Installation Instructions for D-series engines w hydraulic Transmission into 88-91 Civic/ CRX.

For use with Innovative Mounts Conversion Kit Part # 49151

 

 Please Read: This kit is designed to bolt in D-series engines with Hydraulic transmissions into a 88-91

Civic or CRX. First make sure that if you are using a D-series engine from a 92-00 Civic that is has the

left-hand engine bracket from the 88-91 Honda Civic (the post bracket). If you need one it can be ordered

from us directly or from any Honda Dealer.


Engine bay preparation:

1. Test fit the rear mount on the rear engine cross-member.  The area of the rear cross-member may need to

be bent down to clear the rear engine bracket (T Bracket) that comes with this kit. Test fit the bracket

on the mount after bending the cross-member to make sure enough was bent down (Note: modification of the rear crossmember is not generally required with this kit, we add this more as a precaution).

2. You may choose to either use an aftermarket front crossmember or modify your existing one by cutting off the original engine mount bracket for the front mount at this point for added clearance. Also if you are using an aftermarket header you may need to modify your existing crossmember for clearance.


Hydraulic conversion installation:
Note: We recomend doing these steps before installing engine into the engine bay.

1. Bolt the release arm lever and bracket to the front of the transmission using the top two of three 12mm

boltholes on the front of the transmission.

2. Install the cable bracket using two 8mm x 1.25mm x 25mm bolts. Torque the bolts to 19 ft/lbs.


Mount kit and engine installation:

Note: We recomend removing the radiator from the car before installing the new engine so that it will not

be damaged. It will also allow for more space to maneuver the engine into place.

1. The rear mount should be bolted into position. Do not attach the rear bracket to the rear mount at this time. The rear bracket should be installed later, as the engine is lowered or raised into position. It is best to have help when doing this if you are installing the engine in from the top. You may need a box end wrench to tighten the rear bolt.


2. If you are installing the engine from the bottom, you can go ahead and install the right-hand mount on

the transmission. If you are installing the engine from the top, you will need to drop the engine down

below mounting position and then install the mount. Then raise the engine back into place while installing

the rear bracket. Do not completely tighten the bolts on the rear bracket yet. Notice the right-hand mount may have slotted holes where the mount bolts to the top of the mount does not line up perfectly the frame rail bracket you can use slotted holes to shift the mount to the right or left to compensate. This may or may not be necessary with your car. It depends on your vehicles past history and manufacturers tolerances.

3. Next install the left-hand engine mount, but do not completely tighten the bolts. Use a 12mm x 50mm

bolt and lock nut on the front bolthole and another lock nut on the stud. Make sure you also use 12mm

washers under the lock nuts.

4. Install the top bolts on the rear engine bracket where it meets the engine and the rear mount. Now go

back and tighten the mount bolts on the right and left mounts. Finally install the two bolts on the bottom

of the rear bracket where it meets the transmission and tighten all the bracket bolts. After 100-200 miles

of driving, check and re-torque all the mount bolts to factory specifications.

Note: We always recomend leaving all bolts finger tight until your engine is properly placed, with the

engine properly secured.

 

Clutch Cable Installation:

1. Make sure the clutch cable adjustment nut is adjusted all the way to the top first, and then slide the

clutch cable through the holder. Now raise the release lever up and slide the clutch cable into the

slotted end. Seat the clutch cable stop into the opening of the lever.

2.  Slide the release rod over the end of the release arm on the transmission as shown and tighten the

bolt until the wave-lock washer flattens completely.

3. Bolt the rod end of the release rod to the release lever.

4. Adjust the clutch cable adjusting nut as you would normally would for your car. After test-driving the

car, some additional adjusting may need to be done to get the clutch’s release point in the ideal

position.
