inner chaincase ??

happy new year people !!

does anyone know if there is a physical difference between the early inner chaincase and late one , the early one has a spacer in the middle (033270) but later does not .
im tryinmg to fit my cases to the bike but there is a gap between the gearbox shaft sleeve and the inner chaincase
the parts book lists 033130 as the inner but on my bike i have( casting ref inside ) 025017 . the outer is listed as 033135 but i have ( casting ref inside) 033136 .
i have all the correct spacers for engine and gearbox in the correct place and of the correct size .
i believe there are shims required to pack out the clutch basket to line up with the front primary sprocket , would these pack out the gap ???

thanks in advance
andy

another question please ...... what does the clutch basket butt up against ? it sits on the cluth shaft but that will spin at a different rate to the sprockt sleeve gear so it cannot butt up against that ? can it ?

thankyou
andy

the clutch basket has an inner shoulder that the shaft bottoms out on ! sorted that !!

Since no one has addressed this query, let me add what I know. According to the 1967 parts list, the inner cover (P/N 033130) and the early outer cover (P/N 033134) takes a spacer between the two halves (P/N 033140) measuring 3/4" x 1 1/2" x 3/8". The later parts list for 1968-69 shows an inner cover (P/N 033130), a different outer cover (P/N 033135) and a different spacer (P/N 033270) measuring 1/2" x 3/4" x 3/8".

What I don't understand is I have observed inner covers with longer bosses over the opening for the footpeg stud. However, there was only one part number (033130).

evening ron , thanks for the reply , i have now solved my problem , i misread some info relating to gearbox spacers and their position , now swopped them around and all is well , the chain cases i have are for the earlier p11 which have the inner separate spacer 033270 but that is only 1/2 inch thick not 3/8 the p11a (later ones) have the spacer cast into the case itself im lead to believe .

regards
andy

3/8 is the bore, not the thickness. The dimensions are from the "Stainless bits" spreadsheet. I assume they are 3/4 OD X 3/8 ID X 1/2 thick. The bigger spacer is 3/4 OD X 3/8 ID X 1 1/2. I cannot confirm these measurements, because the P11 on my stand doesn't have the primary installed yet. It did not have a primary assembly when I bought it. I haven't removed the primary on my Ranger, I have enough parts floating around and don't want to get any mixed up.

hi ron , yes those dimensions are correct 3/4 od 3/8 id and 1/2 long not sure which bigger spacer you are referring to , or do you mean the stud spacer from eng plate to inner chaincase ?
on a different note which wiring diagram are people using ? is there a specific one for the p11a or is it an atlas one ?????
cheers

From the 1967 P11 Parts List



According to the spreadsheet from "Stainless Bits" this spacer is 3/4 OD X 3/8 ID X 1 1/2 long. Perhaps this was used on the very early models with a G15/N15 inner primary casting and the casting was changed on later models to enlarge the boss where the footpeg stud opening is located, necessitating a shorter spacer?
