O & R Engine Parts Diagrams & Maintenance Manuals

Recommended Posts

Here are some scans of the original parts diagrams that came with some of the Ohlsson & Rice engines I have.

 

This parts diagram covers the Compact engine models I, II, & III and dates from 1965.

And this parts diagram covers the model 13B252 engine with the newer square starter mechanism and dates from 1971/72.

Also here is a scan of the starter mechanism operating instructions from 1972, that came with some Little Wonder manuals I bought. This covers the series 13A starter mechanism with the retaining ring for the starter reel (earlier engines have a clip to retain the spring).

I do have a few more to scan and add in the future.

Here are some scans I have done for the Ohlsson & Rice model 20A engine.

 

Model 20A-256 diagram & parts list, undated, but must date to January 1971 or earlier.

Model 20A engine maintenance manual from August 1972.

Ohlsson & Rice Model 20A Maintenance Manual Aug 72.pdf

I haven't worked on any model 20A engines yet, so don't know if there are any errors in the above manual, if anyone finds any please post about it.

 

edit:

Error found in the model 20A engine maintenance manual, with part numbers for the Walbro carburetors ,I have a carb marked HDC6 with a right angled fuel inlet, but the manual shows an incorrect number below the picture.

Can anyone confirm if the other numbers are correct? I only have one engine of this type.

 

edit 2:
Second error found with 20A manual, page 2 says that the spring housing should be turned 1 to 1½ turns to wind the starter spring, figure 7 on page 4 says to turn spring housing 1½ to 2 turns, I don't know which is correct yet.

I've been busy scanning all the O&R information I have from 1961 for engines up to serial number 006072, here is the price list from August 1961, the instruction manual from November 1961 and the parts list (undated but probably from 1961). I've already uploaded the brochure (undated but probably from 1960/61) in this thread;

Here is a better quality pdf of the above pictures of the price list, instructions & parts list from 1961;

And a separate pdf of just the parts diagram which isn't very clear in the above pdf;

Here are the parts diagram pictures from September 1962 that I saved from the previous forum (I dont know who scanned them) the pictures are a bit hard to read as they are low resolution jpg files (which the forum software has automatically reduced in size further), I haven't found an original yet to create a better scan & pdf from.

Here is the starter mechanism repair service bulletin for engines up to serial number #099151, for engines after #099151 use the 1972 procedure from post #1. It may get confusing if the starter has been swapped in the past too.

Please don't post requests on this thread, start a new one and we can help.
