Default Scorpio Nozzle Service & general service

Date: February 26, 2010
Time: 10:00 am
ODO reading: 113408 Kms.

The Bull had run 79993 Kms since the last servicing was done in November and it was time to visit the FNG. One of the other compelling reasons being that on one of my aggressive runs on the NH8, I discovered bellows of smoke in the RVM when gunning from 115 to 120 & then from 120 to 125 kmph. The cloud vanished as I eased on the pedal and returned once again when I floored.

Mine being a non-CRDe, I did expect some smoke in comparison to CRDe but not this much. I had two doubts - choked silencer system or choked nozzles. Some of you may ask, why not choked air filter? Because I periodically clean the air filter - approximately every month.

Called Roshun and consulted and he seemed to concur with me on the nozzle issue.

So, yesterday armed with a 15 ltr bucket of Chevron Delo 400 & Chevron gear & differential oil I marched to my FNG.

Since I was quite early, only two more cars were standing in the bay. I asked Rakesh to take a TD to check for any other anomalies and after a detailed TD of about 3 kms he said - "gaadi to bilkul sahi chal rahi hai".

Well, happy with my self I sat back on the chair and servicing job began immediately after the job card was prepared by Rakesh. The first & the foremost was to remove the 4 diesel nozzles so that they could be sent for servicing. It took almost an hour to remove them and then 4 gleaming MICO-BOSCH nozzles were being stared at by me and Rakesh. The tip of the nozzles were black with soot and we could see some pores on each. BTW, each nozzle has 4 fine pores from which the fuel is sprayed in the chamber. The nozzles were sent for service to the local MICO centre and I was told the procedure which is as follows:

"Just like injectors of a petrol car is put on a machine and cleaned, similarly the nozzles too are put on a machine and checked for blockage & plunger pressure. Then the tip of the nozzle is opened and the plunger section unscrewed. The tip is sand blasted with fine sand and with a micro-thin wire the pores are cleaned. Assembled and checked again on the machine and sent back if found to be ok".

In the meanwhile the rest of the procedure started. Engine oil, Oil Filter, Diesel Filter and Gearbox & Diff oil were changed while the brake, PS & clutch oil were checked. Rear brakes were serviced, rear bumper painted, Nut-bolts tightened & silencer flushed. Only two days back I had replaced the stock foam air filter with K&N.

In the meanwhile the serviced nozzles arrived and following was the report:

First cylinder's nozzle: 2 out of 4 pores blocked
Second cylinder's nozzle: All 4 pores open
Third cylinder's nozzle: 1 out of 4 pore blocked
Fourth cylinder's nozzle: 1 out of 4 pore blocked

The nozzles were refitted, diesel pump activated to remove air from the fuel lines and the engine cranked. After 2 cranks it started. I felt the sound was a lot smoother and FNG also concurred. Could be psychological also. This would be dispelled later.

Checked for leakages and after all was found ok, the truck was taken to the washing bay. Here the old coolant was drained out and the radiator flushed thoroughly. 3 ltrs of Golden Cruiser coolant liquid was poured and then topped with distilled water. After washing & greasing, it was the AC guys turn to check the cooling system. He said that the gas required top-up and did so. Settled the bill and was ready to roll out at 2:30 pm. Total time spent at FNG - 4.30 hrs.

Now was the time to visit Deepak Kataria of Bridgestone Select at GGN for balancing, rotation & alignment. Within an-hour I was cruising on my way to work. The NVH was much lower, pick-up increased and the engine running smoother. Gunned for power from 110 to 120. No cloud. Happy Bull owner.

The cost breakdown:

Engine oil, Gearbox & Differential from Chevron was used from my stock, that I had hoarded before Chevron shut shop.

1. Chevron Delo 400 Engine oil - 6 ltrs
2. Chevron Automotive gear oil GL4 SAE90 - 2.5 ltrs
3. Chevron Automotive differential oil GL5EP SAE 85W~140 - 2.0 ltrs
4. Purolator oil filter - Rs. 110.00
5. MICO Diesel Filter set - Rs. 140.00
6. Golden Cruiser Coolant - Rs. 540.00
7. Two spare rear indicator bulbs - Rs. 20.00
8. Rear bumper denting & painting - Rs. 1000.00
9. Nozzle service - Rs. 350.00
10.AC gas top-up - Rs. 400.00
11.Servicing & labour - Rs. 800.00
12.Five wheel rotation, balancing & alignment - Rs. 400.00

TOTAL - Rs. 3760/-

Now I'm all set to face the scorching summer of Delhi/NCR...

I am going to trot across and get my injectors cleaned at the nearest MICO Centre. Thanks, GD, for the cue.

Hi GD,
That was really Informative.
I have a 203 End Non CRDE Chain Drive 2.6 Scorpio.
It has done around 70,000 kms.
I am thinking of the Nozzles serviced too. At my lat service at Bhasin Moors, I told them to do the Injector Cleaning, but they said they do not have the facility.
Can you please let me know the Contact details of your FNG and of the Mico Service Center too.
I stay in Vasant Kunj, and I think since you are in Gurgaon, it should not be too far for me too.
Thanks

No harm in using synthetic oil at 35K. Engine is fairly new. I hope you would be using Mobil.

But, if you start using synthetic, then stick to it and don't interchange with mineral or semi-synthetic. Synthetic oil is thinner and use of it at later stages, i.e. + 60 or 70K kms, could result in oil seal leakages. But if you continue using the same type then no harm.

A major typo error Dada. It should read as 7993 Kms.

Injector cleaning generally meant for CRDe models. The injector cleaning machine comes for a few crores, I'm told. Not many ASCs have this with them. Most of them do a chemical cleaning that is inadequate.

Nozzle cleaning instead is different and part manual as well. My FNG contact is Rakesh Sharma - 9811580697. He sent & got the nozzles serviced. I didn't go to the service centre personally.

The engine oil changing schedule changes once you start using synthetic. You shall need engine oil replacement after 15K kms.

I agree totally with you. Everywhere you need to have contacts. Why can't good service be a standard everywhere? Why do we ever need to have contacts?
