That is one that falls into a gray area. The model is 143302 which is 14 cu in. It would be somewhere in the 5 HP range, give or take a little. I've never seen a date chart for those early six digit engines prior to the use of the code number. It would fall in the late 50s to early 60s range.

Can't remember the numbers on mine but seems like that is the 1958 5 3/4 h.p. I'll have to check to be certain.

The 1962 and 1963 Bolens 600 tractors (and possibly 1964) used the B&S model 143302 engines.  ....They were advertised as 6hp.

142302 is the number for a 1958 5 3/4 horsepower.

this has been a topic before it's easier to date the tractor but roughly 58 to mid 60's . If I remember I think your panzer was a t70b from 1960

The 143302 was widely used and difficult to date. It is a 5 3/4hp, as mentioned, and these guys have the range nailed. I have one I have not been able to get spark to...im the 2 1/2 years Ive owned it. Every ignition component is has been replaced =(

Yup - This is a 143302 - 5.75 HP that is on my '59' DB I know the 60' DB had a 143402 Damn near the same motor ,

@mrgreen - I know it is a longshot - but my uncle got a bad condenser - new, but bad - gave him fits . Try another one.

or if you are ready to give up on it - I need a back-up motor! :D

I'm still trying to get a correct date on the Panzer tractor but I haven't had any luck with nailing it down with the tractor serial number yet so I thought I would try the engine.

 

About the only way you can set a date on the Bolens Ridemasters is by the serial number on the  Wisconsin engine.

you might want to contact dandy sales and ask Jim
also bill janitor? his Web site. someone had a partial spreadsheet with production dates and serial numbers. I would bet money yours is a 1960

I know my SN is 17690  -  now the 143402 on my uncles 60' is SN 51741  402 denotes a slightly different stroke or bearing and crank set- (I think)

I think it would be closer to a 61' but I am not sure.

402 is for a mechanical governor not the airvane setup otherwise the engine is the same

Are you sure ? - Because my 302 has/had a mechanical gov.

003 (2).jpg

My Uncle used his 302 w/ Airvane as a template and made an airvane gov.  for this engine.

Works great too BTW :D

We had the book out and went thru the #s - I thought sure he said the #4 indicated something to do with a gear or crank difference.

Anyway - We have done 2 of these motors and I have to say they are a real Gem of a motor. The one on my machine runs great now .

Starts easy , I have no history on the tractor but it had to have sat for a very long time .

Back in those days they were changing things on the fly - My engine has openings on both front and back for oil check - his has only the front -on his 60' has it only on the back .

Hold on - My Uncle just called and is going to get his book for this.....

14= CID

3=design series related to cyl. construction

3=position of crank shaft and type of carb.

0= type of bearings -equipt with reduction gear or aux drive

2=type of starter = rewind
