Hey. I have decided to do a write up regarding the removal of the ABC suspension pump on the CL models. I have done this because there is very little in the way of information of how to remove the actual pump. What very little is out there seems to be misinformation and regurgitated eighth hand rumor.
One such snippet of misinformation is that the pump is held onto the block with 3 bolts, there are in fact 4 that hold it onto the block. This from what i have read seems to be the general consensus. There are four gentlemen:thumb:
Please use this thread as a guide and use it an anyway you like and undertake your task in any order you choose. This is just the facts of what i have done first hand. The only so called special tools are a set of Star shaped sockets.
The whole job too me about one hour 15 mins.

The reason for the pump removal is to rebuild my pump with a new seal set i have. This is due to my pump spewing out oil at a very alarming rate. However as you will see at the end of the thread, the cause of the leak is much more easier to rectify than first thought.
1\ Loosen the front 3 star bolts from the front of ABC pump pulley before belt removal. [pic1]

2\ Remove the serpent belt from the pulleys. Make a note of there orientation.

3\ Remove belt tensioner by removing just two star bolts.

4/ Unclip the electrical connection. also for better access i chose to remove the little earth strap and removed the hose holding bracket.[pic2&5].

5\Remove banjo bolt 1&2 [pic 3&4]

6\The first rear bolt to remove is a star bolt which connects the bump to the engine block via a bracket. pic 6 shows the position on the rear star bolt via a socket i put on to show you. Pic 7 shows the socket on the ratchet. Pic 8 shows the bracket and pic 9 shows were the bracket attaches to the engine block under the cylinder heads.

7/ Now for this little bugger, its the 13mm standard nut also at the rear of the pump. Its very hard to see and i have tried to show you the location via pictures 10&11 and the location hole in pic 12. It can be easily got to from the top through the slot with a long 13mm spanner.

8/ Remove the two front star bolts. There locations ore shown in pic's 13.

9/ Remove the pump pic15....easy :)

10/ In picture 16 i have mocked all the attaching bolts and nut, along with the orientation of the support bracket.

11/ NOW THERES THE REASON FOR MY PUMP SPEWING OIL in pic 17 :D
A split reservoir.

Now you know:bannana:
