possible to use an e30 PAS pump on an M52?

[alan1272]

i have a an m52 which i am putting into my e28 and the latest snag is that the banjo connections on the e28 pipe work do not correspond with the sizes on the m52 pump.

the problem is that the pressure line from the pump to the rack uses a 14mm banjo on the pipe and a 16mm one on the pump.

fitting a e30 (from an m20) pump that i have would solve the mismatched connection sizes; i just wondered if anyone has done this and if there is anything i need to watch for etc?

iv just come across this and does not look like you can swap the pumps so im engineering a banjo bolt that will screw into the m52/16mm pump but with a 30mm hex head and no holes, with the e30 female thred 14mm in the end of the bolt head so you can screw in the e30 banjo nut,, ill have it done by the weekend and post some pics..

that'd be great, thanks.

i did have a google for adapters to step the thread down from 16 to 14 but had no joy.

im going to try and machine one out of some hex bar,, like i said ill post some pics of how it turns out, you cant use normal reducers as theres only 2mm between them,,

How will you seal it between the adaptor and pump?

[BATTS91]

Locktite init , if im thinking right the adaptor would only need the thread and half the lengh .

Dan have you come acceoss this problem before ? As i haven't

[taylorstattoo]

its the azact same thead,, they usually have a copper washer on them but ill get some new ones..

[BATTS91]

Nono , you have the space on the bolt for the banjo still ;)

[taylorstattoo]

ha ha ,, ,,,,, ohh shitt... lol.. what have i done that for lol.. i see,,.. fuck it ill have make another.. will still work for now but will have to fit the big banjo in there to sill it,,, cant believe that, i thought i was being so cleaver,,,

[BATTS91]

It wont really work as it will probably piss juice allover the show under pressure . Just cut it down and re thread it to the correct length ?

[taylorstattoo]

true,,

[taylorstattoo]

that'd be great, thanks.
