He answered me-shaft 3/4" diam,spec# 105106F

Sent him another email this morning,will have to see if he answers again,it's getting close to end of auction.

To clear up crank journal issue,now that have spec# of his eng,go back to partstree & look up your eng spec# and his,see if rod same pn for both.

Did he say if he measured it?

A lot of those old HH60s have the rod journal out of round and you can't turn them because there are no undersized rods - at least none that I have found.

Thanks again Joe - I did check the part # for the crankshaft for both mine and his and they're different. Does this mean that they are definitely different in size in some respect?

That's definitely the problem with my crankshaft. the journal is out of round, and I've broken two connecting rods as a result.

If I were you I would buy a replacement engine from the smallenginewarehouse. I bought a 10hp B&S from them in 2006 for my old tiller. I sold the 6hp engine for $65.00 and only paid $100.00 for the tiller. It needed new tines and seals under the tine holders. The engine also has electric start. Hal

I haven't received an answer yet as to journal size.

I did some checking while waiting & found as you did that cranks are different pn's,also rods are different pn,the difference may be shaft diam x length,different journal size(width or diam)or possibly wrist pin size or rod length,the only real way to tell is have both in front of you & measure both,also unfortunately seller not listing old rod/piston for sale.

Hal - This may be my only option if I can't find a crankshaft that will work.

Don't spend a lot of time educating me, but how do you know what replacement engine will work. I'm thinking of at least two things to consider. (1) Making sure that the replacement engine will be able to be bolted on to the tiller "engine mount" exactly as before. And (2) making sure that the engine pulleys and the tiller pulleys "line up" after mounting the engine on the tiller mount, which sounds like this means the drive shaft length has to be exactly the same as before? Are there other things one needs to consider, and can the people at a place like small engine warehouse tell which replacement engine will work just be giving them the old engine model #?

Thanks for any insight you can give me - Gary

Troybuilt tillers in early years used Kohler engines with cranks speced for generator use. Kohler strike lead to Tecumseh alternate as the emmediate available replacement with same generator use crank end. replacement Kohler engines are more available than the limited market model Tecumseh- and Kohler still in business, it will cost though. Briggs replacement engines in some catalogs don"t show replacement for the Tecumseh- but do show the replacement for Kohler application for tiller and generator use with the crankshaft spec. The later small Troybuilts with Briggs engines have slightly different drives- use the "plain" shaft standard to Briggs, some others including Honda utility engine designed to fit American "Inch" standards- need to find the thread where 6.5 hp Honda replaced 5hp Briggs on Troybuilt or the thread of use of Continental G61- engine used on Allis Gs- rod bearing on a .020 turned under crank- Kohler I think was the crank with note that Tec engine could in desperation get same machining, fit to turned crank. Generator sites may have the old tec crank spec yet. Small engine shop late 1970"s had many Tec short blocks sold for the Troybuilts working on slopes and failure of rod due to lack of oil splash at slant. Tec engines used on level ground gardens lasted long time, it seemed that the slanted ground use was main problem and Tecumseh had a little service warning, note on no warrantee to be given for the "commercial use/slanted fields".

i wouldn't waste the time on that old motor will cost you more in time an money just stick a new small briggs or kohler on it.simple to do

Go to small engine warehouse

http://www.smallenginewarehouse.com/

Click on the "repower old equipment" option and select what you want to repower.


If its a Troybilt Horse the options range from a $199 Briggs (roughly 5 hp) to a $595 Generac(15 HP).

I have one sitting on a scrap pile, Mount Vernon Iowa.

When you call you tell them you need a replacement engine for a Horse model Troy Bilt and they will tell which which engines will fit. Hal

Item 34 in this parts breakdown will then fit your new engine. Hal

Thanks Hal and dhermesc and rick54 and rn

Replacing the engine is begining to sound like a real viable alternative (to not being able to find a crankshaft that works)
